Rubic Exchange

Founding

Rubic Exchange was founded by Vladimir Tikhomirov, a software industry executive with over 22 years of experience in technology and more than a decade of building companies internationally. Before establishing Rubic, Tikhomirov founded MyWish, a smart-contract management platform that operated from 2017 to 2024, and DDG, a software development company based in Finland. His earlier career included roles at Motorola and Oberon Media, giving him a broad background in project management, software engineering, and product development.

Alexandra Korneva co-founded Rubic Exchange alongside Tikhomirov. Together, they assembled an internationally distributed team with members based across Eastern Europe, Germany, the United Arab Emirates, and the United States. Key team members include CTO Eugene Korol, CMO Elena Nova, and CBDO Sven Michael.

The founding vision behind Rubic Exchange emerged from a recognition that the multi-chain nature of the cryptocurrency ecosystem created severe fragmentation for end users. In 2020, the process of moving tokens between different blockchains required users to navigate multiple bridges, compare rates on separate DEXs, and manage transactions across different wallet interfaces. Rubic was conceived as a solution to this complexity—a single interface where any token on any chain could be swapped for any other token on any other chain with a single click.

Development Timeline

Rubic Exchange launched in September 2020, initially supporting a limited number of chains and DEXs. Over the following years, the platform expanded its coverage dramatically, steadily adding support for new blockchains, integrating additional DEXs and bridge protocols, and refining its routing algorithms.

By 2022, Rubic had established itself as one of the leading cross-chain aggregators in the decentralized finance (DeFi) space, supporting dozens of blockchains and hundreds of liquidity providers. The platform introduced its SDK and widget products during this period, enabling third-party projects to embed Rubic's cross-chain swap functionality into their own applications.

The year 2024 marked a period of significant growth for Rubic. The platform processed over 828,000 transactions, representing a 97% year-over-year increase. Trading volume reached $391.5 million, an 82% improvement from the prior year, with 369,000 unique wallets interacting with the protocol. During this same period, Rubic expanded to support over 70 blockchains and integrated more than 340 DEXs, bridges, and intent-based protocols.

In parallel with the development of the Rubic Exchange, founder Vladimir Tikhomirov also launched Algebra Finance in May 2021, a DEX engine project built to power concentrated liquidity solutions on multiple chains. Algebra and Rubic operate as complementary projects within the broader ecosystem.

Cross-Chain Aggregation

At its core, Rubic Exchange functions as an aggregator of aggregators. Rather than operating its own liquidity pools or maintaining reserves of tokens, Rubic connects to a vast network of underlying decentralized exchanges, cross-chain bridges, and intent-based protocols. When a user wants to swap a token—whether on the same chain or across different chains—Rubic queries all of its integrated providers simultaneously to identify every possible route for that trade.

This aggregation model is particularly valuable in the fragmented multi-chain DeFi landscape. Liquidity for any given token pair may be spread across dozens of DEXs on multiple chains, each offering different rates, slippage profiles, and gas costs. A swap that appears expensive on one DEX may be substantially cheaper through a different route that involves bridging to another chain, swapping on a more liquid DEX there, and bridging back. Rubic automates this entire analysis, evaluating hundreds of potential routes in real time and presenting the user with the best option.

The platform supports both on-chain swaps (exchanging tokens within the same blockchain) and cross-chain swaps (exchanging tokens between different blockchains). For on-chain swaps, Rubic aggregates DEXs on the source chain. For cross-chain swaps, Rubic identifies a combination of DEX swaps and bridge transfers that yields the best overall rate and executes the entire sequence as a unified operation.

Best Rate Finder

The "best rate finder" is one of Rubic Exchange's defining features. When a user enters the details of a desired swap—specifying the source token, the destination token, and the amount—Rubic's routing engine evaluates all available paths through its network of 340+ integrated providers. The engine factors in multiple variables including the exchange rates at each provider, the gas costs on the relevant blockchains, bridge fees for cross-chain transfers, potential slippage based on liquidity depth, and the estimated completion time for each route.

After this multi-dimensional analysis, Rubic presents the user with the optimal route. In many cases, the best rate may involve routing through an intermediate chain or splitting the swap across multiple providers. The user sees only the final result—the expected output amount and estimated fee—while the underlying complexity is abstracted away.

This approach consistently identifies rates that are better than what a user would find by manually checking individual DEXs or bridges. Because Rubic scans such a wide range of providers across so many chains, it can discover arbitrage-like opportunities where liquidity imbalances between platforms create price advantages that are invisible to users operating within a single chain or DEX.

Transaction Execution Process

A typical transaction on Rubic Exchange follows a structured three-stage process. In the first stage, known as the quote phase, the Rubic system calculates all available routes for the requested swap and returns a quote showing the expected output amount, fees, estimated time, and the specific providers involved in the optimal route.

In the second stage, the execution phase, Rubic generates the specific blockchain transaction instructions needed to carry out the swap. For simple on-chain swaps, this involves a single transaction sent to the appropriate DEX contract. For cross-chain swaps, the process may involve multiple sequential steps: an initial swap on the source chain (if the source token is not bridge-compatible), a bridge transfer to the destination chain, and a final swap on the destination chain to the desired token.

The third stage is the status tracking phase. For cross-chain swaps that involve bridge transfers, there is inherently a delay between the initiation on the source chain and the completion on the destination chain. Rubic provides real-time status tracking across chains, allowing users to monitor the progress of each step. The platform supports various execution models including EVM contract-based swaps, EVM deposit-based swaps, non-EVM native transactions (for chains like TON, TRON, Solana, and Sui), and manual deposit-based execution.

EVM-Compatible Chains

The majority of blockchains supported by Rubic are EVM-compatible (Ethereum Virtual Machine), meaning they share the same smart contract execution environment as Ethereum. This compatibility allows Rubic to utilize a standardized set of smart contract interactions across these chains, simplifying integration and providing a consistent user experience.

Major EVM-compatible chains supported by Rubic Exchange include Ethereum, BNB Chain (formerly Binance Smart Chain), Polygon, Avalanche C-Chain, Fantom, Cronos, Gnosis Chain, Celo, Moonbeam, Moonriver, Harmony, Aurora, and Metis. Each of these networks has its own ecosystem of decentralized applications, and Rubic's integration with DEXs on each chain means that users can access deep liquidity pools native to every supported network.

Non-EVM Chains

In addition to EVM chains, Rubic Exchange supports several non-EVM blockchains, each of which uses a fundamentally different architecture and smart contract language. These include Solana, which uses the Sealevel runtime; TON (The Open Network), originally developed by the Telegram team; TRON, known for its high throughput and low fees; and Sui, a newer chain built on the Move programming language.

Supporting non-EVM chains presents unique technical challenges because the transaction formats, wallet types, and smart contract interfaces differ significantly from EVM standards. Rubic addresses these challenges through specialized transaction handling for each non-EVM chain, including native transaction support that eliminates the need for users to switch wallets or use separate interfaces when swapping tokens on these networks.

Layer 2 Networks

Rubic Exchange provides comprehensive support for Layer 2 scaling solutions built on top of Ethereum. These networks are designed to process transactions more quickly and at lower cost than Ethereum mainnet while inheriting its security guarantees. Supported Layer 2 networks include Arbitrum, Optimism, Base, zkSync Era, Polygon zkEVM, Linea, Scroll, Mantle, and Blast.

Layer 2 support is particularly significant for Rubic users because many of these networks offer gas fees that are orders of magnitude lower than Ethereum mainnet. By enabling seamless swaps between Layer 2s—and between Layer 2s and other chains—Rubic allows users to take advantage of the cost savings offered by these scaling solutions without being confined to a single Layer 2 ecosystem.

One-Click Cross-Chain Swaps

Rubic Exchange pioneered the concept of one-click cross-chain swaps when it launched in 2020, and this feature remains central to the platform's value proposition. Before aggregators like Rubic existed, performing a cross-chain swap required a user to execute multiple separate transactions: first swapping the source token for a bridge-compatible asset on the source chain, then initiating a bridge transfer to the destination chain, waiting for the bridge to finalize, and finally swapping the bridged asset for the desired destination token on the destination chain.

Rubic compresses this entire multi-step workflow into a single user action. The user selects the source token and chain, selects the destination token and chain, enters the desired amount, and confirms the swap. Rubic's smart contracts and routing engine handle all intermediate steps automatically. From the user's perspective, it is as straightforward as a simple same-chain swap, even though the underlying mechanics may involve multiple transactions across multiple networks.

This simplification dramatically lowers the barrier to entry for cross-chain trading, making it accessible to users who may not have the technical knowledge or patience to navigate the manual process. It also reduces the risk of user error, which can lead to lost funds when bridge transfers are executed incorrectly.

Chain Abstraction

Chain abstraction is a design philosophy that Rubic Exchange embraces to remove the complexity of interacting with multiple blockchains. The concept encompasses several layers of abstraction that collectively create a unified trading experience regardless of which chains are involved.

Asset management abstraction means that users can view and manage tokens across all supported chains from a single interface, without needing to switch between different chain-specific dashboards or wallet views. Transaction abstraction enables multi-hop swaps—transactions that route through intermediate chains or involve multiple swap and bridge steps—to be executed as a single operation from the user's perspective. Wallet abstraction eliminates the need for users to switch wallet networks when interacting with non-EVM chains, further simplifying the cross-chain experience.

The practical effect of chain abstraction is that Rubic users can treat the entire multi-chain ecosystem as a single unified liquidity pool. Whether a user's desired token pair involves Ethereum and Solana, BNB Chain and Arbitrum, or Polygon and TON, the swap process looks and feels the same.

Zero Protocol Fees

Rubic Exchange offers zero protocol fees for all swaps under $100, a policy designed to make cross-chain trading accessible to users with smaller portfolios. For swaps above the $100 threshold, Rubic applies a dynamic fee ranging from 0.3% to 1%, with the exact percentage depending on the complexity of the route and the providers involved.

It is important to distinguish Rubic's protocol fees from the underlying network gas fees and bridge fees, which are set by the respective blockchains and bridge protocols. While Rubic can optimize routing to minimize these costs, they are not within Rubic's control. The zero-fee policy applies specifically to Rubic's own service charge, making the platform one of the most cost-effective options for small and medium-sized cross-chain trades.

Rubic's fee structure also supports its low entry barrier philosophy. Users can initiate trades starting from as little as $0.50, while simultaneously supporting high-value transactions worth millions of dollars. This range makes Rubic suitable for both retail traders and institutional participants.

Non-Custodial Architecture

Rubic Exchange operates on a fully non-custodial architecture, meaning the platform never takes custody of user funds at any point during the swap process. All transactions are executed through smart contract calls to underlying DEX and bridge protocols, with assets flowing directly from the user's wallet through the smart contract pipeline and into the destination wallet.

This is a critical distinction from centralized exchanges, where users must deposit funds into exchange-controlled wallets before trading. With Rubic, the user's private keys remain under their control at all times, and no third party has the ability to freeze, seize, or access user assets. The non-custodial model eliminates counterparty risk—the risk that the exchange itself could be hacked, become insolvent, or engage in misconduct with user deposits.

Rubic's architecture is designed so that even the Rubic team itself cannot access or interfere with user transactions. The platform functions as an intermediary routing layer that connects users with decentralized liquidity providers, rather than as a custodian of user assets.

No KYC Required

Unlike centralized exchanges that require users to verify their identity through KYC procedures—typically involving government-issued identification documents and proof of address—Rubic Exchange requires no registration, no account creation, and no identity verification of any kind. Users simply navigate to the platform, connect their preferred cryptocurrency wallet, and begin trading immediately.

This permissionless approach aligns with the core principles of decentralized finance, where access to financial services is not gated by institutional approval. It also means that Rubic is accessible to users worldwide, including those in regions where access to traditional financial infrastructure or centralized crypto exchanges may be limited.

Tokenomics

The RBC token is the native utility token of the Rubic Exchange ecosystem. It was initially created as an ERC-20 token on the Ethereum blockchain, and it serves multiple functions within the Rubic platform including governance, staking, and fee sharing.

RBC has a maximum supply cap of 1,000,000,000 (one billion) tokens. As of the most recent reporting period, the circulating total supply was approximately 187 million tokens, with the remaining supply allocated to development, ecosystem incentives, team vesting, partnerships, and reserves. The relatively low circulating supply compared to the maximum supply reflects Rubic's approach to gradual token distribution tied to ecosystem growth milestones and strategic initiatives.

Token Utility

The RBC token serves several utility functions within the Rubic ecosystem:

• Governance: RBC holders can participate in decentralized governance through voting on protocol proposals, feature priorities, and ecosystem direction. This gives the community a direct voice in how the Rubic platform evolves over time.
• Staking and Fee Sharing: Users can stake their RBC tokens to earn a share of the protocol fees generated by swap transactions on Rubic Exchange. In 2024, over 34 million RBC tokens were staked by users, with an average annual percentage rate (APR) of 70%.
• Partner Airdrops: RBC holders are eligible to receive airdrops from Rubic's partner projects, providing additional value beyond the token's core utility within the Rubic platform.
• SDK Integration Grants: A portion of RBC tokens is allocated to grant programs for developers and projects that integrate Rubic's SDK, incentivizing the expansion of the Rubic ecosystem.
• Loyalty Programs: Rubic operates various loyalty and incentive programs that reward active users and RBC holders, creating a flywheel effect that encourages platform engagement.

Exchange Listings

The RBC token is listed on several centralized and decentralized exchanges. On the decentralized side, RBC is available on Uniswap V2 (Ethereum) and various DEXs on chains where it has been bridged. Centralized exchange listings include Kraken, MEXC, and ProBit, among others. Additional liquidity has been established on Arbitrum to support the platform's staking program on that network.

Staking Overview

Rubic Exchange offers a staking program that allows RBC token holders to lock their tokens in smart contracts and earn rewards in return. Staking serves a dual purpose: it provides token holders with a passive income stream, and it aligns the interests of token holders with the long-term success of the Rubic platform by reducing circulating supply and incentivizing long-term holding.

The staking mechanism is powered by smart contracts that have been secured through Gnosis Safe multisignature wallets, adding an additional layer of security to staked funds. When users stake their RBC tokens, they receive xRBC tokens in return as a receipt, which can be unstaked or transferred as needed. There is a mandatory 24-hour waiting period after staking before withdrawals can be processed.

Staking on Arbitrum

Rubic's primary staking program operates on the Arbitrum network, chosen for its low gas costs and fast transaction finality. The Arbitrum staking program offers several lock period options: 3 months, 6 months, 9 months, and 12 months. Longer lock periods are rewarded with higher APR, incentivizing extended commitment to the ecosystem.

When staking on Arbitrum, users receive a transferable NFT that serves as a receipt documenting the staked amount and lock period. This NFT-based receipt system enables secondary market activity and provides proof of stake without requiring direct interaction with the staking contract. The minimum staking requirement on Arbitrum is just 1 RBC, making the program accessible to holders of any size.

Users who hold RBC on other chains such as Ethereum can bridge their tokens to Arbitrum through Rubic's own cross-chain swap functionality before staking. The bridging process from Ethereum to Arbitrum typically completes within 10 minutes to one hour. Withdrawals from Arbitrum back to Ethereum require a minimum 8-day withdrawal period, which is inherent to the Arbitrum network's security model.

Rewards and APR

Staking rewards on Rubic are funded by 50% of the protocol fees earned through swap transactions. Rewards are paid out weekly in ETH, providing stakers with a tangible, high-demand asset rather than additional protocol tokens. The APR ranges from approximately 30% to 100%, varying based on the chosen lock period, total amount staked in the protocol, and overall platform trading volume.

The ETH-denominated reward structure distinguishes Rubic's staking program from many competing protocols that pay rewards in their own native tokens, which can create inflationary pressure. By paying in ETH, Rubic ensures that staking rewards have intrinsic value independent of RBC token price movements, making the program attractive to a broader range of investors.

Smart Contract Audits

Rubic Exchange's smart contracts have been audited by MixBytes, a reputable blockchain security firm specializing in smart contract analysis. The audit process involves a comprehensive review of the contract code to identify potential vulnerabilities, logic errors, reentrancy risks, access control issues, and other security concerns. The audit findings are addressed before contracts are deployed to production, and the audit reports are made available for public review.

In addition to formal audits, Rubic maintains an open-source codebase, allowing independent security researchers and developers to review the code at any time. This transparency-first approach means that the platform's security is not solely reliant on paid auditors but benefits from the scrutiny of the broader developer community.

Security Architecture

Rubic's security architecture is built on four foundational principles: sustainability, decentralization, performance monitoring, and accident management.

Sustainability refers to the platform's redundant design across 340+ providers. If any individual DEX or bridge provider experiences a security incident, is temporarily offline, or is compromised, Rubic's routing engine automatically excludes that provider and redirects traffic through alternative routes. This redundancy ensures that a failure or exploit in a single provider cannot halt the platform or expose user funds.

Decentralization in Rubic's architecture means that the platform operates without external servers beyond the frontend and the blockchain networks themselves. By minimizing the number of centralized components, Rubic reduces the attack surface available to malicious actors. There are no centralized databases, no centralized order books, and no server-side custody of user assets.

Performance monitoring encompasses Rubic's systems for tracking the health and reliability of its integrated providers. This includes provider scoring based on historical success rates, detection of stuck transactions, automated monitoring of social media channels for reports of bridge or DEX exploits, and real-time alerts for unusual activity.

Accident management protocols define Rubic's response procedures when security incidents occur at integrated providers. These include immediate notification to all integrators who embed Rubic's SDK or widget, automatic switching to alternative providers for affected routes, and coordination with the affected provider to assess the scope and impact of any incident.

Bug Bounty Program

Rubic Exchange maintains a bug bounty program through Immunefi, one of the leading bug bounty platforms in the blockchain industry. The program incentivizes security researchers to responsibly disclose vulnerabilities by offering financial rewards for valid findings. This proactive approach to security helps Rubic identify and patch potential issues before they can be exploited by malicious actors.

Provider Redundancy

The modular architecture of Rubic Exchange—consisting of distinct modules for cross-chain operations, on-chain operations, status management, token management, and revert management—is designed so that core functions continue operating even if individual modules encounter problems. If the cross-chain module experiences an issue, on-chain swaps continue to function normally. If a specific bridge provider is compromised, alternative bridges are automatically selected.

This compartmentalized design philosophy extends to the platform's integrated providers as well. With over 340 DEXs and bridges integrated, Rubic has built-in redundancy at every layer. The loss of any single provider has minimal impact on the platform's overall functionality, as routes are dynamically recalculated using the remaining available providers.

API

Rubic provides a comprehensive REST API that allows developers to programmatically access the platform's cross-chain swap functionality. The API supports all of the same operations available through the web interface, including fetching quotes, executing swaps, and tracking transaction status across chains. It is designed for integration into trading bots, portfolio management tools, mobile applications, and other software that benefits from cross-chain swap capabilities.

The API processes transactions through three primary endpoints corresponding to the platform's core workflow: a quote endpoint that calculates optimal routes and expected output for a given token pair, an execution endpoint that generates the blockchain transaction instructions for the recommended swap, and a status endpoint that provides real-time updates on cross-chain transaction progress.

SDK

The Rubic SDK (Software Development Kit) provides a more integrated approach for developers who want to embed cross-chain swap functionality directly into their applications. The SDK abstracts away the complexity of interacting with the API, providing high-level functions and type-safe interfaces that simplify development. It is available as an npm package and supports modern JavaScript and TypeScript development workflows.

The SDK is suitable for a wide range of applications including crypto wallets, decentralized applications (dApps), blockchain games, launchpads, NFT marketplaces, GameFi projects, and metaverse platforms. By integrating the Rubic SDK, these applications can offer their users the ability to swap tokens across 70+ blockchains without building their own cross-chain infrastructure. The SDK provides access to over 15,500 tokens across all supported networks.

Widget

For projects that want the simplest possible integration, Rubic offers an embeddable swap widget. The widget is a self-contained user interface component that can be added to any website with a few lines of code. It provides the full Rubic swap experience—token selection, rate comparison, and swap execution—within a customizable iframe or web component that matches the host site's design.

The widget is particularly popular among crypto projects that want to offer token swap functionality on their own websites without redirecting users to external exchanges. Project teams can customize the widget's appearance, restrict it to specific tokens or chains, and configure fee sharing arrangements to generate revenue from swaps executed through their embedded widget.

Partner Ecosystem

Rubic Exchange has been integrated by more than 160 web3 projects, forming a substantial partner ecosystem. These integrations span a diverse range of project types including decentralized exchanges, wallets, portfolio trackers, trading bots, and blockchain infrastructure platforms.

Notable integration partners include Best Wallet, HoldStation, DODO, Blum, Exolix, PortalX, DegenX, and NFA Trading Bot, among many others. Some partners integrate through the SDK for deep, native integration, while others use the API for backend swap functionality or the widget for quick frontend implementation.

The breadth of the partner ecosystem creates a network effect: as more projects integrate Rubic, more users are exposed to the platform, which in turn attracts more projects seeking to leverage Rubic's established user base and cross-chain infrastructure. This flywheel has been a significant driver of Rubic's growth in transaction volume and unique wallet count.

Connecting a Wallet

To begin using Rubic Exchange, a user needs only a cryptocurrency wallet that supports the blockchain they wish to trade on. The platform supports all major wallet providers including MetaMask, WalletConnect-compatible wallets, Coinbase Wallet, Trust Wallet, and others. No account creation, email registration, or identity verification is required.

Upon navigating to the Rubic Exchange application, users click the wallet connection button and select their preferred wallet provider. The wallet prompts the user to approve the connection, after which the Rubic interface displays the user's token balances and enables swap functionality. The entire connection process takes seconds and does not grant Rubic any control over the user's funds or private keys.

Performing a Swap

Once a wallet is connected, performing a swap on Rubic Exchange follows a straightforward process. The user selects the source token they wish to swap from, including the blockchain it resides on, and then selects the destination token they wish to receive. After entering the desired swap amount, Rubic's routing engine queries all available providers and displays the best available rate, including estimated fees and completion time.

If the user is satisfied with the quoted rate, they confirm the transaction in their wallet. For same-chain swaps, the transaction typically completes within the normal block confirmation time of that chain—usually seconds to minutes depending on the network. The swapped tokens appear in the user's wallet automatically upon completion.

Cross-Chain Swaps

Cross-chain swaps follow the same user-facing process as same-chain swaps, with the key difference being that the source and destination tokens reside on different blockchains. The user selects the source chain and token, then selects a different chain for the destination token. Rubic handles all bridging and intermediate swaps automatically.

Cross-chain swaps may take slightly longer than same-chain swaps due to the time required for bridge transfers between networks. Completion times vary depending on the specific chains and bridge protocols involved, ranging from under a minute for fast bridges between Layer 2 networks to 10–30 minutes for transfers involving chains with longer finality times. Rubic provides a status tracker that allows users to monitor the progress of their cross-chain swap in real time, with updates at each stage of the multi-step process.

Users should be aware that cross-chain swaps require sufficient gas tokens on the source chain to pay for the initiating transaction. The destination-side gas is typically covered by the bridge protocol or factored into the swap routing, so users do not need to hold gas tokens on the destination chain in advance.
