Rubic

Rubic is a cross-chain aggregator that consolidates access to decentralized exchanges, bridges, intent-based protocols, and privacy solutions across more than 70 blockchains into a single non-custodial interface. It was launched in September 2020, during the height of DeFi Summer, at a time when executing a swap that involved more than one blockchain required manually navigating separate DEXs and bridge protocols—each with its own interface, wallet connections, and fees. Rubic was built to collapse that workflow into a single transaction.

The Problem: Fragmented Multi-Chain Liquidity

In 2020 and through subsequent years of multi-chain expansion, DeFi users faced a compounding coordination problem. Moving value from one blockchain to another required finding a bridge, executing a transfer, waiting for confirmations, then finding a DEX on the destination chain to complete the swap. Each step introduced slippage, fees, and failure points. As the number of active chains grew—Layer 2 rollups, Solana, non-EVM networks, privacy chains—the fragmentation worsened. Rubic's core thesis was that aggregation at the routing layer could abstract this complexity entirely.

How It Works

Rubic operates as a routing and aggregation layer rather than as a liquidity venue of its own. When a user initiates a swap, Rubic's smart routing engine queries its integrated providers—340+ DEXs, bridges, intent protocols, and privacy solutions—and identifies the optimal execution path across the integrated liquidity. That path may involve multiple hops across different chains and protocols, but it is packaged into a single transaction the user signs once.

Critically, the architecture is non-custodial: funds never pass through Rubic's own contracts in a holding capacity. Every transaction is executed by sending API calls to the smart contracts of the underlying providers. As the documentation states, "your funds always stay in your wallet and never on app.rubic.exchange."

Rubic also addresses what it describes as four layers of chain abstraction. The "All Chains" feature aggregates a user's token balances across all connected networks into a single view. Multi-hop routing executes cross-chain transactions as atomic or near-atomic sequences rather than manual multi-step processes. Intent-based protocols are integrated to allow automated relayers to fulfill user swap intents across 360+ providers. And non-EVM chain support—covering networks like Solana, Bitcoin, and TON—is handled without requiring users to maintain separate wallet sessions for each network.

Key Features

The platform supports more than 70,000 tokens and over 1,000,000 trading pairs across its integrated networks. Coverage includes EVM-compatible chains, Layer 2 networks (Arbitrum, Optimism, Base, zkSync, Linea), and non-EVM chains including Solana, Bitcoin, and TON. Rubic integrates privacy-preserving swap routes that route through solutions supporting assets such as Monero and ZCash, aimed at users seeking portfolio confidentiality against copytrading or front-running.

A developer API and SDK are available for dApps seeking to embed cross-chain swap functionality without building their own routing infrastructure. The SDK has been adopted by over 160 partner crypto brands according to Rubic's published figures. In June 2025, Rubic launched a Model Context Protocol (MCP) server, extending its swap routing to AI agents—enabling automated cross-chain transaction execution from within AI workflows.

Solana Integration

Rubic integrates Solana as both a source and destination chain for cross-chain swaps. On-chain Solana swaps route through aggregated liquidity across Solana DEXs including Raydium. Cross-chain swaps to and from Solana are handled by Rubic's integrated bridge providers, allowing users to move assets such as SOL, USDC, and other SPL tokens between Solana and external chains in a single interface operation. Rubic received recognition from the Solana Superteam in 2025, reflecting the platform's growing integration with the Solana ecosystem.

RBC Token

RBC is Rubic's native utility token, deployed as an ERC-20 on Ethereum with a maximum supply of one billion tokens. The token serves multiple functions: governance voting on protocol proposals, staking to earn a share of platform fees (distributed in ETH), participation in partner airdrop programs, access to SDK integration grants, and discounted fee tiers. The token was relaunched with updated tokenomics tied to SDK subscription economics and governance participation.

Security and Audits

Rubic's smart contracts were audited by MixBytes, a blockchain security firm. The audit identified two critical, two medium, and one low severity findings. Following remediation, the two critical issues and one medium issue were fixed; the remaining medium finding was reclassified to low severity and acknowledged. No critical or high severity issues remained unresolved after the audit.

For treasury and staking contract management, Rubic uses a Gnosis Safe multisig wallet requiring 3-of-6 signers to authorize transactions. The platform also operates a bug bounty program through Immunefi, employs a CISO, maintains two-factor authentication on production infrastructure, and runs monitoring systems with anomaly alerts. Code is published open-source for community review.

The distributed provider architecture—routing through 340+ independent protocols—provides an additional operational resilience property: the failure or compromise of any individual provider does not take down the aggregation layer.

Team and Background

Rubic was co-founded by Vladimir Tikhomirov and Alexandra Korneva. Tikhomirov previously 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. The team is internationally distributed, with members based in Eastern Europe, Germany, the United Arab Emirates, and the United States. Key roles include CTO Eugene Korol, CMO Elena Nova, and CBDO Sven Michael.

The project's initial funding was approximately $500,000 (raised as 1,800 ETH in 2020). Subsequent support has come through ecosystem grants from Polygon, Arbitrum, and NEAR. Rubic was selected for the Consensys Scale Program in 2024 and for the Sony Incubation Program, providing technical support and go-to-market resources.

Ecosystem Position

Rubic serves over 500,000 users by its own published metrics and has processed transactions across an ecosystem of 130+ integrated dApps. Its position in the Solana ecosystem is as an external entry and exit point: users on other chains can route into Solana-native assets via Rubic, and Solana users can access liquidity on other chains without managing multiple bridge interfaces. The platform's MCP server integration positions it as infrastructure for the emerging AI-agent DeFi layer, where autonomous agents need programmatic access to cross-chain liquidity routing.
