Rubic

Rubic launched in September 2020 as a cross-chain aggregator, a protocol that routes token swaps through whichever combination of decentralized exchanges and bridges offers the best rate at the time of execution. Rather than requiring users to manually compare rates across platforms and perform separate transactions on different networks, Rubic's smart routing layer finds the optimal path and executes multi-hop swaps in a single transaction. The platform has grown to support 70+ blockchains, 340+ integrated DEXs, bridges, and intent protocols, and over 70,000 tokens, making it one of the more comprehensive aggregation layers in the multichain ecosystem.

How the Aggregation Works

Rubic's core function is transaction abstraction. When a user initiates a swap, the protocol evaluates available liquidity sources, compares routing paths, factors in slippage and gas costs, and executes through the best provider—without the user needing to identify or interact with that provider directly. Cross-chain swaps execute in single multi-hop transactions, and users swapping to non-EVM chains only need to supply the destination address rather than switching wallets or networks.

The aggregator's scope covers both same-chain and cross-chain activity. For same-chain swaps, Rubic routes through the deepest liquidity on the target network. For cross-chain transactions, it selects from more than 200 bridging solutions to move assets between chains. The platform supports non-EVM chains alongside the standard EVM ecosystem, including privacy networks such as Monero, ZCash, and Dash for users who require transaction privacy.

A privacy-first swap option is also available for on-chain activity, enabling users to obscure wallet activity from copytrading bots and on-chain trackers—a feature increasingly relevant on transparent public networks.

Solana Integration

Rubic added full Solana support with a zero-protocol-fee model for all Solana swaps. Users can bridge Solana-native assets to 18+ destination networks including Arbitrum, Base, Optimism, Polygon, NEAR, TRON, TON, and Bitcoin. Supported Solana assets include SOL, USDC, USDT, BONK, RAY, JTO, JUP, RENDER, PYTH, and FRAX, among others.

In August 2025, Rubic integrated Jupiter as its fifth on-chain provider and its first DEX aggregator on Solana. Jupiter's routing engine evaluates token pair availability, liquidity depth, slippage risk, and gas costs in real time, and stacking it within Rubic's cross-chain routing layer adds an additional optimization pass for Solana-originated swaps. The integration is part of Rubic's stated goal of aggregating 15 top Solana DEXs and bridges on the platform. Rubic is also a Solana Superteam alumni project, reflecting sustained participation in the Solana developer community.

Fee Structure

Rubic charges zero protocol fees on swaps under $100, zero fees on stablecoin and native token on-chain swaps, and zero fees on all Solana swaps. Larger cross-chain transactions carry variable fees depending on the route and provider used. The RBC token offers additional fee discounts for holders. This structure is designed to keep small and routine swaps accessible while generating protocol revenue on higher-value transactions.

Developer Tools: SDK and API

A significant portion of Rubic's activity comes not from direct users but from projects that embed Rubic's swap infrastructure into their own interfaces. The SDK provides access to the same 340+ providers and 70,000+ tokens through a single integration that the team estimates takes 30 minutes for a basic implementation and two to three days for a fully customized build. Integration is free, and Rubic shares a portion of its protocol revenue with partners who generate volume.

Q1 2025 saw integrations from Dodo.exchange, Emperor's Seal, NFA Trading Bot, SimpleSwap, TeleSwap, and Bridgers.xyz. In 2024, BestWallet and Holdstation adopted the API for cross-chain swaps within their own platforms. The platform reported 160+ crypto brands using its infrastructure as of mid-2025.

Volume and Scale

Rubic processed $433 million in transaction volume during Q1 2025, a quarterly record and a 91% increase quarter-over-quarter, driven significantly by same-chain Solana swap activity. Cumulative lifetime volume has exceeded $1.5 billion. The platform has more than 500,000 registered users, and its SDK integrations account for meaningful volume on partner platforms alongside direct platform use.

RBC Token

RBC is an ERC-20 token on Ethereum. It functions as the payment mechanism for SDK subscriptions and integration service fees, provides fee discounts on protocol swaps for holders, enables governance participation, and grants access to partner airdrop distributions. Rubic relaunched RBC tokenomics to better align token utility with protocol revenue flows and developer adoption.

Security

Rubic has been audited by MixBytes. User funds are never held on Rubic's platform at any point: all transactions are executed by calling the smart contracts of integrated providers directly, with Rubic acting as the routing and aggregation layer rather than a custodian. The protocol has received ecosystem grants from Polygon, Arbitrum, NEAR, and Stellar, indicating some level of endorsement from networks it routes on.
