Every day, 3+ Million DeFi users waste hours and hundreds of dollars on fees migrating between blockchains, switching between DEXs, and using bridges. The Rubic Relay Widget has the full functionality of Rubic.exchange, and enables users to buy and sell tokens on any website. This means that users of any project can buy that project’s tokens without having to leave their website. Integration is both simple and fast.


Rubic Multi-Chain Swap Protocol, which allows users to swap more than 15,000 assets between 11 major blockchains Ethereum, Polygon, BNB Smart Chain, Avalanche, Moonriver, Fantom, Harmony, Solana, Arbitrum, Aurora, and NEAR; in one place, with a simple and intuitive UI. On Ramper is a fiat on-ramp solution aggregator. Its integration enabled our users to buy cryptocurrency directly with their fiat currency. Users may always choose either KYC-required or non-KYC options. Now, users can choose between 45 different fiat currencies to purchase up to 124 cryptocurrencies.

Business Model

Rubic charge a 0.3% commission for all Multi-Chain Swaps. 0.2% of this fee goes to Staking and Liquidity Providing, and 0.1% of it goes to Rubic. Rubic also charges up to 0,3% for On-Chain swaps using your Widget on reffered projects’ websites. The protocol layer is a set of smart contracts on the blockchain that are used to manage assets, verify signatures of validators/relayers and reach consensus between validators; since a transaction is considered valid only if the required threshold of minimum validators confirmations is reached.

Multi-Chain Swaps

Rubic protocol offers easy trading for more than 15,000+ assets across Polygon, BNB Smart Chain, Ethereum, Avalanche, Moon River, Fantom, Solana, Harmony, Arbitrum, Aurora and NEAR networks, using our custom and unique Multi-Chain Protocol. Utilizing liquidity pools and your own smart contracts, provides an extremely easy-to-use multi-chain solution to all traders. When the relayer collects two of three signatures from the Validators, it initiates a transaction on Blockchain 2 by calling the function of the Multi-Сhain Routing smart contract in Blockchain 2 — sending tokens to the user.

Validators and Relayers

Validator is a verification node whose purpose is to track events on your Multi-Chain Routing contract, and report them to the Relayer. The message to the Relayer contains transaction data (information about the completed transaction in the source network and the parameters with which to send the transaction to the target network). The validator signs this data with its private key. Relayer is a node whose purpose is to collect the necessary number of messages from validators, and to send the transaction.

Why is Rubic using more than one Relayer?

They have created several extra relayers in order to maintain your continuous improvements and growth of Multi-Сhain Routing feature. Validators will scan the final blockchain, for the event of sending tokens from a smart contract using a unique hash (the event is generated when the function of the swap contract is called — sending tokens to the user). If no tokens are sent after a specified period of time, Validators send a message to another Relayer. The smart contract will reject the duplicated transactions with the same unique hash from the Relayers if they were already sent.
