Orbiter Finance is a decentralized bridge that supports cross-rollup transfers between Ethereum and other layer-2 blockchains such as zkSync and Arbitrum. Users can move ETH, USDC, USDT, and DAI between those supported networks.

It is secured by a series of smart contracts that involves two roles: Sender and Maker. The Maker provides liquidity for the transfer initiated by the Sender. If the Maker does not carry out their role, the Sender can initiate an arbitration request to the contract with the Maker’s margin and receive compensation for any excess losses.
