Orbiter Finance is a decentralized, cross-Layer-2 bridge protocol that enables instant and low-cost asset transfers between the Ethereum mainnet and multiple Layer-2 rollups. The platform also uses ZK-proofs for security and privacy. Since its 2021 launch, the protocol has processed millions of transactions totaling more than $7.8 billion and serves a robust user base of over 3 million users.
Unlike many bridges prone to delays or centralization, Orbiter achieves cross-rollup transfers in seconds with gas fees far lower than other platforms. Meanwhile, it supports 50+ tokens across 19+ chains — including Ethereum, Arbitrum, Polygon, Ronin, Sui, Optimism, zkSync, Base, Linea, Solana, and more.
Under the hood, Orbiter uses a decentralized Maker system. This structure involves independent liquidity providers (Makers) running nodes to facilitate transfers and earn fees, which are now secured by zk-SPV proofs and arbitration mechanisms. The protocol is well-funded by OKX Ventures, Tiger Global, Matrixport, StarkWare, and even Vitalik Buterin, underscoring its strong institutional support.
Orbiter is evolving into an omni-chain rollup infrastructure that has plans for a zk-powered rollup that aims to unify multi-chain transfers under one protocol.
