Optimism Bridge is your gateway to the Optimism Superchain — a fast, low-cost, and decentralized Layer 2 bridge platform built on the OP Stack. Discover our mission, technology, and the team behind Optimism Bridge.
Optimism Bridge exists to make cross-chain bridging accessible, transparent, and secure for everyone in the Ethereum ecosystem. We believe that the future of decentralized finance is multichain, and the Optimism Superchain is leading the way.
By connecting Ethereum mainnet with OP Mainnet and other OP Stack chains, Optimism Bridge reduces transaction costs by up to 10x while maintaining the full security guarantees of Ethereum. Our mission is to remove barriers to entry for users who want to participate in the growing Optimism ecosystem.
Transfer ETH, USDC, DAI, and other tokens between Ethereum and OP Mainnet in minutes, not hours.
Optimistic rollup technology compresses transaction data, slashing costs to fractions of a cent.
All bridge transactions are secured by Ethereum's consensus and Optimism's fault-proof system.
Bridge ETH and a wide range of ERC-20 tokens including USDC, DAI, USDT, WBTC and more.
Optimism Bridge embraces ecosystem-driven bridging, leaning on trusted third-party providers for maximum decentralization.
Built natively for the OP Stack, ensuring compatibility with all current and future Superchain networks.
Optimism Bridge is powered by the OP Stack — an open-source, modular blockchain framework developed by Optimism. The OP Stack uses optimistic rollup technology to batch transactions off-chain and post compressed proofs to Ethereum mainnet, achieving dramatic scalability without sacrificing security.
Withdrawals from OP Mainnet to Ethereum go through a challenge period (typically 7 days) to allow for fraud proofs, ensuring the integrity of every bridged asset. For faster withdrawals, third-party liquidity providers integrated into Optimism Bridge offer near-instant exits.
The Superchain vision unites multiple OP Stack chains — including OP Mainnet, Base, Zora, Mode, and others — under a shared security model. Optimism Bridge supports bridging across all Superchain-compatible networks, making it the most versatile gateway in the Optimism ecosystem.
Optimism Bridge supports a growing list of tokens for bridging between Ethereum and OP Stack chains. Key supported assets include:
Native Ether bridging between Ethereum L1 and OP Mainnet L2 with full security guarantees.
USD Coin bridging with native Circle support on OP Mainnet for stable value transfers.
MakerDAO's decentralized stablecoin, fully supported on the Optimism Superchain.
Hundreds of ERC-20 tokens are bridgeable through the standard Optimism token bridge interface.
Optimism Bridge is supported by a dedicated team of blockchain engineers, protocol researchers, and ecosystem builders committed to growing the Optimism Superchain.

Optimism Bridge is not just a bridge — it's the official gateway to the Optimism Superchain. Unlike third-party bridges, Optimism Bridge uses the canonical Optimism bridge contracts, which are directly secured by Ethereum's consensus mechanism. This means your assets are never at risk from custodial failures or third-party smart contract exploits when using the native bridge path.
We also aggregate trusted ecosystem bridges like Superbridge and Brid.gg, giving users the flexibility to choose the experience that best fits their needs — whether they prioritize speed, cost, or maximum decentralization.
