what's Superbridge?

Superbridge is a native bridging solution designed for the Superchain ecosystem, enabling seamless transfers of ETH and ERC-20 tokens between Ethereum's mainnet and various Layer 2 rollup networks built on the OP Stack. It leverages the official bridge contracts of these rollups to ensure secure and efficient cross-chain asset movements, supporting networks such as Optimism, Arbitrum, Base, and Zora. Users can interact with a simple interface to deposit or withdraw funds, minimizing friction in DeFi workflows across interconnected chains. The protocol focuses on interoperability within the Superchain, a collection of OP Stack-based rollups aiming for unified liquidity and user experience. By integrating with tools like Hyperlane for expanded Warp Routes, Superbridge facilitates access to assets like USDC, WETH, and others from multiple sources. It prioritizes security through native contracts and provides real-time transaction tracking, making it a key infrastructure tool for developers and users navigating multi-chain environments.

Superbridge partners with Radius for Signet-to-Ethereum bridging; Radius Solver powers execution.
