Celer Network

Celer Network is a blockchain interoperability protocol that enables seamless cross-chain experiences for dApps, assets, and users. Its flagship cBridge is a decentralized cross-chain asset bridge supporting 40+ blockchains with over $14B in cumulative transfer volume, and Celer IM (Inter-chain Messaging) is a framework for building multi-blockchain applications with efficient liquidity, coherent logic, and shared state. For developers, the cBridge gateway exposes a public gRPC-Web / REST API (sgn.gateway.v1.Web) for discovering supported chains and tokens, estimating cross-chain transfer fees, tracking transfer status, and withdrawing liquidity. Celer was surfaced as a portfolio company of Pantera Capital.
