Celer Network is a layer-2 scaling platform that brings fast, secure and low-cost blockchain applications.

cBridge is at the $2,000,000,000 mark in volume moving ETH, USDT, and USDC between Ethereum mainnet, Optimism, Arbitrum, Avalanche, Boba, Fantom, BSC and Polygon.

We have the most chains and the most tokens available to bridge!  Swap instantly between chains – sometimes it is even cheaper than using the native bridge.

Our liquidity mining is live for $ETH, $USDT and $USDC, with rewards paid in $CELR
