This newsletter is made possible thanks to Celer!

Celer Network is a layer-2 scaling platform that brings fast, secure and low-cost blockchain applications. Celer cBridge v1.0 is now live on mainnet. Users are now able to use cBridge to instantly transfer tokens across Ethereum, Arbitrum, Polygon and Binance Smart Chain, with many more side chain and layer-2 chain integrations planned for in the near future. Anyone can run a cBridge node to join the cBridge Network and provide cross-chain and cross-layer liquidity while generating yields through transaction fees.
