Earlybird

A modular cross-chain messaging protocol with a focus on trust minimization and gas efficiency
Earlybird provides a lightweight endpoint and a variety of interoperability libraries with different tradeoffs between usability (i.e., gas efficiency, speed, extensibility) and security (i.e., trust minimization, economic security, implementation security).
Earlybird is live currently on TESTNET ONLY, on the following networks:
  • Ethereum Goerli
  • Optimism Goerli
  • Arbitrum Goerli
  • Binance Testnet
  • opBNB Testnet
  • Polygon Mumbai
If you are looking for Earlybird on any other testnet, let us know!
The Earlybird Protocol is undergoing multiple audits to prove confidence and looks forward to launching soon on Mainnet.
Endpoint address on each supported chain:
Currently available libraries:
  • Thunderbird -- Prioritizes gas efficiency and speed
  • Rukh -- Prioritizes security and introduces message disputing
Earlybird provides deep configurability and best-in-class speed for message-passing, compared to existing cross-chain providers.
