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: 
​Testnet​
​Mainnet (coming soon)
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.
