# Chain-Abstracted AVS

Different from other (re)staking protocols, AVS developers on Allstake can build their infrastructures with multi-chain features from day one. 

As illustrated by [EastBlue](https://eastblue.io/), which is built with Chain Abstraction on NEAR, developers can build AVSs that are available for multi-chains, including Bitcoin, with minimal efforts on client chains. For example, you can build a cross-chain oracles for Ethereum, Solana, NEAR and Cosmos by synchronizing price feed data from your oracle AVS contracts on NEAR to client oracle contracts on Ethereum, Solana and Cosmos chains.
