# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.allstake.org/technical-architecture/chain-abstracted-avs.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
