# Echo Protocol

> Bitcoin Staking & Liquidity Layer

Echo Protocol is a Bitcoin liquidity aggregation and yield protocol. It lets users deposit BTC in several forms, mint a unified BTC token on multiple chains and use it in lending and yield strategies.

Echo Protocol is a Bitcoin liquidity aggregation and yield infrastructure layer for DeFi. It accepts BTC in several native and wrapped forms and issues unified BTC tokens on other chains. The protocol is built around the Move ecosystem, with aBTC on Aptos as its main asset.

Users deposit BTC into Echo Vault and mint a chain-specific BTC token backed by the deposited assets and checked through Proof-of-Reserve feeds. Echo Lending is a money market for the protocol's BTC token and other supported assets, and Echo Strategy runs leveraged liquid staking and lending strategies at a loan-to-value ratio the user sets. Options with fixed cycles let BTC token holders earn premiums against a strike price.

The protocol's governance token is staked to earn a share of revenue from vault bridging, lending and liquid staking fees, and locked for governance. Its liquid staking token for APT earns Aptos staking yield and serves as collateral. Echo Protocol is used by Bitcoin holders, DeFi users and lending and yield protocols on Move-based chains.
