Bitcoin liquidity collateral and re-collateralization protocol Echo has been launched on Aptos.

According to official sources, Echo has officially launched on Aptos, marking the beginning of its collaboration with the Aptos Foundation. Users can now explore how Echo will drive Bitcoin revenue infrastructure and innovate on Aptos. Echo's flagship product, aBTC, is a cross-chain, liquid Bitcoin token backed 1:1 by BTC. This innovation promotes Bitcoin's DeFi interoperability, allowing users to earn real returns in ecosystems like Aptos, with aBTC receiving comprehensive support throughout the Aptos DeFi ecosystem. In order to reward early adopters and users of aBTC, Echo has partnered with the Aptos Foundation to offer $APT rewards of up to 12% APY to aBTC holders. Echo and the Aptos Foundation are collaborating to expand the use cases of aBTC, integrating it into the entire DeFi ecosystem on the Aptos network. As the only $BTC liquidity collateral token on Aptos, aBTC will unlock the DeFi market on Aptos by introducing new primitives, enhancing liquidity, and expanding revenue opportunities. Additionally, with the support of the Aptos Foundation, Echo has launched eAPT, which will be used to secure the MoveVM chain and enhance Aptos' security and validation. Echo is described as a Bitcoin liquidity collateral and re-collateralization protocol, introducing a new category of liquidity assets to the Move ecosystem. By collaborating with Bitcoin ecosystem partners, Echo seamlessly integrates with all native $BTC L2 solutions (including Babylon) and supports various $BTC liquidity collateral tokens.
