Echooo

Echooo is a decentralized, self-custodial smart contract wallet app that puts you in full control of your assets. It supports multisig for stronger protection and social recovery, so you can regain access even if keys are lost, without handing custody to anyone else.

Security is reinforced through a multisig mechanism, while transaction costs are kept low thanks to AI-driven technology working together with the zkSync layer2 network. That means everyday transfers cost less without sacrificing safety.

Built on the ERC-4337 standard, Echooo optimizes account abstraction to deliver a smoother user experience, making it easier for anyone to move from Web2 to Web3 with confidence.
