The proliferation of Web3 technologies, particularly decentralized finance (DeFi) and non-fungible tokens (NFTs), has brought with it a critical challenge: secure and reliable management of private keys for blockchain accounts. Unlike traditional banking systems where institutions can reset passwords or recover lost accounts, the decentralized nature of blockchain means losing a private key often results in permanent loss of access to digital assets. This talk, presented by Panagiotis Chatzigiannis from Visa Research, introduces a novel **composability analysis framework** designed to formally assess the security of combined Web3 wallet recovery mechanisms.
