Coinbase has launched a new version of its cloud product, called "Coinbase Wallet as a Service," which uses multi-party computation (MPC) and is now live on the Ethereum mainnet. The Web3 wallet solution allows end-users to explore without managing complicated recovery phrases, instead using just a username and password. The product enables various Web3 interactions through APIs and SDKs, including Coinbase's Pay SDK for purchasing digital assets and an API for integrating crypto-based payments. MPC solutions typically split the private key behind a wallet into several shards that can be split between multiple owners for safekeeping of their underlying digital assets.
