Based on MPC (Multi-Party Computation), HashKey Me is a decentralized identity wallet supporting multiple blockchains. With email addresses as unique identities, users can generate accounts compatible with a number of major blockchain ecosystems, including Cosmos, Bitcoin, Ethereum, Polkadot, Polygon, Avalanche, Arbitrum, and Conflux. While safeguarding digital assets in a decentralized manner, the solution also lowers barriers to access, for it does not require managing memorics and private keys.
