Description
HOT Protocol implements decentralized Chain Signature infrastructure through MPC validator networks, enabling programmable wallets to execute transactions across multiple blockchains. The system distributes private key segments across independent validator nodes using Multi-Party Computation, allowing secure transaction signing without single-point vulnerabilities. Protocol features include replaceable seed phrases, programmable 2FA authorization, cross-chain gas abstraction through HOT Relay, and smart contract interfaces for custom access control. Validator nodes operate with end-to-end encrypted communication and participate in transaction signing through collateralized HOT token staking.
