Poof is a blockchain platform focused on Web3 payment and trading infrastructure, with the core goal of simplifying Crypto Assets payment processes through technological innovation. It provides a non-custodial MPC (Multi-Party Computation) encrypted wallet API, utilizing Cryptography technology to split and store encrypted keys among multiple participants, achieving Decentralization of transaction authorization while avoiding the risk of Private Key single point leakage. Developers can seamlessly integrate over 20 mainstream blockchains such as Bitcoin, Ethereum, Solana, Polkadot, and Layer 2 networks (such as Arbitrum, Polygon) through its unified API, supporting programming languages like Python, C++, and Java, significantly lowering the development threshold. This architecture is designed for Crypto Assets exchanges, payment gateways, and customization.
