SUI, developed by Mysten Labs, introduced the Seal MPC prototype on its testnet, a programmable wallet system that allows AI agents to propose transactions securely without ever accessing full private keys. The system uses multi-party computation and decentralized key management to split cryptographic authority, enforcing spending rules via Move smart contracts. This innovation aims to enable safe AI-driven payments and agentic commerce, with a mainnet launch expected around June 18, 2026. For investors, this development could increase network use and demand for the SUI token, though the product remains in testing and requires further security validation before real-world use.
