t2000

t2000 is an open-source finance stack for AI agents on Sui, split into four packages: an agent wallet with a CLI and MCP server that sends and receives USDC and USDsui and swaps through Cetus routing; an x402 payment layer that lets agents pay per call in USDC with no signup or API keys; an onchain agent identity registry recording name, handle and owner, with services and escrow contracts attached; and an underlying TypeScript SDK.

It removes the engineering friction of giving an agent a wallet: gas is handled through sponsorship and auto top-up, multi-step operations compile into a single atomic transaction that reverts entirely on failure, defaults cap spending at 25 dollars per transaction and 100 per day, and transactions are simulated first. Keys stay on the agent's machine. Escrow settlement charges 5 percent, the code is MIT licensed and published to package registries, and it plugs into Claude, Cursor and Windsurf.
