Azeth

Machines that transact need what people with bank accounts take for granted: an account, a name that others can check, a record of behavior, and a way to pay. Azeth builds that base layer as three composable pieces - non-custodial smart accounts following ERC-4337, on-chain identity with payment-gated reputation following ERC-8004, and machine-to-machine USDC payments over x402. Reputation is gated by payment on purpose: an opinion about an agent counts when the reviewer actually paid for the work.

The system runs today on Ethereum Sepolia and Base Sepolia, deployed to identical CREATE2 addresses on both networks. Developers reach it three ways: an MCP server for agents, a TypeScript SDK (@azeth/sdk on npm), and a CLI. It is testnet alpha in the plain sense of those words - not for production use, not for real assets, and with no external security audits yet. The registry is public, and every contract address can be checked on a block explorer.
