Ethereum Foundation launches zkAPI for anonymous AI service payments
- —Launched on 1 October 2026 on Ethereum mainnet in partnership with the Open Anonymity Project
- —Deposits are accepted in ETH and USDC, with balances stored as private notes in a vault contract
- —zkAPI does not hide prompt content or IP addresses, and the code is labelled experimental
- —The design is based on a proposal by Vitalik Buterin and Davide Crapis published on 11 February 2026
Why it matters: The project addresses a privacy gap in AI service payments and expands Ethereum's role as a settlement layer for AI agents.
