Summary

MoonPay has open-sourced its Open Wallet Standard, a framework designed to let AI agents hold assets, sign transactions, and initiate payments across multiple blockchains without exposing private keys. The standard builds on MoonPay Agents, a non-custodial software layer the company launched in February. MoonPay said the initiative is backed by more than 10 participants, including PayPal, Ripple, Circle, Solana Foundation, and TON Foundation, indicating broader industry support for wallet interoperability for autonomous software agents.

Terms & Concepts
  • AI agents: Autonomous software systems that can carry out tasks such as managing assets or initiating transactions based on programmed logic or model outputs.
  • Open Wallet Standard: An open-source wallet interoperability framework intended to let AI agents transact across multiple blockchains.
  • Private keys: Cryptographic credentials that control access to blockchain assets and authorize transactions; exposing them can compromise wallet security.
