- Ethereum ERC-8004 draft opens in a new tab
Supports: ERC-8004 proposes portable agent identity, reputation, and validation registries, while explicitly treating payments as outside its scope and remaining a draft.
- Coinbase Developer Platform: x402 overview opens in a new tab
Supports: x402 is a payment mechanism for paid APIs and digital services in the request flow; it does not solve counterparty trust, agent authority, or content licensing on its own.
- NIST AI Risk Management Framework 1.0 opens in a new tab
Supports: AI systems need governance, measurement, and managed risk; identity or payment primitives do not remove the need for accountable oversight.
