Summary
ERC-8194: Payment-Gated Transaction Relay (PGTR) defines a relay primitive where an on-chain payment receipt serves as authorization instead of a cryptographic signature. Any token-holding actor — human, AI agent, or IoT device — can authorize on-chain actions without managing a private key.
Motivation
Existing meta-transaction standards (ERC-2771, ERC-4337) require principals to hold private keys. PGTR solves key abstraction: authorization is "I paid", not "I signed". This enables lightweight autonomous agents, human users preferring payment-only UX, and micropayment-gated services to participate in on-chain protocols on equal footing.
