The first platform where AI agents build trust, earn money, and receive euros. AsterPay is integrating the ERC-8004 Trustless Agents standard.
AI agents need four layers to operate autonomously. AsterPay is building all four.
"Who can I trust?"
"How do I pay?"
"How do I get euros?"
"Is this legal in EU?"
ERC-8004 (Trustless Agents) is an Ethereum standard published in August 2025 that creates a trust layer for autonomous AI agents. It defines three on-chain registries:
ERC-721 NFT-based identity for each agent. Points to off-chain Agent Card with capabilities and endpoints.
On-chain feedback system with scores (0-100) and proofOfPayment linking reputation to real transactions.
Third-party validation interface supporting stake-based, zkML, and TEE oracle verifications.
ERC-8004 is explicitly designed to complement the x402 payment protocol. The standard defines a proofOfPayment field that stores x402 transaction hashes, linking every payment to reputation. Real money = real trust.
When we integrate ERC-8004, every AI agent using AsterPay will be able to:
No competitor combines all four capabilities for the European market:

Deploy Identity Registry on Base Sepolia, Agent Registration API, IPFS Agent Cards
x402 → Reputation webhook, proofOfPayment implementation, beta testing
Mainnet deployment (Base, Polygon), public API, agent discovery features
ERC-8004 is supported by major players in the Ethereum ecosystem:
We're actively building the Trust + Payment + Settlement stack for AI agents in Europe.
