Multi-chain USDC payments archived to 0G, letting AI agents verify payment proofs before unlocking paid access, answers, APIs, or services.
This demo shows Hash PayLink’s 0G-powered agentic payment loop: a user pays through Hash PayLink, the payment is archived to 0G Storage and anchored on 0G Mainnet, then an AI agent verifies the 0G proof before unlocking a paid response.
Flow: PayLink payment -> 0G archive -> /api/agent-verify -> paid AI access unlocked.
During the hackathon, we implemented the 0G payment proof layer for Hash PayLink.
Key progress:
- Integrated 0G Storage for permanent payment record archiving.
- Deployed PayLinkArchive on 0G Mainnet.
- Added dashboard 0G proof badges for archived payments.
- Built /api/agent-verify for trustless payment verification.
- Built /api/agent-ask for payment-gated AI responses.
- Extended the Telegram agent flow so paid AI access can verify payment before responding.
- Updated documentation, README, and demo flow for judges.
The result is a working agentic payment loop: PayLink payment -> 0G archive -> agent verifies -> AI access unlocked.
Hash PayLink is currently bootstrapped and not actively fundraising. We are focused on shipping the 0G-powered agentic payment layer, growing real usage, and preparing for ecosystem grants and strategic partnerships.
