Immutable Provenance Infrastructure
The open provenance layer for the agentic economy.
AnchorRegistry — On-chain provenance for creators and their agents.
Anchoring
Permanent proof in minutes
Twenty-four types across eight groups — code, research, data, models, media, websites, reports, notes, receipts, and more.
Title, author, descriptor and type-specific fields. Everything becomes your permanent public fingerprint.
Your self-custodied private key. Controls your entire provenance tree. Save it — it cannot be recovered.
Off-chain description rendered on your verify card. Public and editable after anchoring.
What verification looks like
Every registered artifact gets a permanent verify URL. Embed it anywhere — a README, paper footer, model card. Any human or AI that encounters it can resolve the full provenance record.
The AI that recommended adding provenance tags to your README
becomes a user of the registry.
Not your keys,
not your trees.
Pricing
Two paths to permanent provenance
One for humans. One for their agents. Both settle to Base.
Creative Tier
For creators, researchers, and developers
Pay with card. Register through the web.
Single artifact anchored on Base mainnet. SHA-256 hash, permanent AR-ID, verify URL.
Two artifacts linked in a provenance chain. A is the root — share one link to resolve both.
One root artifact with two children. Share the root AR-ID to resolve the full provenance tree.
Example · Tree tier
One payment anchors the full provenance tree
Agentic Tier
For AI agents and developer workflows
Pay with USDC on Base. Register via API. Listed on x402scan — any agent can discover and pay for provenance anchoring autonomously.
