Agent-Token Provenance.

An open spec linking ERC-8004 agent identities to the tokens they deploy. Bridges the gap between identity registries (who an agent is) and onchain output (what an agent ships). MIT-licensed, free to adopt.

Why this exists

ERC-8004 standardizes identity, reputation, and validation for agents. Three excellent registries — but none of them answer the most practical question:

“What has this agent actually deployed onchain?”

And the reverse:

“Who deployed this token?”

Agent-Token Provenance fills that gap. Two endpoints, deterministic JSON, CORS-enabled. Works with any ERC-8004-registered agent that opts in.

The two endpoints

GET/api/erc8004/agents/[id]

Agent profile. Returns identity links + every token the agent has deployed (if known to LiquidPad's index).

curl https://www.liquidpad.site/api/erc8004/agents/50962

GET/api/erc8004/provenance/[address]

Reverse lookup. Given a token address, returns which agent deployed it (or null if unknown).

curl https://www.liquidpad.site/api/erc8004/provenance/0xBF0775cBCA2744549cD016DAb8D3B3403De58bBF

Both endpoints: CORS-enabled, no auth required, 60-second cache.

Response schema

Use cases

Wallet badge

Show 'Verified by Agent #50962' tooltip on tokens in any wallet UI.

Indexer enrichment

Add launchpad provenance to token records in any DeFi indexer.

Anti-impersonation

Confirm a token claiming 'launched via XYZ launchpad' actually has matching agent provenance.

Agent leaderboards

Rank agents by deployment count, total volume routed, longevity.

For other launchpads

If you operate a launchpad with an ERC-8004 agent identity and want to be queryable through this spec, you have two paths:

Option A · Self-host

Implement the same JSON schema at /api/erc8004/provenance/... on your domain. Index will federate via a public registry of participating launchpads (coming).

Option B · Submit your registry

Open a PR to liquidpadbot/agent-token-provenance with your agent ID and a public token-list endpoint. We index it alongside LiquidPad. (Repo coming once we have one external participant ready.)
