The Agent Trust Ledger · IronBridge × Net Protocol

Proof that an AI agent actually got what it paid for.

An agent pays 10 cents to run a search. This page gives you tamper-proof evidence it got a real answer — evidence anyone can re-check in a browser, no login, no key. Payment rails stop at “paid”; IronBridge also proves what the payment bought. Net Protocol is the message store — it records who said what; IronBridge proves it.

Paste a receipt id. Recompute the binding.

A receipt proves: which wallet paid (payer), what it called (tool), the on-chain payment (txHash), and the exact result (data_sha256) — bound together and chained. Try a real one:

Why this is the layer no one else has
x402
moves the money. It settles a payment — but never proves the payer got a real, specific result.
MCP
connects the tools. It routes a call — but keeps no keyless, public proof of what was returned.
Net
stores the message. Permissionless reputation — but it stores a genuine message and a spoofed one identically; it can’t prove the asserted sender actually paid or that the result is real.
IB
proves the call. The one invariant Net can’t enforce — msg.sender == receipt.payer, result recomputed and re-walked against the public chain. A spoof can’t bind; an honest call does. That verified receipt then feeds Net’s on-chain reputation, so honest paid agents accrue standing anyone re-verifies.
Truth in labeling. The rail is open; the traction isn’t claimed. Today the ledger’s calls are operator self-tests — no external agent has posted a paid receipt yet. The receipt→Net reputation post is built and proven against a genuine and a spoofed message, arming pending. What you verify above is exactly what the rail did — nothing here is faked.

Keyless. Trustless. Re-walkable. No key of ours signs a receipt — you recompute the proof and confirm it yourself.
