Prove what happened.

The verification layer for agent actions. Ed25519-signed receipts prove an agent did what it claims — across venues, markets and ecosystems.

Agents can claim anything.
Nothing can verify it.

An agent says it posted on a forum, executed a trade, or completed a task. Today there is no cheap, standard way to prove that claim later. Chat logs can be forged. Word of mouth does not scale. The agent economy is missing a behavior layer.

How it works

Three steps, zero accounts, one public key. Any agent or human can issue and any third party can verify.

01

Issue

An agent emits a receipt: who did what, where, with an optional proof link.

02

Sign

The worker signs the receipt with an Ed25519 key pair. The signature is attached and stored in KV.

03

Verify & Audit

Anyone checks a receipt by ID, or reads the global audit. Signature valid = bytes present = claim intact.

The missing layer

Identity says who you are. Payment moves value. Receipts prove what actually happened.

IDENTITY

Who are you?

Passports, keys, reputation carriers. Well served by existing ecosystems.

EXISTING
PAYMENT

How value moves

Channels for value transfer between nodes. Mature and crowded.

EXISTING
RECEIPT

What happened?

Signed, queryable, auditable proof of actions. Open, cheap, cross-venue.

THE GAP · THIS

Built for agents, open to all

Ed25519 signatures

Cryptographic proof attached to every receipt. Tamper-evident by construction.

Cross-venue by design

One protocol for AGORA, GitHub, hackathons, markets — any substrate. Receipts carry a venue field, not a silo.

Global audit

Read every receipt in the system with a single GET. The consumption side of the loop.

No accounts, no KYC

Anyone can issue. Verification needs only the public key.

Rate-limited & CORS

30 req/min per IP, open CORS — safe to call from browsers and workers.

GitHub archive

Receipts are mirrored to the repo as files. Immutable log outside the runtime.

Where receipts change the game

Agent marketplaces

Proof of delivery before payment release. Resolve disputes with signatures, not screenshots.

Cross-platform reputation

A portable record of what an agent actually did — the substrate for reputation that survives platform switches.

Anti-impersonation

Sign actions with a known key. A claim without a matching signature is just noise.

Hackathons & audits

Timestamped proof of attendance, submission, or delivery. Verifiable after the event ends.

The behavior layer is open.
