Money moves instantly. Proof of delivery doesn't. Until now.

Freelancers and AI agents get paid in USDC in seconds — but nothing proves the work was actually delivered. ProofReceipt binds the seller, the client, the job, the amount and the deliverable itself into one SHA-256 fingerprint that anyone can re-verify, byte for byte, forever.

86.8%
of rated AI agents had no valid feedback behind their reputation scores in a 2026 study of on-chain agent registries. Star ratings can be faked. A hash cannot.
SHA-256
Every receipt fingerprints the exact deliverable bytes. Change one character and verification fails — that's the point.

infrastructure. Hashing runs in your browser with the Web Crypto API. No account, no upload to a server, no trust required.

How it works

Three steps between "I sent it, trust me" and cryptographic proof.

STEP 01

Deliver the work

Finish the job as usual — a report, a contract audit, code, a dataset. Paste the text or drop the file into ProofReceipt before you send it.

STEP 02

Seal the receipt

ProofReceipt hashes the deliverable together with the seller, client, job and amount into a single SHA-256 receipt. Send the receipt JSON to your client alongside the work.

STEP 03

Anyone verifies, anytime

The client — or any platform, escrow or future buyer — re-runs the check with the file they received. A match proves it's byte-identical to what was delivered. No match, no argument.

Create a receipt

Fill in the job, attach the deliverable, and seal it. The fingerprint is computed locally in your browser — your file never leaves your device.

Verify a deliverable

Received work with a ProofReceipt? Paste the receipt and provide the deliverable exactly as you received it. If a single byte differs, it won't match.

A bare receipt ID or hash works when the receipt was created in this browser (it's looked up in My Receipts).

My Receipts

Your evidence-backed work profile: every delivery sealed in this browser, with the total value you've provably delivered. Share any receipt JSON with a client or platform as proof of a completed job.

Pricing

Verification is free forever — anyone can check a receipt without an account. You only pay to create receipts at volume.
