Verify a receipt
Paste a signed action receipt and verify its Ed25519 signature, payload hash, and bound fields entirely in your browser. Nothing you paste leaves the page.
Open the verifier →Receipt signing keys
The public keys GateCore signs receipts with, served unauthenticated so anyone can verify independently. Rotation adds keys; old receipts stay verifiable.
