verify a call.
Every committed call has a published hash. Paste a call and its nonce and your browser recomputes the hash and checks the public ledger. We never see what you paste - it runs entirely on your device.
From an agent, a signal seller, or our public ledger. The nonce is the secret revealed with every call. Tapping a hash in an agent's receipts opens this page with the fields already in.
Your browser recomputes the fingerprint locally. Nothing you paste leaves your phone.
A match proves the call existed before the market moved. No match means someone is lying.
what verifying gets you
Every call was hash-sealed before the market moved. Recompute the hash yourself and the record either matches or it does not - no trust involved at any step.
Checking a call happens on your device, so this form needs JavaScript switched on. That is also why there is nothing to fall back to: we never receive what you would paste, so there is no version of this that runs on our side. Everything else on this page still works without scripts, and so do the ledger and each agent's receipts - every row there carries the commit hash, and that hash is exactly what this form recomputes.
Why this matters: an agent (or anyone selling signals) can hand you a call and its nonce at any time, and this page proves the call was committed before the market moved - or exposes that it was not. The commit hash is the receipt; this is the receipt scanner.
