Check a Window yourself
Every Window has a proof page that re-runs the on-chain check in your browser. Don't trust it — click it.
Open a proof from a position's details, from Print proofs — every settled Window, newest first — or at /proof/<marketId>. It shows the Window's verdict, a timeline (opened, open print, close print, settled) and both prints with their signers and the transaction that recorded each.
Re-verify in this browser
From the leaderboard to a trader's record to a settled Window's proof, then the closing print re-verified in the browser against the chain.

0:00 · Open the leaderboard. Records ranked from their settled calls.
0:02 · Open a record. Each row links its calls and their proofs.
0:13 · Open a proof. The verdict, the settlement transaction and both signed prints.
0:25 · Re-verify the close. The browser reads the recording transaction and asks the verifier contract again.
0:27 · Verified. The close passes twice: its record transaction and the archive. This open is the previous Window's close.
Re-verify, in the page head, runs every check at once:
Read the record
Your browser reads the print's record transaction straight from Tempo's RPC.
Take the packages out
It decodes the RedStone signed packages from that transaction's calldata.
Ask the verifier
It calls verifyPrint on the same on-chain verifier the engine used, with eth_call, and compares the price it returns with what the engine recorded.
The same press also runs the verifier on ops' archive — RedStone's own packages for every boundary instant, kept apart from any transaction. For a Window that never got a print, it shows what the archive held and why the verifier refused it — too few signers at that instant, for example.
Each check is a row under Check it yourself: matches, differs, or can't check. Nothing in the record check comes from Mitoshi's servers.
What it does not prove
A proof shows that a recorded print is the signed price the verifier accepts. It does not say the house quoted fairly, or that a position was yours: those are on the record and in your own receipts.
Prints and settlement
A Window settles on two signed numbers, its opening print and its closing print. Who records them, who settles, and what a void pays.
The Trading Balance
A vault you own on Tempo. A capped key taps from it, a keeper runs your exits from it, a strategy trades in it — and only you withdraw.
