Band a trade. Watch the wire. Verify the answer yourself.

Everything on the left happens in this browser tab. The values you type are banded and hashed here; only commitments are sent. The right pane shows the exact bytes that will cross the wire, and then scans them for the numbers you typed — so the central claim is something you check, not something we assert.

① Local — never leaves this tab

The shared secret is the key you and your counterparty agreed for this corridor. It derives the per-shipment salt. It is never transmitted, and the operator has no way to obtain it.

0 = the legs must land in the same band

Or load a batch from the on-prem bander

The bander is a single binary that runs next to your trade-finance extract: raw values in, salted commitments out, no network. Its output already carries a pinned bander identity, so the operator can report whether both parties ran a binary the other recognises.

② The wire — exactly what leaves

What leaves this tab, drawn: each leg’s sealed commitments beside the figures that stayed behind. The exact bytes handed to fetch are one click away — fingerprinted and copyable, so you can hash them yourself.
