Letter of Guarantee

Fixed-quote order — mixer and Zcash deposits

The rate and the amounts lock when the order is created, so the letter states them at once: direction, locked rate, exact deposit amount, payout amount, service fee, deposit address, recipient and deadline. There is one version of this letter — re-downloading it returns the identical signed text.

Floating-rate order — every cross-asset direction

The rate is not fixed when the order is created, so the letter is issued in two stages.

1. 1

   Before the lock — the pricing contract

   Direction, the accepted deposit range, the service fee, the rule that fixes the rate (the live market snapshot at the moment your deposit reaches the required confirmations), what happens below the minimum and above the maximum, deposit address, recipient and deadline. Any amount inside the range is covered: the letter guarantees how your deposit will be priced, not a number.

2. 2

   After the lock — the locked figures

   Once the deposit is confirmed the letter is re-issued with the locked rate, the received and payout amounts and the exact lock time, on top of the same contract. Download it again at this point — the second version is the one that states your final numbers.

Re-downloading at the same stage always returns byte-identical text with the same signature; only the lock changes the letter. Keep both versions of a floating-rate letter — each verifies on its own.
