Bitcoin Mix guarantee letter: what to verify before sending BTC

A guarantee letter records the terms of an order and links them to the issued deposit address. Save it before sending BTC and do not edit its contents.

Bitcoin Mix guarantee letter: what to verify before sending BTC

What the letter contains

The letter lists the deposit address, payout addresses, amount distribution, service fee, selected delay, payment window and order limits.

The service address used for the digital signature appears at the end of the message. This lets the user independently verify that the letter has not been modified.

How to verify it

Download the letter immediately after creating the order. Enter the service address, the complete message between the letter boundaries and the digital signature in a compatible verification tool.

Copy the text exactly. Changing a character, space, address or amount invalidates the signature. You can use verifybitcoinmessage.com for the check.

  • Bitcoin Address — the service address stated in the letter.
  • Message — the letter text without the START and END labels.
  • Signature — the line between the digital signature boundaries.

What to compare manually

Even when the signature is valid, compare every payout address, distribution percentage, fee and delay with the values entered in the form.

Do not send BTC if any address or condition differs. Create a new order and repeat the check.
