Payments from exchanges and custodial wallets
To avoid complications please do NOT send from an exchange or custodial wallet. Exchanges typically charge a withdrawal fee and deduct it from the amount you are withdrawing. While we discourage you from sending from a custodial wallet, if you do, you will be required to account for the exchange's withdrawal fee and we are not responsible for any delays in processing payments or lost cryptocurrency.
For example if you send us 1 BTC and the exchange's withdrawal fee is 0.00001 BTC then you will only have sent us 0.99999 BTC and we won't be able to complete your purchase until you pay the full amount. Fortunately, you can top-up the amount to the same public receiving address but this will cost you even more in transaction and withdrawal fees.
We reserve the right to refuse or cancel your order at any time if your payment is made from a wallet which is considered custodial. Custodial wallets are wallets in which the user is not in control of their own funds; the user does not hold the private keys.
