The most common errors leading to invalid payments in cryptocurrency

The most common mistakes that senders make when sending transactions:

  • Invalid coin (e.g. the sender sent USDC or TUSD or TRON instead of USDT);
  • Invalid token standard / blockchain (e.g. ERC-20 instead of BEP-20, or the token standard is correct, for example ERC-20, but it is sent in the Avalanche network, not Ethereum);
  • Invalid amount (e.g. 14.39 USDT real amount in blockchain instead of 15.39 USDT in invoice generated by payment gate);
  • Invalid wallet address (e.g. sender a mistake when entering the payment gateway wallet address);
  • Sending a payment to the network with a delay or with insufficient network fee (the transaction was included in the block after the payment gateway timeframe expired).


Note: Incorrect transactions cannot be processed by payment gateway and this will lead to loss of funds!

If you transfer cryptocurrency directly from an exchange (e.g. Binance etc.) or some custodial wallets that charge their customers with additional hidden fees when sending transactions, please keep in mind that the real amount sent may be less by that fees. In addition, some exchanges send aggregate transactions with a delay or with a commission insufficient for the transaction to be included by miners in the current block and not remain in the mempool awaiting subsequent blocks - this may cause the temporary payment gateway address for payment of the issued their invoice will expire during this time.

Please note that payments are sent not to our wallet, but to the temporary technical address of the payment gateway. If funds are not transferred to us, we will not be able to credit them to your account.

You can check transaction details of the payment sent by your exchange or wallet in the blockchain explorer (for example, you can use or blockchain explorer).

We recommend using only non-custodial wallets, where you can independently manage the real transaction amount, sending speed and network fees (e.g. Trust wallet for USDT or electrum for bitcoin).
