The most common errors leading to invalid payments in cryptocurrency

The most common mistakes that senders make when sending transactions:

• Invalid wallet address (e.g. sender a mistake when entering the payment gateway wallet address).
• Invalid amount (e.g. 14.39 USDT real amount in blockchain instead of 15.39 USDT in invoice generated by payment gate) - you can check the actual transaction amount (excluding withdrawal fees, charged by the sender's wallet) in blockchain explorer.
• Invalid token (e.g. the sender sent TRON or TUSD 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).
• 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). In this case, please refer to the article.
• You forgot to indicate the Destination Tag / Memo when sending TON to Volet.com. In this case, Volet.com will require you to provide them: "A screencast showing him or her logging into the system from which this transaction was made. Before logging in, it is necessary to make sure the screencast is running, and the full screen is visible, including the URL field. In addition, we ask to show the hash of the transaction within the system and click on it."
• Payment gateway Volet.com may place a transaction under review by Volet.com Compliance Department to prevent fraud and comply with Anti-Money Laundering (AML) regulations if the coins sent to Volet.com wallet are dirty (have a high risk score). In this case, Volet.com will require you "To proceed with the review, we kindly request that you ask the clients who sent them to contact us directly at support[at]volet.com to provide additional information regarding the payment required for further approval." If you have concerns that the funds you want to send are dirty, we recommend checking your wallet in blockchain analytics risk scoring services (for example, AMLbot, HAPI Labs, Crystal, Chainalysis, Ellipltic).

Note: Invalid transactions (invalid wallet address, token, token standard, amount or blockchain) 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 https://blockchair.com or https://tokenview.io 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).
