Almost all delayed deposits trace back to something that happened before the transaction reached Flush. Here are the main causes and how to avoid them.
Low network fees
When you send crypto, you pay a fee to the blockchain network. During busy periods, transactions with low fees get queued behind higher-fee transactions and can take hours to confirm. Most wallets offer fee options and standard or fast is usually sufficient to avoid delays.
Network congestion
Ethereum can become congested during high-activity periods, slowing down all transactions regardless of fee. If you need a fast deposit, TRC-20 USDT or LTC are generally more reliable during peak times.
Wrong network selected
Sending USDT via ERC-20 to a TRC-20 address means the funds will not arrive. Always confirm the network matches in both your wallet and the Flush cashier before sending.
Deposit below the minimum
Transactions below the minimum deposit threshold for a currency are not automatically credited. Check the minimum shown in the cashier before sending.
Sending to the wrong address
Copy the deposit address directly from the Flush cashier every time. Confirm the first and last few characters after pasting. Never type an address manually.
If your deposit is already delayed
Look up your TXID on a blockchain explorer to check its confirmation status. If it shows as fully confirmed but has not appeared at Flush, contact live chat with your TXID.
