Cryptocurrency transactions are a bit tricky to confirm. There might be a couple of reasons why you have not received your funds yet:
The transaction is not confirmed by the Blockchain network
Your payment is not confirmed yet by the blockchain network. Crypto transactions need to have at least two confirmations to be considered as completed. Please wait and your payment will be confirmed soon and you will receive some emails once the payment is processed.

You can check the number of confirmations from the below section:
Overpaid, Underpaid, or Delayed Payment
Overpaid: An overpayment indicates that we have detected an amount greater than we expected—the most common reason for this occurring is your wallet used a significantly different exchange rate than Coinbase Commerce. To prevent this to happen, you must enter the exact amount of crypto you see on the checkout page – Not the equivalent USD.
Underpaid: An underpayment indicates that we have detected an amount less than what was requested—the most common reason for this occurring is your customer’s wallet used a significantly different exchange rate than Coinbase Commerce. To prevent this to happen, you must enter the exact amount of crypto you see on the checkout page – Not the equivalent USD.
The other reason for this error could be deducing the transaction fee from the value you must pay. You need to pay the transaction fee from your wallet, not the amount you are sending to the blockchain.
Delayed Payment: You have used a low transaction fee and we have not received the payment after 8 hours. Always use a reasonable transaction fee to get confirmations in less than 30 minutes.
To resolve the overpaid, underpaid, and delayed payments, you need to contact support by opening a ticket. The billing team will check the transaction and confirm it according to the amount we have received. Do not forget to include the TXID while opening a ticket.
Does Coinbase support Binance Chain (BEP-2)?
Because Binance Chain (BEP-2) is a different blockchain that is not linked with Coinbase, they do not yet support it. Binance developed the BEP-2 blockchain primarily to enable faster asset transfers for its users. Your money will be lost if you make any deposits into a Coinbase account using the Binance Chain.
Coinbase supports ERC20 tokens on the Ethereum network, such as USD Coin (USDC) and Tether (USDT). You will lose your money if you transmit USDC to Coinbase on the BEP-2 chain because it is on a different network.
