How to Fix a Pending Polygon Transaction

Transactions on Polygon PoS are prioritized by gas price. Validators pick the highest-paying transactions first. If you submitted a transaction with a very low gas price during a period of network congestion, your transaction may sit in the mempool waiting to be picked up. A transaction can also be stuck if a previous transaction from the same wallet address has not confirmed — because Polygon processes transactions in sequential nonce order.

In MetaMask or a compatible wallet, find the pending transaction and select the 'Speed Up' option. This resubmits the same transaction with a higher gas price, effectively replacing it in the mempool. Use the 'Fastest' preset to ensure it confirms within seconds. The same nonce is used, so only one version of the transaction will confirm.

If you want to cancel the transaction entirely, send a 0 MATIC transaction to your own address using the same nonce but a much higher gas price. This replaces the original pending transaction with a harmless one. Once this cancellation transaction confirms, the original is discarded by the network.

Go to polygonscan.com and search your wallet address or transaction hash. Look at the 'Pending' tab to see any unconfirmed transactions. Note the nonce value — you need this if manually resubmitting. If the transaction shows a very low gas price compared to the current network average, that is the cause of the delay.
