Stuck on Polygon? How to Fix Gas Problems and Pending Transactions

If you have ever been stuck with a pending transaction on Polygon and zero MATIC for gas, you know how frustrating it can be. Here is exactly what you need to know to get unstuck.

The Problem

Polygon gas prices can spike from 30 gwei to 300 gwei in minutes. If you submitted a transaction at low gas, it gets stuck. While it is pending, all subsequent transactions are blocked because they use higher nonces. You are effectively locked out of your wallet.

The Diagnosis

Check your pending vs latest nonce. If pending is higher than latest, you have stuck transactions. Each stuck transaction blocks one nonce slot.

You can check this on Polygonscan by searching your address and looking at the pending transactions tab. Or use web3.py to query get_transaction_count with the pending parameter.

Three Solutions

Option 1: Wait It Out

Pending transactions eventually drop from the mempool. This typically takes one to twenty-four hours depending on the node configuration. If you are not in a hurry, just wait. The transaction will either confirm when gas drops or expire from the mempool.

Option 2: Speed Up or Cancel

MetaMask and most wallets have a Speed Up or Cancel button for pending transactions. Canceling sends a zero-value transaction to yourself with the same nonce but higher gas. This replaces the stuck transaction and clears the nonce.

The catch: canceling also requires gas. If you have zero MATIC, this option does not work.

Option 3: Use a Faucet or Get MATIC from Another Source

If you need a tiny amount of MATIC to clear stuck transactions, options include asking a friend to send you a small amount, using a centralized exchange withdrawal, or bridging tokens from another chain where you have gas tokens.

Prevention

Always keep at least 0.01 MATIC in your wallet for gas. Monitor gas prices before submitting transactions. Use gas trackers to find low-congestion periods. Consider using relayers like Biconomy for gasless transactions on supported dApps.
