Speed Up Pending Transaction

WHAT IT DOES

This tool accelerates a stuck or slow pending transaction by replacing it with an identical transaction that uses a higher gas price. When you submit a transaction with a gas price that is too low, it can remain pending for hours or even days. This tool lets you resubmit the same transaction (same nonce, same recipient, same value, same data) with a higher gas price, giving it priority over the original in the mempool. The tool reads the current transaction status by hash, including nonce, gas price, gas limit, and confirmation state. It then calculates a new gas price based on your chosen multiplier and broadcasts the replacement transaction.

HOW TO USE

Connect your EVM wallet (MetaMask, WalletConnect, Coinbase Wallet, etc.) to the tool. Enter the transaction hash of the stuck pending transaction. Adjust the gas multiplier (e.g., 1.2 for 20% higher gas) — the higher the multiplier, the faster the transaction will likely be picked up by miners/validators. Click "Look up transaction" to verify the transaction is still pending and was sent from your wallet. Review the original gas price and the proposed new gas price. Click "Speed up transaction" to sign and broadcast the replacement. The tool will wait for confirmation and notify you of the result.

TECHNICAL MECHANISM: NONCE REPLACEMENT WITH HIGHER GAS

Ethereum and EVM-compatible chains use a nonce (transaction count) to order transactions from each address. A transaction with a specific nonce can only be mined once. By broadcasting a new transaction with the same nonce but a higher gas price, you effectively replace the original pending transaction — miners will see the higher-gas version and prioritize it. The original transaction becomes invalid because the nonce is already used. The tool preserves all original transaction parameters (to, value, data, gas limit) to ensure the replacement performs exactly the same operation. It calculates the new gas price by multiplying the original gas price by your chosen multiplier, ensuring it is high enough to get attention without overpaying unnecessarily.

WHAT IT CANNOT SEE

This tool cannot speed up transactions that have already been confirmed — once a transaction is on-chain, it cannot be replaced. It cannot speed up transactions sent from addresses other than your connected wallet for security reasons. It cannot guarantee that the replacement will be mined before the original — if the original is included in a block before the replacement propagates, the speed-up will fail. It cannot detect stuck transactions automatically — you must provide the transaction hash. It cannot speed up transactions on non-EVM chains. The tool does not analyze network congestion or suggest optimal gas prices — it simply applies your multiplier to the original gas price. Speed-up transactions require additional gas fees, which are not refundable.

PLEASE NOTE

This tool works exclusively on Ethereum Virtual Machine (EVM) compatible chains including Ethereum Mainnet, Polygon, Arbitrum, Optimism, Base, BSC, Avalanche C-Chain, and others. It does not support Solana, Bitcoin, Cosmos, or any non-EVM architecture. A higher gas multiplier may not guarantee faster confirmation during extreme network congestion — consider checking current network conditions. The replacement transaction will use the same nonce as the original, meaning if the original is mined first, the replacement will fail with a "nonce already used" error. This is normal behavior. Always verify the transaction details before speeding up — you are signing a new transaction that will incur additional gas costs.
