Transaction Speed-Up Tool

WHAT IT DOES

Transaction Speed-Up Tool is a wallet-focused tool that enables users to accelerate pending transactions by replacing them with higher gas prices. Unlike manual transaction resubmission, which requires constructing and signing transactions from scratch, this tool automates the entire process. It reads pending transaction details, extracts the original gas price, checks the current network gas price, validates the transaction nonce, verifies wallet balance, and monitors transaction pool status. The tool supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche, BNB Chain, and Base, providing a unified interface to speed up transactions across multiple networks. This is essential for users waiting on low-gas transactions during network congestion, enabling them to reduce confirmation times from hours to minutes.

HOW TO USE

Connect your wallet using WalletConnect or a compatible browser extension. Ensure your wallet is on the network where the pending transaction was submitted. Enter the transaction hash of the stuck transaction. Enter the original gas price in gwei (the value you submitted with) and set a gas multiplier—typically 1.2x to 2.0x, with higher values giving faster confirmation but costing more. Click "Check transaction" to verify the transaction status and calculate the required replacement gas price. The tool displays a gas comparison showing the original gas, the new gas, and the current network gas price. If the transaction is pending and you have sufficient balance, the "Speed up transaction" button appears. Click it to submit a replacement transaction with the same recipient, value, and data, but with the higher gas price. The tool displays a transaction link to your chain's block explorer and logs the final gas cost using receipt.effectiveGasPrice for accurate post-EIP-1559 fee tracking.

ADAPTIVE GAS PRICE REPLACEMENT ENGINE

The core technical mechanism that distinguishes this tool is its adaptive gas price replacement engine. Unlike simple transaction resubmission, this tool calculates an optimal replacement gas price based on multiple factors. The engine first reads the original transaction details using eth_getTransactionByHash, extracting the nonce, gas price, gas limit, recipient, value, and data. It then retrieves the current network gas price using eth_gasPrice. The engine applies the user's multiplier to the original gas price, then compares it to the current network price. If the multiplied price is lower than the current network price, the engine automatically raises it to at least 110% of the network price to ensure the replacement transaction is competitive. The engine also validates that the wallet has sufficient native balance to cover the new gas cost, subtracting the fee from the balance as required by PLAYBOOK-C §5 rule 3. The replacement transaction preserves the original recipient, value, and data, only modifying the gas price and ensuring the same nonce is used. All RPC calls are wrapped with timeout and retry logic, and the tool automatically falls back to a secondary provider if the primary endpoint fails or rate-limits, ensuring the status check completes even during network congestion.

WHAT IT CANNOT SEE

The tool cannot guarantee that a transaction will be sped up if the network is severely congested, the replacement transaction is front-run by another transaction with an even higher gas price, the wallet's nonce is already used by a different transaction, or the gas price increase is insufficient to outpace the network's rising gas prices before the original is mined. It has no visibility into the exact mempool state across all nodes, nor can it predict how quickly miners will pick up the replacement transaction. The tool cannot detect if the original transaction has already been mined between the check and the speed-up submission. It does not monitor transactions after speed-up—it is a speed-up tool, not a transaction monitoring service. The tool cannot interact with non-EVM chains, private networks, or wallets that do not support standard EIP-1559 or legacy transaction replacement.

PLEASE NOTE

This tool is designed exclusively for EVM-compatible blockchain networks. It supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche, BNB Chain, Base, and similar chains. Non-EVM networks such as Solana, Cosmos, or Bitcoin are not supported. Always verify the transaction hash and gas parameters before speeding up—the tool does not validate transaction safety or legitimacy beyond basic verification. The tool provides estimates only—actual fees and gas costs are determined at the time of transaction execution. Users are responsible for understanding the risks of transaction speed-up, including the possibility that the original transaction may still be mined if the replacement is not processed in time.
