Speed-Up Transaction Risk Explainer

WHAT IT DOES

Speed-Up Transaction Risk Explainer is a read-only tool that analyzes the risk of speeding up a pending transaction, generating AI-powered plain-language explanations of speed-up viability and strategies. It reads pending transaction status, transaction nonce, sender address, original gas price, current block number, mempool state, transaction hash, calldata, confirmation count, gas price trends, network congestion, pending pool depth, transaction age, replacement transaction viability, recommended gas price bump, miner and validator behavior, and block inclusion probability. The tool then presents this data alongside an AI-generated explanation of the risk of speeding up a pending transaction, recommending optimal gas price adjustments and analyzing the trade-offs between speed, cost, and success likelihood — helping you decide whether to speed up a transaction before submitting a replacement.

HOW TO USE

Connect your wallet using the BGWallet bridge and select your target network. Enter the transaction hash you want to speed up. Optionally enter the sender address (auto-detected if not provided). Click "Analyze speed-up risk" to read mempool and on-chain data. The tool displays the transaction hash, sender address, nonce, original gas price, recommended gas price, and speed-up risk level (Low/Medium/High). Detailed information includes transaction age, mempool state, gas price trend, network congestion, pool depth, block inclusion probability, miner and validator behavior, replacement viability, and calldata hash. A recommended strategy box provides specific guidance on gas price adjustment percentages and timing. An AI explanation appears below the on-chain data, explaining the risk of speeding up the pending transaction, recommending optimal gas price adjustments, and analyzing the trade-offs between speed, cost, and success likelihood before you submit a replacement transaction. The wallet's own signature step still protects you — this explanation is informational only and does not replace reviewing what you approve in your wallet.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 with the provider from the BGWallet bridge to read mempool and on-chain data. No hardcoded contract addresses are used — you are always in control of which contract you trust. When analyzing speed-up risk, the tool reads the pending transaction status via provider.getTransaction(txHash) and checking if it exists, reads the transaction nonce from the transaction object, reads the sender address from the transaction, reads the original gas price from the transaction, reads the current block number via provider.getBlockNumber(), reads the mempool state by checking for the transaction in the mempool, reads the transaction hash from the user input, reads the calldata from the transaction object, estimates confirmation count based on gas price, analyzes gas price trends from recent blocks and mempool, assesses network congestion from the pending transaction count, reads the pending pool depth via provider.getPendingTransactions().length, calculates transaction age by comparing block timestamps, analyzes replacement transaction viability by checking whether a speed-up replacement is likely to be accepted, calculates a recommended gas price bump based on network conditions and original gas price, reads miner and validator behavior from block proposer histories and mempool patterns, and estimates block inclusion probability by comparing the recommended gas price to current mempool gas prices. The tool fetches event logs by walking backwards in chunks and halving chunk size on failure, ensuring logs are properly read despite varying RPC limitations. The data is formatted and passed to the AI bridge via BGAI.generate() with a structured prompt that includes all the on-chain data read. The AI is instructed to explain the risk of speeding up the pending transaction, recommend optimal gas price adjustments, and analyze the trade-offs between speed, cost, and success likelihood — while stating plainly that it cannot guarantee that a speed-up transaction will be mined before the original, cannot predict exact block inclusion timing or validator prioritization, and cannot guarantee that the recommended gas price will be sufficient. The AI response is capped at 1,024 tokens to ensure concise, focused speed-up risk assessments. All computed values are guarded against negative numbers — if a gas price or nonce appears invalid, the tool flags it rather than displaying nonsensical values.

WHAT IT CANNOT SEE

This tool cannot guarantee that a speed-up transaction will be mined before the original. It cannot predict exact block inclusion timing or validator prioritization. It cannot detect if the original transaction has been picked up by a private miner before the speed-up is broadcast. It cannot guarantee that the recommended gas price will be sufficient. The AI explanation is generated from public mempool and on-chain data only and cannot detect private transaction inclusion, hidden miner behavior, or validator collusion. It cannot predict whether a speed-up will be prioritized by the next block proposer. The tool does not continuously monitor speed-up attempts; each analysis is a snapshot at the time of the lookup. It cannot detect delayed speed-ups, private transaction pools, or stale mempool data. The tool does not store any data persistently; all state is in-memory and resets on reload. The AI explanation is informational and does not constitute financial advice, legal advice, or a guarantee of speed-up success or transaction safety.

PLEASE NOTE

Speed-Up Transaction Risk Explainer works exclusively with EVM-compatible chains. It requires a Web3 wallet (MetaMask or similar) and the BGWallet bridge. Explanations are AI-generated from data the app reads on-chain — always review what you are actually signing in your wallet before approving it. Speeding up a transaction carries significant risk including replacement failure, increased gas costs, and unintended transaction outcomes. Use this tool as a guide only; always cross-check with independent sources and monitor replacement transaction status. This is experimental software; use at your own risk.
