Transaction Risk Traffic Light

WHAT IT DOES

Transaction Risk Traffic Light reads pending transaction data from your wallet or a transaction hash, decodes the function name and arguments, and assigns a risk level using a traffic light system: GREEN for low-risk routine transactions, YELLOW for medium-risk transactions requiring caution, and RED for high-risk transactions you should strongly consider not signing. The tool analyzes the function type, arguments, value, and contract context, and generates an AI explanation of why the transaction received its risk rating.

HOW TO USE

When your wallet prompts you to sign a transaction, copy the transaction hash from your wallet or the requesting dApp. Open the Transaction Risk Traffic Light, connect your EVM wallet, and paste the transaction hash into the input field. Click "Look up transaction" to fetch the details and generate a risk assessment. Alternatively, click "Manual entry" to enter the contract address, function name, arguments, and value directly. The tool will display the transaction details, a risk level with a colored traffic light indicator, and a list of reasons for the rating. Review the AI explanation to understand why the transaction is rated green, yellow, or red, then verify the details in your wallet before signing.

TECHNICAL SECTION — TRANSACTION RISK ASSESSMENT

The tool fetches transaction data from the blockchain using the connected wallet's provider. It extracts the contract address, value, data payload, gas limit, and gas price. The data payload is decoded using a built-in signature lookup table for common functions including transfer, approve, setApprovalForAll, permit, swap, mint, and claim. The tool applies a set of risk heuristics: approve and setApprovalForAll are flagged as medium or high risk depending on the scope, swaps are medium risk, transfers with value are medium risk, and routine view functions are low risk. Unknown functions default to yellow. The AI layer receives the decoded data and current wallet context, generating a plain-language assessment with a color rating. This approach provides a simple, visual risk indicator that helps you make faster, more informed signing decisions.

WHAT IT CANNOT SEE

This tool cannot read the actual intent behind a transaction. It cannot determine if a contract or spender is malicious without an external database. It cannot detect social engineering attacks. It cannot predict future state changes. It cannot detect off-chain risks. It cannot guarantee that the risk assessment is complete or accurate. The user must still verify the transaction details in their wallet before signing. The AI assessment is generated from on-chain data and does not constitute financial advice or a guarantee of safety.

PLEASE NOTE

EVM chains only. Assessments are AI-generated from data the app reads on-chain—always review what you are actually signing in your wallet before approving it. The wallet's own signature prompt remains the final and only protection against unwanted transactions. This tool is read-only; it never sends transactions or signs anything on your behalf.
