NFT Collection Approval Risk Explainer

WHAT IT DOES

NFT Collection Approval Risk Explainer reads pending setApprovalForAll transaction data from your wallet or a transaction hash, decodes the NFT collection address, spender address, and whether the approval is being set or revoked. It checks your NFT holdings in that collection and retrieves the collection name and symbol. The tool then explains the risk of granting approval for the entire collection, describing what the spender could do, which NFTs would be affected, how many NFTs you own, and what risks to consider before signing.

HOW TO USE

When your wallet prompts you to sign an NFT collection approval transaction, copy the transaction hash from your wallet or the requesting dApp. Open the NFT Collection Approval Risk Explainer, connect your EVM wallet, and paste the transaction hash into the input field. Click "Look up transaction" to fetch the approval details and generate a risk explanation. Alternatively, click "Manual entry" to enter the collection address, spender address, and action directly. The tool will display the collection name and symbol, spender address, your NFT holdings, and a risk level with a detailed explanation. Review the AI explanation to understand the risk, then verify the details in your wallet before signing.

TECHNICAL SECTION — NFT COLLECTION APPROVAL RISK ASSESSMENT

The tool fetches transaction data from the blockchain using the connected wallet's provider. It decodes the function signature to confirm it is setApprovalForAll, then extracts the spender address and the boolean approval value. The tool also retrieves the user's NFT balance in the collection via balanceOf RPC calls and fetches collection metadata (name and symbol). The risk assessment considers: whether the approval is being set or revoked, the number of NFTs the user owns in the collection, and whether the approval is unlimited (setApprovalForAll grants permission for ALL NFTs in the collection). The AI layer receives the decoded data and user holdings, generating a plain-language risk explanation. This approach helps you understand the potential impact of an NFT collection approval before you sign.

WHAT IT CANNOT SEE

This tool cannot read the actual intent behind an approval transaction. It cannot determine if the spender address is malicious without an external database. It cannot detect if the spender will transfer NFTs or use the approval maliciously. It cannot detect if the approval has been revoked at the time of the check. It cannot verify if the collection contract is legitimate. The user must still verify the transaction details in their wallet before signing. The AI explanation is generated from on-chain data and does not constitute financial advice or a security guarantee.

PLEASE NOTE

EVM chains only. Explanations 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 approvals. This tool is read-only; it never sends transactions or signs anything on your behalf.
