About this app
WHAT IT DOES
The Token Allowance Danger Summary reads the parameters of a pending approve() or setApprovalForAll() transaction and provides a plain‑language danger summary—SAFE, CAUTION, or DANGER—before you sign. You enter the token address, spender address, and allowance amount. The tool fetches the token symbol, your current token balance, your current allowance for that spender, and checks whether the spender is a verified contract or an EOA. It then uses AI to generate a one‑word danger level and a concise explanation of whether the approval is unlimited, exceeds your balance, or goes to an unverified contract.
HOW TO USE
1. Connect your EVM wallet (required to read your balance and allowance).
2. Select the chain (Ethereum, Polygon, or Arbitrum).
3. Enter the token contract address, spender address, and allowance amount.
4. Optionally set the token decimals (defaults to 18).
5. Click "Summarize danger" to fetch data and generate a summary.
6. Review the danger level (SAFE/CAUTION/DANGER) and the AI explanation.
7. The wallet's own signature prompt will still appear—this tool only informs you.
THE REAL MECHANISM — balance and allowance comparison with AI danger scoring
This tool reads from the token contract using standard ERC-20 interfaces: `symbol()` for the token name, `balanceOf(address)` for your current balance, and `allowance(address, address)` for your current approved amount. It also reads `eth_getCode` on the spender address to determine if it's a contract and uses a heuristic (code length) to estimate verification status. The tool then classifies the danger level: DANGER if the approval is unlimited to an EOA or unverified contract, or if it exceeds your balance by more than 2x; CAUTION if it's unlimited to a verified contract or exceeds your balance; SAFE otherwise. It builds a structured prompt for the AI bridge (BGAI.generate) with all collected data, and the AI returns a plain‑language danger summary with the danger level.
WHAT IT CANNOT SEE
- This tool cannot read the exact intent behind the approval—only the on‑chain parameters.
- It cannot determine if the spender contract is malicious with certainty.
- It cannot detect approvals that are submitted through a wallet interface without page interaction.
- It cannot read off‑chain agreements or promises related to the approval.
- It cannot decode custom function signatures that are not in the standard ABI set.
- It cannot prevent you from signing a transaction—it only provides information.
PLEASE NOTE
- This tool works on Ethereum (1), Polygon (137), and Arbitrum (42161).
- The AI explanation is generated from the data you provide and is for guidance only. Always review the actual transaction details in your wallet before signing.
- The wallet's own signature prompt is what actually protects you—the AI's read is not a substitute for reviewing what you sign.
- The danger level is a heuristic—use it as a signal, not a definitive judgment.
