Approval Grant Plain-Language Explainer

WHAT IT DOES

The Approval Grant Plain-Language Explainer reads the parameters of a pending approve() or setApprovalForAll() transaction and translates them into plain English—before you sign. You enter the token address, spender address, approval type, and amount. The tool fetches the token symbol, your current token balance, your current allowance for that spender, and checks whether the spender is a contract or EOA. It then uses AI to generate a clear, non‑technical explanation of exactly what the approval grants, whether it's unlimited or capped, and what the spender can do with your tokens. This helps you understand what you're signing in plain language.

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 approval type.

4. For approve(), enter the allowance amount or "unlimited".

5. Optionally set the token decimals (defaults to 18).

6. Click "Explain approval" to fetch data and generate an explanation.

7. Review the plain‑language explanation along with the raw data.

8. The wallet's own signature prompt will still appear—this tool only informs you.

THE REAL MECHANISM — token metadata read with AI‑powered plain‑language translation

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 or EOA. The tool builds a structured prompt for the AI bridge (BGAI.generate) with the token symbol, spender address, approval type, allowance amount, current allowance, balance, and spender type. The AI returns a plain‑language explanation of what the approval does. The tool displays both the raw data and the AI explanation side by side, so you can see the transaction details and the explanation together.

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.

- For setApprovalForAll, the allowance is always unlimited (all tokens).
