Transaction Intent Explainer

WHAT IT DOES

Transaction Intent Explainer takes any Ethereum transaction and tells you what it actually does in plain English—not just the function name, but the real-world intent. It decodes the function signature, extracts all parameters, shows the value being transferred, and resolves known contract addresses to recognizable names (Uniswap, USDC, BAYC, etc.). An AI layer then translates the technical transaction data into a clear explanation of what the transaction is trying to accomplish, what permissions it requests, what assets are affected, and whether this is a normal operation or something unusual. You get this before your wallet ever asks for a signature—so you understand the intent, not just the data.

HOW TO USE

Connect your EVM wallet using the BotGentz wallet bridge. Select the network matching your transaction. Paste a transaction hash into the input field and click "Explain." The tool fetches the transaction from the chain, decodes the function, extracts parameters, looks up contract labels, flags any risks, and generates an AI explanation. Results show you the contract name (if known), sender, recipient, value, function name, decoded parameters, risk flags, and a plain-English explanation of what the transaction actually does. No transaction is ever submitted—this tool is read-only and free.

TECHNICAL MECHANISM

The app uses the injected BGWallet bridge to access the EVM provider via ethers.js v5.7.2. Transaction hashes are fetched via provider.getTransaction(), returning the full transaction object including to, from, value, data, gasLimit, and nonce. The call data is decoded against a built-in signature database of common functions—ERC20 transfer/approve, ERC721 safeTransferFrom/transferFrom, mint, owner, renounceOwnership, transferOwnership, pause, unpause, withdraw, selfdestruct, setApprovalForAll, and more. For each signature, the tool extracts parameters using regex on the hex data—pulling addresses (padded to 64 hex chars), uint256 values, and booleans. Contract addresses are resolved against a local label database for known protocols and tokens (Uniswap, DAI, USDC, USDT, WETH, BAYC, MAYC, etc.). A risk flagging system checks for dangerous patterns: unlimited approvals, ownership transfers, self-destruct, large value transfers, and admin functions. The AI bridge (BGAI.generate) receives a prompt with the decoded function name, parameters, value, raw data, detected flags, and contract label, and returns a concise plain-English explanation of intent capped at 1,024 tokens.

WHAT IT CANNOT SEE

This tool cannot detect malicious intent hidden in contract bytecode—it reads only the transaction data visible on-chain. It cannot verify off-chain intent or consequences of a transaction. It cannot guarantee that the displayed contract name matches the actual deployed code—contract labels are from a local database and may be incomplete or outdated. It cannot detect front-running, cross-contract attack vectors, or reentrancy vulnerabilities. It cannot verify that the displayed function signature matches the actual contract implementation—a malicious contract could implement a function with the same signature but different behavior. It does not simulate transaction execution, so it cannot predict revert conditions or gas exhaustion. The AI explanation is generated from the provided data and may miss nuanced attack patterns not present in the call data itself.

PLEASE NOTE

Supports EVM-compatible chains only—Ethereum, Sepolia, Polygon, Mumbai, Optimism, Arbitrum, and any network the wallet bridge connects to. Explanations are AI-generated and should be treated as assists, not authoritative audits. Always review the transaction details in your wallet's own signature prompt before approving. The wallet's signature step is the only protection that actually gates any action—this tool is informational and does not replace that safeguard. Free to use, no API keys required.
