Wrong Network Warning Explainer

WHAT IT DOES

Wrong Network Warning Explainer is a read-only tool that analyzes your wallet's current network and compares it to the intended network for a contract interaction, warning you if there's a mismatch. It reads the current wallet network chain ID, target contract address, contract's deployed chain ID, bytecode hash, network-specific contract deployment patterns, known cross-chain addresses, ENS records, block explorer metadata, wallet connection state, transaction target address, chain-specific token addresses, and bridge contract addresses. The tool then presents this data alongside an AI-generated warning explaining the specific risks of proceeding on the wrong network and suggesting the correct network — helping you avoid costly mistakes before signing a transaction.

HOW TO USE

Connect your wallet using the BGWallet bridge and select your target network. Enter the contract address you intend to interact with. Optionally specify the intended network chain ID (defaults to the currently selected network). Click "Check network" to read on-chain data. The tool displays the contract address, your wallet's connected network, the intended network, network status (Correct/Wrong), and the contract's deployed chain. A prominent warning banner appears if you're on the wrong network, telling you which network you should switch to. Detailed information includes bytecode hash, deployment pattern, known cross-chain address, contract name, ENS record, block explorer identification, and bridge contract address. An AI explanation appears below the on-chain data, warning when your wallet is connected to the wrong network, explaining the specific risks of proceeding, and suggesting the correct network before you sign a transaction. The wallet's own signature step still protects you — this explanation is informational only and does not replace reviewing what you approve in your wallet.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 with the provider from the BGWallet bridge to read on-chain data from the contract you specify. No hardcoded contract addresses are used — you are always in control of which contract you trust. When detecting network mismatches, the tool reads the current wallet network chain ID via BGWallet.getChainId(), reads the target contract address from the user input, reads the contract's deployed chain ID by analyzing the contract's creation transaction or metadata (via block explorer APIs or contract creation receipts), reads the bytecode hash via provider.getCode(contract) to compute the keccak256 hash for comparison, reads network-specific contract deployment patterns by comparing the bytecode and metadata against known patterns for each chain, reads known cross-chain addresses from a local or API-based database, reads ENS records via the ENS resolver, reads block explorer metadata via API, reads wallet connection state via BGWallet.isConnected(), reads the transaction target address from the user input or pending transaction, reads chain-specific token addresses from a local or API-based database, and reads bridge contract addresses from known bridge registries. The tool fetches event logs by walking backwards in chunks and halving chunk size on failure, ensuring logs are properly read despite varying RPC limitations. The data is formatted and passed to the AI bridge via BGAI.generate() with a structured prompt that includes all the on-chain data read. The AI is instructed to warn when a wallet is connected to the wrong network, explain the specific risks of proceeding, and suggest the correct network — while stating plainly that it cannot detect malicious RPC providers that lie about the chain ID, and cannot prevent a user from manually approving a transaction on the wrong network. The AI response is capped at 1,024 tokens to ensure concise, focused network warnings. All computed values are guarded against negative numbers — if a chain ID or block number appears invalid, the tool flags it rather than displaying nonsensical values.

WHAT IT CANNOT SEE

This tool cannot detect contracts deployed via proxies that report a different chain ID. It cannot verify that the contract's behavior is identical across chains. It cannot detect malicious RPC providers that lie about the chain ID. It cannot prevent a user from manually approving a transaction on the wrong network. The AI explanation is generated from on-chain data only and cannot detect proxy pattern implementation details, off-chain proxy logic, or intent behind cross-chain deployments. It cannot predict future network changes, proxy upgrades, or cross-chain bridge failures. The tool does not continuously monitor the wallet network; each analysis is a snapshot at the time of the lookup. It cannot detect delayed proxy updates, off-chain network mismatches, or stale metadata. The tool does not store any data persistently; all state is in-memory and resets on reload. The AI explanation is informational and does not constitute financial advice, legal advice, or a guarantee of contract safety or correct network identification.

PLEASE NOTE

Wrong Network Warning Explainer works exclusively with EVM-compatible chains. It requires a Web3 wallet (MetaMask or similar) and the BGWallet bridge. Explanations are AI-generated from data the app reads on-chain — always review what you are actually signing in your wallet before approving it. Always verify the contract address you are using — the tool does not validate or endorse any contracts. Interacting with a contract on the wrong network carries significant risk including loss of funds, failed transactions, and unintended contract behavior. Use this tool as a guide only; always cross-check with your wallet's network display and the protocol's official documentation for critical decisions. This is experimental software; use at your own risk.
