WHAT IT DOES
Fraud Proof Submission Tool is a non-custodial tool that submits cryptographic fraud proofs to prove invalid state transitions in optimistic systems, enabling security through verification. It reads fraud proof contract state, user address, token balances, proof parameters, challenged block/batch ID, proof data, predecessor state, successor state, challenge window status, proof deadline, user's proof history, validator bond, verification status, dispute period, proof format requirements, and L1/L2 bridge state to structure the optimal proof submission operation. With a single transaction, it calls submitFraudProof(), proveFraud(), or executeFraudProof() on the target contract, providing cryptographic evidence of invalid state transitions and staking a validator bond. The tool is essential for maintaining the security of optimistic systems by allowing anyone to submit proofs of fraud.
HOW TO USE
1. Connect your wallet (EVM-compatible on L1).
2. Paste the fraud proof contract address.
3. Enter the challenged block/batch ID, predecessor state, and successor state.
4. Provide the fraud proof data and validator bond amount.
5. Review the verification status and proof deadline.
6. Click "submit fraud proof" and confirm the transaction in your wallet.
The tool checks verification status and proof deadline before execution to prevent failed transactions. After the transaction confirms, your fraud proof is submitted—no centralized custody, no intermediaries. The bond is staked and will be returned if the proof is accepted, or forfeited if the proof is rejected.
TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH BOND VERIFICATION
Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts submitFraudProof(), then falls back to proveFraud() or executeFraudProof() if the primary method fails—automatically adapting to different contract implementations without requiring the user to know the exact function name. For all on-chain reads, it uses chunked block range scanning that halves on failure, preventing the common "eth_getLogs limit exceeded" error that halts most scanners on public RPCs. It double-verifies proof eligibility by checking both the current challenge window status and verification status from storage, rather than relying on historical events—because an event log proves a previous proof was submitted, not that the current proof can be accepted. Gas estimation uses receipt.effectiveGasPrice for accurate post-EIP-1559 cost accounting, and all batched operations are sequential with concurrency caps to avoid nonce conflicts. The tool also validates that the proof data is properly formatted and that the bond amount meets the contract's requirements.
WHAT IT CANNOT SEE
This tool cannot verify that the proof contract is legitimate or has not been compromised. It cannot detect if the proof data is actually valid or not. It cannot ensure that proof submission will execute at the optimal gas price due to network conditions. It cannot guarantee that proof will succeed if the contract is paused or frozen. It cannot verify that the contract has not been upgraded or modified. It cannot detect if the trade path is optimal or not front-run. It cannot recover funds if execution fails due to contract bugs or insufficient approval. It cannot verify that the proof data is correctly formatted or complete. It cannot predict market movements, price gaps, or flash crashes. It cannot guarantee execution during extreme network congestion or volatile market conditions. It cannot detect if the underlying system has been compromised. It cannot prevent the user from canceling or modifying proof parameters. It cannot ensure that the proof window is still open. It cannot protect against loss if the proof is rejected. It cannot verify that the bond will be returned. It cannot guarantee that the proof will be processed correctly. It cannot ensure that the proof data meets all technical requirements.
PLEASE NOTE
This tool operates only on EVM-compatible chains (Ethereum Mainnet, Polygon, Arbitrum, Optimism, etc.). It is non-custodial—you retain full control of your funds at all times. Always verify contract addresses and proof data before executing. Fraud proofs are serious actions that require valid cryptographic evidence—submitting invalid proofs may result in bond forfeiture. The proof deadline is limited—proofs must be submitted before the deadline expires. The tool is provided as-is; use at your own risk.
