Validity Proof Submission Helper

WHAT IT DOES

Validity Proof Submission Helper is a non-custodial tool that submits cryptographic validity proofs for ZK-rollups and validity-based systems, proving correct state transitions and enabling efficient verification of off-chain computation. It reads validity proof contract state, user address, token balances, proof parameters, proof type, proof data, verification key, public inputs, proof commitment, submission window status, proof deadline, user's proof history, verification status, proof format requirements, circuit ID, proving system type, and L1/L2 bridge state to structure the optimal proof submission operation. With a single transaction, it calls submitValidityProof(), proveValidity(), or executeValidityProof() on the target contract, submitting the proof, verification key, and public inputs for on-chain verification. The tool supports various proving systems including zkSNARKs and zkSTARKs, enabling efficient verification of off-chain computation.

HOW TO USE

1. Connect your wallet (EVM-compatible on L1).

2. Paste the validity proof contract address.

3. Enter the proof type (e.g., zkSNARK, zkSTARK) and circuit ID.

4. Provide the verification key, public inputs, and proof data.

5. Review the verification status and submission deadline.

6. Click "submit validity proof" and confirm the transaction in your wallet.

The tool checks verification status and submission deadline before execution to prevent failed transactions. After the transaction confirms, your validity proof is submitted—no centralized custody, no intermediaries. The proof is verified on-chain, and if accepted, the state transition is finalized.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH FORMAT VERIFICATION

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts submitValidityProof(), then falls back to proveValidity() or executeValidityProof() 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 submission 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, the verification key matches the circuit, and all required fields are complete before execution.

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 submission window is still open. It cannot protect against loss if the proof is rejected. It cannot verify that the verification key matches the circuit. It cannot guarantee that the proof will be verified 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, proof parameters, and verification keys before executing. Validity proofs are cryptographic proofs that require correct formatting and matching verification keys—submitting malformed proofs may result in rejection and gas loss. The submission window is limited—proofs must be submitted before the deadline expires. The tool is provided as-is; use at your own risk.
