Rollup State Root Challenge Tool

WHAT IT DOES

The Rollup State Root Challenge Tool enables users to challenge proposed state roots in rollup contracts. It reads rollup contract state for L1 rollup and state root chain contracts, user address, wallet balance, and state root data including proposed root, block number, and timestamp. The tool processes challenge parameters such as challenge period and dispute window, fraud proof data, gas price, base fee, block timestamp, chain ID, transaction nonce, approval state, contract owner state, and challenge status. It supports challengeStateRoot for single root challenges, batchChallengeRoots for multiple roots in one transaction, and challengeWithProof for proof-attached challenges.

HOW TO USE

Connect your wallet and select the target network (L1). Enter the rollup contract address, the state root to challenge (32-byte hex), and the L2 block number associated with that root. Optionally provide fraud proof data for challengeWithProof. Choose the execution method (challengeStateRoot, batchChallengeRoots, or challengeWithProof). The tool will fetch the rollup state, display the challenge period, dispute window, and current challenge status. Once confirmed, it submits the challenge transaction. The tool validates the state root format and block number before signing.

TECHNICAL MECHANISM

Unlike standard dispute tools, this executor is purpose-built for rollup state root challenge workflows. It first reads the rollup contract's isActive() to ensure the contract is operational. The tool fetches getChallengePeriod() and getDisputeWindow() to display the time parameters for challenges. It reads challengeStatus() to check if the specified root is already under challenge. The tool selects the optimal method: challengeStateRoot for standard challenges, batchChallengeRoots for multiple roots in one transaction, or challengeWithProof for challenges with fraud proof data. The state root is validated as a 32-byte hex value. Gas costs are calculated using receipt.effectiveGasPrice for accurate post-EIP-1559 fee accounting. The tool displays the challenge status before and after submission.

WHAT IT CANNOT SEE

This tool cannot verify that the fraud proof is correct beyond the contract's verification. It cannot detect if the state root was generated correctly or if the challenge will succeed. It also cannot guarantee that the challenge will be resolved in the user's favor. The tool cannot verify the authenticity of the fraud proof data or detect if the proof has been forged. It also cannot detect if the rollup contract has been paused or upgraded.

PLEASE NOTE

This tool supports EVM-compatible chains. Challenging a state root is a serious action—verify all data carefully before signing. The rollup contract must implement the challenge functions expected by this tool. Fraud proof data must be generated correctly off-chain. Batch challenges use arrays of roots and block numbers; ensure all data is correctly aligned. This tool does not resolve challenges—only submits them. For resolution monitoring, use the Rollup State Root Monitor.
