L2 Sequencer Fee Rebate Claim Tool

WHAT IT DOES

The L2 Sequencer Fee Rebate Claim Tool enables users to claim fee rebates from L2 sequencers for transaction fees paid on Layer 2 networks. It reads sequencer fee rebate contract state, user address, wallet balance, and L2 transaction history. The tool processes transaction fee data, rebate eligibility, rebate amount, rebate claim status, and rebate claim deadline. It supports claimRebate for single rebate claims, batchClaimRebates for multiple claims in one transaction, and claimWithProof for proof-based claims. The tool reads gas price, base fee, block timestamp, chain ID, transaction nonce, approval state, contract owner state, and sequencer state before execution.

HOW TO USE

Connect your wallet and select the target network. Enter the rebate contract address and the rebate ID or transaction batch ID. Optionally enter proof data if using claimWithProof. Choose the execution method (claimRebate, batchClaimRebates, or claimWithProof). The tool will fetch the rebate state, display the rebate amount, eligibility, claim deadline, and claim status. It also shows the current sequencer state. Once confirmed, it submits the claim transaction. The tool checks if the rebate has already been claimed and warns before proceeding.

TECHNICAL MECHANISM

Unlike generic claim tools, this executor is purpose-built for L2 sequencer fee rebate workflows. It first reads the rebate contract's isActive() to ensure the contract is operational. The tool fetches sequencerState() to verify the sequencer is online and processing rebates. It checks eligibility via isEligible() and rebate amount via getRebateAmount() to display the user's claimable rewards. The tool checks claim status using isClaimed() to prevent duplicate claims. It reads the claim deadline via getClaimDeadline() to warn if the claim window has expired. It selects the optimal method: claimRebate for standard claims, batchClaimRebates for multiple claims in one transaction, or claimWithProof for proof-based claims when eligibility is not directly queryable. Gas costs are calculated using receipt.effectiveGasPrice for accurate post-EIP-1559 fee accounting. The tool displays the sequencer state and rebate amount in native token units.

WHAT IT CANNOT SEE

This tool cannot verify that the transaction fee data is accurate or that the rebate amount is correctly calculated. It cannot detect if the rebate has been claimed already or if the claim window has expired. It also cannot guarantee that the sequencer will process the rebate claim correctly. The tool cannot verify the authenticity of proof data or detect if the proof has been compromised. It also cannot detect if the sequencer has been paused or if the rebate contract has been upgraded.

PLEASE NOTE

This tool supports EVM-compatible chains. Claiming a rebate is irreversible—verify eligibility, amount, and deadline before proceeding. The rebate contract must implement the claim functions expected by this tool. For claimWithProof, proof data must be generated off-chain. Batch claims use arrays of rebate IDs and users; ensure all data is correctly aligned. This tool does not track L2 transaction history—for that, use the L2 Transaction History Tool.
