About this app
WHAT IT DOES
This tool tests shared sequencer integration by analyzing cross-chain sequencing contracts, rollup registrations, and ordering slot data. It provides a comprehensive assessment of whether a shared sequencer is correctly integrated with multiple rollup chains. The tool checks shared sequencer contract verification, rollup chain contract verification, sequencing slot management, cross-chain ordering modules, and validator gateway connectivity. Results are presented as a detailed integration test report with status indicators (online/pending/offline), component details, and an overall readiness score. This is essential for developers integrating shared sequencers, auditors verifying cross-chain sequencing correctness, and teams ensuring rollup chains are properly registered with shared sequencers.
HOW TO USE
Connect your wallet (read-only, no transaction required) and select the target network. Enter the integration name, shared sequencer contract address, rollup chain contract address, and set the lookback blocks for integration analysis. Click "test integration" and the tool will verify both contracts, analyze their status and sequencing event data, and generate a comprehensive integration report. Results display a summary with online component counts and overall readiness percentage, detailed integration cards showing each component's status and data, and a table of all integration components with their statuses. Use the report to identify integration gaps, verify cross-chain ordering correctness, and ensure shared sequencer readiness for production.
TECHNICAL MECHANISM
The analyzer uses ethers.js v5.7.2 to perform a multi-stage shared sequencer integration test. First, it calls eth_getCode to verify both the shared sequencer contract and the rollup chain contract are deployed and uses block explorer APIs to fetch verification status and source code. The tool then scans historical logs using eth_getLogs across the specified block range to identify sequencing events (e.g., SequencingSlotAllocated, BatchOrdered, CrossChainOrdered), rollup registration events, and cross-chain ordering events. It queries the contract state via eth_call to retrieve current component status, sequencing slot allocations, and rollup chain registration information. The tool analyzes each integration component: shared sequencer (checking if it's active and processing cross-chain ordering), rollup chain (checking if it's properly registered), sequencing slot manager, cross-chain ordering module, and validator gateway. It calculates overall readiness based on multiple factors: contract verification status, component activity, slot allocation health, and cross-chain ordering consistency. Each component is assigned a status: online (fully operational), pending (available but not fully active), or offline (not ready). Results are compiled into a structured report with detailed component information, status indicators, and an overall readiness score.
WHAT IT CANNOT SEE
This tool cannot actually test shared sequencing or cross-chain ordering—it performs analysis and verification only. It is limited by the RPC provider's rate limits and block range availability for historical log queries. It cannot simulate shared sequencer consensus or rollup-specific ordering—the tool provides an on-chain view but cannot test the actual sequencing logic. The analysis relies on the accuracy and completeness of contract verification and sequencing event data; incomplete logs or unverified contracts may produce incomplete results. It cannot analyze contracts that are not verified or have opaque shared sequencing mechanisms where events are not emitted. The tool is limited to the specific shared sequencer contracts and events that are accessible via RPC. It cannot guarantee that integration patterns reflect actual shared sequencing behavior without manual review and cross-verification with rollup chain data. The tool does not validate the correctness of the cross-chain ordering logic—only that the contracts and events are present.
PLEASE NOTE
This is a read‑only analytics tool—it never submits transactions or triggers sequencing. It is designed for EVM‑compatible chains with shared sequencer contracts that emit sequencing and integration events. The integration test results are for informational and audit purposes only and should not be considered a comprehensive validation of shared sequencing correctness. Always manually test shared sequencing integration through actual cross-chain ordering and batch submission in a staging environment. The tool's status indicators are heuristic and based on the selected lookback period and observed patterns—customize thresholds based on your specific shared sequencer configuration and expected integration behavior.
