MEV-Share Bundle Construction Tool

WHAT IT DOES

MEV-Share Bundle Construction Tool provides comprehensive bundle construction for MEV-Share protocols, enabling searchers, builders, and DeFi participants to construct and optimize MEV bundles with privacy and refund mechanics. It retrieves on-chain transaction pool and mempool data via RPC, processes bundle construction specifications according to the MEV-Share protocol, and analyzes transaction data and calldata. The tool constructs bundles by selecting transactions from the mempool, ordering them for optimal MEV extraction, and applying MEV-Share-specific parameters such as refund addresses, refund percentages, privacy settings, and block deadlines. The output includes a bundle status (Constructed, Pending, or Failed), count of transactions included, estimated MEV value, a detailed transaction matrix showing each transaction's hash and status (included, pending, or dropped), and actionable recommendations for optimizing bundle construction—such as adjusting transaction ordering, modifying refund parameters, or updating privacy settings. This enables MEV searchers and builders to construct MEV-Share bundles efficiently while respecting privacy requirements and refund obligations.

HOW TO USE

Connect your BGWallet to the target EVM chain. Provide the bundle specification as a JSON object containing transactions array, priority fees, block deadline, refund address, and refund percentage. Provide mempool data as a JSON object containing pending transactions, base fee, and gas prices. Optionally supply a GitHub repository URL to pull MEV-Share implementation details and bundle construction specifications for additional context. The tool analyzes the bundle specification and mempool data to construct an optimal bundle. Review the bundle status, transaction count, estimated MEV value, the transaction matrix showing individual transaction statuses, and the list of recommendations. Use the results to refine your bundle construction strategy and improve MEV extraction efficiency.

MEV-SHARE BUNDLE CONSTRUCTION AND OPTIMIZATION ENGINE

The real technical mechanism is the MEV-Share bundle construction and optimization engine that combines mempool analysis with MEV-Share protocol semantics. The tool first retrieves mempool data to identify pending transactions and their gas prices, then analyzes the bundle specification to understand the searcher's intent—including which transactions to include, the desired ordering, and the refund parameters. The engine constructs the bundle by ordering transactions to maximize MEV value while respecting the MEV-Share protocol's privacy and refund rules. It applies refund parameters by calculating the appropriate refund amounts to return to users whose transactions were included in the bundle, ensuring compliance with the MEV-Share protocol's fairness requirements. The engine also considers block deadlines and priority fees to maximize the probability of bundle inclusion. The transaction status matrix provides a clear view of which transactions were successfully included in the bundle and which were dropped or are pending. This approach provides MEV searchers and builders with a comprehensive, automated way to construct MEV-Share bundles, catching issues that would otherwise only surface during live bundle submission and improving MEV extraction efficiency while maintaining protocol compliance.

WHAT IT CANNOT SEE

This tool cannot generate a complete bundle construction without access to mempool data or transaction pool state. It is limited by your RPC provider's rate limits for data retrieval, which may delay analysis on congested networks. It cannot determine if bundles are correctly constructed without executing bundle construction logic—the tool provides construction simulations, not guaranteed outcomes. The detection relies on the completeness of the transaction data and mempool state; incomplete or stale mempool data will produce incomplete or inaccurate results. Detection is based on pattern matching and may miss indirect or obfuscated construction logic, such as construction logic hidden in libraries or via delegate calls. The tool cannot assess runtime behavior or performance implications of bundle construction, such as how bundle construction efficiency varies with mempool conditions or network congestion. It may produce false positives for data that appears similar to bundle data but is used for other purposes. The tool does not execute the contract to validate bundle construction, so it cannot confirm that the constructed bundle would be valid on-chain. It cannot account for network-specific MEV-Share implementation differences or future upgrades—different networks may have different MEV-Share implementations or bundle formats. MEV-Share bundle construction mechanics may vary across networks and change over time as protocols evolve.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains that support MEV-Share protocols. It requires active internet connectivity to access RPC endpoints and mempool data. Some RPC providers may require API keys for high-volume data retrieval. The tool is read-only and does not submit any bundles—it only produces construction assessments. MEV-Share bundle construction is critical to MEV extraction efficiency and fairness; always verify construction results against actual bundle submission behavior on testnet before mainnet deployment. Different MEV-Share implementations may have different bundle formats, refund rules, and privacy parameters.
