MEV Services

Builder Wallet

For MEV bundle submissions and transaction ordering:

Builder Address: 0xe89c42BC188c993273Ab34231e12ae60c73042E4

Important: To ensure successful bundle inclusion, transfer funds directly to the builder wallet. Do not use gasPrice modifications as they may interfere with our MEV optimization algorithms.

Common Error Responses

HTTP 400 Bad Request

Possible Causes: - Using maxBlockNumber parameter instead of blockNumber - Incorrect parameter format (e.g., string instead of number for id field)

Solutions: - Ensure blockNumber is used for single block queries - Verify all numeric parameters are passed as numbers, not strings - Check parameter naming conventions in our API documentation
