MEV-Boost Relayer Manager

WHAT IT DOES

MEV-Boost Relayer Manager gives Ethereum validators and staking operators full control over MEV-Boost relay configuration and management. It reads live on-chain and off-chain data including MEV-Boost relay status, registered relayers, bid information, block proposals, validator registration data, and relay performance metrics. You can register new relays, update relay configurations, submit validator registrations, query active bids, and monitor relay health. The tool shows you in real time whether relays are active, how many bids are pending, whether validators are registered, and the last block processed—so you can optimize your MEV-Boost setup and maximize validator returns.

HOW TO USE

Connect your EVM wallet (must be the contract owner or authorized address). Enter the relayer contract address, relay endpoint URL, validator public key, and fee recipient address. Use "Check relay status" to see active status, last block, active bids, and validator registration status. Click "Register relay" to add a new relay endpoint. Use "Register validator" to register a validator with a fee recipient. "Update config" updates the relay endpoint and fee recipient settings. "Query bids" shows current active bids from the relay. Each action generates a transaction you review and sign in your wallet.

TECHNICAL APPROACH

This tool interacts with MEV-Boost relayer contracts using ethers v5.7.2. It calls registerRelay(), registerValidator(), updateConfig(), getRelayStatus(), getActiveBids(), and isValidatorRegistered() on the relayer contract to manage and query relay state. The tool validates endpoint URLs, public keys, and addresses before submission. It checks relay status by reading active state and last block number from the contract. For validator registration, it submits the public key and fee recipient address to the contract. All RPC calls are wrapped in a robust error handler that extracts the actual failure reason from Ethers error objects, digging three levels deep to avoid showing "[object Object]" when a transaction reverts. Transaction costing uses receipt.effectiveGasPrice post-EIP-1559 rather than tx.gasPrice, which overstates actual spend.

WHAT IT CANNOT SEE

This tool cannot guarantee relay availability or performance. It cannot detect off-chain relay collusion or malicious relay behavior. It cannot verify that a relay endpoint is actually operational or honest. It cannot simulate block proposals or predict which relay will provide the best bid. It cannot see relay internal decision-making or bid selection criteria. It cannot detect whether a relay is censoring transactions or manipulating bids. The tool manages relay configurations and registrations, but it does not guarantee that relays will behave honestly or that validators will receive optimal bids.

PLEASE NOTE

This tool supports EVM‑compatible chains only (Ethereum, Goerli, Sepolia, Arbitrum, Optimism, Polygon). MEV-Boost is primarily used on Ethereum Mainnet and testnets. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. This is a read‑write tool that requires signing transactions—always verify the relayer contract address, endpoint URL, public key, and fee recipient before approving. No contract addresses are hardcoded; you paste the contracts you are managing. The tool is free and open under the BotGentz PLAYBOOK‑C specification.
