Relayers, bundlers, and paymasters

Transaction relayers, such as Gelato, enable projects and users to bypass the complexities of onchain transaction submission and gas management. These relayers facilitate transaction submissions on behalf of the projects and users according to predetermined preferences.

By using MEV Blocker, transaction relayers can guarantee their transactions are free from MEV, and can even capture value in cases where backrunning opportunities are present.

Integrate MEV Blocker

MEV Blocker is fully permissionless and mirrors the standard Ethereum RPC spec: no special setup or code changes are needed. You can start using our endpoints right away—no signup, no gatekeeping.

MEV Blocker was built for effortless integration—just switch your app or wallet's RPC endpoint and you're good to go.

Integration steps

1. Choose your endpoint: decide which MEV Blocker endpoint suits your use case best.

2. (Optional) Customize your setup: set a custom beneficiary address to receive rebates.

3. Swap Your RPC URL: update your current RPC endpoint to:

Nonce management

important

Transactions sent through MEV Blocker's private mempool won't appear in the public mempool's nonce count. Query MEV Blocker's eth_getTransactionCount method with "pending" accounts for your private transactions, to ensure that you get the correct next nonce.
