When it comes to building trust in decentralized applications, nothing kills momentum faster than sneaky MEV bots front-running, sandwiching, or extracting hidden value from users’ transactions.
Today, GetBlock is changing the game, rolling out fully MEV-protected RPC nodes, focusing on Solana, Ethereum, BNB Smart Chain, and Base. The result is the same familiar RPC workflow, but with an invisible shield against the most sophisticated on-chain predators.
Why MEV protection matters
Maximum Extractable Value (MEV) describes the profit MEV seekers can skim off every swap, NFT mint, or auction by censoring, front-running, or sandwiching transactions in the public mempool. That extra cost comes straight out of your users’ pockets and can result in higher slippage, failed transactions, or simply a worse UX overall.
For dApp developers, MEV isn’t just a backend headache, it’s a direct hit to user experience and trust. By embedding protection at the RPC layer, GetBlock ensures that users’ transactions land on-chain exactly as intended, without exposing them to predatory actors.
Under the hood: Private mempools with Merkle
Traditional defenses against MEV often involve custom middleware or other extra layers that increase the maintenance burden. GetBlock handles the protection at the network-access layer, thanks to its collaboration with Merkle.
Via this integration, transactions submitted to GetBlock’s protected endpoints are first routed through Merkle-managed private mempools:
- Public MEV bots never see pending transactions, so they can’t sandwich or re-order them.
- Merkle assembles the block privately, then delivers it to the network, no value extraction, guaranteed.
How to get an MEV-protected endpoint
For GetBlock clients on any paid shared-node tier, MEV protection is included at no extra configuration cost. To enable MEV protection on GetBlock:
- Sign in to your user account at getblock.io.
- Navigate to the Shared Nodes dashboard.
- Pick one of the mainnets: Ethereum, Base, BSC, or Solana.
- Toggle on the “MEV-Protected” option while configuring the API.
- Generate the RPC URL to use in your dApp or service.

Once you’ve completed these steps, every JSON-RPC request your application makes to that URL is automatically funneled through Merkle’s secure mempools. No additional development effort required – the protection is embedded into the endpoint itself.
Free-plan accounts do not include MEV protection by default, but upgrading is quick and painless.
