GetBlock, a blockchain node infrastructure provider, has unveiled a new layer of protection aimed at safeguarding decentralized applications from malicious transaction manipulation tactics. The company has introduced MEV-protected Remote Procedure Call (RPC) endpoints for four prominent blockchain networks—Ethereum, Solana, BNB Smart Chain (BSC), and Base—enhancing security for developers and users operating within these ecosystems.
Addressing the Threat of MEV Exploits
The move comes as concerns over Maximum Extractable Value (MEV) attacks continue to grow. MEV exploits, including frontrunning and sandwich attacks, often target transactions in the public mempool by reordering, inserting, or censoring them for profit. These tactics not only pose a risk to end-users but also burden developers with the need to implement their own in-app defenses.
GetBlock’s new service integrates MEV mitigation directly at the RPC layer. By doing so, it removes the necessity for dApp developers to build and maintain separate layers of protection. All users on GetBlock’s paid shared-node plans can access this enhanced security at no extra charge, while free-tier users are required to upgrade to benefit from the feature.
Partnering with Merkle for Private Mempool Protection
To implement this advanced level of protection, GetBlock has partnered with Merkle, a well-established provider of private mempool infrastructure. The collaboration allows GetBlock’s RPC gateway to route user transactions through Merkle’s private mempools and builder nodes rather than the public mempool, where MEV bots typically operate. Once inside this private network, transactions are bundled and processed securely, away from prying eyes and exploitative algorithms.
This architecture offers end-to-end protection from the moment a transaction is submitted. Developers simply choose the MEV-Protected endpoint available within GetBlock’s dashboard, and the system automatically activates the underlying Merkle protection protocols without requiring any changes to existing code.
Seamless Integration for Developers
GetBlock has emphasized that one of its key goals was to make the new functionality as seamless as possible for its users. The MEV-protected endpoints maintain the same familiar API specifications, ensuring developers can continue working with their usual tools and workflows while benefiting from the added security. This plug-and-play approach lowers the barrier to adoption and reduces the friction often associated with implementing advanced security measures.
Targeting High-Risk Networks First
The initial rollout focuses on networks considered particularly vulnerable to MEV-related activity. Ethereum and BNB Smart Chain, given their high transaction volume and DeFi activity, are frequent targets for MEV bots. Solana and Base also experience substantial network activity, making them suitable candidates for early implementation of the service.
Looking ahead, GetBlock is in the process of developing a dedicated MEV-protected solution tailored to the needs of high-throughput and institutional clients. This offering is expected to provide similar protections for those utilizing dedicated node infrastructure.
Strengthening Web3 Infrastructure
GetBlock’s leadership has expressed confidence that this enhancement represents a significant step toward a more secure and equitable blockchain environment. By embedding MEV protection at the infrastructure level, the company is working to create a safer experience for both developers and users across major blockchain ecosystems.
As MEV attacks become increasingly sophisticated, initiatives like this signal a growing trend in the Web3 space to embed security deeply into the core infrastructure, rather than treating it as an afterthought. GetBlock’s latest move aligns with that direction, providing developers with practical tools to combat one of the most persistent threats in decentralized finance today.
