In May 2025, GetBlock began offering MEV-protected RPC endpoints on shared nodes for four major protocols. We also streamlined our authorization and billing systems laying the foundation for seamless expansion into new regions.
This month’s edition of the GetBlock Dev Update arrived a bit later than usual, as our team was fully engaged with several major conferences. We truly appreciate your patience and continued support!
All about MEV: Protected RPC endpoints on shared nodes
The release of MEV-protected endpoints is the highlight of our May 2025 updates. GetBlock now offers transaction protection for users of shared nodes across Ethereum, BNB Smart Chain, Base, and Solana.
GetBlock is among the first RPC node providers to deliver MEV protection at the node level. No additional in-app configuration is needed: users simply log into GetBlock, activate a paid subscription, and access MEV-protected shared node endpoints.
Once connected, user transactions are routed to a private mempool instead of the public one. This MEV protection is made possible through our collaboration with Merkle, a pioneer in private mempool services.
Advanced authorization scheme: Faster account response
In May, we rolled out a new authorization scheme designed to reduce latency through optimized data logistics. The key improvement was switching to in-memory caching of user configurations based on the access token used by each user.
Previously, configurations were retrieved from Redis using the access token. In the new version, lookups are performed directly in memory within the service itself.
Following this update, we observed a significant reduction in latency and a drop in HTTP 408 status code errors to just 0.001%.
Enhanced bot protection: Smoother access, fewer checks
We also reworked our bot protection mechanisms, implementing several important updates related to Cloudflare Turnstile:
- Turnstile tokens were removed from the user dashboard. This means faster requests in the personal account area, as no token validation is performed there.
- The Turnstile widget now appears in cases of false positives. If a legitimate user is mistakenly flagged as a bot, they’ll see the widget and have the chance to verify themselves.
These changes resulted in improved performance within the personal dashboard and a better overall user experience when bot detection triggers incorrectly.
Asynchronous withdrawal design: Faster requests handling
As part of our roadmap to support new regions, we optimized the internal “withdrawals” design. Specifically, the accounting scheme that tracks user balances is re-written.
With the May 2025 upgrade, GetBlock transitioned Bookkeeper - our internal accounting tool for user balances - to an asynchronous mode. This means user requests no longer wait for balance deductions to complete. Instead, they are sent to the node immediately, while balance updates happen in parallel.
This upgrade once again delivers reduced latency and improved performance for users across various regions.
Node clients updates
The GetBlock team continues to update our node software clients to ensure all customers are interacting with nodes using the latest implementations. Here are the three major updates we rolled out in May:
Ethereum Pectra
The Ethereum Pectra upgrade—the most ambitious EVM hard fork since The Merge in 2022—redefines the validation process, enhances Ethereum blob performance, and improves overall efficiency for both Ethereum L1 and associated L2 networks.
OP Stack: Isthmus
The Optimism Isthmus upgrade ensures that OP Stack chains remain aligned with Ethereum Mainnet after Pectra. It brings immediate cost-efficiency gains of approximately 40% for Optimism and its ecosystem chains.
Wrapping up: New regions taking shape
Looking ahead to June 2025, our focus will shift to upcoming conferences - ETH Belgrade and DappCon Berlin -and the next phase of expanding shared node infrastructure. New node clusters will soon be available in the U.S. and Asia, significantly improving latency and access in those regions.
Stay safe, and thank you for building with us.
Best regards,
The GetBlock Team
