Waiting approximately 13 minutes for full finality is now a thing of the past. We are delighted to share that Ankr has officially integrated support for the Ethereum Fast Confirmation Rule, commonly referred to as FCR. Because of this integration, developers have the ability to retrieve fast-confirmed Ethereum blocks in a window of just 12 to 24 seconds.

This rapid turnaround time paves the way for a variety of performance improvements across your applications. Specifically, the accelerated speed facilitates swifter cross-chain messaging and enables indexers to access much fresher data. Furthermore, users will benefit directly from quicker exchange deposits and more rapid updates to their wallet balances.

These enhanced speeds are currently live and ready for use on both Sepolia and the Ethereum mainnet. The transition is completely seamless for developers, meaning there is absolutely no requirement for SDK upgrades or the configuration of new endpoints. We invite you to dive right in and begin building with these new capabilities today.
