Base Denim goes live on mainnet with Alchemy ready

Base Denim is live on mainnet, cutting block times from 2 seconds to 200 milliseconds — five blocks per second — alongside BaseTime for millisecond precision and B20 improvements. Base announced the activation on X on November 5, and Alchemy reposted it, saying it is "seeing massive growth already" and noting that Base is its #2 most popular chain.

Alchemy says it got ready ahead of the upgrade: it deployed Denim on Base Sepolia on October 21 as soon as it was available, weeks before mainnet activation.

• Alchemy helped builders migrate off Flashblocks to the new native block cadence, tuned its gasless transaction infrastructure and data APIs for faster blocks, and scaled Base mainnet RPC and WebSocket infrastructure ahead of the usage increase
