Base Blockchain Upgrade Removes Flashblocks Feeds
Base, the blockchain layer for Coinbase Wallet, has upgraded its Denim protocol, removing its Flashblocks data feeds. Apps previously using Flashblocks can still connect to the network, but they will not receive any data. Developers must now switch to block updates from a compatible provider or their own node to continue receiving information. The upgrade, which took place on November 5, ensures that apps are receiving the latest canonical blocks, each with its own hash, state root, and receipts. The transition is necessary due to the change in how the blockchain handles pending transactions and balances.
