Flashblock Stream
BlockRazor FlashBlock Stream delivers Base sub-block updates over gRPC or WebSocket before standard blocks are formed.
About this tool
The Get FlashBlockStream interface exposes Base FlashBlock data, a sequence of pre-confirmation sub-block updates that provides transaction and block-change signals earlier in the block-building cycle than a completed block stream.
It is intended for Base trading bots, quantitative strategies, real-time monitoring platforms, and trading front ends that need early on-chain awareness and can consume either gRPC or WebSocket feeds.
