Flash Minibuilder Info

Use Go or Rust to create an RPC server that accepts eth_sendBundle requests but does not propagate them to the public mempool.

Like the high-frequency trading (HFT) cables that run under the Atlantic Ocean, flash minibuilders are invisible yet essential. They ensure that when you click "swap" on your favorite DEX, the price is fair, the liquidation happens on time, and the blockchain remains solvent. flash minibuilder

Enter the . This emerging piece of middleware infrastructure is quietly rewriting the rules of how blocks are built and submitted. While most users are focused on Layer 2 rollups and faster consensus mechanisms, the Flash Minibuilder is optimizing the final, crucial mile of transaction inclusion. What Exactly is a Flash Minibuilder? To understand a Flash Minibuilder, you must first understand the traditional block building pipeline. Typically, a blockchain (like Ethereum) has a mempool where pending user transactions sit. Block builders scan these transactions, select the most profitable ones (usually those paying the highest gas fees), and assemble them into a block. That block is then proposed to the network. Use Go or Rust to create an RPC

As blockchains evolve from toy networks to global settlement layers, the race is no longer about blocks per second. It is about . And the Flash Minibuilder is leading that race. Enter the
