"It doesn't just copy-paste a folder," explains the project’s lead maintainer. "It builds the file tree in memory, checks for the latest stable versions of dependencies, and injects only the code required for the specific features the user requested. If you don't need a router, you don't get a router. If you don't need a database connection, you don't get an ORM driver." "It builds the file tree in memory, checks
Conceptually, the Flash Minibuilder sits between the Searcher and the Relay. In the traditional PBS model, a searcher sends a bundle to a builder, hoping it gets included. In the minibuilder model, the searcher is the builder, or the minibuilder is a custom API endpoint specifically for that searcher’s optimized code. In the traditional PBS model, a searcher sends
Standard builders simulate every transaction to ensure it doesn't revert. A flash minibuilder trusts the searcher’s signature or uses a local, pre-cached state root. Instead of re-simulating the user’s complex arbitrage loop, the minibuilder assumes the bundle is valid (backed by a bond or reputation system) and simulates only the final state change.
