Flashbots Bundle Construction

Flashbots bundle construction is the process of grouping multiple transactions into a single unit to be submitted directly to block builders. This technique allows participants to express complex preferences, such as ensuring that their trade is executed only if it results in a profit.

By using a bundle, the searcher can specify the order of transactions, effectively preventing other bots from interfering. It also allows for the payment of bribes or tips to validators to guarantee inclusion.

This process is designed to minimize the negative externalities of MEV on the public mempool by keeping competitive bidding off-chain. It has become a standard practice for managing high-value trades and protecting against front running.

The construction of these bundles requires precise knowledge of the target blockchain state and smart contract behavior.
