Searcher

Introduction

Searcher can subscribe bundles on Scutum to execute the backrun strategy, and then send the backrun bundles to Scutum to obtain backrun benefits.

In addition, Searcher can also skip bundle subscription and send the raw bundle directly to Scutum. With the network acceleration service of high-performance network, Scutum can forward the bundle to mainstream builders (Ethereum and BSC) with extremely low latency.

Bundle Flow

bundle flow

Raw Bundle: The hash field is empty, which means there is no backrun object. The txs in the bundle come from the public mempool or are self-constructed, and up to 50 rawtransactions can be set. Searchers can authorize the disclosure of txs in raw bundles to allow other Searchers to backrun, or they can keep transactions private and Scutum will forward the raw bundles to mainstream builders.

Backrun Bundle: Searcher executes the backrun strategy on the raw bundle to form a backrun bundle. The hash field sets the raw bundle hash received in the data stream, and txs field sets the backrun tx. Searchers can disclose the backrun bundle to other Searchers to execute nested backrun strategy. The overall structure of the backrun bundle in the data stream is generally [raw bundle txs…, backrun tx].

FAQ

What is the difference between sending Bundle to Scutum and MEV services?

• Scutum supports Ethereum and BSC, MEV service currently only supports BSC

• In BSC, Scutum will forward the bundle to mainstream builders, and the MEV service will send the bundle to BlockRazor Builder

• Scutum is currently available without subscribing plan. Advanced features of the MEV service (such as 0gwei) require subscribing plan.
