Getting Started as a Searcher

How to get started as a FastLane Searcher on Polygon

This guide will help you get started as a FastLane Searcher on Polygon. To integrate with the FastLane protocol, you need to make two key changes to your system:

Note: The terms "Searcher" and "Solver" are used interchangeably throughout this document.

1. Configure Your Backend for Auction Bidding:

• Set up your backend to create and send bids to FastLane auctions.

• Note: FastLane now supports only one type of auction:

  • Searcher Bundles (Backrun Auctions): Participate by submitting bundles

• Bids are submitted via EIP-712 signed messages (Solver Operations)

Bids are sent to the FastLane Relay API via various submission methods.

2. Implement theISolverContract Interface

• Your contract must implement the ISolverContract interface, which defines the required atlasSolverCall function

• This function allows the FastLane Atlas protocol to interact with your contract for bid execution and operation handling.
