Pool State & Indexing Guide

What data to index and how to keep simulations accurate

Overview

To simulate swaps or monitor execution availability, integrators must index a minimal set of on-chain state from Bolt Outposts.

This page describes:

• Which pool variables matter

• How often state should be refreshed

• How to reason about inventory availability

Core State to Index

Typical state includes:

• Available inventory per asset

• Pool thresholds and minimum balances

• Fee parameters

• Oracle reference identifiers

Exact field names and schemas are chain-specific.

Indexing Strategy

• Poll or subscribe to Outpost state updates

• Refresh state frequently enough to avoid stale quotes

• Treat inventory availability as the primary execution constraint

Execution Availability

Unlike AMMs:

• Pool depth does not affect price

• Inventory availability determines fill success

• Quotes should be rejected if inventory is insufficient

This makes Bolt particularly suitable for deterministic routing.
