Indexer Gateway

The Sequence Indexer Gateway API is a powerful tool for simultaneously performing queries across multiple chains. By Leveraging Indexer, the Indexer Gateway allows you to find and filter data across the Ethereum chains we support.

The API is not only modeled after Indexer, it actually uses Indexer behind the scenes, so you can take your code that already works with Indexer and make it multi-chain with just a few modifications.

Supported Networks & Endpoints

The Indexer Gateway endpoints accept a list of network IDs (e.g.: [1, 137, 10]) or a list of network names (e.g.: ["mainnet", "polygon", "optimism"]).

You can see the full list of supported networks here.

Getting Started

Here are a few example queries you can make to multiple networks from your dapp, game, or wallet:

• Fetch tokens & NFTS in any wallet across all chains, including metadata

• Fetch native balances across all chains

• Fetch balance updates across all chains

• Fetch tokens with advanced filters

• Fetch tokens, by contract, with advanced filters
