Goldsky: Real-Time Blockchain Indexing and Data Streaming for Web3

Quick Overview

Goldsky is a fast indexing platform that provides developers with real time blockchain data using subgraphs edge RPC and data streaming pipelines to power modern Web3 applications and onchain finance.

About Goldsky

What is Goldsky?

Goldsky is a fast and powerful indexing platform that provides real-time blockchain data for crypto businesses and onchain finance. Instead of building complex server infrastructure, developers use Goldsky to read, write, and process smart contract events easily. The system is extremely fast, handling over 100 million events every minute with less than one second of delay.

The platform offers three main tools for building the backend of Web3 projects. It provides Subgraphs for searching specific onchain data using a GraphQL API, Edge RPC for direct global connection to blockchain nodes, and data streaming pipelines that send live smart contract events straight into your own database. It currently supports more than 150 different networks, including huge ecosystems like Ethereum, Solana, Polygon, Optimism, and Base.

Who is it for?

Goldsky is designed for developers, data engineers, and companies building modern Web3 applications. It is easy enough for a beginner creating a weekend crypto project, but strong enough to support large enterprise systems that manage billions in total value locked (TVL).

Digital Wallets and Payments: Developers use the platform to index user transaction history, track live token balances, and quickly verify complex onchain payments.
DeFi and Trading Apps: Decentralized finance (DeFi) teams rely on the speed to monitor liquidity pools, calculate active trading volumes, and watch token yields in real time.
Stablecoin Issuers: Financial companies use it to track real reserve asset backing, monitor stablecoin minting, and ensure the price peg remains stable.
Prediction Markets and Gaming: Fast platforms use the data to calculate live betting odds, trace in-game player items, and update live game states on the blockchain.

How it works?

Goldsky works by operating as a high-speed data bridge between raw blockchain networks and our application front-end. It actively listens to new blocks and specific smart contract activity across the globe, processing that raw data into a readable format.

You can connect your application to this data in three simple ways depending on your exact workflow:

Custom API Endpoints: You can deploy an indexer in minutes. Goldsky reads the heavy blockchain history and creates a personal GraphQL API endpoint. Your app simply queries this API to show users their data instantly without waiting.
Live Data Streaming: If you need data in your own system, you can build a streaming pipeline. Goldsky will grab live blockchain events, format them cleanly, and push them straight into your own analytics database, like Postgres or ClickHouse.
Global Edge Network: When your app needs to write a new transaction or request current state blocks, it sends the command through Goldsky's fail-proof RPC endpoints. The network automatically finds the fastest server node to make sure your transaction never fails.
