HyperSync
Blockchain data API built in Rust as a faster alternative to JSON-RPC.
Overview
HyperSync is Envio's data retrieval layer for onchain data, written in Rust. It replaces JSON-RPC for read-heavy work. One query can filter by contract, event topic, and block range, and return only the fields you ask for. On Envio's published benchmarks, historical scans that take hours or days over RPC finish in seconds.
Developers use it for indexers, analytics, block explorers, monitoring tools, and ETL pipelines. Client libraries are available for Node.js, Python, Rust, and Go, and there is a visual query builder at builder.hypersync.xyz. Requests need an API token, which you can create in the Envio dashboard.
HyperSync supports EVM chains and Fuel, with new networks added regularly, and is the data engine behind HyperIndex, Envio's indexing framework. The full list is at docs.envio.dev/docs/HyperSync/hypersync-supported-networks.
