FastNEAR API

FastNEAR provides high-performance infrastructure enabling seamless blockchain interactions.

Overview

FastNEAR exposes low-latency APIs for wallets and explorers. Their API allows you to easily query the NEAR blockchain to get an account's assets, map keys into account IDs, explore a block's transactions, etc.

More info

Find more information about the FastNear API in their services page.

RPC implementation

Fast-Near aims to provide the fastest RPC implementation for NEAR Protocol using high-performance storage backends:

• in-memory storage in Redis.
• SSD optimized storage using LMDB.

It is optimized for view call performance and ease of deploy and scaling.

About data sync

FastNear doesn't sync with the NEAR blockchain on its own. Data needs to be loaded either from NEAR Lake or from Near State Indexer.
