Blast API

Blast API is a decentralized Web3 infrastructure platform that solves blockchain reliability and performance issues by efficiently employing resources from hundreds of third-party node providers. The platform offers high-performance RPC endpoints across 30+ blockchain networks including Ethereum, BNB Chain, Avalanche, Polygon, Arbitrum, Optimism, Starknet, Aptos, Sui, and many others.

Key Features

Public API Access: Developers can access the industry's fastest and most reliable API offering to kickstart their blockchain development journey with free public endpoints.

Dedicated Endpoints: Users can create custom projects and generate dedicated endpoints for any supported blockchain network with dedicated support, custom SLAs, and volume discounts for enterprise customers.

Blast SDK: Developer SDK designed to offer builders an improved development experience and more efficient blockchain interactions by eliminating hurdles involved in using blockchain endpoints.

Proof of Quality Protocol: The platform implements a unique Proof of Quality concept that ensures access to high-performance blockchain infrastructure in a decentralized manner through integrity and staking protocols.

Fast Node Synchronization: Pre-synchronized blockchain state snapshots allow for rapid node deployment and testing, reducing node setup time from days or weeks to just hours.

App Chain Support: Dedicated RPC endpoints for custom Avalanche Subnets and Polygon Supernets, with custom plan benefits and request tracking for optimized cost and improved experience.

Supported Networks

The platform supports 30+ chains across Layer 1 (Ethereum, BNB Chain, Avalanche, Fantom, Aptos, Sui), Layer 2 (Polygon, Arbitrum, Optimism, Base, Scroll, zkSync, Linea, Metis), Parachain ecosystems (Moonbeam, Moonriver, Astar, Shiden), and specialized networks (Starknet, MultiversX, Evmos, Palm, Mantle, Mode, CrossFi).

Use Cases

Ideal for Web3 developers building dApps, DeFi protocols, NFT platforms, blockchain explorers, wallets, and any application requiring reliable RPC access across multiple chains. Enterprise customers benefit from custom SLAs, dedicated support, and volume-based pricing. Essential for node operators setting up new validator infrastructure, developers building and testing blockchain applications, infrastructure providers needing quick node deployment, and projects requiring rapid network synchronization for archival or indexing purposes.
