Infura

Infura is a blockchain node infrastructure and API provider that gives developers remote access to the Ethereum network and other decentralized protocols without requiring them to run their own nodes. Founded in 2016 and acquired by Consensys in 2019, Infura is headquartered in the United States and operates as part of the Consensys group, which also develops MetaMask.

The platform offers high-availability JSON-RPC endpoints, an IPFS API and gateway, and a suite of developer tools aimed at teams building decentralized applications. Supported networks include Ethereum, Polygon, Arbitrum, Optimism, Avalanche, Linea, StarkNet, ZKsync, and several other Layer 1 and Layer 2 chains. A free tier is available alongside paid plans for higher request volumes.

Infura is used by developers across decentralized finance, NFTs, and Web3 infrastructure. The company is also developing a Decentralized Infrastructure Network (DIN) intended to reduce single points of failure in the RPC layer by distributing node access across multiple providers.
