Infura is a node-as-a-service: it runs full Ethereum nodes so that its users do not have to sync one themselves. Its API key authenticates and rate-limits usage, and plays no part in the cryptographic security of transactions.

Infura is a node-as-a-service: it runs full Ethereum nodes so that its users do not have to sync one themselves. Its API key authenticates and rate-limits usage, and plays no part in the cryptographic security of transactions.

Infura acts as a gateway: it receives a transaction already signed (ECDSA), so it never touches the user's private key, and relays it to its fleet of nodes, which gossip it to the network.
