Blockfrost

Blockfrost.io (opens in a new tab) is a service that serves as an access to the Cardano blockchain and related networks without the need for running and maintaining additional infrastructure and tooling yourself.

Usage example to initialize Lucid with Blockfrost:

import { Lucid, Blockfrost } from "@lucid-evolution/lucid";
 
const lucid = await Lucid(
  new Blockfrost("https://cardano-preprod.blockfrost.io/api/v0", "<blockfrost-api-key>"),
  "Preprod"
);
