Blaze

Blaze is a library, which allows you to create Cardano transactions and off-chain code for your Aiken contracts in JavaScript.

Built with ❤️ by the Butane Team.

Get started

This api is experimental!

Installation

npm i @blaze-cardano/sdk
Copy

Basic Usage

//  In this example we:
//  - prepare the provider (Maestro), wallet, blaze,
//  - build a transaction paying out 5 ada to an external wallet
//  - dump the transaction cbor
import { ColdWallet, Core, Blaze, Maestro } from "@blaze-cardano/sdk";
import * as readline from "node:readline/promises";
import { stdin, stdout } from "node:process";
const rl = readline.createInterface({ input: stdin, output: stdout });

await setTimeout(() => {}, 1000);

let address = Core.addressFromBech32(
  await rl.question("Please enter your bech32 cardano address: "),
);

// $butane wallet can collect donations for us
const blazeWallet = Core.addressFromBech32(
  "addr1qye93uefq8r6ezk0kzq443u9zht7ylu5nelvw8eracd200ylzvhpxn9c4g2fyxe5rlmn6z5qmm3dtjqfjn2vvy58l88szlpjw4",
);

const provider = new Maestro({
  network: "mainnet",
  apiKey: await rl.question("Please enter your mainnet maestro key: "),
});
const wallet = new ColdWallet(address, 0, provider);

console.log("Your blaze address: ", wallet.address.toBech32());
const blaze = await Blaze.from(provider, wallet);

//Use the awesome transaction builder
const tx = await blaze
  .newTransaction()
  .payLovelace(blazeWallet, 5n * 1_000_000n)
  .complete();

// Dump the transaction for you to submit securely
console.log(`Please sign and submit this transaction: ${tx.toCbor()}`);
