Fireblocks’ New Developer APIs: Build on Blockchain Without Complexity

Blockchain innovation is accelerating, offering new opportunities for developers to create secure applications. However, integrating blockchain infrastructure is getting increasingly complex. With more fragmentation, developers often have to juggle multiple tools, workarounds, and technical intricacies to manage…

Helping builders develop and deploy faster

- Easy-to-use API references
  
  Leverage robust REST APIs to programmatically launch new products on Fireblocks' capabilities. Explore our APIs via OpenAPI 3.0 (Swagger) or using Postman.
  API Overview
- Versatile SDKs
  
  Get started with the SDK you need. Use pre-built components and API libraries to create applications for a variety of use cases.
  SDKs and Dev Tools
- Event-driven developer webhooks
  
  Get real-time notifications for events happening within your Fireblocks workspace and ensure that all relevant event types are broadcasted to your designated endpoint.
  Configure webhooks

import { Fireblocks, BasePath } from "@fireblocks/ts-sdk";
import fs from "fs";
import path from "path";

const secretKey = fs
    .readFileSync(path.resolve(__dirname, "fireblocks_secret.key"), "utf8")
    .split(String.raw`\n`)
    .join("\n");

const fireblocks = new Fireblocks({ secretKey, apiKey:'api-key', basePath:BasePath.US });

//create vault
await fireblocks.vaults.createVaultAccount({ createVaultAccountRequest: { name: "QuickStartVaultAccount" } });

//create tx
await fireblocks.transactions.createTransaction({
    transactionRequest: {
        assetId: "BTC",
        source: { id: "1", type: "VAULT_ACCOUNT" },
        destination: { id: "2", type: "VAULT_ACCOUNT" },
        amount: 1
    }
});
