Network and API library for working with Stacks blockchain nodes.

npm install @stacks/network

Creating a Stacks mainnet, testnet or mocknet network

import { StacksMainnet, StacksTestnet, StacksMocknet } from '@stacks/network';

const network = new StacksMainnet();

const testnet = new StacksTestnet();

const mocknet = new StacksMocknet();

Setting a custom node URL

const network = new StacksMainnet({ url: 'https://www.mystacksnode.com/' });

Check if network is mainnet

const isMainnet = network.isMainnet();

Example usage in transaction builder

import { makeSTXTokenTransfer } from '@stacks/transactions';

const txOptions = {
  network,
  recipient: 'SP2BS6HD7TN34V8Z5BNF8Q2AW3K8K2DPV4264CF26',
  amount: new BigNum(12345),
  senderKey: 'b244296d5907de9864c0b0d51f98a13c52890be0404e83f273144cd5b9960eed01',
};

const transaction = await makeSTXTokenTransfer(txOptions);

Get various API URLs

const txBroadcastUrl = network.getBroadcastApiUrl();

const feeEstimateUrl = network.getTransferFeeEstimateApiUrl();

const address = 'SP2BS6HD7TN34V8Z5BNF8Q2AW3K8K2DPV4264CF26';
const accountInfoUrl = network.getAccountApiUrl(address);

const contractName = 'hello_world';
const abiUrl = network.getAbiApiUrl(address, contractName);

const functionName = 'hello';
const readOnlyFunctionCallUrl = network.getReadOnlyFunctionCallApiUrl(
  address,
  contractName,
  functionName
);

const nodeInfoUrl = network.getInfoUrl();

const blockTimeUrl = network.getBlockTimeInfoUrl();

const poxInfoUrl = network.getPoxInfoUrl();
