STACKS_DEVNET

Pre-configured StacksNetwork object for a local devnet environment (e.g. Clarinet's local blockchain). Uses http://localhost:3999 as the default base URL.

---

Usage

import { STACKS_DEVNET } from '@stacks/network';

console.log(STACKS_DEVNET.client.baseUrl);
// 'http://localhost:3999'

Most @stacks/transactions functions accept a network string directly:

import { makeContractCall, Cl } from '@stacks/transactions';

const tx = await makeContractCall({
  contractAddress: 'ST1PQHQKV0RJXZFY1DGX8MNSNYVE3VGZJSRTPGZGM',
  contractName: 'my-contract',
  functionName: 'my-function',
  functionArgs: [Cl.uint(1)],
  senderKey: '753b7cc01a1a2e86221266a154af739463fce51219d97e4f856cd7200c3bd2a601',
  network: 'devnet', // equivalent to passing STACKS_DEVNET
});

Notes

• Devnet inherits all testnet settings (chain ID, transaction version, address versions) but uses different magic bytes (id) and a local API URL.

• Addresses on devnet use the same format as testnet (ST / SN).
