API Endpoints

  • API status

    • Tesnet: https://api.testnet.hiro.so/extended/

    • Mainnet: https://api.hiro.so/extended/

  • Burn Block endpoint. This will allow you to get the hashes of fast Stacks blocks as they are added to the chain and see their associated burn blocks.

    • Testnet: https://api.testnet.hiro.so/extended/v2/burn-blocks

    • Mainnet: https://api.hiro.so/extended/v2/burn-blocks

  • Pox endpoint. This allows you to get information about proof of transfer, including the currently deployed pox-4 contract. This will be helpful for anyone looking to incorporate stacking into their app.

    • Testnet: https://api.testnet.hiro.so/v2/pox

    • Mainnet: https://api.hiro.so/v2/pox

Local Development Environment

Clarinet has been updated to work with Nakamoto as of version 2.4. That means you can use Clarinet to build locally using Nakamoto rules in your local development environment and use Clarinet and deployment plans to deploy to Nakamoto Testnet.

Be sure to update Clarinet to the newest version: https://docs.hiro.so/clarinet/getting-started
