About Hiro

Suite of APIs and tools for building on Bitcoin, Stacks & Ordinals

Hiro is a powerful development platform focused on simplifying and scaling app creation on Bitcoin layers, especially through Stacks and Ordinals. With Bitcoin’s limitations in programmability, Hiro provides essential tools that bridge the gap—enabling developers to build smart contracts, query data, automate triggers, and more using a robust suite of APIs and developer services.


The platform is equipped with production-ready APIs, a real-time event system (Chainhooks), devnet environments, and a contract monitoring toolkit—all aimed at transforming the way developers build on Bitcoin. Hiro’s commitment to developer experience makes it a go-to choice for those creating secure, performant, and scalable Web3 applications anchored to Bitcoin’s security model.

Hiro offers an integrated suite of tools for building applications on Bitcoin layers, primarily supporting Stacks and Ordinals. Its product offerings include Clarinet for local smart contract development, Chainhooks for onchain event automation, and APIs for interacting with BRC-20, Runes, and Bitcoin addresses. The platform is designed to remove the complexity of building on Bitcoin by offering simple abstractions that drastically reduce development friction.


With tools like the Stacks Explorer, developers can validate Bitcoin finality for Stacks-based transactions, improving confidence in the long-term security of assets. Additionally, the Hiro Platform allows developers to deploy fullstack apps in minutes using prebuilt templates or GitHub imports, all while monitoring and debugging live smart contract activity from a unified dashboard.


Hiro sits in a niche but increasingly important space—enabling programmability on Bitcoin. Competing platforms like Trustless Computer and BitVM also explore programmability on Bitcoin, but Hiro leads with its mature tooling and developer-centric infrastructure. Its focus on developer velocity and full product integration offers a smoother and faster build experience compared to fragmented toolkits offered by competitors.


As Bitcoin continues to evolve beyond a store of value, Hiro is positioning itself as the central tool stack for developers seeking to unlock the full potential of Bitcoin-backed Web3 applications. From DeFi to NFTs to full-on dApps, Hiro enables development that is both efficient and secure.

Hiro provides numerous benefits and features that streamline development across Bitcoin layers:


  • Integrated Development Environment: Build, test, and deploy Clarity smart contracts using Clarinet and view all actions within one dashboard.
  • Production-Ready APIs: Access detailed blockchain data from Stacks, Ordinals, and Bitcoin through reliable, well-documented APIs.
  • Chainhooks Automation: Automate actions using IFTTT-style triggers for onchain events across both Stacks and Bitcoin.
  • Custom Deployments: Create repeatable and predictable smart contract deployment plans, especially useful for app scalability.
  • Monitoring & Alerts: Configure real-time monitoring of smart contracts and receive alerts on critical actions or admin calls.

Hiro FAQ

  • Hiro simplifies Bitcoin development by offering prebuilt templates, real-time debugging, and a unified dashboard that lets users deploy fullstack apps in minutes. Developers no longer need to handle node infrastructure, manage chains, or spend hours configuring smart contract environments.

  • Chainhook is Hiro’s event-based automation tool that enables developers to create if-this-then-that (IFTTT) logic based on onchain events. Whether tracking a transaction on Bitcoin or reacting to smart contract calls on Stacks, Chainhook can trigger custom backend processes or alerts with minimal setup.

  • Yes, Hiro provides access to a cloud-hosted Devnet, allowing developers to spin up a private Stacks test network. It’s ideal for securely testing smart contracts, verifying logic, and simulating live transactions before going public. This greatly reduces the risk of bugs or security issues.

  • Hiro’s APIs give developers access to a broad range of Bitcoin and Stacks blockchain data, including address balances, miner activity, Ordinals inscriptions, BRC-20 metadata, and even finalized transaction status through the Stacks Explorer. These APIs are reliable and production-ready.

  • While Hiro is optimized for Bitcoin layers like Stacks and Ordinals, its modular tools such as Clarinet, Chainhooks, and token metadata APIs can benefit any developer looking to build Bitcoin-secured applications. The ecosystem is growing to support hybrid use cases that bridge other chains with Bitcoin’s security model.
