Stacks apps

Stacks apps are decentralized applications built using the Clarity smart contract language on the Stacks blockchain. These apps enable functionality like lending, NFTs, DAOs, and marketplaces—all secured by Bitcoin through the Proof of Transfer (PoX) mechanism. With Leather, users can safely connect to and interact with Stacks apps, unlocking Bitcoin-native experiences like Stacking, trading, and DeFi.

Stacks apps are decentralized applications (dApps) built on the Stacks blockchain. They run smart contracts written in Clarity, a language designed for predictability and safety, and use Bitcoin as the settlement and security layer.

Thanks to Stacks’ Proof of Transfer (PoX) mechanism, every app action settles on Bitcoin, giving it permanence and decentralization without modifying Bitcoin itself.

What can Stacks apps do?

Apps built on Stacks include:

  • DeFi protocols like DEXs or swaps (e.g. ALEX, Bitflow, Velar)
  • NFT platforms like Gamma
  • DAOs and governance tools
  • Yield and Stacking participation tools (e.g. Stacking DAO, LISA)
  • Bitcoin-native finance apps like Granite and Zest

Using Stacks apps with Leather

Leather allows you to:

  • Connect to any app built on Stacks
  • Sign transactions and messages
  • See app connection history
  • Manage which apps can read your wallet address These apps may use STX or SIP-10 tokens, and many are already integrated with Leather for a seamless user experience.

Disclaimer

Leather does not operate Stacks apps. Each app is built and maintained by a separate team—users should always review terms and permissions before interacting. Each app on Stacks is independent. Always verify what you’re interacting with and never approve transactions you don’t understand.
