Stacks swaps

May 15, 2025

Disclaimer: Leather does not operate token swap protocols. Users should review pricing, slippage, gas costs, and smart contract risks before confirming any trades. Always double-check token names, slippage, and network fees before swapping. Some tokens may have limited liquidity or price volatility.

Swapping on Stacks refers to exchanging one token for another using decentralized protocols built on the Stacks blockchain. These swaps are powered by smart contracts that handle trades automatically without relying on centralized exchanges or custodians.

What can you swap?

You can swap between a wide variety of Stacks-based assets, including:

  • STX (Stacks token)

  • sBTC (Bitcoin-backed token)

  • ALEX (DeFi protocol token)

  • USDh (stablecoin)

  • Various other SIP-10 tokens supported in DeFi

Swaps are routed through liquidity pools where users provide token pairs in exchange for fees and yield.

How swaps work

When you initiate a swap:

  • A smart contract checks the current exchange rate and available liquidity

  • You approve the transaction in Leather

  • The tokens are exchanged in a single, on-chain operation

Most swaps are instant, transparent, and non-custodial. Allowing users to keep control of their wallet or private keys.

Swapping with Leather

Leather connects directly to Stacks-based swap protocols like ALEX and Bitflow. Inside the wallet or when connected to a dApp, you can:

  • Select tokens to swap

  • Enter an amount and review the exchange rate

  • Approve the transaction and track the result on-chain

Swapping from your wallet puts you in control while enabling participation in DeFi markets secured by Bitcoin.
