Bitcoin Swap

Overview ​

We provide a trustless, user-friendly atomic swap layer that bridges native Bitcoin with the Cardano ecosystem.

This gives you a fast, non-custodial path to swap native Bitcoin into Cardano-based Bitcoin tokens without the complexity of traditional bridges.

Seamless User Experience ​

We have redesigned the atomic swap process to be as simple as a standard transaction, removing the technical hurdles typically associated with cross-chain trading.

  • One-Click Simplicity: You only need to approve one wallet popup to lock your funds. The rest of the process is fully automated.
  • No Manual Secrets: Traditional atomic swaps require users to generate and remember cryptographic secrets. We handle all secret management securely in the background, so you never have to worry about losing a code.
  • Bridge Agnostic: We support multiple Bitcoin representations on Cardano (such as Indigo’s iBTC and others), giving you the freedom to choose the asset that best fits your DeFi needs.

How It Works ​

  1. Select & Quote: Choose your direction (e.g., BTC → Wrapped BTC on Cardano) and get an instant quote.
  2. Lock Funds: Approve a single transaction in your browser wallet.
  3. Sit Back: Once the counterparty deposits their funds, your browser automatically detects it and claims the assets for you.

Safety Features ​

  • Non-Custodial: You maintain control of your assets. We do not hold your funds.
  • Automatic Refunds: If the counterparty fails to lock their funds, you get your money back.
  • Fail-Safe Design: Our system generates secure, temporary "intermediate wallets" in your browser to handle technical signing steps for you. Even if your browser crashes or you lose connectivity, our pre-signed refund mechanisms ensure your funds remain safe.
