Cardano-based UTXO platform FluidTokens completed the first atomic swap between Bitcoin and Cardano on the mainnet.
The transaction in which a small amount of money was exchanged $BTC for $ADAshows that assets on both networks can now be traded directly without wrapping, bridging or relying on centralized platforms.
Key points
- FluidTokens performed the first atomic swap between Bitcoin and Cardano on the mainnet, exchanging 0.0001 $BTC for 50 $ADA.
- The transaction used a structured process that allowed participants to seamlessly fund and complete swaps with both $BTC And $ADA.
- This breakthrough builds on previous efforts by the Cardano ecosystem to integrate Bitcoin, including a demo swap involving native $BTC and the Minswap token.
- Expanding Bitcoin DeFi capabilities remains a key strategic focus for Cardano throughout the year.
First Bitcoin-Cardano Atomic Swap performed
FluidTokens confirmed that it was running the swap directly on the mainnet and exchanging natively $BTC for native $ADA without relying on integrated assets, bridges or centralized intermediaries.
The transaction included a test transaction of 0.0001 $BTC for 50 $ADAdemonstrating that assets on both networks can now move reliably between participants. Blockchain records show that the exchange took place on March 25 for a fee of 2,000 sats, approximately $1.43.
The team used atomic swap technology to complete the transaction. For context, atomic swaps enable transactions between different blockchains without intermediaries, using cryptographic guarantees to ensure fairness between participants.
As a result, either party successfully receives their assets or the transaction fails. In this case, the process enabled a fully decentralized exchange of native Bitcoin for native $ADA.
The exchange followed a structured sequence. First, the owner funded the Cardano side of the transaction, while the buyer deposited Bitcoin. The system then allowed the owner to claim the claim $BTCwhile the buyer was claiming the $ADAeffectively completing the trade without intermediaries.
Remarkable milestone for Cardano
This development significantly advances Cardano’s decentralized finance ambitions, particularly its goal of integrating Bitcoin liquidity into its ecosystem. The network has consistently signaled plans to connect Bitcoin to Cardano, aiming to unlock new DeFi opportunities $BTC holders.
In particular, Charles Hoskinson, co-founder of Cardano, has emphasized that enabling Bitcoin DeFi could drive billions of dollars from the Bitcoin ecosystem to Cardano.
In support of this vision, major ecosystem entities such as Input Output Global, Cardano Foundation, and Intersect have identified Bitcoin DeFi as a core focus area for 2026.
Progress has been made towards Cardano’s Bitcoin DeFi ambitions. During a live demo at a previous Bitcoin conference, a $BTC-to-Miniswap (MIN) exchange via the Lace Wallet.
At the time, the transaction used FluidTokens’ Babel fee system, allowing users to pay fees in Bitcoin. The demonstration prompted Hoskinson to highlight the rise of Bitcoin DeFi, powered by Cardano.
In addition to swaps, Input Output Global has introduced the Cardinal Protocol, which allows Bitcoin holders to access Cardano DeFi while maintaining custody of their assets. At the same time, the collaborations between EMURGO and BitcoinOS aim to provide Bitcoin developers with smart contract capabilities, further strengthening interoperability efforts.
With this latest milestone, FluidTokens has demonstrated that direct Bitcoin-Cardano swaps are now possible on the mainnet. As a result, the project confidently declares that Bitcoin is now effectively on Cardano, signaling a new phase in cross-chain DeFi innovation.
