First Ever Bitcoin–Cardano Bridge Enters Final Development Phase

Leading Cardano-based DeFi ecosystem, FluidTokens, has confirmed that the first-ever BTC-ADA bridge is launching soon.

According to the announcement, the bridge has entered its final development phase. BIFROST is now finalizing its GitHub documentation, with active updates continuously added to the repository. As a result, the project is nearing implementation and public release, transitioning from theory to deployment readiness.

Key Points

• FluidTokens confirmed that the BTC↔ADA Bridge has officially entered its final development phase.
• BIFROST is finalizing GitHub documentation for the bridge.
• The BTC-ADA Bridge would allow cross-chain liquidity flow between Bitcoin and Cardano.
• The initiative aligns with growing efforts to position Cardano as the ideal blockchain for Bitcoin DeFi.

BTC-ADA Bridge Enters Final Development Phase

In a tweet, FluidTokens confirmed that the BTC-ADA Bridge is now in its final development phase. The protocol seeks to enable Bitcoin liquidity to be utilized directly within the Cardano ecosystem.

Historically, Bitcoin has functioned primarily as a store of value, with limited participation in decentralized finance (DeFi). This bridge aims to change that by enabling BTC to interact with Cardano’s smart contract infrastructure, unlocking new financial use cases while preserving Bitcoin’s role as a foundational asset.

The announcement follows the testnet launch of Fluidly by FluidTokens, which enables trustless peer-to-peer swaps between BTC, ADA, and ETH. The protocol lets users link wallets and post on-chain swap offers that settle atomically once conditions match, without intermediaries or liquidity pools.

Fluidly is now live on the Cardano testnet 🚨

Link two of your wallets, where you’d like the trade to happen, and swap by posting an offer with settlement happening atomically on the chain.

What This Means for Cardano and Bitcoin

The bridge’s entry into its final phase suggests that Bitcoin’s capital could soon become fully functional on Cardano. Once it goes live, the bridge will allow cross-chain liquidity flow between Bitcoin and Cardano and enable BTC-backed DeFi applications on Cardano.

It will also provide new mechanisms for users to mobilize long-term, idle BTC holdings without selling, while strengthening Cardano’s position as a hub for secure, multi-chain liquidity.

Once operational, the bridge would allow BTC to be used in lending, liquidity provision, and other DeFi mechanisms on Cardano. This unlocks new economic utility for long-held BTC while preserving its monetary properties.

Cardano Targets Leadership in Bitcoin DeFi

Meanwhile, Cardano is positioning itself as a hub for Bitcoin DeFi. Founder Charles Hoskinson and other stakeholders are actively driving this vision, with Hoskinson projecting that Bitcoin DeFi will eventually surpass Ethereum’s market cap.

Last year, at the Bitcoin conference, Patrick Tobler demonstrated a live swap of Bitcoin for Minswap tokens directly on Cardano, prompting Hoskinson to welcome Bitcoin DeFi to the network.

In June 2025, IOG launched Cardinal, Cardano’s first Bitcoin DeFi protocol, enabling users to bridge, stake, and lend BTC within the EUTXO model without centralized custodians.

Additionally, EMURGO partnered with BitcoinOS to expand Bitcoin DeFi on Cardano. Following the deal, Hoskinson announced plans to revive the Bitcoin Education initiative to train developers to build smart contracts on Cardano using Aiken programming language.
