Bitcoin–Cardano Bridge Nears Launch: Is DeFi About to Transform?

TLDR

• BIFROST confirmed that the Bitcoin–Cardano bridge has entered its final phase of development.
• The bridge will allow Bitcoin to be used in Cardano’s decentralized finance ecosystem.
• FluidTokens is actively finalizing the GitHub documentation for the bridge.
• The BTC–ADA bridge will enable cross-chain liquidity flow between Bitcoin and Cardano.
• The protocol uses smart contracts to allow trustless swaps without intermediaries.

BIFROST has confirmed that the Bitcoin–Cardano bridge has now entered its final development stage, nearing full deployment, and GitHub documentation is actively being finalized as the project transitions toward public release.

This development marks a technical advancement in enabling Bitcoin to operate within Cardano’s smart contract framework, and the bridge is designed to support direct cross-chain liquidity between the two networks. With active updates being pushed to the repository, implementation efforts are accelerating as developers prepare for launch.

BTC–ADA Bridge Enters Final Phase

FluidTokens officially confirmed in a tweet that the BTC–ADA bridge has entered its final phase of development. The bridge aims to allow Bitcoin to move freely into Cardano’s decentralized finance infrastructure. It is designed to support atomic swaps and direct liquidity movement across both chains.

BIFROST is finalizing the bridge’s documentation on GitHub while maintaining active code updates. This effort signals that the technical build is near completion. Development teams are now aligning for deployment readiness.

The bridge will allow cross-chain functionality without custodians, relying instead on smart contracts. It will enable BTC to be used within ADA-based DeFi applications. This integration increases Cardano’s utility while retaining Bitcoin’s monetary characteristics.

Bitcoin–Cardano Bridge to Unlock Cross-Chain Liquidity

The Bitcoin–Cardano bridge will allow Bitcoin capital to interact with Cardano’s smart contracts. This aims to unlock new financial use cases for BTC. Users will be able to engage in lending, liquidity provision, and more on Cardano.

The bridge will let long-term BTC holders access DeFi without selling. This creates economic utility for idle Bitcoin assets. At the same time, Cardano gains liquidity flow from a major blockchain.

FluidTokens is also developing Fluidly, which recently launched on testnet. The protocol enables trustless swaps between BTC, ADA, and ETH. Users can link wallets and settle offers automatically once matched.

This protocol uses atomic settlement and does not require intermediaries or pooled liquidity. Users maintain custody while interacting across chains. Such systems aim to improve transparency and reduce counterparty risk.

Cardano Strengthens Push for Bitcoin DeFi

Cardano is now positioning itself as a primary destination for Bitcoin DeFi. Founder Charles Hoskinson has shared his long-term vision for this integration. He recently projected that Bitcoin DeFi could surpass Ethereum in market cap.

In June 2025, IOG launched Cardinal, Cardano’s first Bitcoin DeFi protocol. It supports BTC staking and lending under Cardano’s EUTXO model. The protocol avoids centralized custodians.

Last year, Patrick Tobler demonstrated a BTC–Minswap token swap live on Cardano. Hoskinson welcomed Bitcoin DeFi to the Cardano ecosystem during the event. That marked an early demonstration of real-time BTC use on Cardano.

EMURGO later partnered with BitcoinOS to grow Bitcoin DeFi on Cardano. Hoskinson also announced efforts to train developers using Aiken. The education initiative will support smart contract development for BTC DeFi.
