In a recent talk, Charles Hoskinson, CEO of Input Output, highlighted groundbreaking developments in merging Cardano and Bitcoin’s capabilities. He stressed that the long-awaited integration of decentralized finance (DeFi) functions into Bitcoin is now a reality, not merely a theoretical framework. In a conversation with Crypto Megan, Hoskinson outlined the innovative architecture and the substantial potential that this collaboration harbors, describing it as a “multi-trillion dollar opportunity” to enhance Bitcoin’s liquidity with Cardano’s robust programmability features.
“This is not the beginning,” Hoskinson proclaimed, “but rather the midpoint of a comprehensive journey exploring how Bitcoin can reach new levels of programmability.” He explained that what started as early experiments with projects like Colored Coins and Mastercoin has evolved into tangible interoperability driven by significant technological advancements such as Taproot, BitVMX, and a growing network of partnerships.

Innovative Cardano Technology on Bitcoin Mainnet
One of the most notable updates from Hoskinson was the confirmation that live transactions are successfully occurring between the Bitcoin mainnet and Cardano mainnet. He remarked, “We’ve already demonstrated transactions between the two mainnets where an ordinal is capable of moving seamlessly.” This achievement not only validates the underlying concept but also showcases its scalability.
According to Hoskinson, Cardano will operate as a vital computational layer that complements Bitcoin’s established value and security framework. He explained, “Bitcoin provides a secure audit layer while Cardano excels as a computational powerhouse. Merging these elements allows us to create an exceptionally smooth user experience.”
A significant aspect of this streamlined user experience involves a user-friendly toggle feature. Hoskinson pointed out, “With a simple switch, users can engage ‘DeFi mode’ without any distractions about different networks. All transactions require fees payable in Bitcoin, and all returns are delivered in Bitcoin.”
From a design perspective, maintaining a connection to Bitcoin’s cultural ethos is crucial. Hoskinson outlined three essential criteria for any legitimate Bitcoin DeFi framework: it should utilize Bitcoin for security, mandate payment of fees in Bitcoin, and yield returns in Bitcoin. He stated, “Failing to present this core experience will leave you behind in the philosophical, cultural, and technological landscape.” He acknowledged that this had been a long-standing challenge, but now, he is confident that a solution has been realized.
The growing infrastructure, driven by contributions from partners aligned with Cardano, such as Fairgate, Sundial, and the Lace Wallet team, is evolving quickly. This toggle feature was first introduced at a recent Bitcoin conference and is currently operational within the Lace desktop wallet.
Moreover, Hoskinson unveiled that Cardano’s development environment is being effectively employed on Bitcoin through BitVMX. “We actively investigated whether Cardano’s programming language could be adapted to write Bitcoin scripts,” he noted, following this with live demonstrations showcasing tools across both chains.
The compatibility extends to the Babel fees mechanism in Cardano, which accommodates transaction payments in various currencies, including Bitcoin. “Think of it like a tourist visiting France, paying with dollars without realizing they’re spending euros… Under the surface, ADA is in play, but users remain unaware of it,” Hoskinson explained.
In addition, Hoskinson expressed interest in developing a Bitcoin-backed algorithmic stablecoin, leveraging Cardano’s expertise with the Jed stablecoin and his preliminary work with BitShares. “Creating a Bitcoin-backed stablecoin would be phenomenal. It’s akin to the Bretton Woods system—transitioning from gold-backed to Bitcoin-backed money,” he added.
Addressing the adoption process, he underscored that enhancements in user experience, reduced fees, and clear trade-off controls are paramount. “The security model should be a decision made by the user,” he asserted, describing a user interface where Bitcoin enthusiasts can activate a purist option, while those seeking efficiency might prefer lower costs and quicker processing times.
Hoskinson positioned this initiative as part of a larger movement towards practical cross-chain collaborations in the cryptocurrency arena. “Bitcoin and Cardano enhance one another’s strengths,” he remarked. “This marks a transformative phase in the crypto landscape. We’ve established a truce in previous rivalries.”
The potential scale is astonishing. “This integration could vastly exceed the combined market cap of Solana and Ethereum,” Hoskinson claimed. “Given the upcoming bull market, Bitcoin has access to nearly limitless liquidity, making this ecosystem increasingly essential.”
While Cardano has persistently pursued this integration, Hoskinson emphasized that shifting from vision to actual deployment on the mainnet signifies a monumental change. Cardano’s roadmap for Bitcoin DeFi is now firmly rooted in reality—operational, on-chain, and primed for growth.
As of the latest updates, Cardano is trading at approximately $0.7598.
