Charles Hoskinson Says Pogun Could Bring Bitcoin Liquidity to Cardano DeFi
Cardano founder Charles Hoskinson says Pogun could address one of the network’s biggest DeFi challenges by bringing Bitcoin liquidity onto Cardano. His proposal is built around putting Bitcoin to work through lending and stablecoin markets rather than requiring holders to sell their BTC.
Hoskinson’s Bitcoin DeFi Strategy
Hoskinson described Pogun as a way to mirror significant amounts of Bitcoin into Cardano, creating liquidity that could then support lending and stablecoin activity. In his view, that combination could expand both total value locked and stablecoin liquidity across the Cardano ecosystem.
The basic idea targets a long-standing limitation for Bitcoin. While Bitcoin holds a large amount of capital, its native network does not provide the same range of lending and decentralized financial applications available on smart-contract platforms. Pogun is being developed to connect Bitcoin-backed capital with those financial use cases.
Pogun’s own documentation currently describes the project as building Bitcoin-backed credit based on fixed terms. The proposed system is designed around direct agreements between lenders and borrowers, with no pooled lending risk and no price-triggered liquidation mechanism.

The project is also working on its Mirror system, which is intended to use Bitcoin as collateral while keeping the underlying Bitcoin on the Bitcoin network. Pogun says the mechanism uses a BitVM-based design, although its Bitcoin collateral system remains a prototype rather than a live production service.
That distinction matters because Hoskinson’s broader vision is considerably larger than what is currently operational. The potential for substantial Cardano TVL depends on Pogun successfully deploying its infrastructure, attracting Bitcoin liquidity and developing the lending and stablecoin applications needed to turn that liquidity into active DeFi capital.
Cardano already has a stablecoin ecosystem that includes USDCx, USDM, USDA, DJED and iUSD. The Cardano Foundation describes stablecoins as an important component of the network’s DeFi activity, particularly for lending and trading.
If Bitcoin liquidity enters those markets, the potential effect would extend beyond simply increasing TVL. Bitcoin-backed positions could provide collateral for borrowing stablecoins, while those stablecoins could then circulate through lending, liquidity and other DeFi applications.
Pogun’s Bigger Cardano Opportunity
Hoskinson’s argument is therefore based on a sequence: bring Bitcoin liquidity to Cardano, use that liquidity to support credit markets, create stablecoin liquidity and then give those assets somewhere to generate returns within DeFi. He believes that could address two metrics frequently used to assess blockchain ecosystems: TVL and stablecoin supply.
Pogun’s developers are pursuing a structure designed to reduce some of the risks associated with conventional Bitcoin lending. Its published model says Bitcoin collateral is separated by loan, is not pooled or rehypothecated, and cannot be liquidated simply because the market price moves. Default would instead depend on the agreed terms of the loan.
The technical approach also has a Cardano connection. Input Output has described Pogun’s architecture as combining Bitcoin verification, Cardano state attestation and an operator transaction structure to create a trust-minimized Bitcoin DeFi system. The company has also acknowledged that production reliability remains an important question for the architecture.

For Cardano, successful execution could give the network access to capital that does not originate from the ADA market. That is important because attracting Bitcoin liquidity would allow Cardano’s DeFi ecosystem to grow around an asset with a much larger existing capital base, rather than depending exclusively on ADA holders and Cardano-native assets.
There are still major uncertainties. Pogun’s Bitcoin collateral mechanism has not reached production, and bringing Bitcoin into a DeFi environment involves technical, liquidity, security and economic risks. A large theoretical Bitcoin market also does not guarantee that holders will choose Cardano over competing Bitcoin DeFi platforms.
The project therefore represents a potential strategy rather than an established source of Cardano TVL. If Pogun can move from prototypes to a reliable production system and attract meaningful Bitcoin liquidity, Hoskinson’s vision could materially expand Cardano’s DeFi market. For now, the next milestones are deployment, security and actual user adoption rather than projected TVL.
The broader significance is that Cardano is attempting to solve its DeFi liquidity challenge by looking outside its own asset ecosystem. Rather than relying solely on new ADA demand, Pogun is designed to make Bitcoin capital productive through Cardano-based financial infrastructure. Whether that becomes a major source of liquidity will depend on how successfully the technology moves from development into real-world use.
