Cardano is aiming at a $1.5 trillion Bitcoin-linked market as competition in BTCFi gains speed. After reviewing the launch of Starknet’s strkBTC bridge, Charles Hoskinson said no blockchain has established clear control over Bitcoin DeFi so far, leaving room for Cardano to expand its position in the sector.
Cardano sees an opening in Bitcoin DeFi
The report frames BTCFi as one of the largest underused liquidity pools in crypto. Bitcoin’s market value is massive, yet only a limited portion of that capital is active across DeFi protocols. In Hoskinson’s view, Cardano has a chance to move early and capture part of that gap before rivals such as Stacks, Rootstock, Bitlayer, and Citrea take stronger positions.
His argument rests on Cardano’s existing technical base: a research-led UTXO architecture, ongoing scalability work, and the privacy infrastructure being built around its sidechain Midnight. The UTXO model, or Unspent Transaction Output model, is presented as a structure that can simplify verification while maintaining security and transparency.
Bridge security and privacy demand are shaping BTCFi
BTCFi is designed to let Bitcoin holders use their assets in decentralized financial applications without depending on centralized custodians. To make that possible, developers across the sector are deploying tools such as zero-knowledge proofs, BitVM, shielded transactions, and bridge systems built to minimize trust assumptions.
Bridges remain one of the most exposed parts of DeFi. DefiLlama data cited in the material shows that total value locked across crypto bridge protocols has climbed to nearly $40 billion. The comparison in the article lists Stacks with about $2 billion in locked assets, where attacks and liquidity loss are highlighted as the main risks. Rootstock is shown with roughly $1.5 billion, with single-point failure identified as the primary concern. Cardano is described as a new entrant, facing challenges tied to scalability and integration. Because bridges aggregate liquidity between networks, they continue to attract attackers, pushing infrastructure design toward fewer centralized dependencies and fewer single points of failure.
The report also points to a separate trend: stronger institutional demand for transaction privacy since 2023. That demand has drawn more attention to privacy-oriented blockchain infrastructure and related financial services.
Mainnet atomic swap marks a key Bitcoin integration step
Cardano’s longer-term Bitcoin integration plan has already produced a notable milestone. In March 2026, FluidTokens completed what the report describes as the first native Bitcoin-Cardano atomic swap on mainnet. That matters because atomic swaps allow direct BTC and ADA trading without wrapped assets and without centralized control.
Hoskinson said the plan goes beyond adding Bitcoin liquidity to Cardano alone. He also pointed to Midnight, Cardano’s privacy-focused partner chain, where private debt markets and cross-chain financial services are being treated as development priorities.
According to Cardano’s roadmap, work scheduled for 2026 is expected to shape both its DeFi stack and its position in BTCFi. The developer team is still working on upgrades including Leios and improvements to node performance. Even with those milestones, Cardano remains in active competition with other Bitcoin-focused networks building decentralized applications and liquidity infrastructure.
