What if the BTC you have could participate in DeFi without ceasing to be... BTC?
For years, the promise of Bitcoin in decentralized finance has been trapped behind wrapped solutions and custodial bridges. But that is changing.
Caldera has just launched “BTC Connect”, an interoperability layer that allows its rollups to interact directly with the Bitcoin network using verification mechanisms based on native signatures. What’s the difference? No need to wrap BTC or rely on traditional custodians. Custody remains linked to the original Bitcoin wallet, and that changes the game 🧩.
🚀 What does this mean in practice?
Projected initial TVL, with estimated growth for the coming years
Use cases such as lending, yield, and cross-chain payments are enabled with BTC backed by native signatures
The risk of centralized custody is significantly reduced, one of the biggest obstacles for BTCFi
This approach aligns with a broader trend: trust-minimized infrastructure that returns control to the user. It’s not just a technical improvement, it’s a philosophical evolution.
📊 Why does it matter?
According to Our Crypto Talk, the Bitcoin ecosystem is unlocking dormant liquidity. Projects like Fiamma Bridge and BTC Connect are addressing the classic trilemma: security, efficiency, and multichain flexibility.
With BitVM2 and ZK proofs, verification can be done directly on Bitcoin, although with certain technical limitations that are still being optimized.
🌍 Long-term impact
For developers: new possibilities to build on BTC with less friction
For users: access to DeFi without directly compromising custody
For the ecosystem: greater liquidity, participation, and potential institutional adoption
This type of interoperability not only expands the reach of Bitcoin but could redefine its role in Web3. It is no longer just a store of value: it is an evolving programmable asset.
