People often describe Bitcoin as digital gold, and over time that comparison has shaped how people use it. Gold is something you store. Bitcoin gradually became the same. Once you own it, the safest decision often feels like leaving it untouched.
That way of thinking didn't appear By accident. For years, using BTC in DeFi usually meant wrapping it, bridging it, or accepting additional trust assumptions. Holding became the simpler option, so Bitcoin earned a reputation as an asset that mostly sat on the sidelines while other assets powered on-chain finance.
One question I've found myself coming back to is whether that reputation, is a property of Bitcoin itself or simply a result of the infrastructure we've built around it.
That's where @BabylonLabs_io made me thinking. Trustless Bitcoin Vaults (TBV) take a different starting point. Instead of asking users to transform Bitcoin before it beComes useful, the design explores whether native BTC can remain native while also serving as collateral. The first public testnet, built around native Bitcoin-backed borrowing with Aave v4, is an early example of that idea in practice.
What interests me isn't just the borrowing flow. It's the possibility that Bitcoin doesn't have to choose between being a long-term store of value and participating in on-chain finance. If native collateral becomes practical, those two roles may not be as separate as they've traditionally been.
Whether that changes user behavior is another question. People don't abandon familiar models overnight, and wrapped assets already have years of liquidity and integrations behind them. I'm curious whether Bitcoin's future is simply holding it more securely, or finding ways to use it without changing what made it valuable in the first place.
People often assume that using Bitcoin in DeFi means wrapping it or bridging it to another chain. That assumption isn't surprising because wrapped BTC has been the foundation of most Bitcoin-based DeFi for the years. It made Bitcoin easy to integrate with existing protocols, but it also introduced additional trust assumptions that don't exist when holding native BTC.
One approach that caught my attention is how @BabylonLabs_io is tackling this with the Trustless Bitcoin Vaults (TBV) . Instead of treating wrapped BTC as the default, TBV is designed to let native Bitcoin be used as collateral without wrapping, bridging or relying on centralized intermediaries. Rather than recreating Bitcoin on another network, the dEsign starts from the idea that Bitcoin should remain native while still being useful across the on-chain applications.
The first implementation is native Bitcoin-backed borrowing through Aave v4 on Babylon's public testnet. It shows that Bitcoin liquidity can participate in DeFi without depending on the traditional wrapped asset model.
That's where the architecture becomes interesting. Wrapped BTC became the industry standard because it fit naturally into existing DeFi infrastructure. TBV asks a different question: if native Bitcoin can deliver similar functionality, do we still need to rely on wrappers and bridges as the default?
The more interesting question isn't whether native BTC can be used as collateral. Babylon has already demonstrated that through its public testnet. What matters now is whether this model can expand beyond lending into areas like stablecoins, derivatives, and other financial applications without changing the trust assumptions it aims to preserve.
I'll be exploring the public testnet to see how the borrowing flow works in practice. I'm also curious whether others think native Bitcoin collateral can realistically cOmpete with the liquidity and network effects that wrapped BTC has built over the years.
