Michael has been holding 2 $BTC on Binance since 2021. Like many long-term Bitcoin holders, he wanted access to liquidity without selling his BTC. He also didn't want to use wrapped BTC, bridges, or custodial solutions.
A member of TF Premium introduced him to Babylon Trustless Bitcoin Vaults (TBV) and helped him get started. $BABY
Michael created his own Trustless Bitcoin Vault and locked 1 BTC directly on the Bitcoin blockchain using a Taproot script. His BTC never left Bitcoin, was never wrapped, and stayed in a vault owned only by him
@BabylonLabs_io then used a Bitcoin Light Client and Zero-Knowledge Proofs to verify his BTC as collateral on Ethereum. Everything was verified on-chain, removing the need to trust a bridge, custodian, or intermediary.
Once verified, Michael used his vault as collateral on Aave v4 to borrow USDC while keeping full ownership of his native BTC. Throughout the process, his Bitcoin remained secured by the Bitcoin network.
After repaying the loan, he simply redeemed his BTC back to his Bitcoin address.
Babylon TBV gives Bitcoin holders a new way to unlock liquidity without giving up self-custody or decentralization. Instead of wrapping BTC or relying on bridges, native Bitcoin stays on the Bitcoin blockchain while becoming verifiable collateral for DeFi on Ethereum. It turns idle BTC into a productive asset without compromising the security that makes Bitcoin unique.

David, 78 years old, used to keep gold hidden under his bed because, as he always said, “I don't trust anyone.”
One day, his grandson showed him Trustless Bitcoin Vaults (TBV) from @BabylonLabs_io .
“Grandpa, you can keep your native Bitcoin under your own control and still borrow against it.”
“No middlemen?”
“None. It's self-custodial, uses native $BTC as collateral, and is completely trustless.”
David smiled and replied, “Now that's something I'd actually like to try.”
That conversation perfectly reflects a challenge Bitcoin holders have faced for years.
Bitcoin is the largest and most trusted asset in crypto, yet participating in DeFi has usually required wrapping BTC, bridging it across chains, or relying on trusted intermediaries.
TBV changes that by allowing native Bitcoin to be used as collateral without wrapping, bridging, or giving up self-custody. $BABY
One of the first use cases is native Bitcoin-backed borrowing with Aave v4. Instead of selling BTC, users can deposit native Bitcoin as collateral and borrow supported assets such as USDC or USDT on Ethereum, making their Bitcoin more capital efficient while continuing to hold it.
The Public Testnet is now live, giving everyone a chance to experience the complete borrowing flow powered by TBV. If you're curious about how native Bitcoin-backed borrowing works, try the testnet yourself and don't forget to submit your feedback to help improve the product.
I'm excited to see Bitcoin becoming more useful across DeFi while staying true to its core principles.
