been thinking about what your keys, your bitcoin actually means once that bitcoin is sitting as collateral, not just sitting in your wallet
self custodial usually means one clear thing, nobody else can move your funds without you. that's still true here, no company holds your private keys the way a wrapped bitcoin custodian always has. but the moment native BTC gets posted as collateral through Trustless Bitcoin Vaults (TBV), it's not sitting idle in your wallet anymore, it's locked into the vault mechanism that lets Aave v4 actually rely on it for the loan
that's not a flaw, it's just how any collateralized loan works, a car loan ties up the title the same way, you own the car but can't sell it out from under the lender until the loan closes. the honest way to describe self custody here isn't no restrictions at all, it's no third party holding your keys, a real difference from wrapped bitcoin
that clarity matters because the other three benefits only make sense once self custody is understood precisely. capital efficient means the borrow rate is finally priced like defi instead of a bitcoin specific penalty, and that only holds because there's no custodian risk being priced in anymore. native BTC as collateral means the actual asset, not a synthetic stand in, backs the loan. trustless means no centralized intermediary sits between you and that bitcoin the whole time it's posted, even while it's locked into the vault working on your behalf
public testnet is exactly where this is worth testing directly, post native BTC at btc-vaults.testnet.babylonlabs.io, borrow against it, and see how these four pieces behave together
babylon already has real evidence they can secure bitcoin at scale, their staking protocol hit 7.2 billion in TVL at its peak, so this isn't an unproven team guessing at the mechanics for the first time.
