I used to see BTC become collateral for Aave and would automatically understand it as BTC having been moved into Aave. Only when I actually read through the adapter layer did I realize that what Aave receives is not that specific BTC, but its collateral status.
After the Trustless Bitcoin Vaults (TBV) are activated, the native BTC remains locked in Bitcoin’s Taproot Vault. The Aave v4 Adapter creates an internal collateral record based on the amount of BTC in the Vault, so the lending market can calculate the collateral value and health factor. This record corresponds one-to-one with the locked BTC, but it can’t be transferred to any address and won’t appear in the user’s wallet or secondary markets.
In other words, between the two chains, what’s recognized is the state of things—not an asset that has been copied over. Bitcoin is responsible for storing the BTC, while Ethereum is responsible for reading whether “this BTC is currently in a valid collateral state.” When the Vault is withdrawn or liquidated, the corresponding collateral record is also closed.
I think this is exactly what Babylon is most worth repeatedly understanding. The location of BTC doesn’t change; what changes is whether it can obtain a verifiable use without leaving Bitcoin. In the future, what truly needs to be observed is whether a product allows users to clearly tell at a glance where my BTC is and what Aave is using.
