Extended FAQ
Borrowing interest rates are determined by Aave v4. Aave adjusts rates based on asset utilization within the Aave v4 Hub, so borrowing costs rise as utilization increases. The rate displayed is annual (APR), while interest accrues continuously. Supported borrowing assets include USDC, USDT, and WBTC and the current borrow rates can be found on Aavescan.
Costs can apply when you create a BTCVault, redeem it through a third-party Vault Provider, or use an integrated application. The amount also depends on the protocol, the Vault Provider you choose, and the integrated application. All of these fees combined, the final fees will be between 0.1%-0.7%. At launch it's planned to be 0% to encourage the usage.
Your borrowing capacity is set by the integrated lending market. On Aave v4, it is typically 70–80% of your collateral value, depending on Aave’s market parameters.
When you deposit, your native Bitcoin is locked into your own self-custodial BTCVault, a UTXO script on the Bitcoin network that holds only your Bitcoin, with no pooling or commingling.
Yes. TBV replaces intermediary control with predefined cryptographic rules. No single intermediary can unilaterally move, seize, or redeem your Bitcoin, which makes it trustless.
To be clear about what trustlessness does not cover: you are not exposed to counterparty risk, but you remain exposed to smart contract and protocol implementation risk, price oracle risk, and the risk profile of the integrated lending application you choose to use.
