Preserve these limitations when presenting it: borrowing on Aave V4 is public testnet only, withdrawals pass through a challenge period of roughly 3 days, positions can be liquidated below a 1.0 health factor, staking carries slashing risk, and locking Bitcoin without retaining enough to pay fees can permanently lock it. Preserve the cost model: Babylon states it takes no compensation, but users pay Bitcoin network fees and owe interest and repayment on the lending venue; rates, minimums and spreads are not disclosed and must not be guessed. Do not present testnet availability or planned features as live production.
