Bitcoin collateral can expand Aave's lending business while producing surprisingly little immediate $AAVE buying. Babylon Labs' October 14 proposal sends the first $500,000 of annual qualifying revenue entirely to Aave DAO. Only higher revenue bands fund token purchases. This is a proposed integration, not verified live revenue. [1]
The denominator changes the investment story
Qualifying revenue is not collateral value, borrowed principal or all borrower interest. The proposal includes the Hub liquidity fee on Babylon Spoke borrowing and specified liquidation fees. Aave's V4 architecture separates liquidity accounting from borrowing environments; the protocol's liquidity fee is its retained share of interest. Suppliers also need to be paid. [1,2]
Above the initial $500,000, the proposed purchase allocation is marginal: 4% of the $500,000-$2 million band, then 5%, 6% and 7% in successively higher bands. Of that allocation, 85% buys AAVE and 15% buys BABY. Purchased tokens are divided equally between Aave DAO and Babylon Foundation. These are treasury acquisitions, not a promised burn or cash distribution to holders. [1]
Worked example, not a forecast: $1 million of annual qualifying revenue would allocate $500,000 x 4% = $20,000 to purchases, including $17,000 for AAVE. That is 1.7% of qualifying revenue, before considering total borrower interest as the larger denominator. This calculation concerns this integration alone; it does not measure Aave's separate general buyback program.
My inference: headline collateral growth would be a weak shortcut for token demand. The useful reconciliation runs from interest collected to qualifying fees, expenses and losses, then completed purchases and subsequent treasury distributions. Protocol fees alone do not establish net profit.
Native Bitcoin still needs a liquidation balance sheet
The design keeps BTC on Bitcoin while recognizing collateral on Ethereum. Its two proposed Spokes separate borrowing from liquidation settlement. Permissionless liquidators can receive WBTC at launch; the Swap Spoke borrows that liquidity while authorized arbitrageurs complete the slower native-BTC redemption. The challenge process takes multiple days. [1]
That can make liquidation executable before Bitcoin redemption finishes. It also makes wrapped-BTC liquidity, settlement duration and arbitrageur participation economically important. A cheaper custody model does not automatically produce cheaper borrowing once interest, extra fees, discounts and operational costs are included. That is an analytical tradeoff, not a measured cost advantage.
The October 16 engineering reply adds an important qualification: emergency pause/unpause can be immediate, whereas upgrades and configuration changes have a five-day timelock. A pause blocks repayments and liquidations. Final multisig membership and contract addresses are deferred to the AIP. The original post's broad timelock wording should therefore not be read as a delay on emergency pauses. [1]
Supply discipline and the competing offer
Aave's original token framework specified 16 million AAVE: 13 million for LEND migration and 3 million for the Ecosystem Reserve. Those are historical allocation figures, not today's circulating balance. Current circulating supply, the next reserve release and its percentage of float were not independently verified here. No dated unlock amount is assumed. [3]
AAVE governs protocol decisions. The reserve and treasury finance safety incentives; Aave's token documentation also describes acquired AAVE being reused for rewards, grants and service providers rather than burned. Thus a fixed supply framework does not eliminate increases in tradable float from treasury spending. A reward paid from existing reserves is redistribution, not newly minted supply; neither release nor reward proves an immediate sale. [4,5]
Morpho competes for lending users with isolated, immutable collateral/loan markets and permissionless market creation. Its Vault V2 curators can set performance and management fees and their recipients. Aave's proposed native collateral route must compete on total borrower cost, available liquidity and liquidation reliability, while Morpho's tokenized collateral model has different custody assumptions. Neither architecture alone proves superior adoption or net returns. Comparable live borrowing costs and retained balances were not measured in this review. [6,7]
Evidence to resolve next
The bull case is access to borrowers who prefer keeping BTC on its native chain, plus incremental interest demand during settlement. The countercase is weak demand after incentives, a thin purchase allocation at modest revenue, and losses or liquidity costs overwhelming fees. Risk parameters, final governance approval, deployed addresses, stress-tested liquidation capacity and executed purchases would materially change that assessment. [1]

My take: The proposal deserves attention for improving collateral access. For AAVE, I would value completed purchases against treasury outflows and risk costs, rather than price the entire Bitcoin collateral opportunity as tokenholder income. The $500,000 hurdle makes that distinction concrete.
