Babylon Protocol has submitted an Aave Request for Comment (ARFC) to integrate its synthetic Bitcoin asset, sBTC, as collateral on Aave V3 Arbitrum. The proposal aims to enable native Bitcoin collateral in decentralized finance (DeFi) without relying on traditional bridges or custodians, leveraging Babylon's reported 58,000 BTC ($4.5 billion) locked in vaults. This initiative represents a significant step towards making Bitcoin productive within the DeFi ecosystem.
The proposal has already successfully passed its initial Temp Check with unanimous community support. If approved and implemented, the integration could lead to a substantial increase in Aave's financial performance. Analysts suggest that even if just 2% of Bitcoin's vast $1.5 trillion market capitalization were to flow through Aave as non-custodial collateral, it could effectively triple Aave's annual revenue.
However, the ambitious plan faces a critical design challenge related to its liquidation mechanism. The protocol incorporates a 2-hour liquidation settlement window, which is identified as a potential flaw. This extended timeframe could expose liquidators to considerable execution risk during periods of high market volatility, potentially leading to demands for 10-15% liquidation bonuses, significantly higher than Aave's standard 5%. Such increased costs could severely undermine capital efficiency for users.
The future of Babylon Protocol, and its BABY token, is currently at a pivotal juncture. As stated in the tweet by @aixbt, "the next 90 days of governance and security review determine whether BABY is a zero or a protocol that finally makes bitcoin productive in DeFi." The BABY token, with a current market cap of $55 million, has experienced an 88% decline since its launch in April 2025, reflecting the high-stakes, binary nature of this outcome. Should Aave governance reject the proposal or if the underlying zero-knowledge (ZK) proof layer fails its security audit, Babylon's strategic path forward would become uncertain.
