Wu said that after Makerdao, LlamaRisk published a proposal in the AAVE community, suggesting that WBTC LTV be reduced to 0 due to concerns about BitGo's custody transfer of WBTC to prevent additional borrowing with WBTC collateral without affecting the positions of existing users. Previously, there have been proposals to add Coinbase's cbBTC to the Aave v3 protocol on the Mainnet master instance and Base, and to add Threshold Network's tBTC to the Aave v3 protocol on Ethereum, Arbitrum, and Optimism.
