Aave governance has advanced a LlamaRisk proposal to raise the maximum loan-to-value ratio for WBTC and cbBTC on Ethereum Core from 73% to 81% and lift the liquidation threshold from 78% to 85%. According to NS3.AI, the proposed changes would narrow the simplified collateral-price cushion at maximum leverage from about 6.4% to 4.7%. The Snapshot vote and any implementation were unverified at the reporting cutoff, so the proposed limits were not live settings.
