The Snapshot governance page shows that the Aave community has launched the ARFC proposal to "deprecate small-cap stablecoins on the Aave V2 Ethereum network", proposing to eliminate USDP, GUSD, LUSD, FRAX and sUSD on Aave V2. Voting is now open and ends on May 6.
The proposal points out that recent events have highlighted the need for Aave to reduce its V2 exposure to less-used stablecoins, many of which have limited liquidity, allowing price manipulation and other potentially harmful events. Previously, the community followed a two-stage process to deprecate stablecoins, taking BUSD and TUSD as examples. It is worth noting that none of the above stablecoins are collateral assets, which reduces the complexity of the process.
