The brokerage firm Securitize of the Digital Liquidity Fund (BUIDL) has submitted a proposal for improvement to Frax, adding BUIDL as collateral supporting the Frax USD stablecoin. According to the improvement proposal, using BUIDL as a collateral reserve asset can provide yield opportunities, deeper liquidity, and transfer options, and due to the backing of the world's largest asset management company BlackRock, it can reduce counterparty risk.
