## Authors Frax Core Team # Summary This proposal builds on[FIP-430](https://gov.frax.finance/t/fip-430-preparation-for-frxusd-payment-stablecoin-charter-compliance/3698?utm_source=chatgpt.com), which established a separate balance sheet and governance-guided yield strategy for sfrxUSD, by whitelisting an initial set of AMO strategies with allocation caps and setting clear rules for how future strategies are approved. The aim is to ensure sfrxUSD remains the onchain benchmark yield stablecoin, with allocations that are transparent, risk-managed, and always guided by a minimum yield rule to prevent subsidizing below-market opportunities. # Background and Motivation sfrxUSD was launched as part of Frax’s Payment Stablecoin Charter framework to serve as the onchain benchmark USD yield stablecoin. In FIP-430, the DAO approved the establishment of a separate sfrxUSD balance sheet with governance-guided yield strategies, ensuring its liabilities and assets remain isolated from legacy FRAX and frxUSD reserves. With sfrxUSD now upgraded, the next step is to whitelist initial AMO strategies and provide a framework for how future strategies will be evaluated. This proposal clarifies which venues may receive sfrxUSD allocations, sets maximum caps for each, and establishes rules for approving new strategies. It also introduces a minimum yield rule to ensure allocations are capital-efficient and always benchmarked against the current sfrxUSD APY. The objective is to create a clear, durable framework that both operationalizes sfrxUSD in DeFi and provides governance with consistent criteria for evaluating future opportunities. # Proposal Details ### ## AMO Strategy Whitelist (Initial Package) 1.

Allocating capital below the current epoch sfrxUSD APY creates direct opportunity costs for holders and risks effectively subsidizing external protocols. At the same time, over-allocation can stress the sfrxUSD ↔ frxUSD redemption balance, since a large portion of lent assets may be borrowed and sold. The minimum yield rule and sustained-yield requirement ensures sfrxUSD allocations are both capital-efficient and resistant to APR gaming, while governance caps prevent smaller protocols from lobbying for disproportionate allocations. # Voting - For: Approve the listed sfrxUSD AMO whitelist with allocation caps, and adopt rules for adding new strategies - Against: Do nothing. ---

Hi there - am broadly supportive - when is the FIP up for snapshot voting please? ---

a lot of these strategies is build around farming gov tokens. will we start to acc some of them in the strategic reserve if we have any excess after selling for creating the sfrxusd yield? From what I can see the usde in the proposal is right now on the l-frax balance sheet. will we be moving it to the sfrxusd balance sheet or? ---

> [@Klaasek](#): > > will we start to acc some of them in the strategic reserve if we have any excess after selling for creating the sfrxusd yield? That’s a great question. Since **sfrxUSD is designed as a yield-bearing stablecoin** , the default approach is to sell governance/reward tokens in order to generate stable yield for holders. However, if governance determines that holding certain volatile assets strategically strengthens the overall sfrxUSD strategy, we could add them as part of the reserve allocation. ---

> [@Klaasek](#): > > From what I can see the usde in the proposal is right now on the l-frax balance sheet. will we be moving it to the sfrxusd balance sheet or? the **LFRAX balance sheet currently shows the LFRAX/USDe holding** , and it is not part of the sfrxUSD balance sheet. Once this proposal is accepted, the **sfrxUSD balance sheet will begin allocating into new strategies** accordingly, which include USDe positions. ---

Why not increase the capacity of frxUSD and wfrax in BAMM?
