## The memo

REJECTED — published deliberately. USDe is a synthetic dollar whose backing has expanded beyond the original long-spot/short-perpetual trade into stablecoins, lending positions, tokenized funds, and other Risk Committee-approved assets. The core distinction remains: its dollar value depends on an actively managed reserve, centralized derivatives venues, off-exchange custodians, privileged mint/redeem roles, and market makers that alone receive direct redemption access after KYC. sUSDe yield is protocol revenue passed through, sourced from variable funding and basis, staking, and returns on reserve assets; it is not a deposit rate and can fall or turn economically negative before the reserve fund absorbs the difference. The system has handled real stress—$1.9B of redemptions over 2025-10-10 and 11 without using its reserve fund—but USDe also printed as low as 0.65 USDT on Binance during that event because venue-specific liquidity and oracle design failed. Calling this cash invites the wrong sizing. It remains a sophisticated basis-and-reserve strategy wrapped in a transferable dollar token, not a fit for a client whose mandate prioritizes sovereignty and simple, independently enforceable exits.

## What would reopen the file

- Reopen only after twelve consecutive monthly reports reconcile circulating USDe, each custodian balance, hedge notional by venue, unhedged delta, lending and tokenized-fund exposure, and reserve-fund assets at the same timestamp with no unexplained shortfall
- Reopen only if no single custodian or derivatives venue represents more than 25% of backing or hedge notional and every exposure has an independently tested replacement and unwind path
- Reopen only after every live owner, admin, minter, redeemer, gatekeeper, reserve-fund signer and Risk Committee vote is mapped to its address, threshold and enforceable delay, with no undocumented privileged role
- Reopen only if this client has an independently enforceable direct redemption right or a proposed-size secondary exit completes within one business day and 50 basis points during three separate stressed tests; sUSDe must also exit its cooldown within the published tier maximum
- Any reserve shortfall, hedge delta above 2% of supply for more than one hour, direct-redemption suspension beyond one business day, or secondary USDe discount above 100 basis points for more than one hour keeps the product rejected
