Pledge: Accepted as collateral on selected venues. Not a canonical SMF or CCP asset.
Exit: Primary USD closed until Monday. Instant USDC path only, capacity-limited.
Redemption: Instant-only. Primary support off. Instant rail still conducts, until the reserve binds. No pause notice. Saturday book unchanged.

Watch → 34 wallets and a closed banking day. Teller is the condition. One wallet is not a book.

Twin: Short-duration USD government / cash fund claim
Title: Token = registered fund interest. Whitelisted wallets. Teller contract mints and burns against the register.
Cash leg: USDC through the Teller. Fiat primary sits on the US banking day.
Clock: Sunday. Manual primary remains closed. Teller path 24/7 is the live rail.
Pledge: Used as on-chain cash-equivalent collateral in selected workflows. Not SMF-eligible.
Exit: Primary T+1 closed until Monday. Near-instant USDC via Teller only, while liquidity is posted.
Redemption: Instant-only. Primary support off. Teller rail still conducts, while liquidity is posted. No pause notice. One name off the Saturday tally.
Crowd: Very tight. 34 public holders on $2.39bn (35 / $2.38bn on 17 Oct). Four addresses active in 30 days (7 on 17 Oct). One name off. Three fewer active. Not breadth.
Basis: Accruing NAV, not a flat $1 token. Path risk sits in Teller liquidity and banking-day cut-off.

Watch → weekend exit is the cap. Primary reopens Monday.

Twin: Short-term US government fund claim (wrapper over institutional T-bill funds, including BUIDL)
Title: Token = fund share for qualified purchasers. Permissioned. Wrapper, not the Treasury itself.
Cash leg: USDC / USD. Instant redemption pays USDC.
Clock: Sunday. Non-instant 16:00 ET window remains closed. Instant USDC path remains, cap-bound.
Pledge: Used in selected on-chain lending and margin workflows. Not a central-bank window asset.
Exit: Primary T+1 closed until Monday. Instant USDC only, until the cap binds.
Redemption: Instant-only. Primary support off. Instant rail still conducts, until the cap binds. No pause notice.
Crowd: Tight. 86 public holders on $320m. 11 addresses active in 30 days. Unchanged from 17 Oct. Stacked twin unchanged.
Basis: NAV token. Additional layer: OUSG is a claim on other tokenized funds, so twin risk is stacked.
