Open USD Supply Reaches $666M as Liquidity Concentration Raises Concerns
Open USD (OUSD) has grown to $666 million in total supply, with $100 million deployed on Ethereum in its first week. However, concentration risk is acute: ten wallets hold the majority of tokens, including $396 million in eight Tempo custody accounts that have shown no movement as of early October.

Supply Growth and Concentration
Open USD has reached $666 million in total supply across its deployment, with Ethereum accounting for $100 million of that volume in just its first week of operation. However, liquidity is heavily concentrated: ten wallets control most of the circulating tokens, according to Crystal's October 5 snapshot. Eight Tempo custody wallets alone held $396 million and showed no on-chain movement at the time of the snapshot.
Custody and Institutional Positioning
The rapid deployment of $100 million on Ethereum within one week signals institutional participation in the stablecoin market. However, the movement of such large amounts into custody accounts—Tempo wallets in this case—raises questions about the true liquidity available for trading and redemption. Activity inside these custody accounts remains opaque; whether the tokens are locked in multi-sig arrangements, earmarked for institutional clients, or held pending deployment is unclear from public on-chain data alone.
Risks From Concentration
The concentration of OUSD tokens in a small number of wallets creates both liquidity and stability concerns. If even a fraction of the Tempo-held supply were to be moved or redeemed, it could exert outsized pressure on available market depth. For a stablecoin still in its early weeks, this dependency on a few large holders and custody providers limits the market's resilience to withdrawal demand or loss of confidence.
Why It Matters
For Traders
OUSD's heavy concentration in custodial accounts means liquidity for spot trading or redemption may be thinner than headline supply figures suggest; slippage on larger orders could be material.
For Investors
Concentration risk is a structural vulnerability for a stablecoin competing in a crowded market; institutional lockup does not guarantee organic demand or utility.
For Builders
Projects integrating OUSD should account for the possibility that significant supply is not actively circulating; depth checks and alternative liquidity sources may be necessary.
