Which stablecoin briefly depegged on Solana?

TLDR

Solstice USX briefly depegged on Solana, trading well below its dollar peg before recovering after liquidity support was added, per a market report on the event (coverage).

1. At the worst print it hit about $0.10 on some DEX trades due to a liquidity drain (security alert).
2. The issuer said reserves remained overcollateralized and 1:1 redemptions stayed live (issuer statements summarized).
3. Prices rebounded near the peg after Solstice injected liquidity into secondary markets (follow-up report).

Deep Dive

1. What Depegged

USX, a Solana-native stablecoin from Solstice, briefly lost its peg on Solana DEXs. Reports and aggregated DEX data show isolated trades as low as $0.10, with most volume around $0.80 before rebounding toward $0.99 as liquidity returned (market recap).

This was a secondary-market event concentrated on venues like Orca and Raydium rather than a protocol-level failure. The intensity of the wick versus volume-weighted pricing underscores how thin depth can exaggerate prints on DEX order flow (market recap above).

2. Why It Happened

The proximate cause was a liquidity drain that left shallow pools vulnerable to sell pressure, triggering a temporary depeg in secondary markets (security alert). Solstice said the underlying reserves remained overcollateralized and that primary-market 1:1 redemptions were unaffected, framing this as a market-structure issue rather than a collateral shortfall (issuer statements summarized).

Thin holiday-period liquidity can amplify this kind of move. With fewer market makers active and smaller buffers, routine sells can move price far from NAV until arbitrage or issuer support normalizes the gap (issuer statements summarized above).

3. How It Was Resolved

Solstice and market makers injected liquidity into secondary markets, after which USX traded back toward its dollar peg. Coverage noted prices recovered near $0.99 as depth improved and trading normalized (follow-up report).

The issuer also indicated plans for third-party reserve attestations to rebuild confidence and mitigate repeat episodes by deepening secondary-market liquidity over time (market recap).

Conclusion

The stablecoin that briefly depegged on Solana was USX from Solstice. The dip stemmed from thin DEX liquidity rather than reserve failure, and prices recovered after liquidity support. The main takeaway is to differentiate between secondary-market liquidity shocks and underlying collateral risks, and to monitor redemption health and pool depth when assessing stablecoin stability.
