What is the scariest speed you have ever seen? It's not a price surge; it's a withdrawal. The incident with Cetus on Sui shocked everyone awake: funds were siphoned away as if by a vacuum, and the chain instantly entered 'self-protection mode'—congestion, slippage, price distortion, and panic spread. You think you are trading, but in reality, you are racing against time, and most people lose because 'the exit isn't fast enough'.
This type of hotspot amplifies an overlooked fact: in extreme situations, volatile assets can simultaneously lose two things—price and depth. What you need is not a smarter judgment, but a steadier 'mooring'. This is when USDD should step into the spotlight: when the market turns to shattered glass, USDD, a decentralized and over-collateralized stablecoin, resembles a piece of solid ground where you can temporarily stand.
The significance of USDD is not in 'it never deviates', but in 'when it deviates, it has mechanisms to restore order'. Over-collateralization provides a buffer, PSM provides a correction channel, and multi-chain availability ensures cash can be transferred — these three things combined bring you closer to the 'on-chain dollar' you want. Especially PSM: it gives logic, path, and momentum for repairs when the price deviates, rather than relying on prayer.
Many people will ask: then why don't I just use centralized stablecoins? Because at the moment when 'accidents happen in minutes', you fear two things the most: the channel suddenly slows down, and the rules suddenly change. The narrative of USDD leans more towards being an 'on-chain native dollar tool' — its composability is more suitable for collateral and settlement in DeFi, and its structure is better suited to serve as a 'reset button'. You can exchange your assets back to USDD when an accident occurs, and then decide once the dust settles: whether to return to risk assets or to engage in more stable capital management.
If you want to make the dollar less idle, sUSDD provides another approach: stake USDD into sUSDD, with value accumulation usually reflected through changes in exchange ratios (based on the current page, not constituting a commitment). It is more like 'cash certificate enhancement' rather than 'relying on popularity to subsidize'.
Cetus's kind of accident is not meant to make you exit the market, but to teach you: on-chain, what is truly scarce is not opportunity, but 'the form of dollars that can survive an accident'. USDD is supposed to play this role.
