Vault and PSM aren’t competing options, they’re tools for different needs.
Vaults make sense if you’re comfortable with collateral ratios and want to mint against assets, while PSM is clearly built for speed and simplicity with clean 1:1 swaps when liquidity is there.
Same stablecoin, different paths depending on how you want to manage risk and capital.
This kind of clarity is what makes USDD easier to use in real DeFi, not just hold and forget.
