1. Your balance and transfers stay private
2. It cannot be frozen
Mainstream stablecoins such as USDT and USDC are controlled by the companies that issue them, and those companies can freeze funds in a wallet. U9 has no freeze button. No company, administrator, or third party can lock the U9 in your wallet.
3. Backed by Bitcoin, protected automatically
Every U9 is backed by Bitcoin reserves worth more than its value. This extra buffer absorbs market swings and helps keep U9 at one dollar.
In an extreme case, if the price of Bitcoin falls below a safety threshold, the system automatically distributes the Bitcoin reserves to all U9 holders in proportion to their holdings, with no approval needed from anyone. Fully homomorphic encryption and secret sharing make this possible while keeping every holder's balance private.
