Bear market positions shrinking, at this time the most needed is to find a reliable way to earn some interest passively. Recently, while reviewing projects, I discovered an interesting idea—some teams have fully transferred the Korean premium arbitrage structure onto the blockchain to create synthetic USD products. The current real-time APY remains steady at 18.01%, with the price firmly anchored at 1.00 USDT.

**How the Arbitrage Logic Works**

Simply put, it captures market price differences, completely independent of inflation mining strategies. Since 2017, due to capital controls and local demand, Korea has repeatedly experienced premium phenomena. The protocol’s AI monitoring system continuously seizes these opportunities: when premiums are high, it sells USDT in Korea and hedges against KRW exchange rate risk; when low, it replenishes inventory in the opposite direction. The profits are partly added to the protocol’s reserve fund and partly distributed to holders. There’s no issue of token dilution.

**Political Changes by the End of 2025 Actually Turned into an Advantage**

In December, political fluctuations in Korea combined with the weakening of the Korean won pushed the premium to 3-5% (according to CryptoQuant data, the highest in the past four months), fully activating the arbitrage engine. Currently, the APY remains stable around 18%. The protocol’s conservative goal is to maintain 18%, and backtesting data shows that at certain stages it even exceeded 40%. In the long term, maintaining a sustainable return of over 10% is a more realistic expectation.

**How the Mechanism Supports These Returns**

The core is the 1:1 USDT minting mechanism, which provides a solid foundation for price anchoring. Holders participate in profit sharing through staking—each arbitrage completion automatically channels profits in. The entire logical loop is very hardcore, not a project that relies on new capital inflows to sustain itself.
