According to Odaily Planet Daily, OKX has completed a major upgrade to its Smart Arbitrage feature. Users can now stack staking rewards for $SOL and $ETH while activating the Smart Arbitrage strategy. Additionally, OKX has launched limited-time interest rate coupons for $SOL and $ETH, allowing users to combine arbitrage profits, staking rewards, and interest rate coupons for triple overlapping annualized returns, further enhancing capital efficiency and annualized yield. The Smart Arbitrage strategy is designed to achieve stable returns by hedging market price fluctuations. Its core principle is to use a Delta-neutral strategy by holding equal-sized but opposite positions in the spot and futures markets, thereby hedging the risk of price changes.
