Binance's latest Launchpool for $OPN has introduced a new stablecoin structure, marking the first time U and USD1 are used for mining participation, replacing FDUSD. The reward distribution for this round is set at 80% BNB, 10% USDC, 5% U, and 5% USD1. Previously, the distribution was 85% BNB, 10% USDC, and 5% FDUSD. This change prompts participants to reassess their yield calculations.
