According to PolynomialFi, users can now deposit ETH directly on Polynomial and trade without converting to stablecoins, enabling more seamless and crypto-native trading strategies (source: PolynomialFi Twitter, May 15, 2025). Traders can also earn a share of a 100,000 OP token reward pool simply by making deposits, potentially increasing yield opportunities for active ETH holders. This update removes friction in ETH trading, which may increase liquidity and trading volume on Polynomial, and could influence ETH price action and Optimism ecosystem activity across the broader DeFi and crypto markets.
