According to PolynomialFi, traders can now use EtherFi's $weETH as margin on Polynomial, unlocking professional trading strategies and earning opportunities. Participants will benefit from earning 4x EtherFi Points and have a chance to compete for a 100,000 $OP rewards pool. This integration is expected to increase $weETH's trading volume and utility, while also driving user engagement with both platforms. The move highlights growing DeFi composability and could impact Ethereum-based token liquidity and related derivatives markets. Source: PolynomialFi Twitter, May 14, 2025.
