According to PolynomialFi on Twitter, traders can now use ETH, SolvBTC, wstETH, and weETH directly as collateral on Polynomial, eliminating the need to convert assets to USDC for trading. This update streamlines the trading process, reduces conversion costs, and offers greater flexibility for users, which may increase trading volume and liquidity on the platform. The direct use of these popular crypto assets aligns with growing demand for multi-collateral trading options and could positively impact both DeFi adoption and token utility.
