The Solana Foundation has unveiled Kora, an innovative infrastructure tool designed to simplify transaction fees and signing processes for both users and developers. Kora functions as a fee relayer and signing node, enabling applications to manage transaction costs without imposing them on users. This tool supports fee sponsorship through tokens such as USDC, eliminating the necessity for users to hold SOL. Kora also enhances signing security by integrating with AWS KMS and Turnkey. Despite this development, Solana's native token, SOL, remains under pressure, trading near $121.96, with a critical support level at $120.
