The Solana ecosystem welcomes a new member - the Kora project is officially launched. This is a fee relay and signature node solution specifically designed for the Solana network, aimed at optimizing the user transaction experience. The core innovation of Kora lies in achieving zero-fee transactions, customizable fee tokens and other features, which means users can complete on-chain operations under more flexible payment methods. The launch of this project helps to drop the cost threshold for participants in the Solana ecosystem, further improving the infrastructure construction of the ecosystem.
