The Foundation launched the ConnectorKit wallet connection SDK and Kora fee relayer, supporting features such as fully paid transaction fees and custom fee tokens, significantly lowering user barriers. Circle’s ongoing large-scale USDC burn and re-mint operations on the Solana network reflect ongoing optimization and adjustments in the stablecoin ecosystem. Although USX briefly de-pegged due to insufficient liquidity, it quickly recovered to around $0.94, and effective stabilization was achieved through liquidity injection, demonstrating the ecosystem participants’ ongoing commitment to improving stablecoin infrastructure.

Kora features include: full support for transaction fees, support for any Token to pay fees (including stablecoins), and transferring signature operations to a secure environment.

BlockBeats news, on December 23, the Solana Foundation announced the launch of Kora, a fee relay and signing node for the Solana ecosystem, supporting fee-free transactions, customizable fee Tokens, and other features. Previously, there was no modern and standardized way to achieve fee payment and remote signing. Although Solana's account model makes these features technically feasible, there has been a lack of ready-to-use solutions on the market. Kora thus emerged with the following features: · Complete fee payment for transactions; · Use any Token (including stablecoins) to pay fees; · Transfer signing operations to a secure environment.
