The Solana Foundation announced the launch of “Kora,” which focuses on fee payment and remote signing, and is paired with standardized settings and toolchains of the Solana Keychain, allowing development teams to manage transaction fees, Token policies, and signing environments in a more consistent manner.

The Solana Foundation officially launched “Kora” a few hours ago, aiming to enable transactions in the ecosystem to support fee payment or pay transaction fees with selected Tokens, and to support outsourcing signing tasks to a secure environment.
The post pointed out that the launch of Kora was due to the previous lack of “modern, standardized” fee sponsorship and remote signing solutions. Although the Solana account model itself provides feasibility, there were no ready-made tools available in the market, which is why it was developed and provided by the foundation.

Core functions: fee payment, any Token payment, and remote signing
The unlocking features of Kora include three main aspects:
First, “fully sponsored transaction fees”, which means that the designated fee wallet pays the transaction costs on behalf of the user.
Second, “paying transaction fees with any Token” includes the use of stablecoins as a means of payment.
Third, “remote signing” transfers the signing process to a secure environment, such as Turnkey or commonly used AWS KMS by enterprises.
The Solana Foundation mentioned that Kora supports 6 types of remote signing schemes and provides a mechanism for monitoring fund balances and metrics, which can promptly alert when the fee wallet funds are insufficient, reducing the risk of transaction failures.
Cost Management and User Experience
Overall, Kora's fee payment mechanism can support user experience optimization at the “application level”: for example, having the service provider pay the transaction fees, allowing end users to complete transactions “free of charge” in specific situations; or paying transaction fees with stablecoins to reduce cost uncertainty caused by fluctuations in the underlying token prices.
On the other hand, remote signing allows enterprises to manage keys and signing processes within their existing security infrastructure. Coupled with fund balance monitoring and metrics, it benefits the operations team in grasping the status of expenditure cash flow and risks.
The release of Kora fills the gap of “lack of standard tools” in the ecosystem, allowing for sustainable observation of the integration and effectiveness of various applications in fee payment and signature management.
