Solana developers and businesses are getting a new tool as the Kora fee relayer promises to streamline the way users experience transaction costs on the network.
Solana Foundation Introduces Kora for Seamless Pricing and Signatures
of solana foundation announced this week Colaa new rate relayer and signing node designed to make Solana apps easier to use, more secure to operate, and more flexible for builders. Additionally, it directly targets long-standing issues such as who pays transaction fees, how they are paid, and where signing takes place.
For the uninitiated, transaction fees are small costs paid to process actions on the blockchain, such as: Solana. For more sophisticated builders, managing these rates at scale can quickly become complex and operationally burdensome. Kora aims to remove that friction by standardizing payment and remote signing practices.
Make transaction fees invisible to end users
Kora allows apps to fully sponsor transaction costs, allowing users to interact with Solana applications without holding anything back. sol not at all. However, this does not mean that the fees will disappear. Instead, the app allows you to pay with any token, including stablecoins such as: USDCThis changes the traditional requirement that users first purchase network-native assets to begin using the service.
The Solana Foundation explained that Kora was created because there was no modern standard way to handle paid sponsorships. remote transaction signingEven if Solana's account model already technically enables such a pattern. Kora is now filling that gap as an out-of-the-box solution for teams that need predictable infrastructure.
A specific example is: Solana Game Onboarding. Imagine a gaming app that allows new players to quickly get started on-chain. Kora also allows games to pay transaction fees on behalf of users and charge those costs in in-game tokens. The flow feels more like a regular web or mobile app, as players don't see a wallet pop-up asking them to SOL.
Kora provides standards RPC server CLI to sign and pay charges for wallets charged using solana key chain. However, this setup allows teams to centrally manage balances while integrating with their existing Solana infrastructure and security practices.
This design is in line with broader industry trends. According to electric capitaldeveloper activity across cryptocurrencies is increasingly focused on user experience rather than just raw performance metrics. In that context, Transaction fee abstraction has emerged as an important pillar of mainstream-enabled applications.
Strengthen signature and operational management security
Beyond fees, Kora also talks about how transactions are signed. Signing is the process of authorizing a transaction using a private key, which traditionally was often located on a local server. Kora allows teams to move their signing operations to a secure environment that: AWS KMS or other hosted key management services to reduce direct key exposure.
In fact, Kora Price Relay supports six remote signers and publishes metrics that alert your team when funds are running low. Additionally, this observability helps operations teams avoid failed user actions due to wallet depletion. This is especially important for consumer-facing apps and exchanges.
For developers, Kora comes with a standard RPC server, command line utilities, and simple configuration files. Teams can specify which programs or user accounts are allowed, validate incoming transactions, define pricing rules for various token standards, and implement custom policy logic that fits their business model.
Security was also a focus. The Solana Foundation states: Runtime validation Kora is fully audited and tested, adding an additional layer of assurance for companies and protocols that want to rely on Kora for production workloads. However, teams are still expected to integrate Kora into their own security and monitoring stacks.
Outlook for the user-friendly Solana app
Combining reward sponsorships allows for flexible payments in assets such as: Fees paid in USDCand solidified aws kms signature Kora aims to make Solana applications feel like mainstream digital products. Additionally, it provides a path for enterprises to abstract away the complexity of blockchain while retaining the benefits of a high-performance network.
In summary, Kora provides Solana builders with a standardized way to pay fees, manage signatures, and enforce detailed policies, potentially lowering the barrier to entry for millions of new users.
