- Solana engineers introduced Kora, a modular fee system that allows applications to sponsor transactions or accept fees in stablecoins and other SPL tokens.
- The system abstracts gas fees at the application level, expanding Solana suitability for next-generation consumer and financial applications.
Solana engineers have introduced a modular fee system designed to give developers greater flexibility in how transaction costs are handled across decentralized applications. The initiative, announced by the Solana Foundation on X, centers on Kora, a fee relayer and signing node that removes the requirement for users to hold SOL to interact with applications on the network.
As the Solana Foundation detailed, Kora allows applications to either sponsor transaction fees entirely or accept payments in alternative SPL tokens, including stablecoins such as USDC, or other tokens such as BONK. The feature separates transaction execution from SOL ownership and aims to make onboarding simpler and reduce friction for end users, particularly in consumer-facing applications where managing native gas tokens can be a barrier.
Kora can also operate at the infrastructure layer, enabling developers to define how fees are paid without having to change the underlying Solana protocol. This approach aligns with broader industry efforts to abstract gas mechanics at the application level, while preserving Solana’s high-throughput and low-latency transaction environment.
Kora of Solana Audits and Security Progress
According to a detailed thread Solana engineer @dev_jodee shared on X, Kora includes more than 20 granular fee-payer controls across system programs, SPL tokens, and Token-2022 extensions. The controls let developers specify which actions the relayer can authorize—for example, enabling account creation while restricting token transfers or approvals.

The system also supports scalable signing architecture, enabling multiple fee payers under a single node at the same time, which also allows teams to separate fee payers by use case, balance transaction load across keys, and isolate operational risk.
Solana Expanding Functionality and Ecosystem Impact
By abstracting transaction fees, Kora supports a more seamless user experience and allows applications to operate without requiring users to hold SOL—reinforcing Solana’s push toward consumer-ready infrastructure. In addition, as we previously reported, Coinbase has opened instant trading access to roughly 100 million users through its Solana integration, expanding global reach for assets issued on the network and increasing potential distribution for Solana-based applications.
As of press time, Solana (SOL) is trading at $125.57, however with a decrease of **0.34% ** over the past 24 hours and **0.56% ** over the past week, according to Coin Market Cap data. See SOL price chart below.
