On December 23, the Solana Foundation unveiled Kora, a fee relay and signing node designed for the Solana ecosystem. The platform targets a standardized approach to fee delegation and remote signing, addressing a market gap despite the network’s account model. By introducing a common framework, Kora could simplify on-chain interactions for developers and end users.

Key features include the ability to fully delegate transaction fees, pay fees using any token, and offload signature operations to a secure environment. Notably, support for stablecoins and other tokens expands payment flexibility while preserving cryptographic assurances and network security.

By introducing a standardized fee model and remote signing workflow, Kora could alleviate onboarding friction and empower application builders within the Solana ecosystem to experiment with novel monetization schemes under robust governance.
