Solana Releases New SDK Versions and Accepts Fee Change Proposal

On July 23, 2026, the Solana engineering teams announced several updates, including new versions of the Agave and Firedancer frameworks and numerous program software development kits (SDKs). Key updates include Agave v4.3.0-alpha.2 and v4.2.0-beta.2, and Firedancer v1.1.2 and v0.1102.40201, alongside updates to various SDKs integral to Solana’s functionality.

Among the notable changes, the Resource and Inclusion Fees Solana Improvement Document has been accepted, which alters how base fees are allocated and burned on the network. From now on, a portion of the base fees—specifically, 2500 lamports—will be allocated to validators, while the remaining fees will depend on the requested compute units and will be burned. This introduces a protocol-level buy-and-burn mechanism related to SOL, aiming to enhance the economic model around network usage.

The updates also include improvements to validator clients and RPC (Remote Procedure Call) operations, focusing on program deployment efficiency and data archiving methods. Agave is refining its program deployment command-line interface (CLI) to ease the process for developers and improve memory allocation for proof-of-history records, which are vital for establishing a chronological order of transactions on the Solana network. Firedancer is enhancing its epoch boundary procedures, which are essential for managing validator rewards and setting schedules for upcoming epochs.

Additional program libraries and testing tools were updated as well. Highlights include the Subscription Program allowing users to immediately cancel subscriptions and new associated token account helper functions, crucial for many Solana applications.

Several community resources emerged alongside the technical updates: Helius launched an RPC benchmarking tool, while contributors shared insights on zero-knowledge proofs and Anchor framework releases. The continuous evolution of these tools and frameworks emphasizes Solana's commitment to building a robust and efficient ecosystem for developers.
