Solana Changelog: July 9, 2026

Agave, Firedancer, Superbank, Solana Go, and LiteSVM all revealed new variations this week. Engineering work additionally continued throughout validator shoppers, RPC 2.0 protection, language shoppers, and testing frameworks.

Releases

A number of Solana engineering initiatives shipped new launch tags, together with beta and release-candidate variations for core infrastructure and developer tooling.

SIMD dialogue

A brand new Solana Enchancment Paperwork (SIMDs) dialogue proposes including non-obligatory charges for profitable transaction execution. The proposal comes from @cavemanloverboy and focuses on validator incentives.

Validator consumer work

Validator consumer work continued throughout Agave and Firedancer, with modifications targeted on snapshotting, signature verification, packet dealing with, and compilation pace.

• Agave added Wincode serialization for banking stage snapshots. Solana’s present consensus algorithm retains copies of a number of chain histories referred to as forks; when one reaches the suitable peak, validators restart with the brand new root and purge the opposite histories. Agave snapshots the state of all accounts, referred to as the Banking Stage, when forks reset the foundation, and this alteration makes mapping the financial institution snapshot to system reminiscence extra predictable and quicker.
• Agave continued work to optimize SigVerify, the stage that deduplicates transactions and verifies transaction signatures. Efficiency enhancements right here will help transactions get into blocks quicker.
• Agave is working to drop packets quicker in XDP. Providers utilizing XDP will obtain packets by way of QUIC datagrams reasonably than QUIC streams, which may arrive out of order and require extra deduplication; dropping invalid packets from the networking obtain queue quicker leaves extra time for validator logic.
• Firedancer is working to hurry up service compilation. Quicker compilation impacts developer expertise, CI builds and checks, and the way shortly a service could be redeployed after a downtime repair.

RPC 2.0 protection

RPC 2.0 work expanded protection of the Solana HTTP RPC spec throughout Superbank and Cloudbreak. These modifications goal strategies RPC suppliers have to help.

Developer-facing libraries and check frameworks additionally noticed new work, together with React hooks in Equipment and program account testing help in LiteSVM.

• Equipment added transaction planning and sending hooks in @solana/react. The hooks let internet builders bundle transaction planning and sending into React hooks as an alternative of writing uncooked Equipment capabilities, enabling extra dynamic part conduct based mostly on transaction planning and sending state.
• LiteSVM is implementing an interface to the getProgramAccounts technique. The function would let packages check whether or not a program-derived account was efficiently created within the check harness, serving to builders catch incorrect seeds or surprising addresses.

A number of builders and neighborhood contributors shared new proposals, instruments, podcasts, and profiling work.

• @sns proposed including .sol as a top-level area to ICANN in an SNS submit on X.
• @soundsonacid added a brand new profiling function for the seashell check harness in a submit on X.
• @catmcgee is internet hosting a brand new podcast referred to as The Privateness Present, shared by Solana on X.
• @ChainflowSol created a tracker for the bottom validator model qualifying for SFDP in a submit on X.
• @jkdotsol created a brand new disk profiler powered by eBPF in a submit on X.
• @OkohEbina and @a_ix_d posted a brand new Devs at a Bar podcast with @shek_dev in a submit on X.
• @inspiration_gx created an eBPF program that tracks uprobe occasions in Solana’s proof-of-history service in a submit on X.
