GM! We offer teams free access to high-performance Solana RPC/data streaming infrastructure throughout the @colosseum hackathon and after!
🧚♂️ Want to keep building for free? Join RPC Fast Infrastructure Sidetrack on @superteam: $10,500 in RPC infrastructure credits will be distributed across 21 selected teams.
How it works: Use our infra and share your journey with the ecosystem. The strongest teams with the most engagement will be rewarded with 1-2 months of low latency RPC and gRPC infrastructure access 👇

⚡️ Good news — we now track landing rate and latency for QUIC sendTransactionFast.
How it works: We keep these transactions in memory and monitor their status in the background, so this doesn’t add any overhead to the transaction sending path or affect sending speed.
Track your QUIC sendTransactionFast transactions and their landing metrics in the RPC Fast dashboard.
Ukrainians builders on Solana! Join for rewards 👇

Aperture TxStream now supports Solana v1 transactions. The maximum transaction size is now 4096 bytes, up from 1232.
Transaction V1 just got activated on mainnet-beta at the start of epoch 1035, September 15.
We’ve updated the TxStream proto to properly detect and handle v1 transactions. If you’re using Aperture TxStream, make sure to update your client to the latest version:
crates.io/crates/aperture-gr…
The update introduces:
• TRANSACTION_VERSION_V1 enum.
• New transactionConfig field.
Example of a v1 transaction: gist.github.com/VladStarr/6b…
Even if your app doesn't send V1 transactions, the activation may still affect how your app processes transactions. We recommend reviewing the changes and compatibility requirements in the Solana Foundation guide:
solana.com/upgrades/larger-t…
Transaction V1 activation on mainnet-beta is moving to the start of epoch 1035, expected Sept 15 at ~1:20 AM UTC.
Teams across the ecosystem told us they needed more time to test and integrate V1 support. We listened.
How to get ready:
- V1 is live on devnet, test your integration now.
- Compute budgets in V1 are set using a new transaction config. Compute budget instructions still work on legacy and V0 but no-op in V1.
- App developers: even if you don't plan to send V1 transactions, some changes may impact your app. Review the guide below.
Details: solana.com/upgrades/larger-t…
GM! Reminder to those who use or plan to use our Stream plan:
❗️ Aperture TxStream is no longer available on the Stream plan and is exclusive to the Aperture plan, as was initially planned ❗️
Yellowstone gRPC is still available. If you need TxStream, consider switching to the Aperture plan.
Thank you for being with us!

GM! We introduce quarterly discounts – save 10% by subscribing to any paid plan for 3 months.
👉 Stacks with promo codes for new subscriptions or plan upgrades.
📍 Terms:
• You can still downgrade at any time. The new plan will apply at the end of your paid period (3 months).
• For upgrades, the new plan is active immediately.
• If you purchased a 3-month subscription, you can switch to monthly payments later, and vise versa – just choose your preferred mode at checkout during the next payment
Update: ⚡️ Some of your DeFi queries just got faster - meet Quark
Recently, we built Quark, our in-house solution that accelerates eligible getProgramAccounts calls. Eligible requests get routed through it automatically - everything else just flows through the normal RPC path.
To qualify, your request needs:
1. encoding: base64
2. non-empty filters
3. commitment: processed / confirmed / finalized(default)
4. standard dataSize + memcmp filters (mint filters must decode to exactly 32 bytes; memcmp.bytes may be base58 or base64.)
Supported protocols: @Pumpfun PumpSwap, @orca_so Whirlpools, @MeteoraAG DAMM v2 & DLMM, @Raydium AMM v4/CLMM/CPMM, Jupiter v6, @humidifi pool accounts, @kamino Lending.
⚠️ Note: you may need to query with the specific filters shown in our docs to get the speedup.
Read full details + per-protocol filter shapes here:
docs.rpcfast.com/rpc-fast-sa…
❗️Aperture gRPC is now officially deprecated. Please use Aperture TxStream instead.
TxStream is our optimised gRPC protocol for receiving decoded Solana transactions directly from the shred pipeline, with ALT resolved and real-time transaction simulation.

Your Solana HFT stack just got another edge.
RPC Fast has integrated Surge by @RaidenSolanaWtf – bringing raw validator shreds into our infrastructure for even faster, lower-level data pipelines.
👉 raiden.wtf
Whether you're running searchers, trading bots, HFT setups, or real-time analytics, every millisecond counts. More shred sources → lower latency → better performance.
Available in FRA geo. Read more about data streaming: docs.rpcfast.com/rpc-fast-sa…
