⚡️Aperture TxStream just got richer real-time simulation results.
With the new simulation_config field, you can inspect predicted transaction effects before confirmation – with only the simulation data you actually need.
Use it to:
• Analyze swaps and arbitrage: use token balance deltas to estimate token inflows, outflows and trade outcomes.
• Power copy-trading and wallet alerts: identify predicted balance changes for accounts you follow.
• Monitor account changes: detect predicted account creation, closure and ownership changes.
• Understand complex DeFi transactions: trace inner instructions across swaps, lending protocols and multi-program routes.
• Debug failed transactions: inspect simulation logs and program return data to understand execution outcomes.
• Track compute usage: measure consumed compute units for transaction analysis and optimization.

A few important notes:
• Enable only the simulation fields you need to reduce processing overhead and payload size, helping keep latency low.
• Simulation results are predictions, not confirmed execution data.
• Existing users: update both aperture-grpc-proto and aperture-grpc-client to v0.6.1. If you generate your own client, regenerate it from the updated txstream.proto.

Reminder: we've recently introduced Quark - DeFi Query Accelerator for Solana! Read more details in our blog post 👉
rpcfast.com/blog/quark-solan…
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.

⚡️ 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.

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.

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!
