Today, we are releasing the biggest RPC and data upgrade for Solana devs in years. getTransactionsForAddress combine getSignaturesForAddress and getTransaction into one you can now search history in reverse order as well as filtering by slot ranges and dates you do not need to traverse backwards from the most recent transaction anymore oh, also all archival calls are now 10x faster enjoy!
today, Solana changes forever we've solved the biggest data/RPC problem that exists solana historical/archival data — has now been redesigned quick context: today when you query historical data (getBlock/getTransaction/getSignaturesForAddress), it hits Google BigTable this is i) slow, ii) expensive, iii) inflexible for queries e.g., you physically can not get the first tx for a Solana address without looping back endlessly from the latest tx for busy addresses, this can take thousands of RPC calls — extremely slow, expensive, and annoying also, imagine you wanted to get the most recent 100 txs for an address, how do you do it? you first hit getSignaturesForAddress to get all the tx signatures and then call getTransaction on each tx to get its details — this can take 1,001 RPC calls in the worst case not anymore we have built a new distributed archival storage system that is 1,000x faster, more flexible, and more scalable the best part? we're introducing a new API method: getTransactionsForAddress with this method, you can now: i) combine getSignaturesForAddress and getTransaction calls into just 1 call instead of 1,000 ii) you can search in reverse order without needing to traverse iii) you can search historical transactions by time and slot ranges (e.g. get me all the txns from January 5th, 2025 until February 5th, 2025) what's more: - getBlock calls are now 10x faster - getTransaction calls are now 10x faster - getSignaturesForAddress calls are now 10x faster 10x lower latency, 100x fewer RPC calls, and 1000x less code enjoy! docs below
getTransactionsForAddress search Solana, in any order, from/to any slot/time range — combine getTxn with gSFA in one call 1000x less time, 100x fewer RPC calls, 10x lower latency
guide to happiness: 1. stop checking price 2. get off twitter 3. use @heliuslabs' getTransactionsForAddress to query transaction history 10x faster than alternative endpoints

The Solana Virtual Machine (SVM) will stand as one of the most significant contributions in the history of blockchains. However, there are conflicting definitions, and people cry about the lack of a magical spec. So, I cleared things up. Available on the @heliuslabs blog

gmino @heliuslabs Every line of Kamino Lend is open source, verifiably built, and now discoverable directly in the Orb Explorer Don’t trust. Verify.
Join us live with @heliuslabs CEO @0xMert_, @SolanaFndn Growth @chloejiani, and @SolanaFndn DeFi Growth Lead @ramzyyalii! Our $HSDT Director and @PanteraCapital General Partner @CosmoJiang will explore how Helius and the Solana Foundation are collaborating with top Solana projects to enhance the ecosystem! Monday November 3, 2025 @ 2pm ET / 6pm UTC

btw a cool but relatively hidden feature of Orb is that you can view markets, vol, and liquidity per a given token on Solana (sometimes the API misses prop AMMs but will fix that)

Here's what's happening if you're new to solana:
Why is suddenly everyone talking about LaserStream? 🧵 1/7

yep
Since launching LaserStream in June, we’ve shipped a set of upgrades that make it faster, simpler, and more flexible for production use. Some of my favorite ships include: - Lower latency: Thanks to our shreds product, e2e delivery is faster across regions with improved p50/p95 and more stable p99. -40x faster JS gRPC client: Handle automatic reconnects, historical replay, and eliminate perf bottlenecks with the LaserStream SDK. -Two new regions: Los Angeles (LAX) and London (LON) are now live. Choose from a total of 9 regional endpoints. -Enhanced WebSockets: Enhanced WSS now run on the same infra used by LaserStream. Better reliability, lower latency, no syntax changes. -Devnet on all paid plans: Spin up and test LaserStream workflows on devnet without changing plans or infra. -New plans: We released 3 accessible data add-ons so you can get data at a predictable cost. What's coming? - Longer replay window - Decoded shreds What else do you want to see from @heliuslabs to improve your data streaming experience on Solana?

incredible sequence of events here join the many builders and traders getting a massive boost from laserstream today do not take our word for it though, try it with no risk to you first
tldr: Laserstream is faster and more reliable than anything else out there.

We just added 2 new LaserStream endpoints: London (LON) and Los Angeles (LAX) That's now 9 total regional endpoints Fast, reliable, globally available Enjoy

devs have already cooked up an improved schema for getTransactionsForAddress' cold storage p99 reduced from 200ms to 15ms client proximity (network) is now the bottleneck next up: stop serving JSON faster

This is huge the new Orb explorer by Helius allows you to view the files of a Verified program (first time a Solana explorer having feature parity with the verified contracts feature on EVM chains) orb.helius.dev/address/9fhQB… in contrast, Solscan / Official Explorer allows you to view only the Verification status and repo URL.
one of the biggest knocks on solana has been its open source culture on EVM, it's the norm to look at the source code of the contracts you interact with this was not the case on Solana, so we added it verification, code structure, and multisig details so users are informed
manlets, switch your default explorer to orb thank you for your attention to this matter
today we are releasing Orb a human-readable Solana block explorer with AI explanations and a time machine for historical transaction searching link at the end of the video enjoy!

Tried it already and it is super fast. no more multiple api calls. Neat!
