Your token feed shouldn’t miss transfers
Normal SPL transfers never put the mint in the list of account keys, so gRPC accountInclude filters never match it
LaserStream's new matchMints flag matches pre/post balances to fix this

See transactions the moment a validator commits to executing them
That's 5-50 milliseconds BEFORE transactions are turned into shreds, and the earliest a tx can be observed on Solana
All delivered via one new WebSocket subscription: preconfSubscribe

Get a wallet's balance at any point in time
The new balance-at endpoint returns a wallet's exact SOL or SPL token balance at a given date or slot
How much USDC did a wallet hold at 19:20 on Jan 10, 2025?
Now it's a single call
Ideal for PnL, charts, snapshots, and cost basis

@therealricoy +1 to this. Early on we had some pretty specific features requests and they pulled an all nighter to have it live the next day
We haven’t made feature requests in a long time because they keep shipping their stuff just works
The @Helius team is on another level

Helius has shipped so much gamechanging stuff that we take it for granted

we are formally proposing reducing SOL inflation, faster
read below if interested in how it works
the comeback has started
Big Solana news:
The Light Protocol team is joining Helius to help build Solana's most complete ZK privacy layer.
Private payments, markets, and finance -- at Solana scale.
Fully composable, fully onchain, fully open-source.

helius is the only solana-exclusive RPC for a reason
that focus allows us to ship APIs like this for solana devs that are an order of magnitude better than anything else
if 100x lower latency & fewer API calls weren't enough, we've now increased bandwidth 10x & reduced prices

NEW:
getTransactionsForAddress is now 5x cheaper and 10x more powerful
- Get up to 1000 full txs per request (prev 100)
- Pay 10 credits per 100 returned txs (prev 50)
Solana Agave 4.0 is here!
This release brings:
• Huge acceleration of retransmit with XDP
• Lower latency replay
• Expanded cryptographic support
• Stake Program v5 + higher minimum stake
• SBPFv3 program support
• Multiple Alpenglow preparation updates

I just built an advanced forensics terminal powered by getTransfersByAddress.
It identifies rings of connected wallets and displays the assets transferred between them. Instead of clicking through tables of transactions, I can just query thousands of transfers instantly.
These are the connected wallets who made over 4,000 SOL off of a memecoin a few days ago. I tracked where the funds went.

this seems to be one of the most loved things we've ever released on Solana
every transfer on solana, indexed and exposed through flexible params (time-based, amount-based, token-based etc)
flows, analytics, accounting, and stables with 50x less code and 10x lower latency
