this is one of the gnarliest engineering challenges that exists on Solana

so we solved it for everyone, scale

historical balances for any wallet, for any token, at any time

yes you read that correctly

it took years but it finally exists

[Helius @Helius]

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

Full circle moment! First met @swen_sjn @ananas_light during at a hackathon 4 years ago while @dlabvc now we get to work together. Up only

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.

quick timelapse of solana's popular programs over the years

using nothing but a single getTransactionsForAddress endpoint by Helius

reading Solana data is now this easy

[mert @mert]

markets are information systems

if p2p info is broadcasted to all, then participants change behavior and information isn't fully reflected

solana solved perf, but crypto can't scale until this information problem is fixed

luckily, we've found a way

trillions soon

Big IBRL week

We deployed archival v2.1 to our US clusters

Here are the results (p95 latency):
- getTransaction: 7ms -> 1ms
- getTransactionsforAddress: 350ms -> 30ms (!!)
- getBlock: 50ms -> 35ms

What changed?
1. Re-worked the transaction storage layer from the ground up
2. Implemented our own rpc protocol (over tcp) for storage <-> proxy communication

EU and APAC clusters will deploy next week. Enjoy!

Disclaimer: Latencies are measured from within our network. To observe similar numbers, call our new Gatekeeper edge network from EWR or NY.

LOL cant make this up

no one works harder than @Helius to make sure your business runs smoothly while we take all the punches on your behalf

[mert @mert]

block explorers will be dead by EOY

before: click on static spreadsheet tables endlessly

now: talk to the chain in english. ask specifically for what you want. generate visuals live.

we are calling it @LanaAI, invite only as we iterate

only on Solana; invite codes below

just another day at helius

@nathan_liow @heliuslabs @mert @nick_pennie @owen_venter @kneeecolesf welcome!

[nick | helius.dev @nick_pennie]

last year, @heliuslabs re-built the RPC API from first principles

we split it into distinct systems, each one optimized for performance from end-to-end: historical, account state, etc

the result? everything is faster. much faster.

for example, our getProgramAccounts is ~200 ms faster than any competitor

gPA comparison pictured below, helius in orange

[mert @mert]

Helius by far the highest IBRL score of the top validators on Solana

we do not play short term games

I did not start this to milk marginal bucks, but to make Solana the arena for all finance

the only validator in the top that comes close to us is bitwise, also run by us

IBRL

[mert @mert]

the new helius getTransactionsForAddress is up to 20x faster than existing RPCs

this is the most insane thing we've ever released

you can make your app faster literally this second with a single line of code change

if you don't believe me, ask claude to benchmark like below

[Andrew @ann_droo]

Live look of @bmannella1 and team

[mert @mert]

you can now send crypto via your block explorer

next time you ask someone for money, send them an orb link of your address instead of just pasting the raw text

then all they have to do is press send

[Solana @solana]

JUST IN: @heliuslabs rolls out getTransactionsForAddress, a new Solana history API for sorting, filtering, and querying every transaction by wallet address 🔥

[Robbie @robbie689]

Finally a full-time manlet ... 👨‍🦲

beyond thrilled to join @heliuslabs on the BD team working with @deepatalwar1 @ShivanshuMadan and @mert

Have been in Solana since 2021 and every year I get more convinced Helius will continue to widen the gap in powering the best teams. A few things that I've noticed over the years:

- Every dev I talk to is blown away by the speed + support -- zero bad experiences

- The pace this team ships at is actually absurd

- After my first day and seeing what’s coming next, I’m like 20x more bullish (I was already turbo bullish)

Absolutely fired up to shove internet capital markets onchain at lightspeed

LFG

Holy fuck.

Our SOL staking rewards import 100x faster now.

Switched from Quicknode -&gt; Helius.

Requests that took 10 seconds+ now are sub 100ms.

Helius goated. 🙇‍♂️ @nick_pennie 🙇‍♂️

@OkimotoKyle @markcecchini as a former FA, the problem isn't that an FA is valuable. A good one 100% is.

The problem is that there are way too many, and most normal ppl don't have the skills to choose a good one. As a result they get scammed into high fees/high fee products and suboptimal setups.
