Parsed Streams and the Parsed Events API replace the legacy Enhanced Transactions API and webhooks Plus, they're more cost effective: - Parsed Events API: 10 credits/request (10x less) - Parsed Streams: 1 credit/event (same as webhooks) Pricing: helius.dev/docs//billing/cre…

Point the Parsed Events API at a transaction to get: - A summary: "wallet X swapped 5 SOL for PUMP via Jupiter" - Every argument with a name (e.g. in_amount) - Every account with a role (e.g. authority) - All SOL and token transfers Works for 3,600+ programs via our IDL catalog

Last week Solana and Allfunds kicked off Project Harmonia. The next evolution of capital and finance is being built: > Allfunds provides a €1.9 trillion funds network > @solana provides the infrastructure and offers compliant privacy
Project Harmonia is open for applications. Allfunds connects 3,300+ asset managers and financial institutions, with €1.9T in assets under administration. Tokenized funds on Solana can now apply to reach them, and funds on Allfunds become accessible on Solana.

Reliability is an infrastructure problem before it is a crypto problem. Latency, routing, and where your edge sits decide what people actually feel when they use an app. Kyle Kloepper, principal engineer at @helius and formerly at Cloudflare, joined @nocircuit on The Stack to talk about how years of internet-scale networking work shaped the way he thinks about Solana.

.@helius got rejected fifty times before the first yes. “It can’t just be adding a feature or a new button to an existing thing. It has to be something that people fundamentally don’t agree on today. Peter Thiel’s question, what truth do you believe in that nobody else believes in?” “With Helius, I got rejected, I don’t know, 50 times or something before I got my first yes.” “Every rejection just fired me up more to be like, you’re just stupid. And I will make more money than you and prove you’re wrong.” @mert of @helius at Solana Summit Serbia

“Crypto itself has existed since Bitcoin, technically speaking, which has been over a decade. However, programmable blockchains that scale, that are actually usable, have really only existed for maybe three years max.” “People point to AI, but most people seem to not understand that AI has been around for over 50 years. People have been trying to work on AI since Alan Turing, since before computers even existed.” “We’re only about two to three years into what’s possible on-chain.” @mert of @helius at Solana Summit Serbia

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

Only care about one wallet and one token? Combine it with the tokenAccounts filter Works in historical replay too so you can backfill 24 hrs of token activity
