Notes on Solana infrastructure, latency & speed.
Deep dives on shreds, gRPC streaming, co-location, and the engineering behind landing transactions first. Written by the team running the nodes.

GUIDE
What Are Solana Shreds? The Fastest Way to Read On-Chain Data
Standard RPC shows you transactions after a block is confirmed. Shreds show them while it's still propagating - the foundation of low-latency Solana trading.

DEEP DIVE
Stake-Weighted QoS (SWQoS) on Solana, Explained
SWQoS lets validators hand out ingest bandwidth in proportion to stake, so staked connections land while public endpoints get throttled under load.
HOW-TO
Solana RPC Methods: A Practical Reference
The Solana JSON-RPC methods you'll actually use, what each one does, where they bite, and when to reach for gRPC or shreds instead.
GUIDE
Solana Geyser Plugins, Explained
Geyser is the plugin interface that lets account, transaction, and slot data flow out of a validator as it is processed. Here is how it works.
GUIDE
Copy-Trading on Solana: The Infrastructure Behind It
Copy-trading bots watch a target wallet and mirror its trades. The hard part isn't the logic, it's seeing the trade and landing yours before the edge is gone.

Solana Arbitrage Bot Infrastructure: What You Actually Need
An arbitrage bot is mostly infrastructure, not strategy. Here's the ingest, decode, and execution stack a Solana arbitrage bot actually needs.

rpc edge vs Helius vs Triton: Solana Infrastructure, Compared
Three strong Solana providers, three different centers of gravity. A fair head-to-head for teams choosing infrastructure for trading and HFT.

Jito on Solana: Bundles, Tips, and MEV Explained
How the Jito Block Engine, bundles, tips, and the auction work, and how MEV is contested on Solana, for searchers and trading teams.

Best Solana RPC Providers in 2026: A Buyer's Comparison
There is no single best Solana RPC provider, only the right one for your job. Here is the framework to pick yours, and an honest read on the main players.
HOW-TO
Why Solana Transactions Fail (and How to Land Them)
Most Solana transactions don't fail on-chain, they vanish before they arrive. Here's why they drop and how to land them.

Solana Commitment Levels: Processed vs Confirmed vs Finalized
A plain reference to Solana's commitment levels, what each one guarantees, and which to pick for reads, writes, settlement, and HFT signal.

Building an HFT Data Pipeline on Solana: A Reference Architecture
From shred ingestion to landed transaction - a reference architecture for low-latency Solana trading, and where the milliseconds actually hide.
HOW-TO
Landing Transactions on Solana: Leader Paths and the Jito Block Engine
Sending a Solana transaction is easy; landing it fast, in the slot you wanted, is the hard part. How the leader schedule, the TPU, and Jito fit together.
DEEP DIVE
Reading Decoded Transactions Before Confirmation
"First-seen" means acting on a transaction while it's still propagating - before any node calls it confirmed. What that state is, and how to use it safely.
GUIDE
Yellowstone gRPC vs Standard RPC, Explained
Polling RPC asks the node "anything new?" on a loop. Geyser-based gRPC pushes updates the instant they happen. How the two models differ - and when to use each.
INFRA
Why RPC Polling Can't Keep Up With HFT on Solana
Polling a Solana RPC node asks the same question on a loop and pays in latency. Where the milliseconds go - and the architecture that removes them.
