Thank you @italoacasas for bringing us together. I’m excited to be contributing to RPC at @JupiterExchange.

The @JupiterExchange team keeps leveling up. Every addition pushes the bar higher. Excited to have @espicodes, @0xnaga, @GroovieGer88951, and @_fanatid join the team; it's hard to match this much Solana brain power in one room. Lots in store... 🚢🚢

Had to make it super official with the @JupiterExchange affiliation. I needed that logo.

The @jump_firedancer validator accepts receiving bundles from an external source. In this case @jito_sol bundles. Excited to see how this kind of composability plays out. github.com/firedancer-io/…

On Friday, I couldn't load 500 pubkeys into a Solana account using Borsh—just one copy blew the stack. 🧨 Today, using @anza_xyz Pinocchio, I loaded 6,000 pubkeys by directly mutating the account data slice. The only real limit now is Solana’s 10MB max account size—around 300k

1/ SIMD-0341 proposes protocol-level account compression. Sounds amazing — smaller state, lighter validators, faster snapshots. But after reading it, I think it just moves the problem off-chain. 🧵

Off to the airport for @SolanaCrossroad after an incredible @SuperteamAE SEZ. I first came to Dubai for the Founders Villa in October. I leave today with my Emirates ID. Whole family’s coming back in September to stay. I’ve been building on Solana since 2021 — from hacker

Proud to be part of the @JupiterExchange RPC team. We shipped this in the first two weeks. You’re not ready for what’s coming in month one. Jupiter understands: your UX is only as good as your lowest-level infra. That’s why they built an in-house RPC team—to own the stack end

@JupiterExchange’s new tx infra (blue) lands transactions in the same slot with near-impossible consistency. On top of that, we get privacy which removes a huge chunk of frontrun risk for users. Rolling out next week. (orange and green are external providers)

Always good to poke around the @anza_xyz repository once in awhile. You are bound to find a goodie. Looking forward to trying out new program testing framework.

Long time coming but with the dip it was time to become a Tensorian @tensor_hq Down on the trade. Up on the vibes. HODL.

folks loved our business cards at #decentralcon. I want to say they stopped by the booth for us but I know it was because of these fly cards.

The most impressive presentation at #HackerHouseBarcelona was by @AckeeBlockchain. A solana testing framework in rust called trdelnik.

This isn’t just a Geyser plugin with a bigger slot cache. It’s a re-architected strategy for persisting and replaying massive volumes of Solana event history. Built with a Kafka-like consumer and cursor model. Designed for real scale. It was a privilege to contribute feedback —

Good news! @solana 's read layer just got a massive upgrade: Introducing Fumarole Fumarole is a streaming service explicitly built with data completeness in mind. It pauses the data stream upon disconnection and starts streaming again when you tell it to. You won't miss
