Proud to share that I have officially graduated from the @solanaturbine Builders Cohort (Q3 2026)! Spent the last few weeks pushing limits, mastering the Solana stack, and building production-ready Web3 applications. Ready for what's next!

Solana just got 51 builders stronger From the prereqs to getting your capstones out on demo day, we saw how much work you put in over the last two months. So give yourselves a proper pat on the back 💚 We're proud of every one of you, and we’ll be cheering for your wins as you keep growing in this ecosystem. And you’re part of the Turbin3 Tribe now. That doesn’t come with an end date.

Anchor Visualizer is a high-performance static analysis engine built in Rust that reverse-engineers abstract macros into interactive 2D/3D instruction maps, ordered dependency graphs, and precise CPI call paths — with zero deployment required.

...when my knowledge helps others. Thank you to @solanaturbine for the high praise.
Closing out week three with some appreciation for @SergZen, @AndreExilien, and @abhayk_01 with plenty happening across the Q3 forge, we’re taking a moment to share what these three have been up to, including a returning wingman andre🧵

Just shipped a production-ready universal Solana indexer for the bounty — built in Rust 🦀 It automatically adapts to ANY Anchor IDL. No manual schema definitions, no migrations when your program changes.

The nastiest bug: solana-sdk 4.x split into sub-crates. CommitmentConfig moved, Account type exists in two incompatible versions simultaneously. Lesson: always check what the compiler error actually says, not what you think the import path should be

Stack: Rust + Tokio + Axum + sqlx + PostgreSQL docker compose up --build — one command, everything running. Full README with architecture overview, API examples, and decision rationale. Code: github.com/SergZen/solana-un… Happy to discuss Solana infra architecture

Built a Solana program indexer in Rust for the SST bounty. It indexes on-chain transactions, decodes Anchor instructions via IDL, stores everything in PostgreSQL, and serves it through a REST API — all in one `docker compose up`. Here's what I learned

The REST API has two endpoints: `GET /tx/{signature}` — full transaction with decoded instructions `GET /tx?ix_name=buy&signer=7xKX...` — paginated list with filters. Signer filter runs a JSONB containment query over the accounts array using a GIN index.
