Stack: Rust + Tokio + Axum + sqlx + PostgreSQL

Happy to discuss Solana infra architecture

[Serg Zen @SergZen]

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

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

[Serg Zen @SergZen]

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.
