Apps and art for the whole gang — start anywhere.
Four NFT collections on Solana, a Rust indexer that knows everything about them, and five web apps on top — all built in the open.
| Collection | Supply | Standard | Where |
|---|---|---|---|
| Piggy SOL Gang — ten thousand piggies, straight off the chain | 10,000 | Token Metadata | Magic Eden |
| Piggy Girl Gang — pretty, fierce and dressed for it | 5,000 | Token Metadata | Magic Eden |
| Piggy Gang — same ten thousand piggies, meaner art | 10,000 | Metaplex Core | Magic Eden |
| Pig Mud — something's coming | 2,073 | Token Metadata | Coming soon |
 $PIGGY — the gang's coin |
— | SPL, 9 decimals | Solscan |
Piggy Gang is Piggy SOL Gang wearing new clothes: swapping burns the Token Metadata mint and creates a Metaplex Core asset with the same number. Same piggy, redrawn.
- One spec runs the whole stack. The indexer's OpenAPI file is frozen and hand-written; the explorer vendors a byte-identical copy, generates its typed client from it, and CI fails if the two drift apart. Changing the contract is always two commits — indexer first.
- The frontend shipped before the backend. With nothing configured, the explorer serves committed fixtures through the very same generated client the real API will use. One server-side variable switches it over.
- The database makes two owners unrepresentable. Ownership is stored as intervals with a GiST
EXCLUDEconstraint, so no NFT can have two open owners at once — not by convention, by the schema. - Search is quick. Filtering 10,000 NFTs by traits benches at a p50 of 40 ms on Postgres 17 — 5 ms for text search — against an acceptance bar of 100 ms.
- One package talks to Solana.
@wallet-standard/app, and nothing else: no web3.js, no wallet-adapter, no Buffer polyfill. The browser builds the transaction, the wallet signs it, the app just watches the signature. No key ever reaches a server. - Adding a collection is config, not code. One entry in
collections.tomlplus a mint list. Not a single on-chain address appears in Rust, SQL or tests. - Raffles are free, and provably fair. Entering never costs anything but gas. A Switchboard VRF picks the winner, and anyone can recompute the result from the published proof.
- We kept the art. The collections' original image host went dark. The metadata was re-hosted, the renders were committed, and what survives in these repos may be the only complete copy left.

Next up: Migration — swap your piggy to the new art.
The backend is Rust 1.90 — actix-web, sqlx and Postgres 17.6, deployed on Railway. Every frontend is the same shape on purpose: Next.js 16 App Router, React 19, Tailwind v4, Node 24 and pnpm 11, on Vercel. Clone one and you already know the next.
