On-chain programs: programs/presence

How it works: instructions and accounts

Each instruction handler and the accounts struct it validates, found by reading the Rust source. Links go to the exact line at the pinned commit.

Where the Solana code lives

Source files that import a Solana SDK, ranked by how many Solana APIs they use, with the APIs each one calls. Read them in this order to see how the app talks to the chain.

FileSolana APIs used
sdk/verify-presence/src/index.tsPublicKey, Connection, seeds, findProgramAddressSync, getAccountInfo
programs/presence/src/lib.rsPubkey, seeds, Program, has_one, init_if_needed

Dapp: devnet deploy pending

⏳ Devnet deploy pending — goes live when the devnet wallet is topped up. This fork's own dapp is not deployed yet, so there is no program address or transaction to show. It is queued in dapp-queue.txt; once devnet SOL is available it is deployed, exercised with real devnet transactions, and this section switches to the live dapp at /dapps/facedown/. Until then, the lesson and step-by-step guide below are complete, and you can run it locally with the commands below.

How to run, build and test

These commands come from the repo's own manifests (package.json scripts, Anchor.toml, Cargo, go.mod, Makefile). Check the README for prerequisites and environment variables.
