Program Derived Addresses (PDAs)
A PDA is an address derived from a program ID plus a list of seeds, deliberately chosen so that it has no private key. Only the deriving program can s…

Learn Solana from real code.
Every lesson here is built from excerpts of real, permissively licensed projects in the Solana SuperStack catalog, with permalinks to the exact lines at a pinned commit and a plain-English walkthrough.
Lessons
Cross-Program Invocations (CPIs)
A CPI is one program calling an instruction on another program, such as the Token Program or System Program. The caller passes the accounts the callee…
SPL Tokens: mints, accounts and transfers
Fungible tokens on Solana are accounts owned by the Token Program. A mint account defines supply and decimals, and a token account holds a balance of …
Token-2022 (Token Extensions)
Token-2022 is a separate token program with the same core layout as the original Token Program, plus optional extensions configured when the mint is c…
Escrow patterns
An escrow holds assets in a program-controlled account, usually a token account whose authority is a PDA, until agreed conditions are met. The usual l…
Staking and reward accrual
Program-level staking usually means locking tokens or NFTs in a PDA-owned vault and tracking per-user state (amount, timestamps, reward debt) in a PDA…
NFTs with Metaplex
Most Solana NFTs follow Metaplex standards. Token Metadata attaches a metadata account to a supply-1 mint, and Metaplex Core is a newer single-account…
Compressed NFTs and state compression
Compressed NFTs store a hash of each asset in a concurrent Merkle tree account instead of in separate accounts, which makes minting millions of assets…
Oracles: Pyth and Switchboard
Programs can't fetch off-chain data, so oracles publish it into accounts the program reads. A Pyth consumer passes a price update account into the ins…
Solana Pay
Solana Pay is a URL standard for requesting payments. A transfer request encodes recipient, amount, SPL token and a unique reference public key, and a…
Blinks and Solana Actions
A Solana Action is an HTTP API. GET returns metadata (title, icon, buttons), and POST receives the user's account and returns a serialized transaction…
AI agents on Solana
Agent projects give an LLM a set of tools (functions) that read chain state or build and sign transactions, usually with a dedicated, limited-balance …
Building and sending transactions from a client
A transaction bundles instructions, a recent blockhash and signatures. Clients fetch a recent blockhash, add instructions (often including compute-bud…
Anchor account constraints
In Anchor, the #[derive(Accounts)] struct is where most security lives. Constraints such as init, mut, has_one, seeds/bump, constraint = ... and close…

What to build
Idea pages built from the shape of the catalog: where strong projects are scarce, which stacks dominate each category, and a starter path through real modules.
