Solana Development

Comprehensive skill for building on-chain programs and client applications on Solana.

Core Concepts

Account Model

Solana uses an account-based model where all state is stored in accounts:

• Programs are stateless, executable accounts (marked executable: true)
• Data accounts store state; every data account has an owner program
• Only the owner program can modify an account's data or debit its lamports
• Accounts must be rent-exempt (hold ≥ 2 years rent in lamports) or be garbage-collected

Key account fields: pubkey, lamports, data, owner, executable, rent_epoch.
