DeFi on Solana

DeFi programs on Solana hold assets in PDA-owned token accounts and move them with CPIs into the Token Program. Escrow, staking, swaps and lending all reuse the same building blocks: PDAs, token accounts, checked arithmetic and strict account validation.

Reference: Solana docs: Tokens

Lessons

Escrow patterns Advanced
Staking and reward accrual Advanced
Program Derived Addresses (PDAs) Beginner
Cross-Program Invocations (CPIs) Intermediate
SPL Tokens: mints, accounts and transfers Intermediate
Oracles: Pyth and Switchboard Advanced
