Building Solana programs with Anchor or native Rust starts by installing Anchor or setting up a native Rust project, then defining accounts, PDAs, and CPIs for your program logic. Anchor provides macros that simplify account handling and serialization, while native Rust offers lower-level control. Both approaches support token operations, DeFi, and NFT use cases with testing and deployment workflows included.

PDAs (Program Derived Addresses) are deterministic accounts controlled by your program, enabling state management without private keys. CPIs (Cross-Program Invocations) allow your program to call other Solana programs. Both are core to building composable DeFi and NFT applications; Anchor abstracts much of their complexity through macros, while native Rust requires explicit account and instruction serialization.

Anchor includes built-in testing and deployment workflows within its framework. Both Anchor and native Rust projects support testing through Rust's standard test harness. Anchor's deployment tools handle on-chain verification; native Rust projects require manual CLI commands. Both approaches satisfy production deployment verification requirements.

Choose native Rust when you need fine-grained control over account serialization, error handling, or have performance-critical code where macro overhead matters. Anchor is faster for rapid development and safer for complex account interactions. Native Rust is preferred for specialized security contexts or when integrating with existing Rust ecosystems that don't depend on Anchor.

Error handling in Solana programs requires explicit validation of account ownership, lamport transfers, and instruction data. Anchor provides error enums and custom error codes; native Rust requires manual error type definitions. Both approaches must validate account types, check PDA derivation, and prevent unauthorized CPI calls to ensure security in token and DeFi operations.

Yes, account serialization is fundamental in Solana development. Anchor handles serialization through derive macros and the `Account` type, abstracting complexity. Native Rust requires manual serialization using `Borsh` or other formats. Understanding serialization is essential for designing state layouts, especially for token programs and multi-account transactions.
