The use of mathematical proofs to verify that a smart contract's behavior matches its specification for all possible inputs, providing stronger guarantees than testing alone. Techniques include model checking, deductive verification, SAT/SMT solving, and interactive theorem proving. Tools like Halmos (a16z), Kontrol, and Certora Prover enable proving properties like 'total supply never exceeds max.'

A property-based testing approach where developers define invariants (properties that must always hold true) and a fuzzer generates random sequences of function calls attempting to violate them. Unlike unit tests that check specific scenarios, invariant tests explore the state space stochastically. Tools like Foundry invariant testing, Echidna, and Medusa support this approach.
A program analysis technique that explores execution paths using symbolic variables instead of concrete inputs, building mathematical constraints for each branch to identify inputs that trigger specific behaviors. More systematic than fuzzing but computationally expensive due to path explosion. Tools like Halmos, Manticore, and Mythril apply symbolic execution to EVM bytecode.
A formal, structured review of a Solana program's source code, architecture, and deployment configuration by experienced security researchers, aimed at identifying vulnerabilities — including but not limited to the OWASP-equivalent Solana Top 10 (missing signer checks, owner checks, arithmetic errors, etc.) — before mainnet deployment. Reputable Solana-focused audit firms include OtterSec, Ackee Blockchain, sec3 (formerly Soteria), Neodyme, Trail of Bits, and Halborn; most audits produce a severity-rated finding report (critical, high, medium, low, informational) that programs are expected to remediate and publish. A single audit is considered minimum due diligence for programs holding significant user funds; continuous auditing and bug bounties on platforms like Immunefi are considered best practice.

The most popular framework for building Solana programs in Rust. Anchor provides macros (#[program], #[account], #[derive(Accounts)]) that auto-generate boilerplate for account validation, serialization, discriminators, and error handling. It includes a CLI (anchor init/build/test/deploy), IDL generation, and TypeScript client generation. Reduces program code by ~80% compared to native development.
The Anchor macro applied to structs to define on-chain account data layouts. `#[account]` auto-derives Borsh serialization, adds an 8-byte discriminator prefix (SHA-256 of 'account:<Name>'), and implements space calculation. Optional attributes: `#[account(zero_copy)]` for zero-copy deserialization of large accounts.
The Anchor macro that defines the accounts struct for an instruction. Each field specifies an account with validation constraints. Account types include: `Account<'info, T>` (deserialized), `Signer<'info>` (must sign), `Program<'info, T>` (program reference), `SystemAccount<'info>`, and `UncheckedAccount<'info>` (no validation, use carefully).
Declarative validation rules on Anchor account fields. Key constraints: `#[account(mut)]` (writable), `#[account(init, payer=x, space=n)]` (create), `#[account(seeds=[...], bump)]` (PDA validation), `#[account(has_one=field)]` (field equality), `#[account(constraint = expr)]` (custom boolean), `#[account(close=target)]` (close and reclaim rent).
