Mollusk

A lightweight SVM testing harness that executes Solana program instructions directly without spinning up a validator or simulated runtime. Mollusk loads a program's compiled SBF binary and processes individual instructions against a minimal account set, providing fast unit-test-level feedback. It supports both native and BPF programs, making it ideal for rapid iteration on instruction logic without the overhead of solana-test-validator or full Bankrun setup.

Pruebas (Programas Solana)

The process of validating Solana programs through unit tests, integration tests, and fuzz testing. Common approaches: Rust tests with solana-program-test or LiteSVM (fast, in-process), TypeScript tests with Bankrun or solana-test-validator (end-to-end), and fuzz testing with Trident. Best practice is testing both happy paths and attack vectors (missing signers, wrong owners).

LiteSVM

A lightweight Solana VM for testing Rust programs. LiteSVM provides a minimal SVM environment that executes transactions without the overhead of a full validator. It supports account setup, program deployment, and transaction execution. Faster than solana-program-test and suitable for unit testing individual program instructions.

Rama

solana-program-test

A Rust testing framework in the solana-sdk that provides a BanksClient for in-process program testing. Programs are loaded directly into a test Bank without a network. Supports adding accounts, advancing clock, and processing transactions. Slower than LiteSVM/Bankrun but provides the most accurate runtime behavior for Rust-only test suites.

Multisig

An account controlled by multiple parties requiring M-of-N signatures to authorize actions. On Solana, multisig is implemented by programs like Squads rather than at the protocol level. Use cases: program upgrade authority (require 3-of-5 team members), treasury management, and DAO governance execution.

Framework Anchor

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.

#[account] Macro (Anchor)

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.

#[derive(Accounts)] (Anchor)

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).

Anchor Constraints

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).
