InterfaceAccount (Anchor)

An Anchor account type for CPI interactions with programs that implement a defined interface, allowing a single account type to work with multiple program implementations. For example, InterfaceAccount<'info, TokenAccount> accepts accounts from both the SPL Token Program and Token-2022, since both implement the token interface. This enables programs to be compatible with multiple token standards without separate code paths.

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.

Invocação Entre Programas (CPI)

A mechanism for one program to call another program's instructions during execution. CPIs enable composability—e.g., a DeFi program can call the Token Program to transfer tokens. CPI depth is limited to 4 levels. The caller passes accounts and instruction data, and the callee runs with the same transaction context.

Programa SPL Token

The original Solana Program Library token program (TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA) that implements fungible and non-fungible token operations. It manages mints (token definitions) and token accounts (balances). Core instructions include InitializeMint, MintTo, Transfer, Burn, Approve (delegation), and Revoke. All SPL tokens on mainnet before Token-2022 use this program.

Token-2022 (Extensões de Token)

The next-generation token program (TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb) that extends SPL Token with configurable extensions. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, metadata, and more. Token-2022 is backwards-compatible with SPL Token for basic operations.

#[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.

anchor init / anchor build / anchor test

Anchor CLI commands for project lifecycle. `anchor init <name>` scaffolds a new project (program, tests, Anchor.toml). `anchor build` compiles to SBF and generates the IDL. `anchor test` builds, starts a local validator, deploys, and runs Mocha/Jest tests. `anchor deploy` deploys to the configured cluster. `anchor verify` checks deployed bytecode.

Ferramentas de Devanchor-v031

Anchor v0.31

A major release (March 2025) of the Anchor framework introducing custom discriminators (overriding the default 8-byte discriminator to save transaction space), LazyAccount for on-demand deserialization to reduce compute costs, and stack memory optimizations for init constraints. Positioned as a major milestone on the roadmap toward v1.0.

#[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).
