Account types

Reference for Anchor’s account wrapper types

Anchor provides strongly-typed account wrappers for common Solana account patterns.

Account<‘info, T>

Wrapper for program-owned accounts with automatic validation and deserialization.

pub data: Account<'info, MyData>

Checks:

• Account owner is the current program
• Account discriminator matches type T
• Account data deserializes to type T

Signer<‘info>

Verifies an account signed the transaction.

pub authority: Signer<'info>

Checks:

• is_signer is true

SystemAccount<‘info>

Represents a native Solana account owned by the System Program.

pub user: SystemAccount<'info>

Program type

Verifies an account is an executable program.

pub system_program: Program<'info, System>

Checks:

• Account is executable
• Account key matches expected program ID

UncheckedAccount<‘info>

Raw AccountInfo with no automatic checks.

/// CHECK: Safe because we only read the key
pub unchecked: UncheckedAccount<'info>

Always add a /// CHECK: comment explaining why no validation is needed.

InterfaceAccount<‘info, T>

For Token-2022 compatibility.

use anchor_spl::token_interface::TokenAccount;

pub token_account: InterfaceAccount<'info, TokenAccount>
