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&lt;'info&gt;
Checks:
  • is_signer is true

​
SystemAccount<‘info>

Represents a native Solana account owned by the System Program. 
pub user: SystemAccount&lt;'info&gt;

​
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&lt;'info&gt;
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>
