Attribute Macro light_system_accounts

Source 
#[light_system_accounts]
Expand description

Adds required fields to your anchor instruction for applying a zk-compressed state transition.

§Usage

Add #[light_system_accounts] to your struct. Ensure it’s applied before Anchor’s #[derive(Accounts)] and Light’s #[derive(LightTraits)].

§Example

Note: You will have to build your program IDL using Anchor’s idl-build feature, otherwise your IDL won’t include these accounts.

ⓘ
#[light_system_accounts]
#[derive(Accounts)]
pub struct ExampleInstruction<'info> {
    pub my_program: Program<'info, MyProgram>,
}

This will expand to add the following fields to your struct:

  • light_system_program: Verifies and applies zk-compression state transitions.
  • registered_program_pda: A light protocol PDA to authenticate state tree updates.
  • noop_program: The SPL noop program to write compressed-account state as calldata to the Solana ledger.
  • account_compression_authority: The authority for account compression operations.
  • account_compression_program: Called by light_system_program. Updates state trees.
  • system_program: The Solana System program.
