anchor-decoder

A procedural macro to help with decoding Solana accounts and instructions for programs written with the Anchor framework.

Note: this tool relies on IDLs generated by Anchor 0.30.0. Fortunately, there's a CLI command to help convert legacy IDLs to the new format.

Usage

Add the crate to your Cargo.toml, and point the macro at your IDL:

use anchor_decoder::anchor_idl;

#[anchor_idl("./idl.json")]
pub const ID: Pubkey = crate::ID;

You can create separate crates for each program. You can also call the macro multiple times in the same files by using separate modules.

pub mod production {
    use anchor_decoder::anchor_idl;
    #[anchor_idl("./production.json")]

    pub const ID: Pubkey = crate::ID;
}

pub mod staging {
    use anchor_decoder::anchor_idl;
    #[anchor_idl("./staging.json")]

    pub const ID: Pubkey = crate::ID;
}
