Compiling Contracts

This guide shows you how to compile your Aztec contracts into artifacts ready for deployment and interaction.

Prerequisites​

  • An Aztec contract written in Aztec.nr
  • aztec installed
  • Contract project with proper Nargo.toml configuration

Compile your contract​

Compile your Noir contracts to generate JSON artifacts:

aztec compile

This outputs contract artifacts to the target folder.

Use generated interfaces​

The compiler automatically generates type-safe interfaces for contract interaction.

Import and use contract interfaces​

Use generated interfaces instead of manual function calls:

contract FPC {
    use dep::token::Token;

    #[external("private")]
    fn fee_entrypoint_private(amount: Field, asset: AztecAddress, secret_hash: Field, nonce: Field) {
        assert(asset == storage.other_asset.read());
        Token::at(asset).transfer_to_public(context.msg_sender(), context.this_address(), amount, nonce).call(&mut context);
        FPC::at(context.this_address()).pay_fee_with_shielded_rebate(amount, asset, secret_hash).enqueue(&mut context);
    }
}
warning

Do not import generated interfaces from the same project as the source contract to avoid circular references.

Next steps​

After compilation, use the generated artifacts to:

  • Deploy contracts with the Contract class from aztec.js
  • Interact with deployed contracts using type-safe interfaces
  • Import contracts in other Aztec.nr projects
