Genesis Programs#

Trident allows you to use Cross Program Invocation of both Native and SBF programs.

Native#

In case of multiple programs within the Anchor Workspace. Make sure that all of the programs you would like to call Cross Program Invocation to are included in the initial state of the Fuzz Test Environment.

Important

Source code below:

fuzzing_program_callee is included in the ProgramTestClientBlocking
fuzzing_program_caller is included in the ProgramTestClientBlocking

// test_fuzz.rs

fn fuzz_iteration<T: FuzzTestExecutor<U> + std::fmt::Display, U>(
    fuzz_data: FuzzData<T, U>
) {
    let fuzzing_program_callee = FuzzingProgram::new(
        PROGRAM_NAME_CALLEE,
        &PROGRAM_ID_CALLEE,
        processor!(convert_entry!(entry_callee)),
    );

    let fuzzing_program_caller = FuzzingProgram::new(
        PROGRAM_NAME_CALLER,
        &PROGRAM_ID_CALLER,
        processor!(convert_entry!(entry_caller)),
    );

    let mut client =
        ProgramTestClientBlocking::new(
            &[fuzzing_program_callee, fuzzing_program_caller],
            &[]
        ).unwrap();

    let _ = fuzz_data.run_with_runtime(&mut client);
}

SBF#

In case of SBF targets, compiled or dumped from whatever cluster. You can also use these within the Fuzz Tests.

Tip

If you want to obtain Program from Mainnet use

# -u m specifies to dump from mainnet
solana program dump -u m <PROGRAM_ID> <PROGRAM_NAME>.so

Important

To include the SBF target in the Fuzz Test for CPI, specify address and path to the program in the Trident.toml.
Including these types of programs will lead to performance decline of Trident.

[[fuzz.programs]]
address = "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s"
program = "metaplex-program/metaplex-token-metadata.so"

Genesis Accounts#

Trident allows you to include Accounts with data in base64 format.

Tip

If you want to obtain Account with base64 data format, use

# -u m specifies to dump from mainnet
solana account -u m <ADDRESS> --output json

Important

To include desired accounts in the fuzz testing environment, add then using the Trident.toml.

[[fuzz.accounts]]
address = "6YG3J7PaxyMnnbU67ifyrgF3BzNzc7cD8hPkqK6ATweE"
filename = "tests/accounts/core_bridge_mainnet/guardian_set_5_mock.json"
