fn flush(env: soroban_sdk::Env, token_address: soroban_sdk::Address)Returns the memo string stored in this contract
fn get_memo(env: soroban_sdk::Env) -> soroban_sdk::StringReturns the factory contract address
fn get_factory(env: soroban_sdk::Env) -> soroban_sdk::AddressReturns the relayer address
fn get_relayer(env: soroban_sdk::Env) -> soroban_sdk::AddressInitialize contract with memo, relayer, and factory addresses
fn __constructor(
env: soroban_sdk::Env,
memo: soroban_sdk::String,
relayer_address: soroban_sdk::Address,
factory_address: soroban_sdk::Address,
