Estimating Message Fees

Get the quantity of native gas token to pay to send a message

If you want to know how much AptosCoin to pay for the message, you can call the Endpoint's quote_fee() to get the fee tuple (native_fee (in coin), layerzero_fee (in coin)).

public fun quote_fee(
    ua_address: address,
    dst_chain_id: u64,
    payload_size: u64,
    pay_in_zro: bool,
    adapter_params: vector<u8>,
    msglib_params: vector<u8>
): (u64, u64)
