     * Creates transaction which sends whole account balance. Does two things:
     * 1. `amount = accountBalance - maxFeePerGas * gasLimit`
     * 2. `maxPriorityFeePerGas = maxFeePerGas`
     *
     * Every eth block sets a fee for all its transactions, called base fee.
     * maxFeePerGas indicates how much gas user is able to spend in the worst case.
     * If the block's base fee is 5 gwei, while user is able to spend 10 gwei in maxFeePerGas,
     * the transaction would only consume 5 gwei. That means, base fee is unknown
     * before the transaction is included in a block.
     *
     * By setting priorityFee to maxFee, we make the process deterministic:
     * `maxFee = 10, maxPriority = 10, baseFee = 5` would always spend 10 gwei.
     * In the end, the balance would become 0.
     *

     * payments for services have specific amounts, and not *the whole amount*.
