Module 0x1::balance

A balance module provides access to external balance-handling functionality, which is contained within the Substrate layer in our case.

If a script wants to execute a transfer, a transaction which contains the script must receive two parameters:

• signer - A proof that the account has signed the transaction.

• cheque_amount - How many funds is the signer account allowing a script to transfer from that account. The provided amount remains in the signer account if the script doesn't perform any transfer.

• Function transfer

• Function cheque_amount

• Function total_amount

Function transfer

Perform a transfer.

Returns true in case the transfer executed successfully. An error indicates insufficient funds in the provided cheque.

public fun transfer(src: &signer, dst: address, cheque_amount: u128): bool

native public fun transfer(src: &signer, dst: address, cheque_amount: u128): bool;

Function cheque_amount

Get the current cheque amount for the address.

The cheque amount is the amount the address is allowed to transfer within the current executing context.

public fun cheque_amount(account: address): u128

native public fun cheque_amount(account: address): u128;

Function total_amount

Get the total balance for the address.

public fun total_amount(account: address): u128

native public fun total_amount(account: address): u128;
