Storage functions

---

Accounts

The balance of a token type under an account.

NOTE: If the total is ever zero, decrease account ref account.

NOTE: This is only used in the case that this module is used to store balances.

Python

result = substrate.query(
    'Tokens', 'Accounts', [
    'AccountId',
    {
        'CategoricalOutcome': (
            'u128',
            'u16',
        ),
        'CombinatorialOutcome': None,
        'ForeignAsset': 'u32',
        'ParimutuelShare': (
            'u128',
            'u16',
        ),
        'PoolShare': 'u128',
        'ScalarOutcome': (
            'u128',
            ('Long', 'Short'),
        ),
        'Ztg': None,
    },
]
)

Return value

{'free': 'u128', 'frozen': 'u128', 'reserved': 'u128'}

---

Locks

Any liquidity locks of a token type under an account. NOTE: Should only be accessed when setting, changing and freeing a lock.

Python

result = substrate.query(
    'Tokens', 'Locks', [
    'AccountId',
    {
        'CategoricalOutcome': (
            'u128',
            'u16',
        ),
        'CombinatorialOutcome': None,

            ('Long', 'Short'),
        ),
