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(
'OrmlTokens', 'Accounts', [
'AccountId',
{
'AUSD': None,
'ForeignAsset': 'u32',
'LocalAsset': 'u32',
'Native': None,
'Staking': ('BlockRewards', ),
'Tranche': ('u64', '[u8; 16]'),
None: 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(
'OrmlTokens', 'Locks', [
'AccountId',
{
'AUSD': None,
'ForeignAsset': 'u32',
'LocalAsset': 'u32',
'Native': None,
'Staking': ('BlockRewards', ),
'Tranche': ('u64', '[u8; 16]'),
None: None,
},
]
)
Return value¶
[{'amount': 'u128', 'id': '[u8; 8]'}]
Reserves¶
Named reserves on some account balances.
Python¶
result = substrate.query(
'OrmlTokens', 'Reserves', [
'AccountId',
{
'AUSD': None,
