Storage functions¶

ConnectedAccounts¶

Mapping from (DID + account identifier) -> (). The empty tuple is used as a sentinel value to simply indicate the presence of a given tuple in the map.

Python¶

result = substrate.query(
    'DidLookup', 'ConnectedAccounts', [
    'AccountId',
    {
        'AccountId20': '[u8; 20]',
        'AccountId32': 'AccountId',
    },
]
)

Return value¶

()

ConnectedDids¶

Mapping from account identifiers to DIDs.

Python¶

result = substrate.query(
    'DidLookup', 'ConnectedDids', [
    {
        'AccountId20': '[u8; 20]',
        'AccountId32': 'AccountId',
    },
]
)

Return value¶

{'deposit': {'amount': 'u128', 'owner': 'AccountId'}, 'did': 'AccountId'}

Constants¶

Deposit¶

The amount of balance that will be taken for each DID as a deposit to incentivise fair use of the on chain storage. The deposit can be reclaimed when the DID is deleted.

Value¶

constant = substrate.get_constant('DidLookup', 'Deposit')

Errors¶

NOTE: this will only be returned if the storage has inconsistencies.
