Storage functions¶

KeyDeposit¶

Stores the current deposit that will be taken when saving a key.

Python¶

result = substrate.query(
    'Keystore', 'KeyDeposit', []
)

Return value¶

'u128'

Keys¶

Keys that are currently stored.

Python¶

result = substrate.query(
    'Keystore', 'Keys', [
    'AccountId',
    (
        'scale_info::12',
        (
            'P2PDiscovery',
            'P2PDocumentSigning',
        ),
    ),
]
)

Return value¶

{
    'deposit': 'u128',
    'key_type': ('ECDSA', 'EDDSA'),
    'purpose': ('P2PDiscovery', 'P2PDocumentSigning'),
    'revoked_at': (None, 'u32'),
}

LastKeyByPurpose¶

Storage used for retrieving last key by purpose.

Python¶

result = substrate.query(
    'Keystore', 'LastKeyByPurpose', [
    'AccountId',
    (
        'P2PDiscovery',
        'P2PDocumentSigning',
    ),
]
)

Return value¶

'scale_info::12'

Constants¶

MaxKeys¶

Value¶

Python¶

constant = substrate.get_constant('Keystore', 'MaxKeys')

Errors¶
