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¶

'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', [

'P2PDiscovery',
'P2PDocumentSigning',
),
]
)
Return value¶
'scale_info::12'
Constants¶
