Storage functions¶

Claims¶

Python¶

result = substrate.query(
    'Claims', 'Claims', ['[u8; 20]']
)

Return value¶

'u128'

Preclaims¶

Pre-claimed Ethereum accounts, by the Account ID that they are claimed to.

Python¶

result = substrate.query(
    'Claims', 'Preclaims', ['AccountId']
)

Return value¶

'[u8; 20]'

Signing¶

The statement kind that must be signed, if any.

Python¶

result = substrate.query(
    'Claims', 'Signing', ['[u8; 20]']
)

Return value¶

('Regular', 'Saft')

Total¶

Python¶

result = substrate.query(
    'Claims', 'Total', []
)

Return value¶

'u128'

Vesting¶

Vesting schedule for a claim. First balance is the total amount that should be held for vesting. Second balance is how much should be unlocked per block. The block number is when the vesting should start.

Python¶

result = substrate.query(
    'Claims', 'Vesting', ['[u8; 20]']
)

Return value¶

('u128', 'u128', 'u32')

Constants¶

Prefix¶

Value¶

'Pay DOTs to the Polkadot account:'

Python¶

constant = substrate.get_constant('Claims', 'Prefix')

Errors¶

InvalidEthereumSignature¶

Invalid Ethereum signature.

InvalidStatement¶

A needed statement was not included.

PotUnderflow¶

There's not enough in the pot to pay out some unvested amount. Generally implies a logic error.

SenderHasNoClaim¶

Account ID sending transaction has no claim.

SignerHasNoClaim¶

Ethereum address has no claim.

VestedBalanceExists¶

The account already has a vested balance.
