CrowdloanRewards¶

Calls¶

add¶

Adds all accounts in the additions vector. Add may be called even if the pallet has been initialized.

Attributes¶

Name	Type
additions	`Vec<(RemoteAccountOf<T>, RewardAmountOf<T>, VestingPeriodOf<T>)>`

Python¶

call = substrate.compose_call(
    'CrowdloanRewards', 'add', {
    'additions': [
        (
            {
                'Ethereum': '[u8; 20]',
                'RelayChain': 'AccountId',
            },
            'u128',
            'u64',
        ),
    ],
}
)

associate¶

Associate a reward account. A valid proof has to be provided. This call also claim the first reward (a.k.a. the first payment, which is a % of the vested reward). If logic gate pass, no fees are applied.

The proof should be:

proof = sign (concat prefix (hex reward_account))

Attributes¶

Name	Type
reward_account	`T::AccountId`
proof	`ProofOf<T>`

Python¶

call = substrate.compose_call(
    'CrowdloanRewards', 'associate', {
    'proof': {
        'Ethereum': '[u8; 65]',
        'RelayChain': (
            'AccountId',
            {
                'Ecdsa': '[u8; 65]',
                'Ed25519': '[u8; 64]',
                'Sr25519': '[u8; 64]',
            },
        ),
    },
    'reward_account': 'AccountId',
}
)

claim¶

Claim a reward from the associated reward account. A previous call to associate should have been made. If logic gate pass, no fees are applied.

Attributes¶

No attributes

Python¶

call = substrate.compose_call(
    'CrowdloanRewards', 'claim', {}
)

initialize¶

No attributes

Python¶

call = substrate.compose_call(
    'CrowdloanRewards', 'initialize', {}

Attributes¶

Name	Type
at	`MomentOf<T>`

Python¶

call = substrate.compose_call(

populate¶

Populate pallet by adding more rewards.

Each index in the rewards vector should contain: remote_account, reward_account, vesting_period.

Can be called multiple times. If an remote account already has a reward, it will be replaced by the new reward value.

Can only be called before initialize.

                'Ethereum': '[u8; 20]',
                'RelayChain': 'AccountId',
            },
            'u128',
            'u64',
        ),
    ],
}
