Vesting¶

Calls¶

force_vested_transfer¶

Force a vested transfer.

The dispatch origin for this call must be Root.

source: The account whose funds should be transferred.
target: The account that should be transferred the vested funds.
schedule: The vesting schedule attached to the transfer.

Emits VestingCreated.

NOTE: This will unlock all schedules through the current block.

Attributes¶

target	`<T::Lookup as StaticLookup>::Source`

Python¶

call = substrate.compose_call(
    'Vesting', 'force_vested_transfer', {
    'schedule': {
        'locked': 'u128',
        'per_block': 'u128',
        'starting_block': 'u32',
    },
    'source': {
        'Address20': '[u8; 20]',
        'Address32': '[u8; 32]',
        'Id': 'AccountId',
        'Index': 'u32',
        'Raw': 'Bytes',
    },
    'target': {
        'Address20': '[u8; 20]',
        'Address32': '[u8; 32]',
        'Id': 'AccountId',
        'Index': 'u32',
        'Raw': 'Bytes',
    },
}
)

merge_schedules¶

Merge two vesting schedules together, creating a new vesting schedule that unlocks over the highest possible start and end blocks. If both schedules have already started the current block will be used as the schedule start; with the caveat that if one schedule is finished by the current block, the other will be treated as the new merged schedule, unmodified.

NOTE: If schedule1_index == schedule2_index this is a no-op. NOTE: This will unlock all schedules through the current block prior to merging. NOTE: If both schedules have ended by the current block, no new schedule will be created and both will be removed.

Merged schedule attributes: - starting_block: MAX(schedule1.starting_block, scheduled2.starting_block, current_block). - ending_block: MAX(schedule1.ending_block, schedule2.ending_block). - locked: schedule1.locked_at(current_block) + schedule2.locked_at(current_block).

The dispatch origin for this call must be Signed.

schedule1_index: index of the first schedule to merge.
schedule2_index: index of the second schedule to merge.

Name	Type
schedule1_index	`u32`
schedule2_index	`u32`

)

vest¶

Unlock any vested funds of the sender account.

The dispatch origin for this call must be Signed and the sender must have funds still locked under this pallet.

Emits either VestingCompleted or VestingUpdated.

Events¶

VestingCompleted¶

An [account] has become fully vested.

Attributes¶

Name	Type	Composition
account	`T::AccountId`	`AccountId`

VestingUpdated¶

The amount vested has been updated. This could indicate a change in funds available. The balance given is the amount which is left unvested (and thus locked).

Attributes¶

Name	Type	Composition
account	`T::AccountId`	`AccountId`
unvested	`BalanceOf<T>`	`u128`

Storage functions¶

StorageVersion¶

Storage version of the pallet.

New networks start with latest version, as determined by the genesis build.

Python¶

result = substrate.query(
    'Vesting', 'StorageVersion', []
)

Return value¶

('V0', 'V1')

Vesting¶

Information regarding the vesting of a given account.

Python¶

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

Return value¶

[{'locked': 'u128', 'per_block': 'u128', 'starting_block': 'u32'}]

Constants¶

MaxVestingSchedules¶

Value¶

Python¶

constant = substrate.get_constant('Vesting', 'MaxVestingSchedules')

MinVestedTransfer¶

The minimum amount transferred to call vested_transfer.

Value¶

100000000000000000000

Python¶

constant = substrate.get_constant('Vesting', 'MinVestedTransfer')

Errors¶

AmountLow¶

Amount being transferred is too low to create a vesting schedule.

AtMaxVestingSchedules¶

The account already has MaxVestingSchedules count of schedules and thus cannot add another one. Consider merging existing schedules in order to add another.

InvalidScheduleParams¶

Failed to create a new schedule because some parameter was invalid.

NotVesting¶

The account given is not vesting.

ScheduleIndexOutOfBounds¶

An index was out of bounds of the vesting schedules.
