) -> DispatchResult
Create a new crowdloaning campaign for a parachain slot with the given lease period range.
This applies a lock to your parachain configuration, ensuring that it cannot be changed by the parachain manager.
pub fn contribute(
origin: OriginFor<T>,
index: ParaId,
value: <<<T as Config>::Auctioneer as Auctioneer<<T as Config>::BlockNumber>>::Currency as Currency<<T as Config>::AccountId>>::Balance,
signature: Option<MultiSignature>
) -> DispatchResult
pub fn contribute(
origin: OriginFor<T>,
index: ParaId,
value: <<<T as Config>::Auctioneer as Auctioneer<<T as Config>::BlockNumber>>::Currency as Currency<<T as Config>::AccountId>>::Balance,
signature: Option<MultiSignature>
) -> DispatchResult
Contribute to a crowd sale. This will transfer some balance over to fund a parachain slot. It will be withdrawable when the crowdloan has ended and the funds are unused.
Withdraw full balance of a specific contributor.
Origin must be signed, but can come from anyone.
The fund must be either in, or ready for, retirement. For a fund to be in retirement, then the retirement flag must be set. For a fund to be ready for retirement, then:
- it must not already be in retirement;
- the amount of raised funds must be bigger than the free balance of the account;
- and either:
- the block number must be at least
end; or - the current lease period must be greater than the fund’s
last_period.
- the block number must be at least
In this case, the fund’s retirement flag is set and its end is reset to the current block
number.
who: The account whose contribution should be withdrawn.index: The parachain to whose crowdloan the contribution was made.
Automatically refund contributors of an ended crowdloan.
Due to weight restrictions, this function may need to be called multiple
times to fully refund all users. We will refund RemoveKeysLimit users at a time.
Origin must be signed, but can come from anyone.
Remove a fund after the retirement period has ended and all funds have been returned.

end: T::BlockNumber,
verifier: Option<MultiSigner>
) -> DispatchResult
Edit the configuration for an in-progress crowdloan.
Can only be called by Root origin.
Add an optional memo to an existing crowdloan contribution.
Origin must be Signed, and the user must have contributed to the crowdloan.
Poke the fund into NewRaise
Origin must be Signed, and the fund has non-zero raise.

KArg: EncodeLike<ParaId>,
Info on all of the funds.
The number of auctions that have entered into their ending period so far.
Tracker for the next available trie index
The account ID of the fund pot.
This actually does computation. If you need to keep using it, then make sure you cache the value and only call this once.

Returns the current storage version as supported by the pallet.
Returns the on-chain storage version of the pallet as stored in the storage.
The block is being initialized. Implement to have something happen. Read more
The block is being finalized. Implement to have something happen.
This will be run when the block is being finalized (before on_finalize).
Implement to have something happen using the remaining weight.
Will not fire if the remaining weight is 0.
Return the weight used, the hook will subtract it from current weight used
and pass the result to the next on_idle hook if it exists. Read more

Implementing this function on a module allows you to perform long-running tasks that make (by default) validators generate transactions that feed results of those long-running computations back on chain. Read more

The block is being finalized. Implement to have something happen. Read more
Something that should happen at genesis.
The block is being finalized.
Implement to have something happen in case there is leftover weight.
Check the passed remaining_weight to make sure it is high enough to allow for
your pallet’s extra computation. Read more
