impl TransactionApi

Source

pub fn spend_local( &self, amount: Amount, beneficiary: Beneficiary, ) -> StaticPayload<SpendLocal>

Propose and approve a spend of treasury funds.

§Dispatch Origin

Must be [Config::SpendOrigin] with the Success value being at least amount.

§Details

NOTE: For record-keeping purposes, the proposer is deemed to be equivalent to the beneficiary.

§Parameters
  • amount: The amount to be transferred from the treasury to the beneficiary.
  • beneficiary: The destination account for the transfer.
§Events

Emits [Event::SpendApproved] if successful.

Source

pub fn remove_approval( &self, proposal_id: ProposalId, ) -> StaticPayload<RemoveApproval>

Force a previously approved proposal to be removed from the approval queue.

§Dispatch Origin

Must be [Config::RejectOrigin].

§Details

The original deposit will no longer be returned.

§Parameters
  • proposal_id: The index of a proposal
§Complexity
  • O(A) where A is the number of approvals
§Errors
  • [Error::ProposalNotApproved]: The proposal_id supplied was not found in the approval queue, i.e., the proposal has not been approved. This could also mean the proposal does not exist altogether, thus there is no way it would have been approved in the first place.
Source

pub fn spend( &self, asset_kind: AssetKind, amount: Amount, beneficiary: Beneficiary, valid_from: ValidFrom, ) -> StaticPayload<Spend>

Propose and approve a spend of treasury funds.

§Dispatch Origin

Must be [Config::SpendOrigin] with the Success value being at least amount of asset_kind in the native asset. The amount of asset_kind is converted for assertion using the [Config::BalanceConverter].

§Details

Create an approved spend for transferring a specific amount of asset_kind to a designated beneficiary. The spend must be claimed using the payout dispatchable within the [Config::PayoutPeriod].

§Parameters
  • asset_kind: An indicator of the specific asset class to be spent.
  • amount: The amount to be transferred from the treasury to the beneficiary.
  • beneficiary: The beneficiary of the spend.
  • valid_from: The block number from which the spend can be claimed. It can refer to the past if the resulting spend has not yet expired according to the [Config::PayoutPeriod]. If None, the spend can be claimed immediately after approval.
§Events

Emits [Event::AssetSpendApproved] if successful.

Source

pub fn payout(&self, index: Index) -> StaticPayload<Payout>

Claim a spend.

§Dispatch Origin

Must be signed

§Details

Spends must be claimed within some temporal bounds. A spend may be claimed within one [Config::PayoutPeriod] from the valid_from block. In case of a payout failure, the spend status must be updated with the check_status dispatchable before retrying with the current function.

§Parameters
  • index: The spend index.
§Events

Emits [Event::Paid] if successful.

Source

pub fn check_status(&self, index: Index) -> StaticPayload<CheckStatus>

Check the status of the spend and remove it from the storage if processed.

§Dispatch Origin

Must be signed.

§Details

The status check is a prerequisite for retrying a failed payout. If a spend has either succeeded or expired, it is removed from the storage by this function. In such instances, transaction fees are refunded.

§Parameters
  • index: The spend index.
§Events

Emits [Event::PaymentFailed] if the spend payout has failed. Emits [Event::SpendProcessed] if the spend payout has succeed.

Source

pub fn void_spend(&self, index: Index) -> StaticPayload<VoidSpend>

Void previously approved spend.

§Dispatch Origin

Must be [Config::RejectOrigin].

§Details

A spend void is only possible if the payout has not been attempted yet.

§Parameters
  • index: The spend index.
§Events

Emits [Event::AssetSpendVoided] if successful.
