### Summary This PR introduces new dispatchables to the treasury pallet, allowing spends of various asset types. The enhanced features of the treasury pallet, in conjunction with the asset-rate pallet, are set up and enabled for Westend and Rococo. ### Westend and Rococo runtimes. Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of various asset kinds by specifying the asset's location and ID. #### Treasury Instance New Dispatchables: - `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` - propose and approve a spend; - `payout(SpendIndex)` - payout an approved spend or retry a failed payout - `check_payment(SpendIndex)` - check the status of a payout; - `void_spend(SpendIndex)` - void previously approved spend; > existing spend dispatchable renamed to spend_local in this context, the `AssetKind` parameter contains the asset's location and it's corresponding `asset_id`, for example: `USDT` on `AssetHub`, ``` rust location = MultiLocation(0, X1(Parachain(1000))) asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984))) ``` the `Beneficiary` parameter is a `MultiLocation` in the context of the asset's location, for example ``` rust // the Fellowship salary pallet's location / account FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64))) // or custom `AccountId` Alice = MultiLocation(0, AccountId32(network: None, id: [1,...])) ``` the `AssetBalance` represents the amount of the `AssetKind` to be transferred to the `Beneficiary`. For permission checks, the asset amount is converted to the native amount and compared against the maximum spendable amount determined by the commanding spend origin. the `spend` dispatchable allows for batching spends with different `ValidFrom` arguments, enabling milestone-based spending. If the expectations tied to an approved spend are not met, it is possible to void the spend later using the `void_spend` dispatchable. Asset Rate Pallet provides the conversion rate from the `AssetKind` to the native balance. #### Asset Rate Instance Dispatchables: - `create(AssetKind, Rate)` - initialize a conversion rate to the native balance for the given asset - `update(AssetKind, Rate)` - update the conversion rate to the native balance for the given asset - `remove(AssetKind)` - remove an existing conversion rate to the native balance for the given asset the pallet's dispatchables can be executed by the Root or Treasurer origins. ### Treasury Pallet Treasury Pallet can accept proposals for `spends` of various asset kinds and pay them out through the implementation of the `Pay` trait. New Dispatchables: - `spend(Config::AssetKind, AssetBalance, Config::Beneficiary, Option<ValidFrom>)` - propose and approve a spend; - `payout(SpendIndex)` - payout an approved spend or retry a failed payout; - `check_payment(SpendIndex)` - check the status of a payout; - `void_spend(SpendIndex)` - void previously approved spend; > existing spend dispatchable renamed to spend_local The parameters' types of the `spend` dispatchable exposed via the pallet's `Config` and allows to propose and accept a spend of a certain amount. An approved spend can be claimed via the `payout` within the `Config::SpendPeriod`. Clients provide an implementation of the `Pay` trait which can pay an asset of the `AssetKind` to the `Beneficiary` in `AssetBalance` units. The implementation of the Pay trait might not have an immediate final payment status, for example if implemented over `XCM` and the actual transfer happens on a remote chain. The `check_status` dispatchable can be executed to update the spend's payment state and retry the `payout` if the payment has failed. --------- Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com> Co-authored-by: command-bot <>
