* HoldReason: Improve usage `HoldReason` was switched recently to use the `composite_enum` attribute that will merge the enums from all pallets in the runtime to `RuntimeHoldReason`. `pallet-nis` was still requiring that the variant was passed as constant to call `hold`. The proper implementation is to use the `HoldReason` from inside the pallet directly when calling `hold`. This is done by adding a `RuntimeHoldReason` as type to the `Config` trait and requiring that `Currency` is using the same reason. Besides that the pr changes the name `HoldIdentifier` in `pallet_balances::Config` to `RuntimeHoldReason`. * Update frame/nis/src/lib.rs Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Review comment * Fixes --------- Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io>
Transaction Payment Pallet
This pallet provides the basic logic needed to pay the absolute minimum amount needed for a transaction to be included. This includes:
- weight fee: A fee proportional to amount of weight a transaction consumes.
- length fee: A fee proportional to the encoded length of the transaction.
- tip: An optional tip. Tip increases the priority of the transaction, giving it a higher chance to be included by the transaction queue.
Additionally, this pallet allows one to configure:
- The mapping between one unit of weight to one unit of fee via [
Config::WeightToFee]. - A means of updating the fee for the next block, via defining a multiplier, based on the
final state of the chain at the end of the previous block. This can be configured via
[
Config::FeeMultiplierUpdate]
