Implements an XCM executor `WeightTrader`, facilitating fee payments in any asset that can be exchanged for a native asset. A few constraints need to be observed: - `buy_weight` and `refund` operations must be atomic, as another weight trader implementation might be attempted in case of failure. - swap credit must be utilized since there isn’t an account to which an asset of some class can be deposited with a guarantee to meet the existential deposit requirement. Also, operating with credits enhances the efficiency of the weight trader - https://github.com/paritytech/polkadot-sdk/pull/1677 related PRs: - (depends) https://github.com/paritytech/polkadot-sdk/pull/2031 - (depends) https://github.com/paritytech/polkadot-sdk/pull/1677 - (caused) https://github.com/paritytech/polkadot-sdk/pull/1847 - (caused) https://github.com/paritytech/polkadot-sdk/pull/1876 // DONE: impl `OnUnbalanced` for a `fungible/s` credit // DONE: make the trader free from a concept of a native currency and drop few fallible conversions. related issue - https://github.com/paritytech/polkadot-sdk/issues/1842 // DONE: tests --------- Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com> Co-authored-by: Liam Aharon <liam.aharon@hotmail.com>
