Preparation for https://github.com/paritytech/polkadot-sdk/pull/3935 Changes: - Add some `default-features = false` for the case that a crate and that dependency both support nostd builds. - Shuffle files around of some benchmarking-only crates. These conditionally disabled the `cfg_attr` for nostd and pulled in libstd. Example [here](https://github.com/ggwpez/zepter/pull/95). The actual logic is moved into a `inner.rs` to preserve nostd capability of the crate in case the benchmarking feature is disabled. - Add some `use sp_std::vec` where needed. - Remove some `optional = true` in cases where it was not optional. - Removed one superfluous `cfg_attr(not(feature = "std"), no_std..`. All in all this should be logical no-op. --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io>
Assets Parachain
Implementation of Asset Hub, a blockchain to support generic assets in the Polkadot and Kusama networks. Asset Hub was formerly known as "Statemint".
Asset Hub allows users to:
- Deploy promise-backed assets, both fungible and non-fungible, with a DOT/KSM deposit.
- Set admin roles to manage assets and asset classes.
- Register assets as "self-sufficient" if the Relay Chain agrees, i.e. gain the ability for an asset to justify the existence of accounts sans DOT/KSM.
- Pay transaction fees using sufficient assets.
- Transfer (and approve transfer) assets.
- Interact with the chain via its transactional API or XCM.
Asset Hub must stay fully aligned with the Relay Chain it is connected to. As such, it will accept the Relay Chain's governance origins as its own.
See the article on Asset Hub as common good parachain for a higher level description.
Wallets, custodians, etc. should see the Polkadot Wiki's Integration Guide for details about support.
