Ecosystem Headlines

Smart Contracts

• Our friends at Supercolony presented openbrush on the first substrate seminar of the year. OpenBrush is a library for smart contract development on ink!. It is to Polkadot what OpenZeppelin is to Solidity. It has all the standardized contracts with their extensions and a collection of modifiers. This seminar aims to focus on how to build a full-scope production project using OpenBrush.
  
• Contracts pallet - The contracts pallet now automatically collects deposits from the caller for the storage created instead of having the contract manage rent. See the original PR that enables this.

Substrate

• Types replacement - You can use these traits to facilitate writing runtime constants: frame_support::traits::{ConstU32, ConstU64}. See this PR for some examples.
• Preimage Pallet - pallet_preimage is a new pallet for storing the hash of some data, useful alongside the democracy pallet to upload the reasoning behind a certain proposal or any other pallet that may require the pre-image of some data.
• Uniques Pallet - A new feature has been added to pallet_uniques to improve UX, making it easier to query asset classes.
• Deterministic chain spec writing - Writing a chain spec is now deterministic after this modification.
