This is the stable v1 release for Hats Protocol!
Hats Protocol v1 is a fully permissionless and immutable contract, with no upgradeability, adjustable parameters, or owner of any kind.
What's New
This newest release of Hats Protocol adds a single change: it inherits from Multicallable.sol to enable EOAs to batch multiple calls to Hats.sol into a single transaction.
This unlocks a number of new possibilities for apps to create better experiences for users, such as easier hat tree creation, forking other trees and templates, maturing a tree from testnet to mainnet, and making bulk edits to an existing tree.
No other changes have been made to the protocol. The ABI and IHats interface are otherwise exactly the same.
Other Notes
- v1.hatsprotocol.eth has been updated to point to the new v1 contract address (see below).
