HatsSignerGate v2

Changes

This is a major release, with many new features and improvements.

• No more dedicated factory. Instances are now deployed from the Zodiac Module Proxy Factory.
• All HSGs are now Multi, ie they can be configured with multiple signers hats
• Full compatibility with other Safe & Zodiac modules, ie HSG is now a Zodiac modifier to which Safe modules and a guard can be attached
• Simpler and more legible valid signer logic
• Stronger protections against signers changing Safe state, including explicit protection against signers changing the fallback handler
• Delegatecalls are now restricted to a set of approved target contracts, for improved state safety while retaining ability to batch calls via MultiSend
• HSG can be be detached from the Safe, or the Safe can be migrated to a new HSG (by the owner)
• Removed the maxSigners parameter, which in practice only complicated initial configuration unnecessarily
• Uses transient storage for significant gas savings
• Signer permissions can optionally be claimed on behalf of accounts wearing a signersHat, for improved automation and onboarding UX
• HSG can be locked, preventing any changes to configuration

Hats Signer Gate v1.1-beta

Changes

• Fixed a small bug in the Factory where the _deployMultiHatsSignerGate() function was erroneously set to public rather than internal, allowing users to bypass the safety check that helps ensure that MHSG is not deployed for a Safe with existing modules.

Deployments

See deployment parameters for more details on each deployment.
