[SWIP-39 re-run] Upgrade MetaVault Factory to Enable Permissionless MetaVaults

In this proposal, we are seeking StakeWise DAO approval to deploy new MetaVault Factory contracts on Ethereum and Gnosis Chain, allowing permissionless creation of MetaVaults with/without ERC-20 tokenization and whitelist functionality.

This will enable stakers and service providers to automatically distribute stake across multiple Vaults at once while managing a single position instead of many.

The new Factory contracts have been audited by Statemind.

Note that this is the re-run of a successful SWIP-39, initiated to add a corner case optimization.
