I suppose there can be some value in unlocking company equity, but placing freezable contract on a public blockchain? I suppose that might make audits easier or something. However, might as well put full trust into the person with the freeze key, would likely be a lot cheaper. Every stablecoin has the freeze function so far, and that underpins DeFi, which has become sizable. I'm probably just dumb.

Proxied versions of standard contracts are also proposed by Openzeppelin: https://docs.openzeppelin.com/upgrades-plugins/1.x/writing-u... https://github.com/OpenZeppelin/openzeppelin-contracts-upgra... For KYC you'll need to implement your own ERC20 compatible token with some checks in the transfer functions. The CMTA is the Swiss contract reference and proposes one: https://github.com/CMTA/CMTA20
