Protocol Rebranding
Maker has been rebranded as Sky under Maker DAO's Endgame plan. Although there is no significant change after rebranding, Maker founder Rune Christensen claims that this change is to completely transform protocol into decentralisation.
Token Rebranding
As of September 18, DAI and MKR are becoming USDS and SKY as part of the plan. MKR hodlers have the option to exchange 1 MKR for 24k SKY, and DAI hodlers will get USDS at 1:1 ratio. This is optional. Holders of DAI and MKR have the option to keep their original tokens, but in order to receive benefits of new features, exchange is required.
Point on Maker to Sky
Don't ask others to make a decision; it is all up to you to either update your DAI and MKR to new USDS and SKY or keep the original tokens. I would only change a part of my tokens, not the entire treasury, but don't consider this as advice either.
