Looks like the old Sui RPC must have had serious vulnerabilities, which is why they updated to GRPC and completely disabled the old one. OMG, I've been messing around on this problematic chain for so long, it's honestly terrifying Right now, OKX and Onekey still haven't upgraded to GRPC. Not sure if they're worried about risks with the new one. For staked assets, you can only switch wallets to slush. Just a heads-up for everyone
