Upbit Flags SAND, Halts Deposits/Withdrawals

This is a venue-level risk action, not a token-level failure: Upbit's caution tag and deposit/withdrawal halt follow a bridge vulnerability that The Sandbox itself has acknowledged and contained by pausing cross-chain transfers. The practical effect is that SAND holders on Upbit face restricted movement while the underlying issue sits in bridging infrastructure shared with Base and BSC, not in the token contract. The open question is how quickly cross-chain functionality is restored and whether other exchanges mirror Upbit's caution designation.
