The Sandbox Contained Bridge Exploit Minting Unbacked SAND

The freeze by Upbit and Bithumb, not the exploit itself, is the sharper signal: Korean exchanges acted under local rules before the studio's own containment could be independently verified, and the halt lands on Ethereum, which The Sandbox says was unaffected. That mismatch — a chain untouched by the incident still losing transfer functionality — shows how quickly compliance reflexes can outrun technical facts, and how exchange-level access, rather than the bridge, becomes the binding constraint. Whether the Ethereum halt is lifted on the studio's assurances, or whether other venues follow, is the open question.
