Sandbox Pauses Base and BNB Chain Bridging After SAND Exploit

The first sign of trouble in a token exploit is often not the exploit itself, but the freeze that follows. The Sandbox moved quickly on August 22 to disable bridging on Base and BNB Chain, isolating SAND tokens after an exploit across those networks.

The team also warned users not to trade SAND on Base and BNB, according to the original report. The immediate impact is small in supply terms, under 0.01% of SAND, but the operational response is larger than that number suggests.

Bridging creates multiple representations of the same asset, and each representation depends on the security of a separate bridge contract.

If one side is compromised, the safest move is to stop movement while the project determines whether the affected tokens can be isolated or returned.
