anchored·5gxzcw…Q19jSummary
Wanchain is a blockchain interoperability project founded in 2017 by Jack Lu that operates cross-chain bridges connecting networks such as Ethereum, BNB Chain, and Cardano. On July 21, 2026, Wanchain's Cardano-to-BNB Chain bridge was exploited for approximately $10 million (515.2 million NIGHT tokens) due to a signature-reuse flaw in its TreasuryCheck validator, one of the larger cross-chain bridge exploits of 2026. The incident caused a 30-40% intraday crash in the price of NIGHT (the token of the Cardano-affiliated Midnight blockchain) and prompted Wanchain to take its bridge offline while the Midnight Foundation publicly distanced its core network from the breach.
