A vulnerability in Multichain systems has led to the theft of at least $3 million, reports suggest.
Multichain, previously known as Anyswap, is a cross-blockchain router protocol designed to allow users to swap and exchange digital tokens across chains while reducing fees and streamlining the overall process.
However, chaos now reigns in the ecosystem due to a cybersecurity incident caused by a vulnerability in the network, as first reported by Vice.
Dedaub reported the vulnerability to Multichain. The company said in a blog post dated January 17 that the critical flaw impacted WETH, PERI, OMT, WBNB, MATIC, and AVAX swaps, but assured users at the time that “all assets on both V2 Bridge and V3 Router are safe [and] all cross-chain transactions can be done safely as usual.”
