A self-described white-hat party returned 3,400 BTC to Liquid Network’s federation wallet on Monday after Blockstream said bridge nodes were patched. About 598.5 BTC, near $47 million, remains at the holder address.
Liquid Network said purported white-hat hackers withdrew about 4,000 bitcoin from the federation wallet that backs L-BTC. Bridge nodes are disabled and the sidechain is paused.
