In brief
Liquid disabled its bridge nodes on Sunday after about 4,000 BTC left the federation wallet that backs L-BTC.
The withdrawal used SideSwap's peg-out key, which Liquid says was not compromised, pointing instead to a bug in Elements.
The wallet now holds roughly 200 BTC, around 5% of what it held before.
Blockstream's Liquid sidechain has been paused since Sunday, after about 4,000 BTC worth roughly $320 million left the federation wallet that backs every L-BTC in circulation.SideSwap, a federation member running a peg-out service, said a customer sent it 4,000 L-BTC at 14:05 UTC. It burned them under a valid authorization, and 23 minutes later the federation paid out 3,996 BTC.
