Partial Recovery for Liquid Sidechain Following Multi-Million Dollar BTC Drain

Following a significant security breach that saw nearly 4,000 BTC drained from its reserves, Bitcoin’s Liquid sidechain has seen a partial recovery of funds. While 3,400 BTC has been returned to the federation wallet by self-described "white-hat" hackers, the network continues to face operational hurdles and a lack of clarity regarding user withdrawals.

The Return of Assets and the "White-Hat" Mystery

On September 7, the Liquid federation wallet received a transfer of 3,400 BTC, marking a significant step toward restoring the backing for L-BTC tokens. The return followed an on-chain message from the hackers, who questioned whether returning most of the funds was acceptable before moving approximately 598.5 BTC—valued at roughly $47 million—to their own address. While a patch for bridge nodes has reportedly been issued and verified via Blockstream’s security keys, it remains unconfirmed whether the retained Bitcoin constitutes an agreed-upon bounty or a permanent loss for the sidechain’s reserves.

Lingering Outages and the Path to Full Redemption

Despite the influx of returned assets, the Liquid network remains in a state of high alert, with Blockstream’s official status page continuing to list a "major outage" affecting public bridge nodes. For L-BTC holders, the primary concern has shifted from asset backing to operational access, as major services and exchanges like SideSwap have paused deposits and withdrawals until further notice. A full reconciliation of recoverable reserves and a confirmed restart of bridge services are the critical next steps required to ensure that holders can once again convert their L-BTC back to Bitcoin in full.
