The Liquid Network has yet to reopen the L-BTC to Bitcoin peg-out gateway, even though the network resumed block production and transactions on September 10. According to a Crypto Briefing report on October 11, the reserve remains short of around 603 BTC, and asset redemptions will only resume once full backing and security review conditions are met.
This is an update on the lingering aftermath of the September 6 incident, not a new exploit. For L-BTC holders, the ability to transfer tokens within Liquid and the ability to redeem BTC on the Bitcoin network remain two different things.
Flaw in minting unbacked L-BTC led to real BTC withdrawals
Liquid is a sidechain to Bitcoin. Users lock BTC into a reserve fund co-managed by a federation of members, receiving L-BTC redeemable at a 1 L-BTC to 1 BTC ratio. Converting in reverse is known as a peg-out.
In a September 9 announcement, SideSwap stated that a consensus bug in the Elements software allowed an entity to mint around 4,000 unbacked L-BTC. These tokens were transferred to SideSwap’s peg-out service, processed like normal customer orders, and the federation subsequently disbursed roughly 3,996 BTC.
According to SideSwap, none of the company’s keys, wallets, or systems were compromised. However, the entity acknowledged two operational oversights: keys authorizing peg-outs were kept online and funds were automatically forwarded to clients; the process also lacked limits on size, velocity, and screening of the sending wallet’s history.
SideSwap said an order accounting for a large portion of all existing L-BTC, originating from a wallet created just hours earlier, passed through without human review. This account from the party directly handling transaction processing indicates that software bugs and a lack of operational controls combined in the same incident.
Recovering most assets has not yet restored full backing
STOKR’s September 8 update noted that 3,400 BTC was returned on September 7, leaving approximately 598.5 BTC unrecovered. The October 11 report by Crypto Briefing placed the unreturned portion between 598 and 603 BTC, citing roughly 603 BTC for the current shortfall.
These figures were recorded at different points in time. Minor discrepancies between them should not be construed as an additional loss of funds. Crypto Briefing also cited a backing level of around 86% in mid-September; that is not a new independent measurement from October 12.
STOKR confirmed that the network resumed operations on September 10 after nodes were updated. Transfers and settlements of digital securities supported by the platform were restored, while BTC/L-BTC peg-out operations remained suspended. Thus, the L-BTC reserve incident does not imply that all assets issued on Liquid lost the same type of backing.
Reopening withdrawals depends on both assets and security procedures
According to Crypto Briefing, Liquid has set the restoration of full backing, software upgrades, and the completion of security audits as conditions prior to reopening peg-outs. In its own announcement, SideSwap also committed not to resume redemption services until both the company and the federation are confident that the process is secure.
Crypto Briefing quoted Blockstream CEO Adam Back saying that 1:1 backing would ultimately be fully made whole, but gave no specific date for reopening BTC peg-outs. That commitment does not yet serve as proof that the shortfall has been resolved.
For L-BTC holders, the key thing to monitor extends beyond announcements of normal network operations. When will the reserve be proven whole, and when will the new withdrawal controls be made public? Those two answers will determine the gap between a transferable token and an asset redeemable for Bitcoin.
