Canadian digital asset platform Bull Bitcoin estimates that liquid bitcoin (L-BTC) withdrawals could resume within 30 days, following a major exploit that drained roughly 4,000 BTC from the Liquid Network on September 6, 2026. According to updates published by Bull Bitcoin, the suspension remains necessary because the Liquid Federation has not yet restored the full 1:1 backing of the network’s circulating assets, leaving outbound peg-out mechanisms offline.
The Liquid Network Exploit and Reserve Deficit
The security incident began on September 6, 2026, when a vulnerability in the Elements software allowed unauthorized actors to mint approximately 4,000 L-BTC without adequate collateral. Before the breach, the reserve held about 4,200 BTC, but it plummeted to roughly 197 BTC immediately following the exploit.
Subsequent negotiations led to a partial return of funds. On September 7, 2026, the attackers returned approximately 3,400 BTC, leaving roughly 598.50 BTC unrecovered, an amount valued at a significant sum according to Diario Bitcoin. Data published by the exchange SideSwap on September 10, 2026, indicated that the Federation held 3,597 BTC in reserve against 4,205 L-BTC still in circulation. That left an uncovered deficit of roughly 608 BTC that must be resolved to re-establish a secure 1:1 backing ratio.
Operational Impact on Bull Bitcoin and Lightning Payments
While the Liquid Network managed to resume block production and internal L-BTC transfers on September 10, 2026, outbound peg-outs to the main Bitcoin blockchain remain frozen. Bull Bitcoin stated that its conversion services from L-BTC to BTC depend entirely on those network-level exits. Without active peg-outs, accepting incoming L-BTC would force the platform to accumulate an asset it cannot reliably convert back into standard bitcoin, creating an unmanageable liquidity risk.
To mitigate this exposure, Bull Bitcoin chose to keep incoming Lightning Network payment channels disabled rather than shift the risk onto its customers. The company clarified that its projected 30-day timeline for the return of L-BTC swaps is an operational estimate rather than a guaranteed date from the Liquid Federation. Blockstream and the Federation continue to demand the return of the remaining 598.50 BTC while conducting comprehensive security reviews of their infrastructure.
Next Steps for Platform Architecture
The prolonged outage has prompted wallet providers and exchanges operating on the Liquid sidechain to re-evaluate their dependency on federated architectures. Bull Bitcoin reported that it is actively reviewing its payment infrastructure to reduce reliance on mechanisms tied to single-federation exit points. As the Liquid Federation works to clear the reserve deficit and finalize security audits, the timeline for restoring full peg-out functionality remains dependent on both the recovery of the remaining funds and the formal reactivation of network-level exit channels.
