Liquid Network Says LBTC Is Fully Bitcoin-Backed Again After Closing Exploit Shortfall
By Crypto Wire
November 3, 2026
The Liquid Federation says every LBTC is fully 1:1 bitcoin-backed again — closing the hole left after September’s Elements exploit that drained most of the sidechain’s federation reserve. English wraps from CoinDesk and The Block on Nov. 3 quote the federation’s Monday/Tuesday restore language: reserves are “fully restored, reestablishing 1:1 BTC backing for all LBTC,” after a final 250 BTC transfer into the federation wallet. That is a reserve-math chapter, not a claim that every redemption path is already back to pre-incident defaults.
Incident backdrop stays fixed. On Sept. 6, a bug in Liquid’s Elements software let an attacker mint about 4,000 unbacked LBTC and redeem them for real bitcoin. Blockstream’s contemporaneous incident math put the federation reserve collapsing from about 4,205 BTC to roughly 197 BTC. The attacker — who framed the move as white-hat — returned about 3,400 BTC the next day after bridge nodes were patched, leaving a shortfall near 600 BTC (coverage clusters around 598–602 BTC). That shortfall is what Monday’s refill sequence was meant to erase.
On-chain timing for the close sits on Nov. 2 UTC evening deposits into the published federation address, including a 300 BTC move and the final 250 BTC print that federation-board commentary described as closing the remaining gap. Side coverage also notes an earlier 50 BTC deposit on Oct. 28 and smaller SideSwap contributions that helped shrink the hole before the Monday finish. Liquid’s public dashboard is the verification surface the federation pointed operators to — check the live reserve figure rather than a secondary screenshot.
Who funded the refill is still the attribution fight. CoinDesk’s Nov. 3 markets wrap says the federation did not cleanly name the source of the roughly 600 BTC needed to close the gap. The Block’s same-day ecosystem piece reports Liquid Federation board member Samson Mow identifying Blockstream as the source when asked on X — “As stated many times, Blockstream.” This desk keeps both receipts on the board: the federation’s restore claim is primary; the funder line follows named board commentary, not an invented treasury disclosure.
What is still not a full reopen. Provider swaps between BTC and LBTC at 1:1 through venues such as SideSwap have been available since late October. Direct federation peg-outs — the federation’s own redemption route for holders with peg-out authorization keys — remain under what the federation called “enhanced operational controls,” with governance and safeguard detail promised “in the coming weeks.” A fully restored reserve meets a stated precondition for restarting controlled peg-outs; it does not by itself prove those peg-outs are already wide open without new dated guidance.
For NFT and crypto desks that touch bitcoin sidechain settlement or LBTC inventory, the practical read is backing restored on the IOU while federation exit rails stay gated. Treat any “early peg-out” pitch over direct message as a scam vector until the federation dates a controlled restart on its own channels. Elements hardening language from Blockstream’s Adam Back — refreshed peg-out keys in cold hardware, disabled proof-validation caches, fail-closed consensus rules, and third-party audits — is backdrop for why the bug class mattered, not a substitute for the reserve print itself.
Dollar labels around the September drain still cluster near about $320 million at then-prices for the ~4,000 BTC path; today’s refill chapter is about closing the residual ~600 BTC hole, not re-litigating the first-day return of 3,400 BTC. Prefer Liquid’s dated restore text, the public reserve dashboard, and named board/attribution quotes over aggregator copy that collapses “fully backed” into “fully reopened.”
What to watch on-chain next: a dated federation notice that lifts or schedules direct peg-outs under the enhanced-control restart, any fresh deposit or outflow on the published federation reserve address after the 250 BTC close, and governance notes that name keys, audits, or fail-closed rules beyond the restore tweet.
Bottom line: Liquid says LBTC is fully 1:1 bitcoin-backed again after the final reserve refill that closed the September shortfall — while direct federation peg-outs stay under enhanced controls.
