L-BTC is trading again. The bitcoin behind it is only 85%.
SideSwap reopened Liquid markets while federation peg-outs stay off and public reserves cover roughly 85% of outstanding L-BTC.
News analysis
Liquid Bitcoin is back on order books. That does not mean every L-BTC still maps to a redeemable bitcoin.
Markets reopened. The exit to Bitcoin did not.
SideSwap said on September 10 that the Liquid Network was producing blocks again and that its swaps and markets were open as they were before the September 6 pause. An update dated September 11 added that peg-in through SideSwap was open again. Peg-out, SideSwap said, stays closed.
That split is the whole story in miniature. Holders can trade L-BTC against other Liquid assets on an open book. They cannot, through the Federation route SideSwap describes, burn L-BTC and take BTC off the Bitcoin network while peg-outs remain blocked by bridge nodes during the Federation’s security review.
Blockstream’s own staged restart language, as summarized in contemporaneous coverage, put block production back first and kept peg operations, including PAK-authorized peg-outs, suspended while reserve restoration continued. Trading answers “what will a counterparty pay?” Redemption answers “can I leave with bitcoin at par?” Those are different questions.
Public reserve readings sit near 85%, not 100%
SideSwap’s September 10 note cited liquid.network figures for that day: 4,205 L-BTC in circulation against 3,597 BTC in the Federation reserve. Of roughly 3,996 BTC pegged out on September 6, SideSwap said 3,400 BTC was returned to the Federation on September 7 and is included in that reserve figure.
CryptoSlate later published a separate onchain snapshot timed 22:55 UTC on September 10: about 4,229 L-BTC outstanding against about 3,601 BTC in the cited reserve addresses. Derived coverage there was about 85.15%, with a gap near 628 BTC. Across the SideSwap citation and the later API pair, coverage stays near 85% while the absolute counts drift slightly. Treat each row as a time-stamped reading, not a final loss certificate.
The arithmetic matters because Liquid’s design treats one L-BTC as a claim backed by one BTC held by the federation. When outstanding claims exceed visible reserve bitcoin, and when the authorized peg-out path is off, a market print near “1.00” is a confidence story, not an arbitrage lock. Suspended peg-outs remove the classic redeem-the-discount loop that used to enforce parity.
SideSwap attributed a September 10 public statement by Blockstream CEO Adam Back: the L-BTC to BTC peg will be covered one to one, and peg-in and peg-out will resume in a later step after further system updates. SideSwap welcomed the statement and said how and when restoration happens is for Blockstream and the Federation to announce.
That is the cleanest framing available in the public record we opened: a named executive commitment to eventual 1:1 coverage, paired with an explicit deferral of the operational peg. It is not the same thing as an open redemption window today. Blockstream’s status language, as reported, described restoration as in progress without naming a capital source or a deadline in the materials reviewed for this piece.

Why a traded price can mislead holders
SideSwap was explicit that it does not set or hard-peg the price of L-BTC. Its markets are open order books. In the first hours after reopening, it expected thin books and large moves, and it advised limit orders over market takes.
That honesty cuts both ways. An open price is better than a dark market. It is also easy to misread. A small clip clearing near par can coexist with a large overhang of claims and no Federation exit. Other Liquid assets, including USDt and DePix as SideSwap described them, depend on their own issuers’ backing, not on the L-BTC reserve. Their ability to trade does not certify the bitcoin peg.
The September 6 incident, per SideSwap’s earlier statement, involved a consensus bug in Elements that allowed creation of roughly 4,000 L-BTC without a matching deposit, then a standard peg-out path that released about 3,996 BTC. SideSwap said Blockstream stated that no SideSwap key was compromised. The network-level response, the security review, and the reserve gap are downstream of that event. Reopening the books without reopening peg-outs is a deliberate intermediate state, not a full restore.
What to watch before calling L-BTC “fixed”
Three dated signals still matter more than any single tick:
1. A Federation or Blockstream notice that peg-outs have resumed, with any queues, caps, or staged access spelled out.
2. Reserve accounting that shows outstanding L-BTC and BTC in reserve converging toward the 1:1 claim SideSwap attributed to Adam Back.
3. Confirmation from the specific peg provider a holder uses (SideSwap promised to explain changes to its own peg service before reopening it).
Until those land, L-BTC’s market is a price discovery venue under incomplete redemption. Trading again is real. Eighty-five percent public coverage, while peg-outs stay suspended, is also real. Confusing the two is how holders get hurt.
