Liquid Network, the Bitcoin sidechain launched in 2018 to speed up exchange settlements, announced that a security exploit has wiped out almost its entire reserve – about 4,000 of the 4,200 bitcoin stored in its federation wallet, equivalent to $320 million at today’s price. The breach forced the network to halt all new transactions while federation members scramble to fix the vulnerability.

Blockstream, the infrastructure provider behind Liquid, traced the loss to a software bug in its Elements protocol rather than a compromised private key. The stolen coins were moved through SideSwap, an approved trading platform, which treated the tainted and legitimate coins indistinguishably. The hacker, presenting themselves as a “white‑hat,” is now communicating on‑chain, demanding that the bug be patched before any return.

DATA & FIGURES

$320 million exploit; 4,200 BTC total reserve; 4,000 BTC withdrawn; 80+ federation members; $79,520.34 per BTC; Bitcoin down 0.55 %; ETH down 0.26 %; XRP down 0.88 %; SOL down 1.47 %; article updated 2 hrs ago; published 8 hrs ago.

THE SCENARIO

Liquid was built to address Bitcoin’s slow confirmation times by issuing L‑BTC against locked bitcoin, allowing instant settlement for exchanges. The near‑total drain of its reserve raises serious doubts about the security of sidechain models that rely on a federated custody structure, especially as the crypto industry battles a wave of high‑profile breaches this year.

DIRECT QUOTE

"Liquid wallets will be impacted, and we’re sorry for any inconvenience," Liquid Network said on X.

BBN INSIGHT

BBN Insight:
The Positive Side – The hacker’s willingness to return the funds after a fix could pressure Blockstream to accelerate bug remediation and implement stricter node verification, ultimately hardening the network for all participants.
The Negative Side – The incident shatters confidence in federated settlement layers, may push exchanges to revert to on‑chain Bitcoin trades, and could trigger regulatory scrutiny over the safety of off‑chain liquidity solutions.

MARKET REACTION

Following the news, Bitcoin slipped 0.55 % to $79,520.34, Ethereum fell 0.26 % to $2,493.93, XRP dropped 0.88 % to $1.41, and Solana declined 1.47 % to $105.26 as investors reassessed risk across crypto assets.
