Security firm CertiK said in a recent email announcement that in the last 24 hours, “suspicious” transactions worth over $3 million were sent out of the Bitcoin Lightning-based exchange FixedFloat. According to CertiK, funds were moved in ether (ETH) and tether (USDT) to wallets on the Ethereum and Tron networks, respectively. The behaviour was called a “exploit” by CertiK in the email.
“Around $2 million of the funds were placed in eXch, exhibiting conduct akin to the FixedFloat occurrence on February 16th, while an additional $100,000 USDT was transferred to a Binance wallet on Tron,” the company stated.
Tuesday afternoon early European hours see FixedFloat’s website unavailable due to “technical work.” Regarding the withdrawals, social media accounts have not responded, and FixedFloat’s most recent post on X was made on March 31.
FixedFloat is a completely automated cryptocurrency and token exchange service built on top of Bitcoin Lightning, a network that uses micropayment channels to facilitate quicker and less expensive transactions on top of the main Bitcoin blockchain.
A FixedFloat support agent verified that there had been a technical issue with the exchange. Regarding the questionable transfer activities, they remained silent.
“We moved our service to the technical work mode due to a few minor technical issues. The support team stated via a live chat that the recovery time was yet undetermined.
