LI.FI is a protocol that allows users to trade across various blockchains, venues and bridges. It suffered a bug with its swapping feature in 2022, resulting in a $600,000 loss, PeckShield described the recent bug as "basically the same."
Initially the amount was tallied at $8 million, but project officials now estimate the total damage from the hack to be about $11 million.
"A smart contract exploit earlier today has been contained and the affected smart contract facet disabled," according to a statement emailed by a spokesman for the project. "There is currently no further risk to users. The only wallets affected were set to infinite approvals, and represented only a very small number of users."
The statement went on: "We are engaging with appropriate law enforcement authorities and relevant third parties, including security teams from the industry, to trace funds. We will issue a more detailed post-mortem as soon as possible."
Crypto security firm Decurity said that the exploit involves the LI.FI bridge.
"The root cause is a possibility of an arbitrary call with user controlled data via `depositToGasZipERC20()` in GasZipFacet which was deployed 5 days ago," Decurity wrote on X.
A report by Immunefi in May revealed that $473 million worth of crypto was lost to hacks, exploits and rug pulls in the first half of 2024.
UPDATE (July 16, 13:48 UTC): Adds link to 2022 exploit that resulted in a $600,000 loss.
UPDATE (July 16, 19:41 UTC): Adds statement from spokesman including updating the size of the hack to $11 million from an earlier reported $8 million.

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
