In an X post, blockchain sleuth “Spreek” said he was “fairly sure this is NOT an approval-related issue and is only related to the TVL held in the Kyber pools themselves.”
The attacker has also left an on-chain message for protocol developers and DAO members, saying “negotiations will start in a few hours when I am fully rested.”

DefiLlama data shows KyberSwap’s total value locked (TVL) tanked by 68% over a few hours and almost $78 million left the protocol due to the hack and user withdrawals. Its TVL currently stands at $27 million, down from its 2023 peak of $134 million.
Kyber Network Crystal KNC token prices briefly dipped 7% as news of the exploit broke but have since recovered to trade at $0.74.
The team identified a vulnerability in April, advising users to withdraw liquidity. However, no funds were lost in that incident.
