PANews reported on May 23 that according to Protos, the cross-chain DeFi project Chainge was exposed to have trapped user funds for months, and the promised solution failed to deliver. The project is led by Multichain founder DJ Qian and has both cross-chain bridge and decentralized exchange functions. User complaints show that from the end of 2024 to the beginning of 2025, a large number of users reported that transactions were stuck and could not be processed, especially wKAS (packaged version of Kaspa) cross-chain problems. The team blamed "malicious actors abusing the service to cause liquidity shortages", but wKAS has now been significantly decoupled and its partnership with "kas.fyi" has been terminated.

The project owner announced on March 24 that the issue would be "100% resolved", but it has not been fulfilled as of May 22. The front-end page still has cross-chain functions, which poses a risk of continued capital absorption. Protos has contacted the Chainge team for comment, but has not received a response.
