## Key takeaways

Moonwell, a decentralized lending protocol, is currently investigating a significant issue on its lending market deployed on the Base network. Security firms CertiK and PeckShield have flagged the incident, estimating losses of around $8.7 million. The exploit appears to involve the manipulation of the collateral price of MAMO, a token associated with the Base network.

This incident also serves as a reminder to diversify investments and not to rely solely on a single platform or token.

## What to Do Next

For those affected or concerned, the next steps involve closely following Moonwell's official communications. The protocol is likely to provide updates on the investigation and any potential compensations or measures to mitigate the impact. Users should also consider reviewing their own security practices and ensuring they are using reputable platforms with robust security measures in place.
