Blockchain security company CertiK said September has become the worst month for cryptocurrency exploits so far in 2023, with losses exceeding $329 million. The largest contributor came from the Mixin Network attack on September 23, which caused losses of US$200 million. On the other hand, DeFi lending protocol Yield announced that it will permanently shut down in December due to lack of business demand and global regulatory pressure.

Polygon co-founder Jaynti Kanani announced her resignation from day-to-day work at the company, saying she would monitor from the sidelines. Meanwhile, Nature Science magazine said decentralized autonomous organizations (DAOs) could help scientists find funding and community. In addition, crypto payment service provider Wirex launched W-Pay, a non-custodial crypto debit card service based on zero-knowledge proofs, aiming to improve scalability and security.

The DeFi market has had a mixed week, with most of the top 100 coins trading in the same price range as last week. The total value locked in DeFi protocols fell to $45.07 billion.
