Coinbase Global (COIN) has agreed to make a strategic investment in Singapore-headquartered cryptocurrency exchange Zipmex, according to a report by The Block.
- Zipmex reportedly has plans to raise $40 million in a Series B+, pushing its valuation to $400 million. Last year, the firm raised $41 million in a Series B with investment from the Bank of Ayudhya, one of Thailand's largest banks.
- The exchange is headquartered in Singapore and has offices in Thailand, Indonesia and Australia. Coinbase was previously in acquisition talks with Zipmex, although it opted against that in March, according to the report.
- Coinbase shares were up 1.45% at $70.55 in pre-market trading. But by mid-morning, they had fallen 4.8% to $65.80.
- Coinbase and Zipmex did not immediately respond to CoinDesk's request for a comment.

Specialized AI detects 92% of real-world DeFi exploits

New research claims specialized AI dramatically outperforms general-purpose models at detecting exploited DeFi vulnerabilities.
What to know:
- A purpose-built AI security agent detected vulnerabilities in 92% of 90 exploited DeFi contracts ($96.8 million in exploit value), compared with 34% and $7.5 million for a baseline GPT-5.1-based coding agent running on the same underlying model.
- The gap came from domain-specific security methodology layered on top of the model, not differences in core AI capability, according to the report.
- The findings come as prior research from Anthropic and OpenAI shows AI agents can execute end-to-end smart contract exploits at low cost, accelerating concerns that offensive AI capabilities are scaling faster than defensive adoption.
