Despite navigating regulatory controversies, he remains influential in the crypto industry, particularly active in innovating perpetual swaps and sharing market perspectives.Overall, Arthur Hayes is still regarded as a key opinion leader in the crypto market, with his asset structure closely correlated to market cycles.

Taiko bridge attack may result in losses up to $1.7 million
Ethereum Layer 2 blockchain Taiko has stated its chain state verification mechanism has been compromised, and the security assumptions of all bridges deployed on Taiko can no longer be relied upon. It urges users to immediately withdraw funds from the relevant bridges. Taiko says it is coordinating with partners to control the incident and has suspended the affected systems.Crypto security firm Blockaid stated that the root cause appears to be a flaw in the way Taiko's bridge validates source signals. Attackers can submit message proofs on Ethereum that lack legitimate proof from the Taiko chain, thereby registering and withdrawing fraudulent bridge messages. This leads to the unauthorized release of assets from the ERC20 treasury. Blockaid estimates at least $1 million was stolen, while Lookonchain and PeckShield believe the value of stolen assets could be as high as $1.7 million.PeckShield reported that the attacker has transferred approximately 1.99 million TAIKO tokens to MEXC, valued at around $189,000.
