cybersecurity Crypto Exchanges Seek AI Models Capable of Autonomous Smart Contract Hacking
Simulated damage worth millions of dollars resulted from AI agents using the Claude Mythos Preview model to autonomously hack smart contracts. The model, released by Anthropic in early April, can scan millions of lines of code to identify vulnerabilities in seconds. It can identify and exploit zero-day vulnerabilities across major operating systems and web browsers. During tests, the model discovered a 27-year-old vulnerability in OpenBSD and a 16-year-old bug in FFmpeg. Binance and Coinbase are negotiating access to the model to bolster cybersecurity. Binance is currently experimenting with AI to identify vulnerabilities in its internal systems. Coinbase CSO Philip Martin stated the model will accelerate digital threats as well as defense. Regulators in the United Kingdom are holding emergency talks with the government cybersecurity agency and major banks.
Eligible users can complete transactions via Apple Pay, purchasing crypto directly within the Mixin app using fiat currency. All identity verification and payment processing are handled by Coinbase, while Mixin does not store sensitive personal or payment data.

cryptocurrency Solana's $10.71B DEX volume surpasses Coinbase and Kraken, signaling shift to on-chain trading
Solana’s decentralized exchanges processed $10.71 billion in trading volume, exceeding the combined 24-hour volume of Coinbase and Kraken. This shift toward on-chain trading occurred amid rising cryptocurrency market volatility fueled by US-Iran geopolitical tensions. Traders appear to be favoring non-custodial platforms, suggesting a growing preference for decentralized infrastructure when traditional markets face uncertainty. The surge in DEX volume on Solana reflects not just increased activity but a structural move toward trustless trading environments. Network performance held under pressure, reinforcing confidence in Solana’s capacity to support high-intensity financial activity during global stress events.
This integration is part of a broader effort to reduce onboarding friction. Mixin utilizes MPC architecture and Signal Protocol messaging to allow users to send crypto as easily as a text message. The wallet supports over 40 blockchains and 10,000 assets, providing 100% gas fee rebates on transfers between imported wallets.

venture capital Kraken’s $13.3 Billion Valuation Reveals a 33% Markdown in Exchange Pricing
Kraken is now valued at $13.3 billion, a 33% markdown from the $20 billion valuation the exchange commanded during its November 2024 funding round. This figure was established by Deutsche Börse Group's $200 million investment in Payward Inc., Kraken's parent company. The transaction, which is expected to close in the second quarter of 2026 subject to regulatory approval, gives the Frankfurt-based stock exchange operator a 1.5% fully diluted ownership stake via a secondary market transaction. The investment cements a commercial partnership first announced in December 2025 to build a hybrid market infrastructure for traditional and tokenized assets. Kraken had originally planned a public listing for 2026, but the company has suspended those plans indefinitely, citing unfavorable market conditions.
