Solana Foundation names ex-Twitter security chief Michael Coates CISO

Michael Coates has joined the Solana Foundation as its new Chief Information Security Officer, bringing a track record from Mozilla, Twitter, and his own security startup. He announced the appointment on X, saying he will lead security efforts across the network as blockchain adoption and institutional activity pick up.

Coates pointed to Solana’s scale as a big reason for joining. He noted that the network now handles tens of billions of dollars in daily stablecoin volume and processes more transactions each day than most of the crypto industry combined. He also highlighted recent tokenization moves on Solana, like the launch of SpaceX tokenized shares on the same day the asset debuted on Nasdaq.

From Mozilla to Twitter to crypto

Coates previously served as Head of Security at Mozilla during the browser wars era. He later became Twitter’s first CISO as the platform expanded globally. After that, he founded Altitude Networks, an enterprise SaaS security firm that got acquired by CoinList and entered the crypto space. His background gives him a broad view of security challenges at scale.

At the Solana Foundation, Coates plans to strengthen operational security, improve application security practices, and address risks that are unique to digital assets. He also said he intends to work with policymakers and standards bodies on cybersecurity regulation affecting the crypto industry. It’s a role that combines technical oversight with some policy work, which seems fitting given his past experience.

Threats and AI concerns

Coates described the current threat landscape as intense. Attackers remain heavily motivated to steal digital assets, he said, and malicious uses of artificial intelligence are becoming an increasing concern. But he also sees potential upside — AI can strengthen defensive capabilities when used the right way. He referenced his congressional testimony on this topic earlier this year, so it’s clearly something he’s been thinking about for a while.

The appointment is part of a broader trend where digital asset firms hire seasoned leaders from tech, cybersecurity, and regulatory backgrounds. Institutional participation is expanding, and companies want people who have dealt with high-stakes security before. A similar move happened last year when former U.S. Commodity Futures Trading Commission Chairman Christopher Giancarlo joined Swiss digital asset bank Sygnum as a senior policy advisor. At the time, Sygnum said Giancarlo would advise on global regulation and strategic partnerships. That pattern — bringing in experienced executives — seems to be accelerating as the crypto infrastructure matures.
