Coinbase shares (COIN) came under pressure immediately the market opened on Tuesday, as a wave of customer backlash followed an internal disclosure that non-technical employees at the exchange are now shipping production code.

The reaction tapped into raw memories of the company’s May 2025 data breach, with several account holders publicly threatening to move funds off the platform and pushing back against CEO Brian Armstrong’s drive to accelerate engineering output.

For many Coinbase customers, the news arrived with the weight of a story they had heard before.

In May 2025, the exchange disclosed a breach affecting 69,461 customers, equal to less than 1% of its monthly active users at the time.

Cybercriminals bribed overseas customer support contractors linked to outsourcing firm TaskUs to siphon data from internal support tools.

The exposed data included names, emails, phone numbers, home addresses, dates of birth, masked Social Security numbers, masked bank account numbers, government ID images, and account balances.

Passwords and private keys were never compromised, yet the leaked information seeded phishing campaigns and social engineering attacks against affected users.

“…I don’t want to hear about what Coinbase is doing to recover funds – I want to hear what they are doing to better deal with private data. And why a $60B company, had such rubbish data policies when they can easily afford to hire top class talent?” Adam Cochran, a renowned X (Twitter) figure, said at the time.

Coinbase refused a $20 million ransom demand, publicly disclosed the incident, and pledged a matching bounty for information leading to arrests.

The company later estimated remediation costs could reach up to $400 million and faced multiple class-action lawsuits.

The acknowledgment that non-technical staff at Coinbase are now shipping production code reignited those memories almost immediately.

“AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated,” Armstrong said in the layoff announcement.

Account holders flooded social media with grievances tying the operational shift back to unresolved security anxieties.

“I think it goes without saying… Not your keys, not your coins. But the whole “non-technical teams are shipping production code” is…. kind of scary. I don’t keep a lot on CB as it’s only an on/off ramp for me, but this email just further cements that conviction,” one user stated.

Other account holders went further, citing personal harm tied to the 2025 incident. One user said home address exposure had triggered weekly harassment from social engineering scammers.

The pattern of complaints carried a common thread. Retail customers no longer trust the exchange as a custodian when its development pipeline now includes employees they assume lack formal engineering training.

>Non technical teams are now shipping production code

genuinely terrifying lol, already had my data leaked enough before this

Against this backdrop, Coinbase stock, COIN, fell by almost 5% after markets opened on Tuesday, and was trading for $196.21 as of this writing.

Coinbase CEO Brian Armstrong addressed the criticism directly on X (Twitter), denying that the company allows untested code into live systems.

It goes without saying that all AI generated code has rigorous human reviews. No one is vibe coding directly to production. We're increasing speed of shipping and innovation, while continuing to raise the bar on security.

His response reframed the policy as a productivity push rather than a quality concession. Whether that distinction reassures retail holders who already feel exposed by the 2025 breach is a separate question, and one the market appears to be answering through pressure on the COIN ticker.

The friction reflects a deeper standoff over how much trust an exchange should expect from users who have already paid the cost of a prior security failure.
