More than 95 percent of code written at Coinbase is being generated by artificial intelligence or created with AI assistance. The company is expanding AI as a core tool across development and operations and is reshaping how it runs the organisation around AI.

Cointelegraph, a blockchain outlet, reported on Monday that Rob Witoff (롭 위토프), head of the Coinbase platform, said "95 to 100 percent" of code is currently written using AI. That marks a sharp increase in usage in just a few months compared with the roughly 40 percent share the company presented in February.

AI is spreading quickly beyond development teams to the whole company. Witoff said nearly all employees currently use AI every day.

Coinbase CEO Brian Armstrong (브라이언 암스트롱) also said in an email sent to employees in May that AI is "dramatically changing" the speed of work. He stressed the company must put AI at the centre and regain the pace and focus of its early days. Coinbase cut about 700 jobs in the same month.

AI is not doing all development work. Witoff said the level of AI use varies widely depending on the nature of the project. Code related to core cryptography still has a high share of human review and writing, but internal prototype development is effectively handled 100 percent by AI. Core service development sits between those two areas, he added.

AI use is also expanding in code verification. Coinbase is using AI to check whether code operates normally, identify security vulnerabilities and conduct mathematical verification. Still, people continue to account for a significant share of direct review at this stage, the report said.

The spread of AI is also changing the structure of development staffing. Witoff said 2 to 3 engineers can now handle work that previously required more than 10 people. He said junior developers were particularly affected during the recent restructuring, while adding that job cuts were carried out across the company, including marketing, legal, customer support and compliance, as well as development teams.

Engineers' work methods have also changed significantly. Coinbase developers are currently using 5 to 10 AI agents at the same time, and the company assessed that the volume of coding work they perform is equivalent to about 1,200 developers.

Witoff said AI use is expected to expand further. He said that by 2030, AI agents could handle work performed by a workforce of up to 100,000 people.

AI usage has surged, but costs have not risen as much as expected. Armstrong said AI token usage has increased sharply, but related costs have remained at nearly unchanged levels.

The trend is not limited to Coinbase. In the cryptocurrency industry, productivity gains driven by AI are being accompanied by slimmer organisations. Crypto.com cut about 12 percent of its staff this year, and Block CEO Jack Dorsey also stressed AI-driven operations while reducing the workforce by about 40 percent.

Other major cryptocurrency companies, including Kraken, Gemini, Messari and Dune, are also pushing efficiency measures and organisational restructuring using AI.

Coinbase's case shows AI is going beyond a simple coding assistant to change software development methods and organisational structures. The company still maintains that human judgement remains essential in areas such as core security and cryptography and strategic decision-making.
