Paxos, the digital asset infrastructure firm, has integrated AI coding agents called Hoplites into its Slack-based engineering workflow. The agents now handle 15% of the company's pull requests, and Paxos says the move has cut cycle times sharply.
The Hoplites Workflow in Slack
Hoplites operate directly inside Slack, the chat tool Paxos engineers already use every day. Rather than a separate dashboard or command-line tool, the agents sit where the team already discusses code. They pick up engineering tasks, help review changes, and produce pull requests automatically.
According to Paxos, the agents aren't just assisting with mundane chores. They're enhancing the internal tools the engineering team relies on daily. That could mean patching small bugs, updating configurations, or adding tests — the kind of work that traditionally eats up hours of a developer's day.
What 15% Automation Actually Looks Like
Pull requests are how code gets reviewed and merged. Automating one in seven of those requests means engineers spend less time on repetitive tasks and more time on the harder problems that still need human judgment. Paxos didn't say exactly which kinds of PRs the agents handle, but the company did note that the automation has significantly cut cycle times — the time it takes from writing code to getting it merged.
The 15% figure also gives a sense of scale. That's not a toy project or a pilot. It's enough to change the rhythm of a development team.
Why Cycle Times Matter
In software, cycle time directly affects how fast a company can ship fixes and features. For Paxos, which runs regulated financial infrastructure, speed has to be balanced against correctness. Hoplites seems to be handling the low-risk, high-repetition work, freeing human engineers to focus on the parts that need careful thought.
Paxos hasn't described how the agents are trained or which models run them. It's also not clear whether the 15% will grow. The company framed the deployment as an enhancement to internal tooling, not as a replacement for its engineering staff.
For now, the agents are a tool, not a team.
How Paxos Uses AI Without Displacing Engineers
This isn't about layoffs or headcount reductions. The automation is designed to make the existing engineers faster. Paxos has a regulated business — it's a qualified custodian and a digital asset services company — and its technology has to be reliable. Hoplites reduces the drudge work, letting engineers concentrate on the parts of the system that still need a human's eye.
What's unclear is how much further Paxos plans to take this. The company didn't announce a roadmap or a target for the automation rate. The integration with Slack suggests the agents are built into the company's daily routines rather than experimental, but it's still an early story.
Developers at Paxos will likely see the percentage of automated pull requests climb slowly. The next thing to watch is whether other fintech companies follow suit — and whether Paxos expands Hoplites to other parts of its engineering pipeline.
