17, solo, no funding — building the financial OS for AI agents

I'm a full-time college student building Valta by myself, outside class hours. No co-founder, no funding, no team.

The problem I kept running into: agents are starting to have real spending power (metered LLM calls, trading APIs, tool purchases) but there's no layer that says "this agent can spend at most $X/day" and enforces it, and no audit trail that survives someone asking "prove what happened." Most teams find out an agent went rogue when the invoice arrives.

Valta gives every agent its own wallet: hard spend caps per transaction and per day, a SHA-256 hash-chained audit log (tamper-evident by construction), and a one-click kill switch. I also open-sourced the underlying patterns (spend gate + hash chain, an MCP server, and a free CLI called valta-leak that scans agent code for cost bugs like unbounded loops) rather than keeping everything closed.

It's free during beta, no credit card required. I'm mainly looking for people actually running agents with spend access to tell me what's missing or where this would break for their setup — happy to jump on a call with anyone building in this space. valta.co
