How Custena works
Two sides.
One ledger.
Every call governed.
Enterprise teams govern every dollar their agents spend - with per-agent budgets, real-time approvals, and EU AI Act Article 26 audit evidence. MCP servers and APIs earn from every agent call, on every protocol, without code changes.
Connect, govern, approve, audit - the four moments every agent payment passes through.
For agentic buyers
Govern every dollar your agents spend.
Deploy spending AI agents safely. Real-time policy enforcement, human approvals, and EU AI Act Article 26 audit evidence built in from day one.
Top up your balance
Add funds via card, SEPA, bank transfer, or USDC. No crypto wallet required. Agents draw from a shared Platform Balance - one top-up covers all protocols.

Real-time spending controls
Every request hits the policy gate. Per-agent budgets, vendor allow-lists, category limits, and duplicate detection evaluated in milliseconds.
Human approvals where they matter
Spends above a threshold pause for a human decision. One click approves or denies in Slack, the dashboard, or the API. The agent waits for the answer.

Audit trail and Article 26 evidence
Every decision writes a span with the reasoning attached: agent identity, endpoint, amount, approver, and policy. Cryptographically logged and exportable for a regulator audit. Enforcement begins August 2, 2026.
