Stendar SDK

Stendar is a programmable financial-agent SDK and safe runtime. It helps teams design runtime workflows, gate money-affecting actions behind policies, and keep auditable receipts attached to each decision.

Start by audience

Agent Builders: integrate SDK surfaces, AI adapters, and custom workflow logic in Agent Builders.
Operators: apply trust controls, approvals, audit verification, and live execution gates.
End Users: delegate tasks, review plans, approve or reject actions, and inspect receipts.
