Overview

Tholos is a non-custodial treasury management platform that uses multi-party computation (MPC) to secure digital assets. Your organization retains full control of its keys — Tholos never has access to your funds.

The Tholos API lets you programmatically manage organizations, vaults, transactions, and policies. Use it to build custom integrations, automate treasury operations, or embed Tholos functionality into your own applications.
