Overview
xes.software is a security firm that builds custody systems to protect the private keys behind digital assets. A private key is the secret that controls a wallet, and once it leaks there is no way to undo the damage, so the firm's whole job is keeping that key out of reach. It builds for organizations that hold crypto and cannot afford a single mistake, generating and using keys inside sealed hardware that no one, not even the firm or the client's own staff, can read directly1.
The firm works across the Bitcoin and Cardano ecosystems, and its named partners UTXOS and Mesh.js are both developer-tooling teams on Cardano1. Rather than selling one fixed product to everyone, it designs each system around the specific risks a given organization faces1.
Key Features
- Keys that stay sealed away. xes.software runs the sensitive work inside a trusted execution environment, a locked-off section of a server that keeps secrets isolated from everything around it. Your software asks it to sign a transaction; the key itself never leaves the box2.
- You keep your own assets. Systems are self-custodial, meaning the customer always holds their own funds. The firm hardens the software but never takes control of the assets3.
- Run it on your own servers. The custom option is self-hosted and comes with full ownership of the software and no ongoing subscription, so an organization can keep the whole setup in-house3.
- Built for real-world threats. Every engagement starts with a threat model, a written map of how an attacker might try to break in, so the design fits the organization's actual risks instead of a generic checklist1.
- Cardano and Bitcoin support. The TrustVault Premium product is built for the Bitcoin and Cardano ecosystems and lets clients pay their subscription in stablecoins, and custom builds can target other networks3.
What to Expect
xes.software is a business-to-business service, not a wallet you download. The website is built around two clear paths: explore the published solutions, or request a demo and talk to the team about a custom build. There is no sign-up flow or free tier; the firm describes its pricing as simple, with no metered billing or hidden costs.
The work itself is consultative. A project begins with a review of your organization's assets, team, and the rules you operate under, and the architecture is designed from there. The flagship product, TrustVault Premium, supports Bitcoin and Cardano and is self-custodial and extendable; the Custom Solution path hands over complete software ownership for teams that want to self-host3.
For a sense of how the firm thinks, its resources section publishes plain technical writing on key security, including a walkthrough of why storing private keys in ordinary server settings is risky and how isolated hardware closes that gap2. If you are weighing how to hold crypto safely, it is worth reading alongside Adastack's other privacy and security listings.
