MPC wallet,
key management
& policy engine
- Keys never in one place
- MPC + TEE
- Policy-governed
- Tamper-resistant audit
- Segregated by design
The only architecture combining true threshold MPC, a configurable policy engine, and full deployment flexibility, with no third-party key access. Security is the design, not a feature bolted on top.
Your keys never exist
in one place
Private keys are the most sensitive component of digital assets. Tria FinTech protects them through multiple independent layers, supported across every deployment model.
MPC cryptography
True threshold MPC — a T-of-N signature scheme where each private key is split into shares distributed across client devices and TEE-secured servers. The key is never assembled in full at any single point, eliminating the risk of theft even in the event of a breach.
TEE technology
A Trusted Execution Environment provides hardware-level isolation for key operations. Even if the surrounding server infrastructure is compromised, operations inside the TEE remain protected and key shares cannot be extracted.
Your sole control
Private keys are generated and stored within your own perimeter. The infrastructure never has unilateral access to keys, or the ability to sign transactions without your authorisation.
Multi-party computation wallet architecture is supported across all deployment models, in-house, cloud and hybrid, with the same security guarantees at every level.
A policy engine that governs
every fund movement
Structural governance is enforced before any key share activates. A multi-user wallet only delivers security if the approval process is strictly enforced, so every stage is mandatory.
-
Policy setup
Admins configure rules, limits, and quorums.
-
Initiation
An authorised user creates the request, never the approver.
-
Validation
Auto-checked against policy rules; violations rejected.
-
Approval
Routed to designated approvers by policy quorum.
-
Signing
MPC key shares sign across devices and TEE servers.
-
Execution
Submitted to the blockchain.
Complete visibility across every wallet and operation
Audit-ready architecture with deep operational visibility, built for regulated environments.
Comprehensive audit trail
Every operation captures initiator, approvers, timestamps, and device identifiers.
End-to-end monitoring
Full visibility across all wallets for compliance and finance teams.
Cryptographic integrity
Tamper-resistant databases ensure audit logs cannot be altered retroactively.
Complete attribution
Nothing is anonymous. Every decision is tracked to a specific user and device.
Same security architecture,
deployed your way
The MPC key management and policy engine operate identically in every configuration. What changes is how much of the stack you run, and how much control stays inside your perimeter.
Cloud
ManagedFully hosted custody platform. We run the infrastructure; you keep full policy control.
Hybrid
Shared controlA self-hosted signer with shared operations. You hold a key and co-sign every movement.
In-house
Full controlEvery key and every operation stays inside your perimeter, with zero external dependencies.
