# Tresori MPC

#### What Tresori MPC Is

Tresori MPC is a secure, enterprise-grade wallet security model built on Multi-Party Computation (MPC) and Threshold Signature Schemes (TSS).\
It allows applications to sign blockchain transactions without ever creating, storing, or exposing a complete private key, not on the server, not on the client, not anywhere.

Instead of *one private key*, Tresori distributes **key shares** across multiple independent parties. A transaction is signed **collaboratively**, and only the final signature is produced, never the key itself.

> Think of it like a nuclear launch system:\
> no single person has the full code, yet actions can still be authorized safely.

#### Why Tresori Uses MPC

| Traditional Model  | Risk                        |
| ------------------ | --------------------------- |
| Single private key | Total loss if compromised   |
| Seed phrases       | User error, phishing, loss  |
| Central custody    | Single point of failure     |
| Browser extensions | Malware & injection attacks |

At a high level, Tresori MPC secures your wallet and transactions using three invisible cryptographic layers. As a user, you never see private keys, seed phrases, or complex security steps, yet your assets remain protected by some of the strongest cryptography available.
