# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
