Overview
Create secure MPC wallets, sign transactions, sponsor gas, and recover accounts across multiple chains in a flexible custody model fro your users.
What Are Smart Wallets?
Smart Wallets provide everything required to build production-grade wallet experiences without handling private keys directly.
Instead of relying on browser extensions or storing private keys in your backend, Smart Wallets use Multi-Party Computation (MPC) to enable secure transaction signing without reconstructing a private key.
Each wallet consists of independently managed MPC shares. Client shares remain under your control and are only provided during signing operations, while Tatum manages the corresponding share required to participate in the MPC protocol. This enables the following :
Non-Custodial Ownership
Secure Transaction Signing
Gasless Onboarding
Backup & Recovery
Multi-Chain Support

Whether you're building fintech products, consumer apps, trading platforms, AI agents, gaming applications, or enterprise infrastructure, Smart Wallets provide a secure foundation for blockchain interactions.
