# Wallet as a Service

Wallet as a Service (WaaS) is a highly secure and scalable crypto wallet infrastructure, offering flexible options for digital assets management for businesses and institutions of all sizes. It's a digital wallet solution covering all the essential stress points of the modern digital wallet - the perfect balance between ease of use and security, successful and quick integration with multiple blockchains, key recovery system, and low-cost fees.

## Protected with MPC technology

The most secure key management method for signing transactions.

## How MPC works

MPC is a keyless system that replaces the private key with individual key shares separately generated by multiple non-trusting parties without sharing any data. This means no single party ever has access or visibility of the entire key. Transactions are signed, approved and broadcast with a single signature and the signers’ key shares never become public information, or even leave their holder’s domain.

## Quantum-safe cryptography

Our MPC Wallet features a Threshold Signature Scheme (TSS) which offers absolute protection of assets from external hacks and insider threats. With TSS, a threshold of active signers must be met before a transaction can be authorized. Thanks to the MPC, there is no way to know which signatories signed, so security and privacy are ensured.

## No single point of failure

Distributed risk and decentralized security minimize the possibility of theft or misuse.

## Sustainable and scalable

The blockchain agnostic nature of MPC is highly adaptable and easy to scale.

## Lower transaction fees

The advanced MPC method reduces transaction size, meaning lower gas and fees.
