WhatPay is a multi-chain Web3 wallet that incorporates multiparty computation (MPC) technology, self-custodial asset management, and access to decentralized applications and blockchain services.

The wallet is designed to provide users with a unified interface for managing digital assets across multiple blockchain networks while maintaining control over private credentials. ^[1]

The platform integrates cross-chain functionality, account recovery mechanisms, and access to decentralized finance (DeFi) and other Web3 services. ^[1]

Overview

WhatPay is a self-custodial Web3 wallet that utilizes multiparty computation (MPC) technology for key management and account security. According to project materials, the wallet supports more than 35 blockchain networks, including Bitcoin, Ethereum, Solana, Tron, and Cosmos-based ecosystems.

The platform incorporates cross-chain asset management, account recovery mechanisms based on email authentication and passkeys, and access to decentralized applications. According to project materials, WhatPay is intended to serve as a gateway to a range of Web3 services and blockchain ecosystems. ^[1]

Products

WhatPay provides wallet infrastructure and blockchain services intended to support asset management and interaction with decentralized applications. These services are integrated into a single wallet interface.

MPC Wallet

The WhatPay wallet utilizes multiparty computation technology for key management. According to project materials, cryptographic control is distributed across multiple components rather than relying on a single private key.

The architecture aims to reduce risks associated with single points of failure while maintaining user control over digital assets. ^[1]

Multi-Chain Infrastructure

WhatPay supports more than 35 blockchain networks, including Bitcoin, Ethereum, Solana, Tron, and Cosmos ecosystems.

According to project materials, the platform is intended to provide users with a unified environment for managing assets across different blockchain networks.

Cross-Chain Services

The platform incorporates cross-chain functionality that enables users to transfer and exchange assets between supported ecosystems. According to project materials, these services aim to facilitate interoperability and asset movement across multiple blockchain environments.

Web3 Access

WhatPay provides access to decentralized applications and blockchain-based services through its wallet interface. Supported categories include decentralized finance applications, perpetual trading platforms, prediction markets, and other Web3 services.

Technology

The WhatPay technology stack combines self-custodial wallet infrastructure, multiparty computation, and cross-chain interoperability tools. According to project materials, these components are designed to support secure key management and interaction with multiple blockchain ecosystems.

Multiparty Computation

Multiparty computation (MPC) serves as the foundation of the wallet's key-management system. According to project materials, cryptographic control is divided across multiple parties rather than being dependent on a single secret.

This approach aims to reduce risks associated with key loss and single points of compromise. This approach aims to reduce risks associated with key loss and single points of compromise.

Ecosystem

The WhatPay ecosystem consists of wallet users, supported blockchain networks, decentralized applications, and interoperability services. According to project materials, ecosystem components include cross-chain asset services, DeFi protocols, perpetual trading platforms, prediction markets, and other Web3 applications integrated through the wallet interface.

Use Cases

WhatPay is designed to support a variety of digital asset and Web3 interaction scenarios. Potential use cases include:

• Multi-chain asset management
• Self-custodial storage of digital assets
• Cross-chain asset transfers
• Interaction with decentralized applications
• Access to decentralized finance protocols
• Participation in prediction markets
• Perpetual trading activities
• Management of assets across multiple blockchain ecosystems

Architecture

The architecture of WhatPay relies on multi-party computation and biometric security mechanisms:

• MPC-based Key Management: Divides the keys into multiple shares stored separately, enhancing security by ensuring no single entity has complete access.
• Device-Centric Authentication: Utilizes device hardware for biometric authentication (Face ID/Touch ID) to authorize transactions.
• Cross-chain Support: Designed to interface with various blockchain networks, enabling diverse asset management through a single app interface.
