[\\[1\\]](#cite-id-eQ52BigDS8S2ftuA) \n\n## Overview\n\nWhatPay 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](https://iq.wiki/wiki/bitcoin), [Ethereum](https://iq.wiki/wiki/ethereum), [Solana](https://iq.wiki/wiki/solana), [Tron](https://iq.wiki/wiki/tron), and [Cosmos](https://iq.wiki/wiki/cosmos)-based ecosystems.\n\nThe 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\\]](#cite-id-eQ52BigDS8S2ftuA) \n\n## Products\n\nWhatPay 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.\n\n### MPC Wallet\n\nThe 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.\n\nThe architecture aims to reduce risks associated with single points of failure while maintaining user control over [digital assets](https://iq.wiki/wiki/digital-assets).

According to project materials, these components are designed to support secure key management and interaction with multiple blockchain ecosystems.\n\n### Multiparty Computation\n\nMultiparty 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.\n\nThis approach aims to reduce risks associated with key loss and single points of compromise.\nThis approach aims to reduce risks associated with key loss and single points of compromise.\n\n## Ecosystem\n\nThe WhatPay ecosystem consists of wallet users, supported blockchain networks, decentralized applications, and interoperability services.\nAccording 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.\n\n## Use Cases\n\nWhatPay is designed to support a variety of digital asset and Web3 interaction scenarios. Potential use cases include:\n\n* Multi-chain asset management\n* Self-custodial storage of digital assets\n* Cross-chain asset transfers\n* Interaction with decentralized applications\n* Access to decentralized finance protocols\n* Participation in prediction markets\n* Perpetual trading activities\n* Management of assets across multiple blockchain ecosystems\n* Wallet recovery through email and passkey mechanisms\n\n## Architecture\n\nThe architecture of WhatPay relies on multi-party computation and biometric security mechanisms:\n\n* MPC-based Key Management: Divides the keys into multiple shares stored separately, enhancing security by ensuring no single entity has complete access.\n* Device-Centric Authentication: Utilizes device hardware for biometric authentication (Face ID/Touch ID) to authorize transactions.\n* Cross-chain Support: Designed to interface with various blockchain networks, enabling diverse asset management through a single app interface.","summary":"WhatPay is a non-custodial multi-chain wallet featuring MPC security, allowing users to manage multiple cryptocurrencies securely without a seed phrase.","images":[{"id":"QmcSi5M2sN7wkirJkGpE1kjkimbKNisVyy9UoypcrttaH5","type":"image/jpeg, image/png"}],"categories":[{"id":"projects-and-protocols","title":"Projects & Protocols"}],"tags":[{"id":"Infrastructure"}],"media":[{"id":"QmeczGH3seKkb3TrBBrZBLjyqNJM2EdwPVKbfPtHy2c8Tm","size":null,"name":null,"type":"GALLERY","source":"IPFS_IMG"}],"metadata":[{"id":"references","value":"[{\"id\":\"eQ52BigDS8S2ftuA\",\"url\":\"https://whatpay.com\",\"description\":\"WhatPay Official Website\",\"timestamp\":1781776560856},{\"id\":\"M8LV6qB8NjHnycSI\",\"description\":\"Whatpay official X link\",\"timestamp\":1781796642718,\"url\":\"https://x.com/WhatPayGlobal\"}]"},{"id":"website","value":"https://whatpay.com"},{"id":"twitter_profile","value":"https://x.com/WhatPayGlobal"},{"id":"previous_cid","value":"\"https://ipfs.everipedia.org/ipfs/QmY7NvrGCZkFgobeh3wBGG3hESch85bp8BzRyGAVv2AFwh\""},{"id":"commit-message","value":"\"Updated title to Projects & Protocols and normalized wallet id casing\""},{"id":"previous_cid","value":"QmY7NvrGCZkFgobeh3wBGG3hESch85bp8BzRyGAVv2AFwh"}],"events":[],"user":{"id":"0x8af7a19a26d8fbc48defb35aefb15ec8c407f889"},"author":{"id":"0x8AF7a19a26d8FBC48dEfB35AEfb15Ec8c407f889"},"operator":{"id":"0x212Cb3F4aE6611054637f9f78F18fB628AD258bb"},"language":"en","version":1,"linkedWikis":{"blockchains":["bitcoin","ethereum","solana","tron"],"founders":["anon"],"speakers":[]},"recentActivity":"{\"items\":[{\"id\":\"dd48462a-82d7-44c7-ad86-3882f532d424\",\"title\":\"WHATPAY\",\"description\":\"WhatPay is a non-custodial multi-chain wallet featuring MPC security, allowing users to manage multiple cryptocurrencies securely without a seed phrase.\",\"timestamp\":\"2026-06-18T10:40:40.293Z\",\"category\":\"projects-and-protocols\",\"status\":{\"icon\":\"RiGlobalLine\",\"label\":\"Wiki Updated\",\"iconClassName\":\"text-green-500\"},\"user\":{\"name\":\"0x8af7a19a26d8fbc48defb35aefb15ec8c407f889\",\"address\":\"0x2D403Be9b67bE06FFEEb7C2681e19FB4D0eeA48b\"},\"button\":{\"label\":\"View Summary\",\"icon\":\"RiFileTextLine\"},\"summarySections\":[{\"title\":\"Action\",\"subtitle\":\"Added a new metadata field 'action'\",\"variant\":\"added\",\"changeCount\":1,\"changes\":[\"Added \\\"action\\\": \\\"CREATE\\\"\"]},{\"title\":\"ID\",\"subtitle\":\"Repository/content ID was replaced\",\"variant\":\"modified\",\"changeCount\":2,\"changes\":[\"Removed id \\\"QmRshNJ4HcAZSTKoirTBBA9vuim6GFVk5h6VFJWbZrGvV9\\\"\",\"Added id \\\"QmcSi5M2sN7wkirJkGpE1kjkimbKNisVyy9UoypcrttaH5\\\"\"]},{\"title\":\"Title\",\"subtitle\":\"Title text was changed\",\"variant\":\"modified\",\"changeCount\":1,\"changes\":[\"Changed title from \\\"WhatPay Pocket\\\" to \\\"WHATPAY\\\"\"]}]}]}"}
