Syfu

SyFu is a Web3 lifestyle application that converts users' real-world payment data into digital assets. The product combines a non-custodial wallet with a GameFi layer in which users nurture a "MANEKINEKO" (Japanese lucky cat) NFT in a Tamagotchi-style loop: linking card payment and check-in data levels up the NFT and distributes in-game tokens. Spending history is recorded on a decentralized network using Decentralized Identity (DID) and Soulbound Tokens (SBTs, non-transferable NFTs), which the project positions as portable, cross-border "universal credentials" and the basis of a decentralized consumer credit evaluation system.

The app economy uses two token types described by the project: Econ, an in-game token earned by binding payment and check-in data and spent on NFT development and game progression, and EVT (Excavation Token), a utility token used for NFT breeding and in-game payments that is described as being distributed in limited quantities across real-world merchants and mined by linking card payment data. EVT mining launched on 2025-04-03. Alongside the game, SyFu describes Web3 financial services including digital-asset management (DEX and staking), NFT trading through a planned SyFu marketplace, and digital-asset-backed payments. A third-party profile describes the wallet as using ERC-4337 account abstraction and MPC technology.

The app is distributed on iOS and Android; the Google Play listing is published by Unlock Lab Limited, based in Hong Kong, and reports over 1,000 downloads. The project self-describes as a "Payment Data DePIN" project originating in Japan.
