1.2 About the SyFu Wallet
💡 Overview
The SyFu Wallet is a non-custodial wallet that does not require traditional private key management, utilizing MPC (Multi-Party Computation) technology.
In this system, user wallets are divided into two types: “Standard Wallet” and “Spending Wallet.” Both are non-custodial, meaning only the user has authority over the assets stored within the wallet.
SyFu never has the authority to store or transfer any user assets in either wallet.
🧩 How the MPC Wallet Works
The SyFu Wallet uses three-part distributed management for users’ private keys. Each key element requires a different authentication method for access.
Types of Authentication
Email Authentication (the email address registered when creating your SyFu account)
Phone Number Authentication or Google Authenticator
Passkey Authentication (biometric authentication such as Face ID or fingerprint)
By completing two out of these three authentications, users can access their wallet. Therefore, there is no need to back up or manually enter private keys as in traditional wallets.
Additionally, the SyFu Wallet never restores private keys unless the user explicitly requests it.
🔐 Wallet Structure and Roles
Each user is issued one wallet set, consisting of the following two types:
Standard Wallet
A non-custodial wallet used for external transfers and long-term storage. The user has full management authority.
NFT and token storage, external transfers
Spending Wallet
A non-custodial wallet built on smart contracts. Within the scope of the user’s signing authority, it automatically handles in-game transactions and reward settlements.
In-game economic activities such as check-ins, rewards, and NFT purchases
The Spending Wallet automatically processes transactions and balance management associated with in-game actions. Users do not need to manually sign or send transactions.
⚠️ Risks and Disclaimers
Both the Standard Wallet and Spending Wallet in the SyFu Wallet system are non-custodial. All asset movements are performed based on transactions signed by the user, and SyFu has no authority to store or transfer assets within the wallet.
If a user loses or incorrectly transmits their private key or signing authority, or if such information is leaked to a third party, SyFu shall not be held liable for any resulting losses.
🪪 About KYC (Identity Verification)
KYC (identity verification) is not required for normal use. However, in the following cases, users may be asked to complete identity verification:
Use related to SyFu Card
Legal identity verification may be required when issuing or using the card.
In cases of fraud or risk detection
Withdrawals or NFT transfers may be restricted and unlocked after identity verification.
🧭 Summary
The SyFu Wallet is a non-custodial MPC-structured wallet that distributes private key management.
Standard Wallet: for long-term storage and external transfers.
Spending Wallet: for in-game transactions, settlements, and reward management.
Asset movements are controlled by smart contracts and executed within the scope of user authorization.
SyFu does not store assets within the wallet and is not responsible for any losses due to private key loss.
