THAT App (Digital Wallet)

This section provides an overview of the THAT app, a non-custodial mobile wallet that allows users to hold, view and transact supported digital assets, including THAT, on public blockchains.

The THAT app is designed to provide a secure, user-friendly interface for managing digital assets. It focuses on helping users create and manage wallets, view balances and history, discover independent merchants that choose to accept digital assets and prepare transactions for broadcast to supported networks.

Key Characteristics

Non-custodial wallet

The THAT app operates as a non-custodial interface. Users generate and control their own wallet keys. The Company does not have access to users’ mnemonic (seed) phrases or private keys and cannot restore access if those keys are lost or compromised.

Wallets are typically protected on-device by a combination of:

• a mnemonic (seed) phrase generated when a wallet is created, and

• local device-level protections (such as PIN, passcode, biometric security and operating system–level encryption), where supported.

Private keys are stored locally on the user’s device in encrypted form and are used to sign transactions on-device. Transactions are then broadcast to the relevant blockchain network.

The THAT app is not a remittance service, card scheme, account-based payment product or other non-cash payment facility operated by the Company. It is a user-side interface that allows people to hold their own keys and construct transactions that are then executed directly on public blockchains, in the same way they could using other compatible non-custodial wallets.

Core Functions

View balances and transaction history

Users can see the balances of supported digital assets associated with their wallet addresses, as reported by the relevant blockchains and indexing services. The app also provides basic transaction history to help users review past activity.

Send and receive digital assets

Users can prepare and broadcast transactions to send supported digital assets (including THAT) to other wallet addresses, and can receive assets by sharing their own address or displaying a QR code. Value moves directly between the sender’s and recipient’s addresses on-chain; the Company does not intermediate, clear or settle these transfers.

Merchant discovery

The THAT app may include an informational directory where independent merchants can indicate that they accept THAT or other supported digital assets. Users can browse these listings to discover businesses that choose to accept digital assets and can use the app to prepare transactions to the merchant’s nominated on-chain address or tag. A merchant appearing in the directory does not need to use the THAT app or the THAT token. Merchants can share any compatible wallet address or tag they choose, and may accept any digital assets they decide to. The directory is intended as an informational listing only, not as a payment facility or escrow service.

Any decision to accept digital assets is made solely by each merchant. Inclusion in the directory does not constitute an endorsement by the Company, and the Company does not guarantee that any listed merchant will continue to accept any particular asset.

The THAT app may also include a simple, community-driven marketplace where users can list goods or services they wish to offer and share their preferred contact and payment details. Any such marketplace is intended as a way for users to find each other and arrange peer-to-peer transactions directly. The Company does not act as an escrow agent, does not guarantee the performance of any listing or transaction, and does not intermediate payments; any agreements are between the users involved and are settled directly on public blockchains or through other arrangements they choose.

Token swaps (interface to DEX protocols)

Where supported, the THAT app may provide an interface to third-party decentralized exchange (DEX) protocols or aggregators, allowing users to swap between THAT and other supported digital assets on a self-custody basis.

Any such swaps occur directly on public blockchains via third-party smart contracts. The Company does not operate an exchange or order book, does not act as a counterparty to these swaps, and does not guarantee execution, pricing or the availability of any particular trading pair.

Bridging between networks

For networks where bridging is supported, the THAT app may provide an interface to bridging infrastructure that enables users to move THAT between compatible networks (for example, between Ethereum and Polygon). As described in the Bridged Tokens and Network Risk section, bridging involves additional technical and operational considerations compared with holding tokens on the canonical Ethereum contract.

The availability of bridging, supported networks and specific mechanisms may change over time.

Security and Key Management

On-device encryption and signing

Sensitive wallet data (including private keys) is stored locally on the user’s device in encrypted form. Where supported by the device and operating system, the app may make use of secure hardware modules or system-level key stores to help protect this data. Blockchain transactions are signed on the user’s device, and private keys are not transmitted from the device.

Backups and recovery

Users are responsible for creating and maintaining secure backups of their mnemonic (seed) phrase and any other recovery information. The Company encourages users to:

• create offline backups of their seed phrase (for example, writing it down and storing it in a safe place), and

• avoid keeping seed phrases in cloud-synced, easily accessible formats such as screenshots or unencrypted notes.

Where supported by device manufacturers or operating systems, the THAT app may provide optional interfaces to system-level backup or key-management services (for example, device-encrypted backups controlled by the user). Any such features, if offered, are optional and are controlled by the user. They do not give the Company access to users’ keys.

User Experience

The THAT app is designed to be usable by both newcomers and experienced digital asset users. The interface is intended to:

• present key information (balances, recent activity, merchant listings) in a clear format

• reduce unnecessary jargon where possible, and

• provide straightforward flows for common tasks such as viewing a receiving address, preparing a transaction or initiating a swap via supported protocols.

Features, supported networks and integrations may evolve over time as the project develops, and not all features will be available in all regions or on all devices.

The Company cannot restore access to a wallet if a user loses their mnemonic phrase or private keys and does not guarantee the security of any particular storage method or third-party service.
