Glossary

Depending on context, “THAT” may refer to:

• THAT token – the ERC-20 digital token described in this whitepaper (including bridged representations on other supported networks)

• THAT app – the non-custodial mobile wallet and related tooling that interfaces with public blockchains

• THAT COIN PTY LTD – the Australian company responsible for developing and maintaining the THAT app and related non-custodial tools

Where clarity is needed, this whitepaper uses “THAT token”, “THAT app” or “Company” rather than “THAT” alone.

Term	Definition
AML (Anti-Money Laundering)	Rules and procedures intended to reduce the risk that financial systems or services are used for criminal activity, such as money laundering or terrorism financing.
Blockchain	A distributed ledger technology where transactions are grouped into blocks, cryptographically linked and recorded across a network of computers.
Bridging Infrastructure	The combination of smart contracts, off-chain components and, in some cases, independent operators or validators that enable token bridging between networks (for example, between Ethereum and Polygon). Bridging infrastructure typically locks tokens on one network and issues or releases a corresponding representation on another.
Canonical (Token) Contract	The primary smart contract on a given blockchain that defines the official implementation of a token (for example, the ERC-20 contract for THAT on Ethereum). The canonical contract is treated as the reference point for total supply and core token behavior, even if representations of the token exist on other networks via bridges.
Circulating Supply	The number of tokens that have been released from vesting or lock-ups and are available to be held, transferred or traded by market participants.
Cryptocurrency / Digital Asset	A digital unit of value that uses cryptography for security and is typically recorded on a blockchain. In this whitepaper, “digital asset” is used broadly to refer to tokens and coins on public networks.
DEX (Decentralized Exchange)	A set of smart contracts that allow users to swap digital assets directly from their own wallets, without depositing funds with a centralized intermediary.
Digital Currency Exchange (DCE)	In Australia, a business that exchanges digital currency for money (or vice versa), or digital currency for digital currency, in the course of carrying on an exchange business. Certain DCE providers are required to register with AUSTRAC and comply with AML/CTF obligations. In this whitepaper, “DCE provider” refers to an independent exchange service integrated with or linked from the THAT app.
Fiat Currency	Government-issued currency that is not backed by a physical commodity, such as AUD, NZD, USD or GBP. Fiat currencies are legal tender in their respective jurisdictions and are distinct from digital assets like THAT.
Indexing Service	A third-party service that aggregates and organizes blockchain data (such as transactions and token transfers) to make it easier for applications like the THAT app to display balances, histories and other information without directly scanning the entire blockchain.
KYC (Know Your Customer)	Processes used by regulated service providers (such as exchanges) to verify a customer’s identity and comply with AML/CTF and related legal obligations.
Liquidity Provision	Supplying tokens to a trading venue (for example, a decentralized exchange pool) to enable swap between assets. Liquidity provision is typically governed by the rules of the relevant protocol or venue.
Non-Custodial Wallet	A wallet arrangement where users control their own private keys and digital assets directly. The wallet provider (for example, the THAT app) does not hold user funds or private keys on behalf of users.
Off-Ramp	A service that allows users to convert digital assets into fiat currency (for example, selling THAT or another token for AUD and withdrawing to a bank account).
On-Ramp	A service that allows users to convert fiat currency into digital assets (for example, buying THAT or another token using AUD through a DCE provider).
RPC Endpoint / Node Provider	A network access point (often run by a third-party service) that allows wallet applications to read data from, and broadcast transactions to, a blockchain network using remote procedure calls (RPC). The THAT app relies on such endpoints to query balances, transaction history and to submit signed transactions.
Seed Phrase (Mnemonic Phrase)	A human-readable sequence of words that encodes the information needed to recover a wallet’s private keys. Anyone who has the seed phrase can control the associated digital assets.
Smart Contract	Code deployed on a blockchain that can automatically execute predefined actions (for example, token transfers, swaps or vesting releases) when specified conditions are met.
Token	A type of digital asset issued on an existing blockchain (such as Ethereum or Polygon) via a smart contract, rather than being a standalone blockchain with its own native coin.
Token Bridging	The process of moving a token between two blockchain networks (for example, Ethereum and Polygon), usually by locking tokens on one network and minting or releasing a corresponding representation on another network.
Token Generation Event (TGE)	The point at which the initial supply of a token (such as THAT) is created and the main token contract is deployed on a blockchain.
Token Swap	Exchanging one digital asset for another, for example by using a decentralized exchange protocol from a non-custodial wallet.
Vesting Schedule	A time-based release arrangement under which tokens allocated to a particular category (such as founders, company or presale participants) are progressively made available over a defined period rather than all at once.
