Glossary
Stellar glossary for TDGOLD holders
Stellar has a handful of concepts that do not exist on other networks, and every one of them shows up the first time you try to buy Trump Digital Gold. Here they are without the jargon.
Trustline
An explicit opt-in stored on your account saying which asset, from which issuer, you agree to hold. Stellar accounts hold nothing they have not accepted, so without a trustline a payment to you simply fails. Each one reserves 0.5 XLM of your balance until you remove it.
Issuing account
The Stellar account that brought an asset into existence. Asset codes are not unique - many accounts can issue a token called TDGOLD - so the issuing account is the only thing that identifies a specific asset. Always compare it character for character.
Distribution account
A separate account that receives the whole supply from the issuer and handles all onward movement. Keeping it separate means the issuer can be locked immediately after issuance without freezing day-to-day operations.
Locked issuer
An issuing account whose master key weight has been set to zero. It can no longer sign anything: no new tokens, no change of home domain, no new signers, and no recovery of its own XLM. It makes a fixed supply a property of the ledger rather than a promise.
Home domain
A domain name stored on the issuing account itself. It is the on-chain half of the link between an asset and a website: the site claims the asset in stellar.toml, and the home domain confirms the site. Without it, anyone could publish a file claiming your asset.
stellar.toml (SEP-1)
A plain-text metadata file served at /.well-known/stellar.toml. It publishes the issuing account, supply, logo and organisation details that wallets and explorers read to display an asset properly.
Base reserve
The amount of XLM the network requires an account to keep, currently 0.5 XLM per reserve unit. A bare account needs two units, or 1 XLM. The reserve is not spent - it is released if the account entry it covers is removed.
Subentry
Anything attached to an account that consumes a reserve: a trustline, an offer on the order book, a signer, a data entry. Each subentry adds 0.5 XLM to the minimum balance, which is why a wallet planning to trade should hold more than the bare minimum.
SDEX
The Stellar decentralised exchange - an order book built into the protocol itself, not a separate contract or application. Any two assets with trustlines can be traded against each other directly from a wallet.
Liquidity pool
An automated market maker built into Stellar. Instead of matching against a resting order, a swap trades against a pooled reserve of two assets. Depositing into one creates a pool share trustline, which is itself a subentry.
credit_alphanum4 / credit_alphanum12
The two asset-code formats on Stellar. Codes of one to four characters are alphanum4; five to twelve characters are alphanum12. TDGOLD is six characters, so it is credit_alphanum12. The distinction matters because some explorer URLs and older integrations encode it.
Anchored asset
A token that represents a claim on something held off-chain, fiat in a bank or metal in a vault, with a named custodian, published attestations and a redemption process. Becoming one is phase four of the TDGOLD roadmap: when the custody, the audit and the redemption right are in place, the anchor fields in stellar.toml are where that becomes machine-readable.
Horizon
The HTTP API that exposes Stellar ledger data. Every claim on this site - supply, issuer flags, home domain, balances - can be read straight from a public Horizon node without trusting any website.
Stroop
The smallest unit on Stellar, one ten-millionth of an XLM. The base network fee is 100 stroops per operation, which is where the "fraction of a cent" figure comes from.
The two that matter most in practice are covered in depth elsewhere: trustlines in the buying guide, and issuing accounts in how to verify the asset.
