Understand the system.
This isn’t a list of crypto words. It’s the foundation you need to understand what XRPL is, what your wallet controls, how assets are identified, and what actually happens when you use the ledger.
What’s the XRP Ledger?
XRPL is a public ledger that keeps one shared record of accounts, balances, assets, offers, NFTs, settings, and transactions.
Forget the price chart for a minute. The ledger’s the actual system. It’s the public record everyone agrees on. When a transaction is validated, the ledger updates and that result becomes part of the shared history.
Public
Anyone can inspect addresses, transactions, balances, offers, and ledger objects.
Shared
Independent servers agree on the same ordered state instead of one company owning the database.
Final
Once your transaction is validated, there’s no customer-service desk that can reverse it for you.
Think of XRPL as the shared database underneath the apps. Xaman, exchanges, explorers, games, and marketplaces are interfaces. The ledger’s the record they’re reading and writing to.
Wallet, account, address, and keys
People use these words like they’re interchangeable. They’re connected, but they aren’t the same thing.
Account
The account’s the on-ledger identity holding balances, settings, and owned objects.
Address
The public identifier people use to send assets to your XRPL account. It starts with r.
Wallet App
The software that helps you view the account, build transactions, and sign them with your keys.
Private Keys
The secret authority that proves you control the account. Whoever controls the keys controls the account.
Seed
A human-manageable secret that can derive the keys. It’s not a password you can reset.
Exchange Balance
Usually an entry inside the exchange’s system. The exchange may control the actual on-ledger account.
Your wallet app doesn’t hold your assets like a physical wallet holds cash. The ledger records the account state. Your wallet holds the authority needed to control it.
$XRP vs issued assets
$XRP is native to XRPL. Issued assets are created by accounts and identified by both a currency code and an issuer.
| $XRP | Issued Asset |
|---|---|
| Native asset of the ledger | Created and issued by an XRPL account |
| No issuer address | Issuer address is part of its identity |
| No trustline needed | Trustline usually required |
| Used for reserves and transaction costs | Can represent stablecoins, loyalty points, game assets, claims, or project tokens |
| Can’t be frozen by an issuer | Issuer settings may allow freezing or authorization controls |
A token named XRP isn’t $XRP. Native $XRP doesn’t have an issuer. A fake token can copy a ticker and logo, but it can’t become the ledger’s native asset.
The issuer is part of the asset
On XRPL, the ticker alone doesn’t identify an issued asset. The real identity is currency code plus issuer account.
Both assets can display USD. That doesn’t make them equal. One issuer may redeem its token for real dollars. Another may be unknown, worthless, or malicious.
The ticker’s the name on the jersey. The issuer’s the identity of the player wearing it. Always verify both.
What’s a trustline?
A trustline is an on-ledger relationship between two accounts for one specific currency code.
A trustline tells XRPL that your account is willing to hold an issued asset connected to a specific issuer. It can include a limit and other settings. $XRP doesn’t use trustlines because it’s native to the ledger.

Currency: TOKEN
What a trustline doesn’t mean
- It doesn’t prove the token’s legitimate.
- It doesn’t mean the issuer owes you anything beyond its own stated terms.
- It doesn’t guarantee liquidity or value.
- It doesn’t give the issuer control of your $XRP.
Creating a trustline is permission to hold an asset. It isn’t an endorsement, investment guarantee, or security review.
Why some $XRP stays reserved
XRPL makes accounts hold a minimum amount of $XRP to discourage spam and unnecessary ledger objects.
Mainnet currently uses a 1 $XRP base reserve plus 0.2 $XRP for each qualifying owned ledger object. These values can change through validator fee voting, so software should query the network instead of hard-coding them forever.
Reserve calculator
Estimate the reserve for a simple account. Actual ownership and reserve behavior can vary by object type.
An NFT doesn’t always equal one owner-reserve item. XRPL stores NFTs in NFTokenPage objects, and each page can hold multiple NFTs. Don’t count individual NFTs as individual reserve objects.
Transactions and signing
A transaction is an instruction. Your signature proves the account authorized it.
Transaction
The structured instruction, such as sending a payment, creating an offer, or setting an account option.
Signature
Cryptographic proof that the transaction was authorized by a valid key for that account.
Sequence
A number that helps order transactions and stops the same signed transaction from being replayed repeatedly.
Fee
A small amount of $XRP destroyed by the transaction. It isn’t paid to an issuer or validator.
Validation
The point where the network agrees the transaction belongs in a validated ledger.
Metadata
The record showing what changed because of the transaction, including delivered amounts and affected objects.
Never sign based only on what a website button says. Read the transaction your wallet is asking you to approve.
DEX, offers, and AMMs
XRPL has native market infrastructure. Tokens can trade through order books, automated market makers, or paths using both.
DEX
The ledger’s decentralized exchange system. It tracks currency pairs when users create offers and make trades.
Offer
An on-ledger instruction offering one asset in exchange for another at a defined rate.
Order Book
The collection of open offers for a specific asset pair.
AMM
A liquidity pool that prices swaps through its pool balances instead of relying only on matching individual offers.
Liquidity
The real depth available to trade without causing extreme price movement.
Slippage
The difference between the price you expected and the effective result you receive.
A chart price isn’t proof that you can sell your whole position at that price. Liquidity decides what your exit can actually execute.
NFTs and ledger ownership
An XRPL NFT is a unique on-ledger token with its own identifier, flags, issuer, taxon, sequence, and optional transfer fee.
The NFT proves ownership of the on-ledger token. What that token represents depends on the project, metadata, legal terms, and utility connected to it.
NFTokenID
The unique identifier for the NFT on XRPL.
URI
An optional data field commonly used to point toward metadata or content.
Transfer Fee
An optional mint-time percentage that can return part of qualifying secondary-sale value to the issuer.
Offer
A buy or sell offer used to trade the NFT on-ledger.
Flags
Settings that can control whether the NFT is transferable and whether the issuer can burn it.
NFTokenPage
The ledger object that stores groups of NFTs owned by an account.
Owning an NFT doesn’t automatically give you copyright, company ownership, guaranteed utility, or a future buyer. Those rights have to come from the actual project terms.
What people keep mixing up
These mistakes are responsible for a massive amount of confusion and bad decisions.
Truth: Currency code plus issuer identifies an issued asset.
Truth: It only creates the account relationship needed to hold it.
Truth: The app manages access to the on-ledger account.
Truth: Some may be required for account and owner reserves.
Truth: Liquidity determines executable depth.
Truth: Failed transactions can still consume the transaction cost.
Truth: Validated ledger transactions are final.
Truth: XRPL transaction costs are destroyed.
