XRP Trust Lines Explained: How To Add One, And When Not To

An XRP trust line is your XRP Ledger account’s permission to hold one token from one issuer. You add one in a wallet such as Xaman, but only after checking that the issuer’s address matches the address the project publishes on its own website, and you skip it when the token arrived unasked, has no published issuer, or comes with a deadline.

Trust lines matter more each year because stablecoins and tokenized assets are arriving on the XRP Ledger, and none of them can sit in your account without one. This guide covers what a trust line is, why the issuer address is the part to check, how to add and remove one, and when to leave it alone. For the reserve math behind trust lines, see our explainer on the 0.2 XRP trust line reserve.

What is a trust line on the XRP Ledger?

A trust line is a link between your XRP Ledger account and one issuing account, for one token. The XRP Ledger documentation defines it as “a bidirectional relationship between two accounts for a single currency code.” XRP itself needs no trust line, because XRP is the ledger’s own asset and sits directly in your account.

Trust lines exist to protect the holder. According to xrpl.org, they “enforce the rule that you cannot cause someone else to hold a token they don’t want.” Each side of a trust line sets a limit, and that limit is zero by default.

The limit is the most of that token you are willing to hold on that line. Raising it does not buy anything. It only tells the ledger how much of that token your account will accept.

Why does the issuer address matter more than the token name?

The issuer address matters because anyone can create a token with any name. The XRP Ledger docs say: “Anyone can issue trust line tokens by sending a Payment transaction if the necessary trust lines are in place.” Two tokens can carry the same name and come from completely different accounts.

A token on the XRP Ledger has two halves:

Part	What it is	Can a copycat reuse it?
Currency code	The token’s name, such as USD or a longer code for names like RLUSD	Yes
Issuer address	The account that created the token	No

When you add a trust line, the transaction is called TrustSet. The XRP Ledger docs describe its issuer field as “the address of the account to extend trust to.” You are trusting an address, not a logo or a name.

A real project publishes its issuer address somewhere it controls. For example, Ripple’s stablecoin documentation lists the RLUSD issuer account on the XRP Ledger mainnet as rMxCKbEDwqr76QuheSUMdEGf4B9xJ8m5De. That is an example of where to look, not a recommendation to hold any token.

Does a trust line cost XRP?

A trust line costs no fee, but it locks some of your XRP as a reserve while it stays open. The XRP Ledger docs say “a trust line increases the XRP your account must hold in reserve,” because it takes up space on the ledger. As of October 2026, xrpl.org lists the owner reserve as 0.2 XRP per object on mainnet.

That XRP is not spent. You just can’t move it while the trust line exists. The docs add that the reserve “changes from time to time” through validator voting, so check the reserves page on xrpl.org for the current figure. Our guide to why you can’t send all of your XRP covers the account reserve as well.

The practical point: if you add a trust line for every token that shows up, more and more of your XRP gets set aside.

Can a token issuer freeze or claw back your tokens?

Yes, depending on how the issuer set up its account. The XRP Ledger docs on freezes say an issuer can restrict a single counterparty’s trust line, and they also state that XRP cannot be frozen. The rule applies to issued tokens, not to XRP.

Clawback is a separate setting. According to xrpl.org, “for regulatory purposes, some issuers need the ability to recover tokens after they are distributed to accounts.” An issuer must switch clawback on before it has any tokens or trust lines, so the setting is fixed from the start.

Neither feature is a red flag on its own. Regulated stablecoin issuers often need them. But you should know who holds those switches before you say yes. Our article on XRP Ledger clawback explains the setting in more detail.

How do you add a trust line in Xaman?

You add a trust line in Xaman from the token screen, after checking the issuer address against the project’s own site. Xaman’s help center lists these steps (labels may differ in the current version of the app):

1. Open Xaman and tap Add a token.
2. Pick from the Stable, Popular or Ecosystem lists, or search for the token.
3. Before you go further, open the project’s own website or documentation and find its published issuer address.
4. Compare that address with the one Xaman shows, character by character: the start, the middle and the end.
5. Tap Setup TrustLine.
6. Read the signing screen. It should show the transaction type (TrustSet), the issuer address and the limit.
7. Sign only if the issuer address matches. If it doesn’t, stop.

If you are new to the app, our Xaman wallet setup guide covers activating the account first.

When should you not add a trust line?

You should not add a trust line in four situations: the token came looking for you, the issuer address isn’t published anywhere you trust, you can’t tell who runs the issuer or what it can switch on, or someone is rushing you.

The first case is the most common. Xaman’s help center describes spam such as “a small XRP payment carrying a text memo that contains a URL, a token name, or a ‘claim your airdrop’ message.” Its advice is direct: “Do not click the links.” It also says “it is very important that you never sign a transaction you did not start yourself.”

The same page describes a second trick: a single unit of a token from an issuer you already trust. Xaman says to ignore it and not to send it back “to be polite.”

The reassuring part: Xaman says “spam cannot be used against you directly.” The danger starts only when you click, sign or reply. A real token will still be there tomorrow.

How do you remove a trust line and get the reserve back?

You remove a trust line by emptying it and then deleting it, which frees the reserved XRP. Xaman’s help center says, “Before you can remove a Trust Line, it must be empty.” Then tap the trust line, choose Remove token, confirm, and sign.

The XRP Ledger docs say trust lines are deleted automatically when both sides’ settings are back to default and the balance is zero. Once it’s gone, the reserve that line held is spendable again.

Four checks to run before any new trust line

Run these four checks every time. If any answer makes you pause, wait.

Check	Where to look	Stop if
1. Did you go looking for this token?	Your own intent	It arrived by airdrop, memo or message
2. Does the issuer address match?	The project’s own website or docs, and the signing screen	Any character differs, or no address is published
3. Can the issuer freeze or claw back?	The issuer’s documentation	You can’t find out, or you’re not comfortable with it
4. Is anyone rushing you?	The message or site	There’s a deadline or countdown

Keep a short list of the trust lines you hold and who issued each one. If you can’t name the issuer of a token in your wallet, that’s the one to look at first.

What to check next

Two things are worth watching. First, the reserve can change through validator votes, so the cost of each trust line can move. Second, the XRP Ledger also supports multi-purpose tokens (MPTs), a newer token type that doesn’t use trust lines, so some future tokens may arrive without this step. Whatever the format, the habit stays the same: check the issuer address, not the name.
