On the XRP Ledger (XRPL), a transfer can be accepted or rejected for four different reasons: the recipient may not be allowed to hold an issuer’s token, the destination account may reject deposits, the issuer may have frozen the token balance, or the issuer may have recovery authority through clawback. These controls apply differently to trust-line tokens and to XRP, so treating every XRPL payment as equivalent leads to incorrect designs and troubleshooting.
For a stablecoin issuer, the practical task is to choose controls before customers begin transacting, understand which account or asset each control governs, and explain the resulting exceptions to users and integrators. The settings do not prove that an off-ledger stablecoin is solvent or redeemable; they only govern ledger behavior.
Start with the XRPL asset model
Trust-line tokens are not XRP
XRPL-issued stablecoins and other fungible tokens are represented through trust lines. A trust line connects two accounts for a particular currency and carries a balance plus settings. The issuer’s account address and the currency code together identify the issued asset. A payment of that asset therefore depends on the relevant trust lines and issuer rules.
XRP is the ledger’s native asset. It does not use an issuer trust line, and it is not subject to token freeze or token clawback in the same way. Deposit Authorization is the important exception: because it is a destination-account rule, it can restrict incoming XRP as well as incoming tokens.

What XRPL evaluates during a transfer
A useful way to reason about a payment is to evaluate these questions in order:
- Which asset is moving? XRP follows native-payment rules; an issued stablecoin follows trust-line and issuer rules.
- Can the destination receive it? Deposit Authorization and any relevant destination restrictions are checked.
- Can the recipient hold the issued token? If the issuer uses Require Auth, the recipient’s trust line must be authorized.
- Is movement currently permitted? An issuer-level or trust-line freeze can prevent issued-token activity.
- Is the issuer using a recovery operation? Clawback, when enabled, gives the issuer a protocol-supported way to reclaim eligible issued tokens.
Issuer settings such as transfer fees, tick size and freeze-related options can also affect issued tokens. Those are token and issuer economics rather than a single universal “transfer switch.”
Require Auth: an issuer allow-list for token holders
What it controls
Require Auth lets an issuer decide which accounts may hold its trust-line tokens. A customer can create a trust line for the issuer’s currency, but the customer cannot hold that issuer’s balance until the issuer authorizes the line. This is an issuer-level allow-list: it applies to that issuer’s tokens and does not apply to XRP.

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsA common regulated-stablecoin onboarding sequence is for a customer to register, provide identity information, create a trust line and wait for the issuer’s authorization before receiving funds. The customer and issuer TrustSet transactions can occur in either order; authorization is what determines whether the line is permitted to hold the token.
Configuration timing and authorization lifecycle
Require Auth must be selected early. The issuer can enable it only while it has no trust lines and no offers. That prerequisite means an issuer should settle its compliance policy and deployment procedure before distributing the token or placing market offers.

Once a trust line has been authorized, the issuer cannot revoke that authorization while the trust line remains active. If the line returns to its default state and is automatically deleted, its authorization status is reset with the deleted line. This distinction matters when an account closes and later reopens a relationship: the issuer may need to authorize the newly created line again.
What a failed payment looks like
If Alice sends an issuer’s stablecoin to Bob and Bob’s trust line is not authorized, the payment cannot give Bob a usable balance. The fix is not to resend the same payment; Bob must complete the issuer’s onboarding requirements and the issuer must authorize the trust line. Authorization does not automatically bypass a separate Deposit Authorization rule on Bob’s account.
Deposit Authorization: a destination-account deposit rule
What it controls
Deposit Authorization (DepositAuth) is configured on the account that would receive funds. The XRPL documentation describes it this way: “Deposit Authorization is an optional account setting in the XRP Ledger.” When enabled, the account generally rejects transfers from strangers, including both XRP and issued tokens.
This is fundamentally different from Require Auth. Require Auth answers, “May this account hold this issuer’s token?” DepositAuth answers, “May this account receive a payment from this sender?” One is attached to an issuer’s token policy; the other is attached to a destination account.
Exceptions to the ordinary-payment rule
DepositAuth does not mean that no value can ever enter the account. Documented exceptions include:

- Receiving funds from a Check that the destination account itself cashes.
- Finishing an Escrow transaction that the destination account initiates or completes under the protocol’s rules.
For an ordinary Payment, the sender generally must be preauthorized when the destination has DepositAuth enabled. Integrators should therefore model authorization state explicitly instead of assuming that a valid destination address is sufficient.

Why DepositAuth needs careful testing
DepositAuth interacts with the rest of the ledger. Offers and trust lines without the No Ripple setting can provide other ways for balances to change, so “no one can pay this account” is an unsafe shorthand. Review the transaction-specific exceptions and the account’s trust-line and offer configuration before promising customers that an account is completely isolated from incoming balance changes.
DepositAuth is managed as an account setting with AccountSet. It is not an issuer permission on a particular stablecoin, and enabling it does not authorize a holder to receive every token. A destination can have DepositAuth enabled while still needing an issuer-authorized trust line for a specific currency.
Freeze and No Freeze: restricting movement after issuance
Individual and global freeze
An issuer that has retained freeze powers can freeze an individual trust line or globally freeze its issued trust-line tokens. A freeze changes whether issued-token balances may be used in transactions between holders. It does not apply to XRP.
Freeze behavior is not identical to destroying a balance. Under the documented behavior, direct transfers back to the issuer remain possible even when a holder’s token activity is frozen. Issuers should communicate exactly which paths remain available rather than telling customers that a frozen token has become completely immovable.

Freeze is not a reserve or redemption guarantee
A freeze is a ledger control. It does not make an issuer solvent, establish that reserves exist, or guarantee redemption of an off-ledger stablecoin liability. A compliance freeze can stop transfers while the issuer’s separate banking, custody and redemption obligations remain unresolved.
No Freeze is permanent
No Freeze permanently gives up the issuer’s ability to freeze trust lines and to disable Global Freeze. The choice cannot be reversed. No Freeze and trust-line clawback are mutually exclusive, so an issuer must decide whether it wants permanent immutability or future recovery authority before selecting either option.
Clawback: issuer recovery authority
What clawback does
Clawback is disabled by default for trust-line tokens. When it is enabled, the issuer can reclaim eligible issued tokens through the ledger’s clawback mechanism. XRP cannot be clawed back, because XRP is not an issuer-controlled trust-line asset.
Prerequisites before the first issuance
The issuer must enable Allow Trust Line Clawback before issuing any tokens. At that moment its owner directory must be empty: it cannot contain trust lines, offers, escrows, payment channels, checks or signer lists. The feature requires the Clawback amendment, and enabling it is irreversible.
These prerequisites make clawback a launch-time policy decision, not an emergency switch. Once customers, market offers or other owned ledger objects exist, the issuer cannot satisfy the “empty owner directory” condition merely by deciding that recovery would now be useful.

Clawback versus freeze
Freeze prevents or limits certain token activity; clawback changes ownership by reclaiming an eligible issued balance. They address different incidents. An issuer might freeze movement while investigating an account, then use clawback when its policy and the protocol conditions permit recovery. Neither control applies to XRP, and neither establishes the value of an off-ledger reserve.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Other AccountSet restrictions on incoming objects
AccountSet documents additional flags that block incoming checks, NFT offers, payment channels or trust lines. These settings target particular ledger objects and require the applicable protocol amendments. They should not be presented as a general replacement for DepositAuth: blocking an incoming check or trust-line creation does not, by itself, reject every ordinary Payment.
When implementing an account policy, keep the AccountRoot flag names separate from the AccountSet transaction flag values used to change them. They describe related settings but are not interchangeable field names. A transaction builder that copies one set of names into the other can produce an invalid or ineffective configuration.

Control comparison
| Control | Scope | Primary transfer effect | Timing and reversibility | Applies to XRP? |
|---|---|---|---|---|
| Require Auth | Issuer’s trust-line token | Only authorized trust lines may hold the token | Must be enabled while the issuer has no trust lines or offers; an active authorization cannot be revoked while that line remains active | No |
| DepositAuth | Destination account | Rejects ordinary deposits from unapproved senders, with documented exceptions | Configured as an account setting through AccountSet; behavior depends on sender authorization and transaction type | Yes |
| Individual or global freeze | Issuer’s issued trust-line tokens | Stops or limits token activity between holders; issuer-directed return paths remain documented | Available only while freeze powers are retained | No |
| No Freeze | Issuer policy | Removes the issuer’s ability to freeze trust lines and disable Global Freeze | Permanent and irreversible; mutually exclusive with trust-line clawback | No |
| Allow Trust Line Clawback | Issuer’s issued trust-line tokens | Permits reclaiming eligible issued balances | Must be enabled before issuance with an empty owner directory; irreversible and amendment-dependent | No |
Choosing a policy for a stablecoin issuer
Compliance-first issuance
If only verified customers may hold the stablecoin, Require Auth provides the holder allow-list. Pair it with an onboarding workflow that records identity review before the issuer authorizes each trust line. Test the case where a customer deletes a defaulted line and later creates a new one, because the new line’s authorization state is not inherited.
Controlled receiving accounts
If an account must reject unsolicited payments, use DepositAuth and maintain a preauthorization process for approved senders. Document the Check and Escrow exceptions and review trust-line and offer settings so operational staff understand every route by which a balance can change.
Recovery versus immutability
If the issuer needs a protocol-level recovery option for fraud, sanctions or mistaken distribution, it must choose clawback before issuance and cannot later select No Freeze. If the issuer instead promises that it will never freeze issued balances, No Freeze permanently records that choice and eliminates clawback compatibility. This is a governance decision as much as a technical one.
Diagnosing a rejected or unexpected transfer
| Symptom | Likely control | What to check |
|---|---|---|
| Recipient cannot receive an issued stablecoin | Require Auth or missing trust line | Confirm the recipient has the correct issuer-and-currency trust line and that the issuer authorized it. |
| Recipient rejects both XRP and tokens from a normal sender | DepositAuth | Check whether the sender is preauthorized and whether the transaction is one of the documented exceptions. |
| Token payment between holders fails while XRP payments work | Freeze or token-specific trust-line state | Inspect the issuer’s global and individual freeze status and the affected trust line; do not infer a problem with XRP. |
| An issuer cannot activate clawback after launch | Clawback prerequisites | Verify that Allow Trust Line Clawback was enabled before issuance and that the owner directory was empty at activation. |
| An account still changes balance despite DepositAuth | Ledger-object exception or Ripple setting | Review offers, trust lines without No Ripple and transaction-specific DepositAuth exceptions. |
Deployment checklist
- Classify every supported asset as XRP or an issuer-and-currency trust-line token.
- Decide whether token holding requires issuer authorization, and enable Require Auth before creating trust lines or offers if that is the policy.
- If clawback is required, enable Allow Trust Line Clawback before the first issuance while the owner directory is empty.
- Choose between retaining freeze powers and permanently selecting No Freeze; record that No Freeze cannot be undone and cannot coexist with trust-line clawback.
- For protected destinations, enable DepositAuth and define sender preauthorization, Check and Escrow handling, and support procedures for rejected Payments.
- Test ordinary Payments, preauthorized Payments, trust-line creation, issuer authorization, frozen balances, account closure and re-creation, and every documented exception on the target network.
- Keep AccountRoot flags, AccountSet transaction values and amendment requirements aligned with the current XRPL documentation before deploying to production.
The central design distinction is simple but consequential: Require Auth governs eligibility to hold an issuer’s token, DepositAuth governs deposits to a destination account, freeze governs movement of issued tokens, and clawback governs issuer recovery. Applying the right control to the right asset and lifecycle stage prevents most surprises in stablecoin and token transfers.
