(As a reminder, this only applies to issued tokens, not XRP.) This tutorial shows how to enable the No Freeze setting on your issuing account. ## Prerequisites - You need a connection to the XRP Ledger network. As shown in this tutorial, you can use public servers for testing. - You should be familiar with the Getting Started instructions for your preferred client library. This page provides examples for the following: - **JavaScript** with the [xrpl.js library](https://github.com/XRPLF/xrpl.js/). See [Get Started Using JavaScript](../../javascript/build-apps/get-started.md) for setup steps. - You don't need to have [issued a token](issue-a-fungible-token.md) in the XRP Ledger to enable No Freeze, but the main reason you would do so is if you intend to or have already issued such a token. ## Example Code Complete sample code for all of the steps of this tutorial is available under the [MIT license](https://github.com/XRPLF/xrpl-dev-portal/blob/master/LICENSE). - See [Code Samples: Freeze](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/freeze/) in the source repository for this website. ## Steps ### 1. Get Credentials To transact on the XRP Ledger, you need an address and secret key, and some XRP. If you use the best practice of having separate ["cold" and "hot" addresses](../../../concepts/accounts/account-types.md), you need the **master keys** to the _cold address_, which is the **issuer** of the token. Only the issuer's No Freeze setting has any effect on a token. **Caution:** You cannot use a [regular key pair](../../../concepts/accounts/cryptographic-keys.md) or [multi-signing](../../../concepts/accounts/multi-signing.md) to enable the No Freeze setting. For this tutorial, you can get credentials from the following interface: {% partial file="/docs/_snippets/interactive-tutorials/generate-step.md" /%} When you're building production-ready software, you should use an existing account, and manage your keys using a [secure signing configuration](../../../concepts/transactions/secure-signing.md). ### 2. Connect to the Network You must be connected to the network to submit transactions to it. The following code shows how to connect to a public XRP Ledger Testnet server a supported [client library](../../../references/client-libraries.md): {% tabs %} {% tab label="JavaScript" %} {% code-snippet file="/_code-samples/get-started/js/base.js" language="js" /%} {% /tab %} {% /tabs %} For this tutorial, click the following button to connect: {% partial file="/docs/_snippets/interactive-tutorials/connect-step.md" /%} ### 3. Send AccountSet Transaction To enable the No Freeze setting, send an [AccountSet transaction][] with a `SetFlag` field containing the [`asfNoFreeze` value (`6`)](../../../references/protocol/transactions/types/accountset.md#accountset-flags). To send the transaction, you first _prepare_ it to fill out all the necessary fields, then _sign_ it with your account's secret key, and finally _submit_ it to the network. For example: {% tabs %} {% tab label="JavaScript" %} {% code-snippet file="/_code-samples/freeze/js/set-no-freeze.js" from="// Submit an AccountSet transaction" before="// Done" language="js" /%} {% /tab %} {% tab label="WebSocket" %} ```json { "id": 12, "command": "submit", "tx_json": { "TransactionType": "AccountSet", "Account": "raKEEVSGnKSD9Zyvxu4z6Pqpm4ABH8FS6n", "Fee": "12", "Flags": 0, "SetFlag": 6, "LastLedgerSequence": 18124917, "Sequence": 4 }, "secret": "s████████████████████████████" } ``` {% /tab %} {% /tabs %} {% interactive-block label="Send AccountSet" steps=$frontmatter.steps %} {% loading-icon message="Sending" /%}
{% /interactive-block %} ### 4. Wait for Validation Most transactions are accepted into the next ledger version after they're submitted, which means it may take 4-7 seconds for a transaction's outcome to be final. If the XRP Ledger is busy or poor network connectivity delays a transaction from being relayed throughout the network, a transaction may take longer to be confirmed. (For information on how to set an expiration for transactions, see [Reliable Transaction Submission](../../../concepts/transactions/reliable-transaction-submission.md).) {% partial file="/docs/_snippets/interactive-tutorials/wait-step.md" /%} ### 5. Confirm Account Settings After the transaction is validated, you can check your account's settings to confirm that the No Freeze flag is enabled. You can do this by calling the [account_info method][] and checking the value of the account's `Flags` field to see if the [`lsfNoFreeze` bit (`0x00200000`)](../../../references/protocol/ledger-data/ledger-entry-types/accountroot.md#accountroot-flags) is enabled. {% tabs %} {% tab label="JavaScript" %} {% code-snippet file="/_code-samples/freeze/js/check-no-freeze.js" from="// Request account info" before="await client.disconnect()" language="js" /%} {% /tab %} {% tab label="WebSocket" %} ```json Request: { "id": 1, "command": "account_info", "account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn", "ledger_index": "validated" } Response: { "id": 4, "status": "success", "type": "response", "result": { "account_data": { "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn", "AccountTxnID": "41320138CA9837B34E82B3B3D6FB1E581D5DE2F0A67B3D62B5B8A8C9C8D970D0", "Balance": "100258663", "Domain": "6D64756F31332E636F6D", "EmailHash": "98B4375E1D753E5B91627516F6D70977", "Flags": 12582912, "LedgerEntryType": "AccountRoot", "MessageKey": "0000000000000000000000070000000300", "OwnerCount": 4, "PreviousTxnID": "41320138CA9837B34E82B3B3D6FB1E581D5DE2F0A67B3D62B5B8A8C9C8D970D0", "PreviousTxnLgrSeq": 18123095, "Sequence": 352, "TransferRate": 1004999999, "index": "13F1A95D7AAB7108D5CE7EEAF504B2894B8C674E6D68499076441C4837282BF8", "urlgravatar": "http://www.gravatar.com/avatar/98b4375e1d753e5b91627516f6d70977" }, "ledger_hash": "A777B05A293A73E511669B8A4A45A298FF89AD9C9394430023008DB4A6E7FDD5", "ledger_index": 18123249, "validated": true } } ``` {% /tab %} {% /tabs %} {% interactive-block label="Confirm Settings" steps=$frontmatter.steps %} {% loading-icon message="Sending" /%}
