Collecting Inscriptions and Ordinals with Sparrow Wallet

Users who cannot or have not yet set up the ord wallet can receive inscriptions and ordinals with alternative groestlcoin wallets, as long as they are very careful about how they spend from that wallet.

This guide gives some basic steps on how to create a wallet with Sparrow Wallet which is compatible with ord and can be later imported into ord

⚠️⚠️ Warning!! ⚠️⚠️

As a general rule if you take this approach, you should use this wallet with the Sparrow software as a receive-only wallet.

Do not spend any gros from this wallet unless you are sure you know what you are doing. You could very easily inadvertently lose access to your ordinals and inscriptions if you don't heed this warning.

Wallet Setup & Receiving

Download the Sparrow Wallet from the releases page for your particular operating system.

Select File -> New Wallet and create a new wallet called ord.

Change the Script Type to Taproot (P2TR) and select the New or Imported Software Wallet option.

Select Use 12 Words and then click Generate New. Leave the passphrase blank.

A new 12 word BIP39 seed phrase will be generated for you. Write this down somewhere safe as this is your backup to get access to your wallet. NEVER share or show this seed phrase to anyone else.

Once you have written down the seed phrase click Confirm Backup.

Re-enter the seed phrase which you wrote down, and then click Create Keystore.

Click Import Keystore.

Click Apply. Add a password for the wallet if you want to.

You now have a wallet which is compatible with ord, and can be imported into ord using the BIP39 Seed Phrase. To receive ordinals or inscriptions, click on the Receive tab and copy a new address.

Each time you want to receive you should use a brand-new address, and not re-use existing addresses.

Note that groestlcoin is different to some other blockchain wallets, in that this wallet can generate an unlimited number of new addresses. You can generate a new address by clicking on the Get Next Address button. You can see all of your addresses in the Addresses tab of the app.

You can add a label to each address, so you can keep track of what it was used for.

Validating / Viewing Received Inscriptions

Once you have received an inscription you will see a new transaction in the Transactions tab of Sparrow, as well as a new UTXO in the UTXOs tab.

Initially this transaction may have an "Unconfirmed" status, and you will need to wait for it to be mined into a groestlcoin block before it is fully received.

To track the status of your transaction you can right-click on it, select Copy Transaction ID and then paste that transaction id into mempool.space.

Once the transaction has confirmed, you can validate and view your inscription by heading over to the UTXOs tab, finding the UTXO you want to check, right-clicking on the Output and selecting Copy Transaction Output. This transaction output id can then be pasted into the ordinals.groestlcoin.org search.

Freezing UTXO's

As explained above, each of your inscriptions is stored in an Unspent Transaction Output (UTXO). You want to be very careful not to accidentally spend your inscriptions, and one way to make it harder for this to happen is to freeze the UTXO.

To do this, go to the UTXOs tab, find the UTXO you want to freeze, right-click on the Output and select Freeze UTXO.

This UTXO (Inscription) is now un-spendable within the Sparrow Wallet until you unfreeze it.

Importing into ord wallet

For details on setting up Groestlcoin Core and the ord wallet check out the Inscriptions Guide

When setting up ord, instead of running ord wallet create to create a brand-new wallet, you can import your existing wallet using ord wallet restore "BIP39 SEED PHRASE" using the seed phrase you generated with Sparrow Wallet.

There is currently a bug which causes an imported wallet to not be automatically rescanned against the blockchain. To work around this you will need to manually trigger a rescan using the groestlcoin core cli: groestlcoin-cli -rpcwallet=ord rescanblockchain 767430

You can then check your wallet's inscriptions using ord wallet inscriptions

Note that if you have previously created a wallet with ord, then you will already have a wallet with the default name, and will need to give your imported wallet a different name. You can use the --wallet parameter in all ord commands to reference a different wallet, eg:

ord --wallet ord_from_sparrow wallet restore "BIP39 SEED PHRASE"

ord --wallet ord_from_sparrow wallet inscriptions

groestlcoin-cli -rpcwallet=ord_from_sparrow rescanblockchain 767430

Sending inscriptions with Sparrow Wallet

⚠️⚠️ Warning ⚠️⚠️

While it is highly recommended that you set up a groestlcoin core node and run the ord software, there are certain limited ways you can send inscriptions out of Sparrow Wallet in a safe way. Please note that this is not recommended, and you should only do this if you fully understand what you are doing.

Using the ord software will remove much of the complexity we are describing here, as it is able to automatically and safely handle sending inscriptions in an easy way.

⚠️⚠️ Additional Warning ⚠️⚠️

Don't use your sparrow inscriptions wallet to do general sends of non-inscription groestlcoin. You can setup a separate wallet in sparrow if you need to do normal groestlcoin transactions, and keep your inscriptions wallet separate.

Groestlcoin's UTXO model

Before sending any transaction it's important that you have a good mental model for groestlcoin's Unspent Transaction Output (UTXO) system. The way Groestlcoin works is fundamentally different to many other blockchains such as Ethereum. In Ethereum generally you have a single address in which you store ETH, and you cannot differentiate between any of the ETH - it is just all a single value of the total amount in that address. Groestlcoin works very differently in that we generate a new address in the wallet for each receive, and every time you receive gros to an address in your wallet you are creating a new UTXO. Each UTXO can be seen and managed individually. You can select specific UTXO's which you want to spend, and you can choose not to spend certain UTXO's.

Some Groestlcoin wallets do not expose this level of detail, and they just show you a single summed up value of all the groestlcoin in your wallet. However, when sending inscriptions it is important that you use a wallet like Sparrow which allows for UTXO control.

Inspecting your inscription before sending

Like we have previously described inscriptions are inscribed onto gros, and gros are stored within UTXOs. UTXO's are a collection of gros with some particular value of the number of gros (the output value). Usually (but not always) the inscription will be inscribed on the first gro in the UTXO.

When inspecting your inscription before sending the main thing you will want to check is which gro in the UTXO your inscription is inscribed on.

To do this, you can follow the Validating / Viewing Received Inscriptions described above to find the inscription page for your inscription on ordinals.groestlcoin.org

There you will find some metadata about your inscription which looks like the following:

There is a few of important things to check here:

• The output identifier matches the identifier of the UTXO you are going to send
• The offset of the inscription is 0 (this means that the inscription is located on the first gro in the UTXO)
• the output_value has enough gros to cover the transaction fee (postage) for sending the transaction. The exact amount you will need depends on the fee rate you will select for the transaction

If all of the above are true for your inscription, it should be safe for you to send it using the method below.

⚠️⚠️ Be very careful sending your inscription particularly if the offset value is not 0. It is not recommended to use this method if that is the case, as doing so you could accidentally send your inscription to a groestlcoin miner unless you know what you are doing.

Sending your inscription

To send an inscription navigate to the UTXOs tab, and find the UTXO which you previously validated contains your inscription.

If you previously froze the UXTO you will need to right-click on it and unfreeze it.

Select the UTXO you want to send, and ensure that is the only UTXO is selected. You should see UTXOs 1/1 in the interface. Once you are sure this is the case you can hit Send Selected.

You will then be presented with the transaction construction interface. There is a few things you need to check here to make sure that this is a safe send:

• The transaction should have only 1 input, and this should be the UTXO with the label you want to send
• The transaction should have only 1 output, which is the address/label where you want to send the inscription

If your transaction looks any different, for example you have multiple inputs, or multiple outputs then this may not be a safe transfer of your inscription, and you should abandon sending until you understand more, or can import into the ord wallet.

You should set an appropriate transaction fee, Sparrow will usually recommend a reasonable one, but you can also check mempool.space to see what the recommended fee rate is for sending a transaction.

You should add a label for the recipient address, a label like alice address for inscription #123 would be ideal.

Once you have checked the transaction is a safe transaction using the checks above, and you are confident to send it you can click Create Transaction.

Here again you can double check that your transaction looks safe, and once you are confident you can click Finalize Transaction for Signing.

Here you can triple check everything before hitting Sign.

And then actually you get very very last chance to check everything before hitting Broadcast Transaction. Once you broadcast the transaction it is sent to the groestlcoin network, and starts being propagated into the mempool.

If you want to track the status of your transaction you can copy the Transaction Id (Txid) and paste that into mempool.space

Once the transaction has confirmed you can check the inscription page on ordinals.groestlcoin.org to validate that it has moved to the new output location and address.

Troubleshooting

Sparrow wallet is not showing a transaction/UTXO, but I can see it on mempool.space!

Make sure that your wallet is connected to a groestlcoin node. To validate this, head into the Preferences-> Server settings, and click Edit Existing Connection.

From there you can select a node and click Test Connection to validate that Sparrow is able to connect successfully.
