This enables customers to get better their bitcoin on various cellular, desktop or {hardware} wallets, no matter which pockets they used to generate the seed phrase. Taking an image or screenshot of your seed phrase will not be beneficial.
Selecting up the place you left off, you’ll most likely be on the immediate in your Passport asking you to improve the firmware. For the reason that Passport has not been related to the Envoy app but, this step will probably be skipped at this level and will probably be revisited after the seed phrase is created. You may replace the firmware utilizing the micro SD card at this level if you need to take action earlier than persevering with on to create your seed phrase. When you skipped the firmware replace for now, then choose “Create New Seed” on the Passport. You can be requested if you wish to generate a brand new seed phrase now, choose the test mark.

This completes the comparisons part. Within the subsequent part, you will notice how you can use choose options of the Passport.
Passport And Whirlpool
Whirlpool is a zero-link CoinJoin implementation supported by Samourai Pockets on Android cellular units and by Sparrow Pockets on Linux, Mac and Home windows desktops. Zero-link CoinJoin signifies that there aren’t any deterministic hyperlinks between the inputs and outputs of the CoinJoin transaction. As a result of a number of entities are concerned with every CoinJoin, there can’t be any certainty as to which entity owns which transaction output. CoinJoins can be utilized as a method to realize anonymity on a public blockchain, placing the choice to selectively reveal particulars about your self again in your palms, thus providing you with a layer of privateness separating your real-world identification from the transactions on a public ledger.
Passport helps Whirlpool accounts and this part will display how you can setu p and use this characteristic on Bitcoin’s testnet. All of the steps are the identical for Bitcoin’s mainnet.

Utilizing this method affords a pair advantages. First, every deposit to the Passport will appear like each different CoinJoin output to exterior observers on chain and, due to this fact, nobody aside from you’ll know that these unspent transaction outputs (UTXOs) are actually in chilly storage. So, as different CoinJoin individuals proceed mixing the opposite UTXOs out of your CoinJoin transactions, the forward-looking anonymity set of your UTXOs in chilly storage continues to develop.
One other profit is that the Whirlpool account on Passport was designed in such a approach you can import it to a scorching pockets at any time sooner or later and proceed mixing these UTXOs as free-riders in Whirlpool, thus saving your self from paying the coordinator charges a second time.

Sizzling Pockets
This information assumes you might have already put in Sparrow Pockets in your most popular desktop.

You’ll discover now that a number of tabs have appeared alongside the left-hand aspect of the person interface. These are the 4 accounts used to make Whirlpool work. The primary one is the deposit account the place you’ll want to ship bitcoin that you simply wish to CoinJoin. From the deposit tab, you possibly can click on on the obtain sub-tab to show a QR code for considered one of your receiving addresses and you may ship bitcoin to it.
After you have made a number of deposits to your scorching pockets, you possibly can click on on the UTXOs sub-tab to see your accessible outputs. Choose those you wish to CoinJoin or use the “Choose All” choice to make use of all of them. Simply understand that deciding on all will hyperlink all of those UTXOs collectively on chain within the subsequent step, previous to them being CoinJoined. If you don’t need them linked on chain, then simply combine one by one.
After you have your choice made, click on on “Combine Chosen”:
A window will pop up and, when you’ve got an SCODE for decreased coordinator charges, then you possibly can enter it right here. Then you possibly can choose your transaction precedence or, in different phrases, the quantity you’re keen to spend on mining charges. After you have these choices set, click on on “Subsequent”:
Then you possibly can select the pool measurement you wish to be a part of. There are 4 sizes to select from, the 100,000 sat pool measurement was used on this demonstration which is able to create 20 UTXOs which are all 100,000 sats every. The coordinator price for that is 5,000 sats. Click on on “Preview Premix” as soon as prepared:
Then you will notice a abstract of the transaction you simply constructed. This transaction is known as “tx0” and you’ll discover that all the chosen inputs of assorted sizes and from numerous addresses are consumed on this transaction and 20 like-sized outputs are created. These like-sized outputs from tx0 will probably be used as eligible inputs to Whirlpool CoinJoin transactions. There are three different outputs in a tx0 as nicely; the coordinator price, the poisonous change and the miners’ price. If the whole lot seems to be good, then click on on “Broadcast Premix Transaction”:
Then your pockets will ship your transaction to the Bitcoin community:

As long as your pockets is related to the web, then your accessible like-sized outputs in your premix account will probably be registered as eligible inputs for the coordinator to make use of in CoinJoin rounds. As extra individuals add liquidity, extra of your premix outputs will probably be CoinJoined. After going via a CoinJoin spherical, every UTXO will seem in your post-mix account, which you’ll view from the post-mix tab and the transactions sub-tab. As long as you allow your pockets open and related, the UTXOs in your post-mix account will stay accessible as eligible inputs to CoinJoin rounds as free-riders, the place they get combined time and again with no added charges to you:

You wish to be cautious about the way you deal with these outputs as a result of they’re linked on chain to any inputs used within the associated tx0 they got here from. For instance, do not ship some Whirlpool outputs and a few poisonous change to the identical tackle as a result of that will undo the anonymity advantages gained by utilizing Whirlpool.
Chilly Pockets
Now that you’ve got your scorching pockets established and a few bitcoin being CoinJoined in Whirlpool, you possibly can arrange the chilly pockets extension in your Passport. This would be the account you’re sending your CoinJoined outputs to for long-term chilly storage. Utilizing a separate seed out of your major chilly storage seed for this course of is beneficial. If you wish to import it to a scorching pockets at any time sooner or later and proceed mixing these UTXOs as free-riders, it’ll expose the seed to an web related gadget.
