Algorithm for starting to accept payments in BTC?

I'm a developer and run a full node of Bitcoin.
I have several shops where I plan to start accepting bitcoin payments. The volume I invision in the beginning would be rather small.
(1) What'd be a simple algorithm for how to get started with it?
Would I have to generate (N of shops * 100) addresses first? And then map each of 100 to a shop? And then at checkout give a user one of those addresses and then watch when the 1st confirmation arrives, by doing poll requests from my shop to my full node server, remotely, via RPC?

(2) Also, how would I actually properly create a wallet for this? I'll need that wallet to be watch-only.
(3) Would I be able to somehow connect my Electrum client-wallet to that bitcoin watch-only wallet so that I could see how much of bitcoins there're in it, from my laptop in a more convenient manner?

---
I don't consider third-party solutions such as BTC server or Electrum server. I use Electrum as a wallet only, on desktop.

Watch only balance not spendable in bitcoin core?

I'm trying to do the walletcreatefundedpsbt thing in the console and/or push the Create Unsigned button on the spend tab.
This wallet was created as watch-only-only and has an imported address. The (nonzero) address balance does show up on the bottom right of the send tab, but when I hit the "Use available balance" button it says I have zero. When I try to do walletcreatefunded psbt it says I have insufficient funds.
It's like it refuses to spend create a PSBT with the watch only funds.
Help?
Edit: Got it. It needed the script for the input.
importmulti the "desc" field resolved my issue.

UPDATE: This has been an issue with Sentinel, everything is working fine again!
u/SamouraiWallet u/SamouraiWalletDev u/yilmzfurkan
This had me panicking yesterday evening since Sentinel displayed my balance as 0. Copied my public keys all over the place to test it with other apps, please let us know in thus sub next time!
Used sentinel for over a month to monitor my balance using the master public key shown of my cold card in Electrum.
Worked fine but just today it failed to load my balance, and kept loading forever, so I reinstalled the app, opened my electrum wallet (skeleton wallet, generated on cold card)
and when I used the information option to display my master pub key it displayed my zpub key, I used the qr code option but sentinel fails to add it and the mobile electrum wallet won't let me use it as well...

Used it for a month just fine before.... Really worried now that something is wrong with my keys. What could be the issue, why does no wallet let me monitor my zpub key all of sudden?
Electrum is still showing my correct balance though....

Xpub from Ledger Live does not create watching-only wallet of Ledger bitcoin account on phone.

I got the xpub for the bitcoin account on my Ledger Nano S and created a watching-only wallet on my phone. The Ledger has bitcoin in the account but the watching-only wallet doesn't have any bitcoin, transactions, and the addresses are all different (bc1... addresses on Ledger and 1... on phone). What happened?

I have $4200 in bitcoin but it’s “non-spendable”. Does anybody know how to take it since it was sent to me from an imported address as “watch only”?

submitted by JavanHammer to Bitcoin [link] [comments]

Guys, don't get fooled both by the current prices and future predictions good or bad. Bitcoin alone obviously cannot carry the entire crypto payment industry [LN or not]. The competition against Bitcoin is ongoing and is getting only stronger. Watch this space!

How to add a Trezor wallet to Bitcoin Core as watch-only

I wanted to use Bitcoin Core to keep an eye on transactions (basically using your own full Bitcoin node to validate, instead of "trusting" Satoshilabs and their webwallet). This doesn't mean there's anything wrong with Satoshilabls' trezor web wallet - it's just a matter of being totally sovereign/independent - if you want that, then using your own Bitcoin Core full node is a must.
Spent some time investigating how to do that, so sharing here in case someone wants it. Feel free to point any ways to do it better.
How-To:
  1. Go to the usual Trezor wallet site, then open the wallet you want to import to Core (don't forget passphrase if needed). Copy the ypub text string.
  2. Convert the ypub to xpub using something like this: https://jlopp.github.io/xpub-converte You can save the page and run it offline/airgapped in something like Tails if you don't trust it. There is no security risk (not a private key) but only privacy risk (with your public keys the site can see all transactions/balances of that wallet)
  3. Put the xpub in a Core RPC importmulti command with this formatting:
    importmulti '[{"range": [0, 1000], "timestamp": "now", "keypool": true, "watchonly": true, "desc": "wpkh([000000f1/84h/0h/0h]your_xpub_goes_here/0/)#7x87wdy3", "internal": false}, {"range": [0, 1000], "timestamp": "now", "keypool": true, "watchonly": true, "desc": "wpkh([000000f1/84h/0h/0h]your_xpub_goes_here/1/)#0jzlnc5f", "internal": true}]'
Then open Bitcoin Core and do these other steps...
  1. In File>Create Wallet, create a wallet with "No Encryption" & "Watch Only" - call it anything you like (TrezorA for example).
  2. Open Window>Console, select the wallet you just created (on the pull-down menu at the top) and then paste the importmulti command where you put your xpub.
  3. Core will complain that the checksum is wrong (the "7x87wdy3" and "wdxy2s2t" parts in my example) replace them with the right ones shown in the message and retry.
  4. You should see the wallet imported with success, but with no transaction history. It is necessary to rescan the chain to index the transactions that wallet made. To save time, you can use the blockheight of the first block where you made a transaction with that trezor, for example: "rescanblockchain 590500".
You can find out the block by putting the hash of your first transfer in a block explorer like https://live.blockcypher.com/, look for "blockheight" If you have no idea which block has your first transaction, you can just rescan the whole chain by typing "rescanblockchain 0" in the console (but Core will take way longer to do it).
That's about it, all transactions made from what wallet should then appear in Core and it will warn every time funds are received or spent. You can be running your own full node and constantly monitoring your wallet, without having to use the Trezor or load Satoshilab's site.
You cannot spend from that wallet in Core, but you can use it to generate receive addresses and send to it (keep in mind that if you generate bech32 addresses in Core, those transfers will not appear at Trezor wallet since it doesn't support it yet :| )
Edit: Forgot change addresses, fixed importmulti example.
