+# Watch Only wallet
+
+## Monitor an onchain wallet and generate addresses for onchain payments
+
+Monitor an extended public key and generate deterministic fresh public keys with this simple watch only wallet. Invoice payments can also be generated, both through a publically shareable page and API.
+
+1. Start by clicking "NEW WALLET"\
+   ![new wallet](https://i.imgur.com/vgbAB7c.png)
+2. Fill the requested fields:
+   - give the wallet a name
+   - paste an Extended Public Key (xpub, ypub, zpub)
+   - click "CREATE WATCH-ONLY WALLET"\
+     ![fill wallet form](https://i.imgur.com/UVoG7LD.png)
+3. You can then access your onchain addresses\
+   ![get address](https://i.imgur.com/zkxTQ6l.png)
+4. You can then generate bitcoin onchain adresses from LNbits\
+   ![onchain address](https://i.imgur.com/4KVSSJn.png)
+
+You can now use this wallet on the LNBits [SatsPayServer](https://github.com/lnbits/lnbits/blob/master/lnbits/extensions/satspay/README.md) extension
