How to use Reusable Payment Codes
Scan a payment code to open a payment channel - A payment channel will be created between both wallets by sending a special transaction on the blockchain. This is called a broadcast transaction and requires 1 network confirmation to confirm.
Tap to send - Once the broadcast transaction is confirmed the payment channel is open. Simply tap the channel name to send Groestlcoin directly to that wallet. No need to know their address.
Your wallet now has a Reusable Payment Code that you can share - Your payment code is unique to the wallet and never changes. You can publish and share your payment code without a loss of privacy for you or the sender.
No address needed - When your payment code is added by another wallet you will be able to receive Groestlcoin without ever sharing a Groestlcoin address. You can optionally send Groestlcoin back to the other wallet without sharing addresses.
Stealth Mode & Remote Commands
To remotely retrieve your wallet seed for backup/restore. Send an SMS to your phone with the following message: SW seed YOUR_PIN_CODE
You will receive the HEX seed of your wallet in response which you can use to restore access to your Groestlcoin.
To remotely wipe your wallet send an SMS to your phone with the following message: SW wipe YOUR_PIN_CODE
You will receive confirmation that the wallet has been securely wiped from the device.
If your phone is stolen and the thief has switched the SIM Card you can still initiate remote commands. With Sim Switch Defence enabled Groestlcoin Samourai will send your registered trusted number an SMS as soon as the SIM card is changed on your stolen phone. You can now send a remote wipe command to the new number.
While in Stealth Mode Groestlcoin Samourai will not appear on your phone home screen, app list, launcher, or recent apps. To open your wallet once it is in Stealth Mode you must dial a special code: **YOUR_PIN_CODE#
