 ## Notes
+ ### Stealth Address
+  * Stealth Address documentation (to be updated soon) [here](https://github.com/ergoMixer/ergoMixBack/wiki/Stealth-Address).
+  * Use [this tool](https://ergomixer.github.io/stealth/) to generate a `new payment address` from any Stealth Addresses.

+ ### Breaking Change
   * From version `3.0.0 ` database scheme is changed; So, please consider binding to a different location if you have previously used an older version.
 
   * In order to buy SigmaUSD/SigmaRSV directly from the mixer, DO NOT SET withdrawal address when creating the mix/covert address and use "Set Later" option.
