it's interesting! What is the algo again that derives adress from secrect phrase, and how does it give '9' such funny properties?
https://github.com/JinnLabs/SaM/blob/master/src/SaM.java:
Note that the hash of the empty string is all zeros, this can be used in cases when the hash of NULL should be NULL.
"9" is treated as "all zeros"/NULL.
The java version of the algo seems to look more professional than the javascript one ;-)
