i am looking for developer to create Bitcoin payment gateway that support all currency [. because coinbase commerce fees is so high ..]and Custom theme for xenforo
this would be quite expensive to build this... your looking at at least $300 just to start. you would have to query the blockchain for each transaction and save it in sql, multiple queries would be needed every n seconds for an alert system. and to tie it to the forum you would need some sort of unified vanilla blockchain api hopefully opensource that can be used with php.
