# Blacklist info The black list is a newline delimited file of wallet addresses. It can also support comments with the `#` character. ## Default Location By default, the harmony binary looks for the file `./.hmy/blaklist.txt`. ## Example File ``` one1spshr72utf6rwxseaz339j09ed8p6f8ke370zj one1uyshu2jgv8w465yc8kkny36thlt2wvel89tcmg # This is a comment one1r4zyyjqrulf935a479sgqlpa78kz7zlcg2jfen ``` ## Details Each transaction added to the tx-pool has its `to` and `from` address checked against this blacklist. If there is a hit, the transaction is considered invalid and is dropped from the tx-pool.
