Working on our first smart contract/token deployment. We're trying to avoid team tokens/marketing wallets/etc. and instead use a small transaction fee for the dev/team. We've tested in Ropsten, and thus far everything is working except the transaction fee piece (using an existing contract to get the steps down).
I noticed that many of these types of contracts have similar fee wallets - there are no ERC-20 token transactions, just internal transactions. Is this a specific type of wallet/address? Here's a quick example from this morning: https://etherscan.io/address/0x10d599336a3b8328875d29a12d3149fe52d5a149#internaltx
Any insight is appreciated.
