No response from live networks except ganache when interacting with truffle-contract

I am developing a Web3 app for a private Ethereum network. Throughout the development I used ganache-cli and now I wanted to test in the private live network. I can successfully interact with the network at the ganache network. I deployed the contract successfully to the live network. I see the transaction being mined successfully…

I am using already deployed tokens in my contract

My question is if I’m not implementing ERC-20 methods in my contract, but I’m using already deployed ERC-20 contract methods in my contract, so can we say this will be ERC-20 compliant contract? contract MyContract is Owned { event Created ( uint256 tradeId, uint256 createdAt, uint256 expiredAt, address originatorAddress, address benificiaryAddress, string expectedToken, uint256 receivedQty);…

raw transactions to send ERC20 token fails on private network(POA)

Where can I get list of tokens that allow direct conversion to ether and not just from token to token?

Most tokens simply utilize the ERC20 functions transferfrom/transferto which just use some balances to add from one user to another – but what are the ones who allow you to: buy token cashout to ether such as: withdraw (msg.sender.transfer (tokensbought);) Can something like this be done with WETH somehow? (wrapped ether). I am just looking…
