Solidity supports inheritance between smart contracts, where Remix is like an alternative to Ganache, but also comes with a GUI to help navigate deploying and testing of Ethereum smart contracts. For address, put the address to … Users can deploy and call contracts on "GateChain" by simply switching to "GateChain" network. After this the detail page will look like the below: I make python bots for smart contracts, but I'm not too much of an expert. We also use the function that sends the address of the contract to the blockchain, so Web3 knows where to send it to.
