Let's suppose an existing Ethereum deployed contract.
I know the deployment Address and i have the contract's source code.
What i want to do is to call a function on this deployed contract from truffle console.
Is it possible and how can i do that ?
Thanks
Say you have a contract like the one below deployed at address 0x1f2deF1210B4D06B267A64b9888990734Aba7e24
pragma solidity ^0.8.1; contract test { string public initialString = "Hello World!"; function getString() public view returns (string memory) { return initialString; } } To create an instance of that contract:
truffle(develop)> contract = await test.at('0x1f2deF1210B4D06B267A64b9888990734Aba7e24') To call a function:
truffle(develop)> a = await contract.getString() To check the variable directly (if declared as public):
truffle(develop)> b = await.contract.initialString() This way, you will have in a and b the expected values.
Of course you need to point to the right Ethereum network within the truffle-config.js file in networks section.
