- Jan 13, 2022 · 3 years agoTo call a function from another contract in Solidity, you need to follow these steps: 1. Import the contract you want to call the function from using the `import` statement. 2. Create an instance of the imported contract using the `contractName contractInstance = contractName(addressOfContract)` syntax. 3. Call the function using the instance of the contract and the function name. Here's an example: ``` pragma solidity ^0.8.0; import './AnotherContract.sol'; contract MyContract { AnotherContract anotherContract = AnotherContract(addressOfAnotherContract); function callFunctionFromAnotherContract() public { anotherContract.functionName(); } } ```

You just need to import the contract you want to call the function from and create an instance of it. Then, you can simply call the function using the instance and the function name. Easy peasy, right? Here's an example: ``` pragma solidity ^0.8.0; import './AnotherContract.sol'; contract MyContract { AnotherContract anotherContract = AnotherContract(addressOfAnotherContract); function callFunctionFromAnotherContract() public { anotherContract.functionName(); } } ```
