Hello! Please advise me on Solidity :) I have ERC20Burnable token, I want to perform operations with token in separate contract and burn it through burn() function. But this function is not in SafeERC20, how can i burn tokens from outside :)

Okey.
Look, I have a contract in which I exchange my ERC20 tokens. When I exchange my tokens for other crypto I want to burn them. My ERC20 token has the extension ERC20Burnable. I want to call burn() to reduce the totalSupply of my token. I can use IERC20 (SafeERC20) to handle the token, but there is no burn() function, how can I call burn function from my ERC20Burnable token from other contract.

call it from the token contract, not using safeERC20. so instead of "safeERC20.burn()" use "tokenContractName(contractAddress).burn()"

Depends on the context you're running it in? why cant you just call the burn method inside your contract after the exchange?

if the swap isn't directly connected you will need an interface

yes exactly. Is it directly connected?

you mean I need import my token contract ?

No, its different contracts

just put a basic interface in the contract to call your token

good idea, I try

interface iToken {
function burn() external;
}

^ literally all you need. just attach an address to that and it will work

yes exactly. Add an interface in your contract for the burn function, and attach the address of the token you wanna burn

anyway, more complex things. Has anyone implemented a call from a chainlinkRequest contract? to another contract?

interface iERC20Burnable {
function burnFrom(address account, uint256 amount) external;
}
Is working 👍👍👍👍
