When I try to transfer the token from 1 address to another, the error in the title pops up. Here is my relevant JS code: ($("#targetAddr").val() is the address of the target address (in metamask) and $("#amt").val() is the value of the tokens to transfer to.)
tokenContract.transfer($("#targetAddr").val().toString(),$("#amt").val())
I am using a smart contract that is very similar to OpenZepplin's ERC20. Its transfer is similar to ERC20's transfer function. What am I doing wrong?
Below is the code of my token contract setup in javascript:
var tokenContractAddress = token_contract_address;
//coinABI is the ABI from my smart contract.
var tokenContract = web3.eth.contract(coinABI).at(tokenContractAddress);
The address that is in the input is one of the addresses in my metamask account (essentially a valid address)
You need to construct an actual transaction with web3 or other framework you're using. Here is an example with web3: https://ethereum.stackexchange.com/questions/24828/how-to-send-erc20-token-using-web3-api
If you have a different version, go to their docs: https://web3js.readthedocs.io/en/v1.3.4/index.html
And see methods for sending a transaction to a contract.
You need to send a tx to the token contract that will call token's native transfer() method with neede arguments. you will need to sign this transaction and then send it.
