Kovan USDC – Where to Find and Get Kovan USDC Testnet Tokens

You are writting a complex transfer function, the only difference is the sender cannot control the amount given away.

If you want to create a token faucet I'd make the recipient to send the transaction. Also having a cool down period of two minutes to limit possible abuse.

uint previous_giveaway;
uint last_giveaway;

function drip() returns (bool success) {
    // Only allow to drip every two minutes to limit abuse
    if (now - last_giveaway < 2 minutes) {
        return false;
    }
    last_giveaway = now;
    // deliver half than last time
    uint giveaway_value = previous_giveaway / 2;
    if (giveaway_value == 0){
        giveaway_value = starting_giveaway;
        previous_giveaway = starting_giveaway;
    }
    // It is a faucet mint new tokens
    balances[msg.sender] += giveaway_value;
    totalSupply += giveaway_value;
    Transfer(0x0, msg.sender, giveaway_value);
    return true;
}

To call that contract from a webapp using web3 v1.0 something like this should work

const token = new eth.Contract(abiToken, addressToken);
await token.methods.drip().send({ from: "address" });

The contract will deposit a few tokens to "address".

The best way i found was to use these resources:

https://docs.aave.com/developers/deployed-contracts/matic-polygon-market This gets you the token addresses

https://explorer-mumbai.maticvigil.com/address/0x341d1f30e77D3FBfbD43D17183E2acb9dF25574E/write-contract This allows you to write a contract to mint aave for example!

there are other ways you could create the contract to mint the tokens. You will spend MATIC for gas fees but its really not much.
