[Toucan's testnet faucet](https://faucet.toucan.earth/) allows you to obtain small amounts of carbon test tokens.&#x20;

* Make sure you are on the [Alfajores](https://chainlist.org/?testnets=true\&search=alfajores) testnet.&#x20;
* Use [Chainlist](https://chainlist.org/) to add the test networks to your [MetaMask](https://metamask.io/) wallet in case you haven't done that.&#x20;
* Make sure you have testnet tokens from the relevant blockchain to be able to pay for the gas when getting Toucan test tokens. For CELO tokens try either the [Celo faucet](https://faucet.celo.org/) the [AllThatNode](https://www.allthatnode.com/faucet/celo.dsrv) faucet.
