# Managing sFUEL Distribution

> Options for distributing sFUEL to developers and users of your SKALE Chain

The default gas token of a SKALE Chain is SKALE Fuel (sFUEL). This gas token allows for a SKALE Chains to be fully Ethereum Virtual Machine (EVM) compatible while also offering [zero gas fees](/developers/gas-fees) to developers and end-users. While gasless transactions are recommended for most applications due to simple management; SKALE Chains running with sFUEL active will need to ensure developers and/or end-users can access the gas token to execute transactions.

## Etherbase

For SKALE Chain owners and operators, accessing sufficient sFUEL is critical.
All SKALE Chains come predeployed with a smart contract called **Etherbase** which is important for two reasons:

1. A large allocation of sFUEL is stored in this contract upon creation of the SKALE Chain, ensuring sufficient quantities are available for operators

2. sFUEL when consuemd in a transaction is automatically recycled into Etherbase ensuring that a SKALE Chain doesn't run out of gas

    ```ts theme={null}
     // Using Ethers v6
    import { Contract, JsonRpcProvider, Wallet, parseEther } from "ethers";

    const ETHERBASE_ABI = [
    	"function partiallyRetrieve(address payable receiver, uint256 amount) external",
    ];

    const ETHERBASE_PREDEPLOYED_ADDRESS = "0xd2bA3e0000000000000000000000000000000000";

    async function main() {	
    	const provider = new JsonRpcProvider("https://mainnet.skalenodes.com/v1/<SKALE Chain-name>");
    	const wallet = new Wallet(process.env.PRIVATE_KEY, provider);
    	const contract = new Contract(ETHERBASE_PREDEPLOYED_ADDRESS, ETHERBASE_ABI, wallet);
    		
    	// Allow anyone to deploy
    	const res = await contract.partiallyRetrieve(wallet.address, parseEther("25"));

    	console.log("Res: ", res); // Transaction Hash, once confirmed wallet.address native balance increases by 25
    }

    main()
    	.catch((err) => {
    		console.error(err);
    		process.exitCode = 1;
    	});
    ```

<Note>
  If you encouter any errors when trying to retrieve gas from Etherbase; this likely means that the address is missing `ETHER_MANAGER_ROLE`.

## sFUEL Station

SKALE Chains can request being added to the [sFUEL Station](https://sfuelstation.com). The sFUEL Station is currently availalable on SKALE Hub testnet and mainnet Chains: Calypso, Europa, Nebula, and Titan. The sFUEL Station allows users to put in their wallet and attain a small allocation of sFUEL to get started on a particular SKALE Chain.

<Note>
  While your chain may be added to the sFUEL Station upon request, this should not be a primary way to onboard users as it can increase the complexity of onboarding. You should utilize sFUEL Distribution within dApps when possible.
