SKALE Gas Token
sFUEL is the native token of SKALE. This is similar (but different!) to Ether in Ethereum. To interact with a SKALE chain, sFUEL tokens are required to conduct transactions. Unlike Ether and other gas tokens, sFUEL has no value: it’s FREE. There is no payment/cost required for transactions since sFUEL is FREE.
Getting sFUEL on a SKALE chain is done through a number of ways. Again because sFUEL is free and has no economic value, there is no way to purchase it or find it on exchanges.
The SKALE chain owner is allocated a massive amount of sFUEL and is responsible for distributing sFUEL to users in a way that’s best served for their users' experience. Some SKALE chain owners choose to send sFUEL to each user who completes an onboarding event. Other owners choose to provide a sFUEL faucet, and others allow users to mine gas natively in a browser. See https://github.com/skalenetwork/pow-demo for an example of mining gas on SKALE.
