A Guide to sFUEL: SKALE Network's Valueless Gas Token | SKALE

SKALE Network

What is sFUEL?

SKALE offers a practical approach to solving the issue of gas fees, which are a significant challenge in the blockchain world. SKALE provides a free to use experience, enabling users to transact seamlessly without the burden of escalating transaction fees.

To actualize this vision, SKALE introduced SKALE FUEL or sFUEL. This is the "gas" token that powers the SKALE blockchains and allows them to operate without traditional transaction costs.

It's important to clarify that while SKALE eliminates the cost associated with gas fees, the network is not "gasless" in a literal sense. sFUEL is still utilized as the gas token to power each transaction on the network. The term "gas-free" implies that users are not charged for transaction costs, but the transactions themselves still require a form of energy to be processed, in this case, sFUEL.

You may be asking: Without transaction fees, how are validators incentivized to run nodes? Instead of users paying transaction fees to validators, dApps pay validators on a monthly basis to support their SKALE AppChain. Learn more about how SKALE has zero gas fees.

Understanding sFUEL

Contrary to the traditional gas tokens such as ETH, sFUEL is valueless and specific to each SKALE Chain, meaning it can't be transferred between different SKALE Chains. However, there is a source for sFUEL distribution on all SKALE Chains. Note that it is different from SKL, which is SKALE’s native utility token.

The use of sFUEL as a token to power transactions serves also as a vital security role. By rate-limiting transactions through sFUEL, SKALE effectively curtails the risk of potential DDoS attacks and spam transactions. If there were no mechanism to control the flow of transactions, attackers could potentially flood the network with fake transactions disrupting service for legitimate users.

How to Obtain and Transact with sFUEL on SKALE

Transacting on SKALE using sFUEL is an intuitive experience, especially for those already familiar with performing on chain transactions through a wallet. The transaction process remains largely the same—the only difference is that on SKALE, the gas is obtained for free! As long as users have sFUEL in their wallets, they will always be able to transact on SKALE AppChains.

Acquiring sFUEL for Transactions

If you're wondering how to get sFUEL for your transactions, there's the sFUEL Station where you can obtain it for free. For a step-by-step guide, you can watch this video tutorial available on the dedicated documentation page.

For added convenience, dApps on the SKALE network can offer an automated sFUEL distribution within their platforms, ensuring that users always have what they need to transact without the need to manually request sFUEL from the sFUEL Station.
