SKALE Chains enable dApps to run gasless transactions. This provides an effective way to scale your dApp not only for speed but also to scale economically. However, SKALE Chains do require sFUEL to conduct transactions – this sFUEL is a free gas token with no economic value, providing a way for dApps to facilitate permissive access to SKALE Chains and protects against DDoS attacks.

There are a few ways to get SKALE FUEL (sFUEL), depending on your setup.


For SKALE SDKs, an account is pre-allocated with SKALE FUEL (sFUEL). You can use this for conducting transactions, sending to users on your SKALE Chain, and more. See the README in the SDK for the pre-allocated account.
