Refuel helps users arrive on the destination chain with the gas they need for their next action. During a Socket-routed transfer, the route can include a small amount of destination-chain native token so the user is not stranded after the swap or bridge completes.

​
Why it matters

Cross-chain transactions often leave users with the right asset but no destination gas. Refuel reduces that friction by bundling destination gas into the same routed experience. Use Refuel when your product needs to:
  • Move users into a new chain and prepare them for the next transaction.
  • Reduce support issues caused by users receiving funds without native gas.
  • Build onboarding, checkout, account funding, or trading flows that continue on the destination chain.

​
How it works

Socket evaluates routes that can deliver both the requested output asset and destination gas. Your app can present the route as one guided flow while Socket handles route discovery, transaction construction, and status tracking.
