Gas Station

Your users never worry
about gas again.

Sponsor transactions for your users with a custom policy. Define which contracts and wallets qualify, set spend limits, and let Zafeguard handle the rest — across all supported EVM chains.

How gas sponsorship works

01

User triggers action

User clicks "Mint" or "Transfer" in your app. Their wallet has zero ETH.

02

Policy check

Zafeguard checks if the action matches your sponsorship policy (contract, user, daily limit).

03

Gas is sponsored

If approved, Zafeguard covers the gas fee from your balance. The user's transaction goes through with no ETH required.

04

Transaction confirmed

The on-chain action completes. The user sees success. You see the cost in your dashboard.

Precise policy control

Not every user or action deserves sponsorship. Set policies that match your product logic exactly — no code required. Add rules in the dashboard, and they apply immediately across all chains.

Screen every address before you sponsor it

Before covering gas for a transaction, Zafeguard checks the sender's wallet against global sanctions lists and computes a risk score based on its on-chain history. High-risk or sanctioned addresses are blocked automatically — your sponsorship budget stays clean and compliant.

  • Automatic OFAC and EU sanctions screening on every request
  • Risk score 0–100 based on mixer exposure, dark-market links, and exchange risk
  • Set your own score threshold — block above 30, warn above 20, or customize per policy
  • Full screening log per transaction for compliance audits
  • Works alongside existing policy rules — both must pass before gas is sponsored
