How to offer gasless transactions to your users
Let your users transact without holding the native coin. You sponsor the gas via EIP-7702, with cashback and a single deposit for all EVM chains.
How to offer gasless transactions to your users
The biggest friction for a non-crypto-native Web3 user is gas: to do anything on-chain, they need the network's native coin (BNB, POL, ETH...). That blocks NFT mints, in-game claims, stablecoin payments. The fix is to sponsor the gas — and that's what VKX Gas does as a service.
How it works (prepaid model)
- You deposit native coin into the VKX treasury. One deposit serves all EVM chains.
- Your user transacts gasless; VKX pays and charges your balance.
- It runs on EIP-7702: the user does not switch wallets, their own account delegates. No migration.
In code
- Install: npm install @vkx/gas
- Build your user's operation and call prepare with the network and the operation.
- VKX returns the signed sponsorship; your user signs and you submit. The charge comes off your balance based on the transaction's real gas.
Cashback: your balance works back for you
Part of what you pay comes back as cashback — a credit that is non-withdrawable but used first on the next transactions. So the more you use it, the more future transactions get subsidized. Unlike providers that only charge, here part returns to you.
Pricing (markup on real gas, per chain)
- BNB Chain and Polygon: 105% markup, with a 4.76% cashback tag.
- Base and Arbitrum: 65% markup, with a 7.69% cashback tag.
- Ethereum: 20% markup, with a 1.25% cashback tag.
On cheap chains (BNB, Polygon, Base, Arbitrum) the absolute per-transaction cost is pennies — what you gain is the conversion of users who today give up at "you need gas".
Who it's for
Games and GameFi, NFT/mint projects, fintechs, dApps and loyalty programs — any product whose users are not crypto-native.
