How to mint NFTs and run in-game actions without users paying gas

Mint and games: the user gets stuck on gas

A player wants to claim an item. A collector wants to mint an NFT. A loyalty user wants to redeem an on-chain reward. All hit the same wall: they need the network's native coin to pay gas — and most don't have it, nor know what it is. That's where conversion dies.

The fix: you pay the gas for them

With VKX Gas, you sponsor the transaction. The user mints, claims or redeems gasless, with the wallet they already use (via EIP-7702, no migration). You're charged only for the real gas, from your prepaid balance.

Steps to integrate

• Install: npm install @vkx/gas
• At the mint/claim moment, build the user's operation and call prepare.
• The user signs, you submit. Done — a gasless transaction.

Why it makes sense for games and NFTs

• On BNB Chain, Polygon, Base and Arbitrum gas costs pennies: sponsoring is cheap next to the value of converting a user.
• VKX's cashback becomes credit that subsidizes the next mints — your per-transaction cost drops with usage.
• A single deposit covers all EVM chains, so you don't manage balance chain by chain.

Example use cases

• GameFi: reward and item claims without the player holding gas.
• NFT/mint: gasless mint campaigns for a non-crypto-native audience.
• Loyalty: on-chain point redemption with no friction.
