Gasless Transaction
A gasless transaction is a transaction flow where the user does not pay network gas directly from their own wallet.
What is Gasless Transaction?
A gasless transaction allows users to interact with a blockchain without holding or paying the network's native token for fees. Instead, a third partysuch as an application developer or a "paymaster"covers the gas cost to improve the user experience.
How does Gasless Transaction work?
- The user signs a digital message authorizing a specific action.
- This message is sent to a "relayer" or "bundler" rather than directly to the network.
- The relayer wraps the request into a standard on-chain transaction.
- The relayer or a designated sponsor pays the required gas fee.
- The transaction is executed on-chain as if the user had paid for it.
Why does Gasless Transaction matter?
Gasless transactions remove a major barrier to Web3 adoption by allowing new users to interact with apps immediately without first buying cryptocurrency. They enable "freemium" models in decentralized games and social platforms.
Key features of Gasless Transaction
- Sponsored fee coverage
- Improved user onboarding
- Relies on relayers or account abstraction
- Uses meta-transactions or
ERC-4337 - Removes the need for native gas tokens
Examples of Gasless Transaction
A Web3 game might sponsor the "minting" fee for a new player's first item, or a smart contract wallet might allow users to pay fees using stablecoins instead of the native network token.
