Gasless Transactions
Gasless Transactions, also known as meta-transactions, are transactions that have the gas fee paid for by a third party instead of the transaction sender. Typically, this means the dApp owner covers the gas costs of their users' transactions, providing a more seamless user experience.
This works by having the user sign a message that is then sent to a relayer, which pays the gas fee and forwards the transaction to the blockchain.
Our SDK integrates seamlessly with Biconomy and OpenZeppelin Defender, two popular gasless transaction providers; allowing you to cover the gas fees for your users' transactions.
- Biconomy: Best if you want to cover the gas fees for one kind of transaction (e.g. minting NFTs).
- OpenZeppelin Defender: Best if you want to cover the gas fees for all kinds of transactions.
View our step-by-step guides below to learn how to integrate gasless transactions into your dApp using the SDK.
