Meta transactions are a mechanism used in blockchain networks to allow users to perform transactions without directly paying transaction fees in the network’s native cryptocurrency.
These transactions are facilitated by a third party, often called a relayer or meta transaction service provider. Users sign a transaction and send it to the relayer, who then broadcasts it to the blockchain on behalf of the user.
This approach is particularly beneficial for onboarding new users to blockchain applications by removing the need for users to hold the native cryptocurrency for transaction fees. It enhances user experience, making blockchain applications more accessible and user-friendly.
Additionally, meta transactions can help scale the network by potentially reducing congestion and allowing more efficient use of block space. However, they also introduce dependencies on the reliability and security of the third-party relayers, requiring careful consideration of trust and decentralization aspects.
