Paymaster support for Starknet

Help - Plug n Play
1

Hello, the process I go through right now for using web3auth with Starknet, requires funding the account first, which is a bit inconveniencing for my target users. Does web3auth support or intend to support paymasters like AVNU to make this process easier?

Thank you for your question, Stephanie!

Summary for Support Team:

  • SDK/Platform: Plug n Play (likely Web3Auth Plug and Play SDK, platform not specified)
  • Issue Type: Feature request / integration inquiry
  • Blockchain: Starknet
  • Request: User would like to know if Web3Auth currently supports, or plans to support, paymasters (e.g., AVNU) to enable gasless transactions for users on Starknet, thereby removing the need for users to fund accounts before usage.

Response:

At this time, Web3Auth does not natively support paymasters or account abstraction flows (such as those provided by AVNU) for Starknet out-of-the-box. Your use case—enabling gasless onboarding for users—is a common request, especially for improving user experience in Starknet dApps.

Current Status:

  • Web3Auth primarily handles authentication and wallet key management.
  • Paymaster and gas abstraction features are typically managed at the smart contract or wallet orchestration level, not directly within Web3Auth.

What you can do:

  • You can integrate a paymaster solution like AVNU at the application layer, after user authentication via Web3Auth. This means, after the user is authenticated and their wallet is created, you can programmatically sponsor transactions using a paymaster service.
  • For more on Starknet integration, see: Web3Auth Starknet Integration Guide

Feature Request:

  • Your feedback is valuable! I’ll flag this as a feature request for native paymaster support with Starknet in Web3Auth Plug n Play SDKs.
