Sign In With X

​
Introduction

The Sign In With X feature enables decentralized applications (Dapps) to authenticate users seamlessly across multiple blockchain networks, such as Ethereum, Polygon or Solana. This feature allows developers using our SDK to implement authentication by having users sign a unique string message with their blockchain wallets. The Sign In With X feature is designed in accordance with the CAIP-122 standard, which establishes a chain-agnostic framework for blockchain-based authentication and authorization on off-chain services.

Getting Started

SIWX works as a plugin system for AppKit and you are going to add the plugin in the AppKit configuration. There are some ways to implement the SIWX feature:

  • Use Reown Authentication to manage the sessions in the Cloud Dashboard
  • Use the DefaultSIWX class provided by AppKit
  • Create a custom implementation to suit your specific requirements.

To initialize the SIWX feature, you need to add the siwx parameter to the createAppKit function.

​
Reown Authentication

Reown Authentication is a predefined implementation of the SIWX configuration plugin that uses the Cloud service to create and manage SIWX messages and sessions. With Reown Authentication, you will be able to see and control the sessions of your users using the Reown Dashboard.

Read more about the Reown Authentication Implementation.

​
Custom Implementation

DefaultSIWX is a scaffold implementation of the SIWX feature for quick custom integration. It offers pre-built components to get the feature running quickly with some custom adjustments. Additionally, the expected ` parameters can be configured to allow customization of the feature to suit your specific requirements.

The defined interface must follow specific rules to make sure that AppKit can interact with it correctly. Read more about how to have your Custom Implementation.

​
SIWX Expected Behavior

  • SIWX will prompt to get the user signature and verify his identity every time a connection happen;
  • In case a SIWX session is already stored, the user will be automatically signed in and the prompt step will be skipped;
  • If the user changes the connected network, SIWX will prompt to get the user signature and verify his identity again;
  • If the user disconnects from the Dapp, SIWX will revoke the session and the user will need to sign in again.

​
Migrating from SIWE to SIWX

If you are currently already using SIWE from @reown/appkit-siwe, after AppKit version 1.5.0, you will be migrated into SIWX. The migration process is automatic and your siweConfig from createAppKit function will be mapped internally.

It is important to note that if you cannot use siweConfig and siwx at the same time, createAppKit will throw an error in case this happens.

You may replace siweConfig with your own siwx configuration manually if you would like to do so.
