# Migration guide from v7.2 to v7.3 for Embedded Wallets Android SDK

## Overview[​](#overview "Direct link to Overview")

This migration guide provides steps for upgrading from version 7.2(v7.2) to version 7.3(v7.3) of the Embedded Wallets Android SDK. The guide outlines significant changes in the `request` method.

## Changes in detail[​](#changes-in-detail "Direct link to Changes in detail")

### `request` method updates[​](#request-method-updates "Direct link to request-method-updates")

From v7.2, `loginParams` is removed from the `request` method. To further improve developer experience, developers can now pass the `chainConfig` to request signature for specific chain.

#### Before (v7.2)[​](#before-v72 "Direct link to Before (v7.2)")

Usage

```
val params = JsonArray().apply {
    add("Hello, World!")
    add("<User's Hex address>")
    add("Android")
}

val signMsgCompletableFuture = web3Auth.request(
    loginParams = LoginParams(
        selectedLoginProvider,
        extraLoginOptions = null,
        mfaLevel = MFALevel.NONE,
    ),
    "personal_sign",
    requestParams = params
)

signMsgCompletableFuture.whenComplete { _, error ->
    if (error == null) {
        Log.d("MainActivity_Web3Auth", "Message signed successfully")
    } else {
        Log.d("MainActivity_Web3Auth", error.message ?: "Something went wrong")
    }
}

```

#### After (v7.3)[​](#after-v73 "Direct link to After (v7.3)")

Usage

```
val params = JsonArray().apply {
    add("Hello, World!")
    add("<User's Hex address>")
    add("Android")
}

val signMsgCompletableFuture = web3Auth.request(
     chainConfig = ChainConfig(
        chainId = "0x1",
        rpcTarget = "https://mainnet.infura.io/v3/$key",
    ),
    "personal_sign",
    requestParams = params
)

signMsgCompletableFuture.whenComplete { _, error ->
    if (error == null) {
        Log.d("MainActivity_Web3Auth", "Message signed successfully")
    } else {
        Log.d("MainActivity_Web3Auth", error.message ?: "Something went wrong")
    }
}
