 When a user enters a dApp that supports x-chain accounts, the interaction and experience feel the same as with any Aptos wallet.
 The user connects with a x-chain account (e.g., Phantom for Solana) and can view their Derivable Abstracted Account (DAA) details, sign messages, and submit transactions to the Aptos chain.

+When a dapp submits a transaction using a x-chain account, the wallet adapter utilizes the `signIn` function (defined in the x-chain account standard) for domain verification and security. If a specific wallet does not support the `signIn` method, the adapter falls back to using the default `signMessage`. 
 The wallet is requested to sign a message to submit a transaction on the Aptos network. Once the wallet approves the transaction, it is submitted to the Aptos chain, where it undergoes a signature verification process.

 - `authenticationFunction`: This is a function that exists on-chain and is used to verify the signature of the x-chain account.
 - `accountIdentity`: This represents the identity of the account used in the on-chain authentication function to verify the signature of the x-chain account.
 In the Wallet Adapter, the `accountIdentity` is based on the original x-chain account's public key and the dApp domain (e.g., mydomain.com). The format is:
-`${originWallet.publicKey}${domain}`

    Since the account identity is based on the dApp domain, it is scoped to the dApp context. As a result, each account has a different DAA address on different dApps.

+The wallet adapter follows the [Solana Wallet Standard](https://github.com/wallet-standard/wallet-standard/blob/master/DESIGN.md) to discover wallets.
+Currently, the wallets that have been tested and support cross-chain accounts are:
+
+|          | Aptos Devnet | Aptos Testnet | Aptos Mainnet |
+|----------|--------------|---------------|---------------|
+| Phantom  | ✅           |                |

 Supporting x-chain accounts in a dApp requires only a 2-step installation process.

+
+### Install the `@aptos-labs/derived-wallet-solana` package

 Once you have installed the `@aptos-labs/derived-wallet-solana` package, you can import and use it.
 In the same file where you import the other wallets, such as `WalletProvider.tsx`, you can add the following:

 ### Considerations
 - Since the origin wallet creates an x-chain account and is most likely not integrated with Aptos, simulation is not available in the wallet.
-- Due to the use of the `signIn` standard available on other chains, wallets that have not implemented this flow are not supported.
 - While the x-chain account prioritizes DAA, each account also retains the origin wallet, so developers should be able to use it and interact with it
