Metamask: Do Account Abstraction Wallets on Different Chains Have Different Addresses?

The Metamask wallet, also known as Abstraction wallet, is a popular choice for users who want to manage their cryptocurrency accounts in a single wallet. Unlike traditional wallets that store your private keys and account addresses separately on each chain, Metamask wallets allow you to keep all your accounts in one place.

However, there is a common misconception among users: how do Account Abstraction wallets on different chains handle different addresses? In this article, we will take a deep dive into the behavior of Metamask wallets in terms of address management and explore why some users get different addresses on different chains.

What is Account Abstraction Walleting?

Account Abstraction Walleting is a technology that allows users to manage multiple cryptocurrency accounts in a single wallet. This approach allows you to store your private keys, account addresses, and transaction histories across different chains without having separate wallets for each chain.

Metamask is one of the most popular abstraction wallet solutions designed to work with Ethereum, Binance Smart Chain (BSC), Solana, and other blockchain platforms. Using Metamask on multiple chains allows users to manage their accounts in a single place, making it easier to track transactions across different chains.

Address Management Across Chains

When you use Metamask Wallet to abstract your account address across different chains, the following happens:

• Metamask stores all account addresses: Metamask Wallet stores the entire list of account addresses for each chain in its database.

• Addresses are linked to their respective accounts: Each account address is linked to the specific private key or Ethereum address associated with that account.

• Transactions across chains can still be made from the same account address

  

However, there is a potential problem: how does Metamask manage the transition between account addresses when transacting across different chains?

The problem with different addresses on different chains

When you make a transaction using your Metamask wallet, which abstracts multiple accounts across different chains, the following can happen:

• Different Ethereum accounts: If you have an Ethereum account and also a BSC or Solana account that you want to use for transactions, but they belong to different wallets, the Metamask wallet will automatically switch between the two accounts when transacting.

• Chain-specific addresses: The Metamask wallet can generate separate chain-specific addresses (e.g. 0x1234567890ABCDEF on Ethereum) even if you want to make a transaction across both chains.

Conclusion

In summary, account abstraction wallets like Metamask can store and manage multiple cryptocurrency accounts in a single wallet. However, transitioning between different address formats when transacting across different chains requires careful management. Here’s how to avoid issues with different addresses on different chains:

• Make sure you use the correct private key or Ethereum address for each chain.

• Use a clear and consistent naming convention for your account addresses (e.g. “0x1234567890ABCDEF”).

• Keep track of which accounts are linked to their respective chains.

By following these best practices, users can enjoy seamless transactions across multiple blockchain platforms using the Metamask wallet abstraction.
