# Asset Hub Migration FAQ ### What is Relay Chain? What is Asset Hub? You probably know the **Kusama Relay Chain** as just **Kusama**, and the **Polkadot Relay Chain** as just **Polkadot**. Relay Chain is the "main" chain. It secures all the parachains in its ecosystem and processes cross-chain transfers between them. Relay Chain only supports its native token: KSM on Kusama Relay Chain and DOT on Polkadot Relay Chain. Before migration, most operations with KSM and DOT happened on their Relay Chains. **Asset Hub** is a **system parachain** that supports **other tokens** in addition to KSM and DOT. You can think of it as an **extension of Relay Chain** that allows its users to create and manage other assets: stablecoins, memecoins, tokens from other chains in the Polkadot ecosystem, NFTs, etc. Each Relay Chain has its own system parachain: there's **Kusama Asset Hub** connected to Kusama Relay Chain and **Polkadot Asset Hub** connected to Polkadot Relay Chain. Before migration, Asset Hubs were mostly used for operations with tokens beyond KSM and DOT. ### What Is Going to Change? Starting from **October 7th**, your **KSM** balances, governance, and staking **migrate** from **Kusama** **Relay Chain** to **Kusama Asset Hub**. On **November 4th**, a similar migration will happen for **DOT** from the **Polkadot Relay Chain** to **Polkadot Asset Hub**. Relay Chains will focus on securing chains, while Asset Hubs will take care of day-to-day operations: balance transfers, governance votes, delegations, and staking. Here are the key changes: * Your **KSM/DOT** **balances** will be moved to **Asset Hub**. Your other token balances on Asset Hub will not be affected. Migrated balance will be added to any KSM/DOT you might've had on Asset Hub before migration. * The **minimum KSM/DOT balance** your account needs to maintain will become **100 times lower**: from 0.00033 KSM to 0.0000033 KSM and from 1 DOT to 0.01 DOT. * Any **transfers** you would usually make on Relay Chain will now happen on **Asset Hub**. Your **addresses** will remain **the** **same** as before the migration. * Your **transaction fees** and **deposits** (e.g., for multisig operations) will become **10 times lower**, and you will be able to pay them **in any token**. * Your **staking** setup and rewards will now be on **Asset Hub**. All your staking information will be migrated automatically. The staking UI will remain the same: you will be able to do all the same things as before the same way. Your **staking rewards** will **not be interrupted**. * Your **governance** votes and delegations will now be on **Asset Hub**. Your past votes and delegations will be migrated automatically. The governance UI will remain the same: you will be able to do all the same things as before the same way. * Your **crowdloaned** KSM/DOT will be migrated **later**, after your candidate's slot lease ends and your tokens are returned to you. * Your **multisigs** and **proxies** will be **recreated** on **Asset Hub**. You will still be able to use them on Relay Chain if needed, but most operations will take place on Asset Hub. **Ongoing** **multisig transactions** will **not be migrated**, and you may want to finalize or cancel them on the Relay Chain **before the migration**. * If you are a **validator**, you can keep validating blocks as before. You will **register your session keys** on the **Relay Chain** as before, and other staking-related actions will happen on Asset Hub. * **Fast-unstake** will be **deprecated** after staking migrates to Asset Hub. This feature was only available to users who had **inactive stakes** for more than 7 days on the Kusama Relay Chain or 28 days on thePolkadot Relay Chain. It was never supported in Nova Wallet natively. ### What Do I Need to Do Before the Migration? **Nothing**! Your tokens in Nova Wallet will be migrated **automatically**; **no action needed**. ### What Will Happen During the Migration? {% hint style="success" %} Your funds are safe during the migration process. {% endhint %} The migration period is estimated to last **8 to 10 hours**. During the migration period, you may experience some interruptions: * Your KSM/DOT **balances** may take **longer** than usual to **be updated**. **Your funds are safe!** No tokens will be lost; your balances will be updated after the migration ends. * **Cross-chain transfers** to or from the Relay Chain and Asset Hub will be **paused** until the migration ends. **Regular transfers** within Asset Hub will **not be affected**. * Some operations on the Relay Chain will be **paused**: governance, multisig operations, proxy operations, and others. They will resume on Asset Hub after the migration ends. * Some **centralized exchanges** may experience **delays** with processing KSM/DOT deposits and withdrawals during the migration period. ### What Do I Need to Do After the Migration? If you receive KSM/DOT on Relay Chain after the migration, **send** them **manually** to your own wallet on **Asset Hub**: [send-tokens-cross-chain](https://docs.novawallet.io/nova-wallet-wiki/asset-management/how-to-send-tokens/send-tokens-cross-chain "mention"). Tokens sent on the wrong chain post-migration **will NOT be lost**. Your staking rewards and governance votes before and after migration will be shown together in Nova Wallet. **You won't miss any staking or governance data** in Nova Wallet. Your transfers and other operation history will be shown separately: [view-operation-history](https://docs.novawallet.io/nova-wallet-wiki/asset-management/view-operation-history "mention"). To view your **pre-migration history**, check your Operation history on the **Relay Chain**. Your **post-migration** history will be on **Asset Hub**.
