# Migration

### New SDK Version

```
npm install @leapwallet/embedded-wallet-sdk-react@latest
```

### From v0 to v1

1. **Aggregated View:** This view allows dApp to choose multiple chains for which they can show aggregated balances.
2. **Addresses View:** Address page allows user to view and copy addresses of chains for which balances are being showed.
3. **Action Button Customization:** Providing more flexible action button usage by allowing to optionally hide them and change their ordering.
4. **Scan for more discoverable chains:** When using chains which share coin-types with others chains which you might not have passed a record for, they will automatically be discovered and will be used in fetching balances. You can disable this by enabling `restrictChains` as false.

Now you can pass addresses and REST URLs of chains as follows:

```
<AccountModal
  theme="dark"
  chainRecords={chainData}
  isOpen={isModalOpen}
  onClose={closeModal}
/>
```

where `chainData` is a record of address and REST URL, having chain-id as their keys.

### From v1 to v2

1. **Wallet Connection:** Allows dApp to pass their wallet connection management hooks in order to control wallet connection from embedded wallet.
2. **Fetching balances from connected account:** Instead of passing chain records, balances can be fetched using the connected chains via wallet connection itself. dApp can optionally pass a list of chain-ids to restrict balance fetching to only those chains.

All exported components like AccountModal and AccountView need to be enclosed by EmbeddedWalletProvider.
