# Comparing Two Addresses on a Chain

The same address can appear in different forms, such as different letter casing on EVM. Comparing raw strings misses those cases. Use `isSameAddress` to compare two addresses on a chain after the SDK normalizes both.

`isSameAddress` takes an `IsSameAddressOptions` object with `chain`, `left`, and `right`, and returns a boolean.

## Usage

> [tab] JavaScript
>
> ```javascript theme={"system"}
> import { isSameAddress } from '@dynamic-labs-sdk/client';
> import type { WalletAccount } from '@dynamic-labs-sdk/client';
>
> // walletAccount comes from your wallet accounts list (see getWalletAccounts).
> const isPayingWallet = (walletAccount: WalletAccount, address: string) =>
>   isSameAddress({ chain: walletAccount.chain, left: walletAccount.address, right: address });
> ```

> [tab] React
>
> `isSameAddress` is a pure helper, so there's no dedicated hook. Call it wherever you compare addresses:
>
> ```tsx theme={"system"}
> import { isSameAddress, type WalletAccount } from '@dynamic-labs-sdk/client';
> import { useGetWalletAccounts } from '@dynamic-labs-sdk/react-hooks';
> import { useMemo } from 'react';
>
> function useIsWalletAccount(address: string, chain: WalletAccount['chain']) {
>   const { data: walletAccounts = [] } = useGetWalletAccounts();
>
>   return useMemo(
>     () => walletAccounts.some((walletAccount) =>
>       isSameAddress({ chain, left: walletAccount.address, right: address }),
>     ),
>     [address, chain, walletAccounts],
>   );
> }
> ```
