There are many blockchains and Layer 2 scaling solutions to choose from on 1inch Network. Each has their own characteristics - anywhere from cheaper fees to faster transaction speeds, to even a larger selection of liquidity sources.

Gnosis

Klaytn

Optimistic Ethereum

Polygon
​zkSync Era

​RabbitHole (Ethereum) (For Metamask only)

***Please note: All 1inch protocols (Aggregation, Liquidity, Limit Order, and Governance) may not be available on all networks. Currently, only Ethereum Mainnet and BNB Chain can be used with all 1inch protocols.

In order to operate on any of the networks above, both the connected wallet and the 1inch dApp must be switched to the same network.

Switching networks on the 1inch dApp:

To switch networks on the dApp, simply click the toggle button at the top of the page, OR select the network you would like to use when connecting your wallet:

Switching networks in your wallet:

If you are using the 1inch iOS wallet, tap the the button at the top and select the desired network, as outlined in this guide.

For other non-1inch wallets, you will need to configure the network's custom RPC. (This example is with Metamask wallet)

First click on the network menu at the top of the wallet.

If the network you want to use isn't already configured, click "Custom RPC" at the bottom of the next menu.

Here you will be able to enter all of the required information to add the network to your wallet.

Once your wallet is configured, you are ready to start using 1inch on a different network! If you have any existing assets on a previously existing blockchain, you can convert them over to this newly added one by using a token bridge. Please see this guide for more details on the process.
