Single-chain swap

Effortlessly swap tokens within the same network directly on SubWallet in 1 click.

Supported swap pairs & swap providers

SubWallet supports single-chain token swaps on the following networks:

Network name	Swap provider	Supported swap pair
Hydration	Hydration	300+ swap pairs from 30+ tokens (DOT, GLMR, HDX, etc.)
Polkadot Asset Hub	Polkadot Asset Hub	DOT <> USDC DOT <> USDT USDC <> USDT
Ethereum	ChainFlip SimpleSwap* Uniswap* KyberSwap*	ETH <> USDC ETH <> USDT USDC <> USDT ETH <> FLIP USDC <> FLIP USDT <> FLIP WBTC <> ETH**
Arbitrum One	ChainFlip Uniswap	ETH <> USDC ETH <> USDT** ETH <> ARB** ETH <> WBTC**
13 EVM networks	Uniswap Labs Trading API	1000+ swap pairs across 13 networks
10+ EVM networks	KyberSwap	1000+ swap pairs across 10+ networks

(*): SimpleSwap doesn't support swap pairs involving the FLIP token.

(**): Available only for swapping via Uniswap Trading Labs API.

With single-chain swap, you can only swap tokens within the account you want to swap (i.e., tokens can't be swapped from one account to another).

Swap tokens via Hydration, Polkadot Asset Hub, ChainFlip, SimpleSwap & KyberSwap

Step 1: On the SubWallet homepage, select the "Swap" tab on the sidebar.

If this is the first time you click the button, the Terms of service popup will appear. Read carefully, then select "I understand the associated risk and will act under caution". After that, click "Confirm and continue swapping".

Step 2: On the Swap screen, enter the required information. This includes:

• The token you want to swap

• The token you wish to receive

• The amount of tokens to swap

In this example, we want to swap HDX for MYTH on the Hydration network.

If you're in the "All accounts" mode

In this case, you will need to select the swapping account.

1

Select the token you want to swap

Select "HDX (Hydration)" in this example.

2

Select the token you wish to receive

Select "MYTH (Hydration)" in this example.

Ensure the token you want to swap and the token you wish to receive are on the same network; otherwise, check out this guide.

If you want to change the slippage tolerance

To change the slippage tolerance, hit the button in the Slippage field.

A popup screen will appear on the right side. In the Slippage setting screen, select or enter your desired slippage tolerance and click "Apply".

You cannot change the slippage tolerance if the swap provider is ChainFlip or SimpleSwap:

• With ChainFlip, every swap has a fixed slippage tolerance of 2%.

• With SimpleSwap, the slippage tolerance can't be predicted as it varies based on market conditions, but it will never exceed 5%.

This feature is available for swap pairs on the Ethereum network.

To do that, hit the "<" button on the Quote rate field.
