User Guide for TestNet Swap


A test swap powered by Uniswap V2 contracts has been deployed on Core TestNet for users to experience decentralized trading. Please visit
Note that all tokens added to the test swap are only used for testing. They don’t have any value. Please do not use them for real transactions.

Connect wallet and load token list

Before you use the test swap, make sure you switch to Core TestNet on your wallet. Click the Connect to a wallet on the top right corner to connect to wallet.
The first time you use the test swap, you need to choose a token list. There is a built in Core token list, or you can load your own token list. The built in token list contains fake USDT (sUSDT) for testing. Again, all tokens added to the test swap do not contain any value at all, please do not use them for real transactions.

Fetch sUSDT from faucet

You can fetch sUSDT from the faucet website. Visit, fill in your address to get 100-200 sUSDT. One address can only fetch sUSDT once from the faucet each day. If you are using Metamask chrome wallet, you can also click the Add sUSDT to Metamask button to add this test token to the wallet directly. sUSDT is only used for testing and is without any value, please do not use it for real transactions.

Add/Remove Liquidity

Click pool and choose token pairs you want to add liquidity. Make sure you have enough tokens on both sides. After you successfully add liquidity, you will receive the LP tokens which represent your share in the pool.
You can also remove the liquidity on the pool page. Select the LP token under Your Liquidity and choose the amount of the LP token you want to remove. After you successfully remove liquidity, you will receive the underlying pair of tokens.


Click swap and choose the token pairs you want to swap. Input the amount of the source token you want to swap out and the website will calculate the estimated amount of the target token you will receive (or vice versa). After you successfully swap the tokens, you can check out the changes in your wallet.
