How do I swap tokens on DeFi Swap?

You can swap between any two supported tokens upon paying a 0.3% swap fee;

  • Direct conversion if there is a liquidity pool for the exact same pair and it offers the best price;

  • Routes trades across several liquidity pools if otherwise (e.g. LINK to ETH and ETH to USDT for LINK to USDT conversion, if there is no liquidity pool for LINK to USDT or if a direct conversion from LINK to USDT incurs a higher price);

To start swapping tokens:

  1. Connect your decentralized wallet to DeFi Swap

  2. Go to the [Swap] tab

  3. Select the corresponding input and output token from the supported token list

  4. Click [Swap]

  5. Review the input/output token values, price, minimum received (due to slippage), price impact, and liquidity provider fee (swap fee)

  6. Click [Confirm Swap]

  7. Confirm the transaction on your connected wallet

You will then see the transaction is submitted and you can follow the confirmation status by clicking [View on Etherscan].

Why did my swap transaction fail?

Occasionally, your swap transaction might fail due to the “Insufficient Output Amount” Error. Your input tokens will be reverted but the network fee (gas) will be spent.

This is likely due to a sudden hike in swap volume for the corresponding token pairs, to increase the chance of your swap transaction going through and is confirmed during the peak trade period, you may either -

  • Adjust to a higher gas fee so miners are more likely to confirm your transaction first

  • Adjust to a higher slippage tolerance % via Settings > Transaction Settings

How are swap prices determined?

DeFi Swap follows a constant product formula, where the product of the quantities of two tokens remain the same before and after a swap is performed.

The smart contract maintains a constant using the following function: x*y=k. In this case x = Token A, y = Token B, k = constant.

For each trade, a certain amount of tokens are removed from the pool for an amount of the other token. To maintain k, the balances held by the smart contract are adjusted during the execution of the trade, therefore changing the price whenever someone makes a trade.

Price slippage depends on the ratio and quantity of tokens in the pool.
