Swap

On-Chain Swaps

The Crust Swap Engine intelligently combines multiple liquidity pathways to provide the most efficient trading experience. It utilizes Crust’s classic and concentrated liquidity pools while occasionally incorporating external sources to enhance price execution.

  • Classic Liquidity Swap: Modelled after the UniV2 design, Classic liquidity swaps source liquidity from evenly distributed pools. This approach is straightforward and ideal for traders seeking simplicity and stable swaps, with no need to set price ranges manually.

  • Concentrated Liquidity Swap: Concentrated liquidity focuses liquidity within specific price ranges, maximizing capital efficiency. This results in tighter spreads, reduced slippage, and better pricing, particularly for larger trades.

In summary, the Swap Engine is designed to offer flexibility, efficiency, and optimal pricing for all trading needs.

Breaking Down the Platform

In terms of set-up, there are only two things to do:

  1. First, navigate to the swap tab in the top bar.

  2. Ensure your wallet is connected and that you are on the Monad mainnet.

  1. Swap Tab: Toggle between on-chain and cross-chain swaps.

  2. Customise Settings: Customise swap settings. Refer below for details on settings.

  3. Token List: The top token is the sell token; this is what you're swapping out of. The bottom token is the buy token; this is what you're swapping into. You can click to open the token switcher pop-up to select a different token.

  4. Amount Input: Enter the amount of tokens you want to swap. The top one is for you to enter. The bottom shows up as the quote.

  5. Slippage Tolerance: Your current slippage tolerance. Refer below for details on slippage.

  6. Price: This value is the amount of token 1 you need for a single token 2. The amount of token 1 that you're swapping divided by this number will give you the amount of token 2 you will be receiving.

  7. Minimum Received: The minimum received value is the floor for how little you can receive from a swap. Factors such as price impact and slippage can affect this. Typically, it is a negligible loss, but if you have extremely high slippage, it can be quite a large loss.

  8. Route Chart: The route shows you how your money will be moving. In this example, I am swapping $USDC to $USDT, just as displayed.

    1. Legacy: The route goes through Classic Liquidity.

      1. Stable: Uses a stable pool.

      2. Volatile: Uses the volatile pool.

    2. CL: The route goes through Concentrated Liquidity.

    3. Price Impact: In simple terms, this is how much your swap can vary. In more complex terms, this value is the amount that your swap changes the balance of the liquidity pool, ultimately affecting the price and changing your final swap output.

  1. Slippage: Slippage is basically the difference between the expected price of a trade and the actual price paid due to changes in the market conditions during the time it takes for the trade to be executed.

    The higher you set the slippage percentage, the more it potentially allows for less of the Swap-In asset to be allowed. As a safe measure until a user becomes more acquainted with DeFi, it is always recommended to have slippage set below 1%.

  2. Transaction Deadline:  Your transaction will revert if it is left confirming for longer than this time.
