Optimized Token Swapping with Fibrous

Fibrous allows you to swap tokens and offers various settings to provide the best trade options for you. By scanning the prominent liquidity sources on the network you are using, it creates a complex trade pathway for you and delivers favorable rates in the simplest way.

​
Benefits of Using Fibrous

  • Price Optimization: Fibrous isn’t just an exchange; it’s an aggregator. This means it looks across multiple exchanges to get you the best price.
  • Gas Fee Savings: Compared to other platforms, Fibrous often results in lower gas fees.
In conclusion, while platforms like Uniswap are direct exchanges, Fibrous ensures that you get the best deal across multiple exchanges, often saving you on fees and getting you a better swap rate.

Step 4: Approve or Permit Contract to Swap Tokens

Approve or permit Fibrous to swap the tokens on your behalf. Proceed to Step 5 if token approval/permit is not required. Thanks to Starknet’s Native Account Abstraction! You do not need to approve separately for your swaps. If this is your first time swapping token on Scroll network with Fibrous using your wallet, you’ll find that the Swap button is grayed out. You’ll need to approve the Fibrous smart contract to spend your tokens before you can proceed with the swap.
Token Approval Interface

To help our users save on gas fees, Fibrous offers a Permit based approval option for tokens that adhere to the ERC-2612 standard. Unlike the basic ERC20 token implementation, ERC-2612 allows for gasless approvals of smart contract allowances through a simple signed message. In other words, approving a token via Approve doesn’t require any gas and has the same effect as the ERC20 Approve.
To ensure the security of your tokens, you’ll be prompted to sign the transaction for the exact amount in your wallet’s interface. By signing the approval request, you’re ensuring that Fibrous can only swap the exact number of tokens specified from your wallet. If future swaps exceed this amount, you’ll need to complete the approval process again.

Step 5: Confirm the Swap

After everything is set up, you can click on the Swap button. In the tab that appears, you can adjust the slippage settings and see the amount you will receive in the event of negative slippage. Once everything is in order, you can initiate your transaction by clicking the Confirm button.

Customizing Slippage Tolerance

Slippage is the potential price difference from when you initiate a trade to when it’s processed on the blockchain. ‘Auto’ is set at 1.0%, meaning the final price could vary by half a percent from the quoted price. You can adjust this according to your risk tolerance. Apart from the options of 0.1%, 0.5%, and 1%, you can also set a custom slippage.

Find Your Favorite Tokens

To make it easy for you to swap any two tokens at the best rates on the Fibrous interface, we have developed token categorization. In this categorization:

Token List on app.fibrous.finance

  • All: Displays all tokens with a specific ticker on the selected network.
  • Verified: This category includes a selection of tokens that are widely used and generally considered reliable for trading. If you want your token to be verified on Fibrous, you can check the repository below. https://github.com/Fibrous-Finance/Fibrous-tokens
  • Stable: Offers a selection of all available stablecoins.
  • Meme: Showcases meme tokens that are prominent on your network and have surpassed a certain volume threshold.
  • Unrugged (for Starknet): This selection displays all tokens originating from the Unruggable.meme platform, which allows the deployment of unruggable tokens on Starknet.

​
Managing Liquidity Sources

Fibrous will automatically select the best sources on the selected network. You can choose the liquidity sources you want to use from this tab according to your preference. By default, all Fibrous supported DEXes on the connected chain will be selected. You can view the list of supported DEXs on each chain by the Swap Settings tab.
If you do not select all liquidity sources, you may not achieve the best price fetching. To maximize your swap outputs and trade with the widest variety of token variations, you should keep all liquidity sources enabled.
