We are delighted to announce that Dfyn has integrated Router’s widget into its platform. This integration effectively makes Dfyn a cross-chain DEX. You can now use Dfyn as an entry and exit point to and from other chains and trade across multiple chains directly from Dfyn’s UI.

After a period of ideation, iteration, and due diligence, we released the Roadmap for Dfyn v2 on April 26th.

A key milestone on the roadmap has always been making Dfyn a truly cross-agnostic DEX. Router widget integration makes this possible and opens up accessibility for users outside Polygon and Fantom. Users on Ethereum, BSC, Arbitrum, Fantom, Polygon, Optimism, and Avalanche, and soon the users on Cronos, Harmony, and Aurora, can now instantly and securely execute cross-chain swaps/transfers on Dfyn.

Here is a quick step-by-step tutorial on how to conduct cross-chain swap/transfer using the Router widget on Dfyn:

Step 1: Navigate to https://exchange.dfyn.network/#/crosschainswap

Step 2: Select the source and the destination chain.

The source chain is the chain you currently have funds on. You will also need to make sure your MetaMask wallet is set to this network. The destination chain is the chain you would like to move funds to. In this case, our source chain is Avalanche, and the destination chain is Polygon.

Step 3: Select fee token.

A unique feature of Router Widget is that it lets users choose which token they would like to use to pay the transaction fees. Current options are USDC, DFYN, ROUTE, and the chain’s native gas token (AVAX on Avalanche, MATIC on Polygon, etc.).

Important notes:

  • As an added incentive for our community, users will receive a 50% discount on fees paid in $ROUTE tokens and a 20% discount on fees paid in $DFYN tokens.
  • Ensure that you have a sufficient amount of the chosen fee token in your wallet to pay for the transaction fees. By default, the “Fee Token” will be set to the source chain’s native gas token.

Step 4: Select the asset you wish to bridge from Avalanche to Polygon. In this case, we will be trading AVAX on Avalanche for MATIC on Polygon.

Step 5: Enter the number of tokens you wish to transfer.

Step 6: Once the pathfinder is done estimating the number of tokens to be received on the destination chain, click on “Swap”.

Step 7: After approving the tokens successfully, you will be asked to confirm the swap. Once you approve it, your job is done. Router Protocol’s swapping engine will now conduct your cross-chain swap.

Step 8: Just to be safe, you should always confirm the status of the transaction from your wallet once you get the acknowledgment that the swap is complete on Dfyn.

The integration of the Router widget is one of our many upcoming developments to add comprehensive cross-chain capabilities on Dfyn. Join our community to be the first to know about our new updates.
