How does Dfyn achieve gasless transactions?

Our partnership with Biconomy and integration of meta-transactions ensures that all transactions on the Dfyn network remain gasless for the Polygon network.

Step 1: User’s metamask is triggered for signature when performing a transaction on the Dfyn exchange.

Step 2: The signed data is relayed to Biconomy’s relayers.

Step 3: Biconomy’s relayers pay the gas fees and forward the transaction with user’s signed data to the Dfyn contracts.

Step 4: DFYN contracts decodes user information from signed data and updates the chain state.

To avoid bottlenecks, multiple Biconomy relayers work in parallel to relay different transactions.

To ensure that no malicious transaction takes place, only the relayers registered with Biconomy are permitted to participate in this process.
