The Atomic Bridging and the Biconomy Relay

The idea of how L2 works with Scaleswap is pretty straightforward: when a customer decides to swap, this customer signs an L1 smart contract via MetaMask [Choi] to trade layer 1 Ethereum into L2 tokens, called “wrapped Ethereum” in the L2 jargon. The L1 ETH thus becomes “locked”, until the L2 smart contract instructs otherwise. The L2 smart contracts competenciesous L2 operations (swapping, exchanging, etc.) for the customer. If the customer decides to withdraw, back to conventional L1 ETH — L2 smart contract unlocks the corresponding amount on L1 via atomic bridging.

The most crucial takeout from the figure above (which we consider our point of innovation) is that Scaleswap’s customers don’t have to change their RPC (remote procedure call) destination from Ethereum to Polygon in their Metamask. This should offer a huge relief to those doing day-to-day swaps and trading DeFi tokens.
