This is easier than you think. Just connect your wallet in the highlighted green option in the upper right screen corner inside DSWAP. Supported wallets are Metamask, WalletConnect, Coinbase wallet or Fortmatic and we're working on full compatibility with the SuperApp.
When we said that DSWAP layout is identical to Uniswap open-source one we mean it.
Now connected you can do swaps on five networks: Ethereum, Binance Chain, Polygon, Avalanche and Fantom. (Note that DSWAP was deployed only for Ethereum blockchain and now works perfectly in the other ones mentioned).
