Lightwallet

Background and general infos​

The most common wallet for DeFiChain, the so called light wallet is the app for mobile devices β€œDeFiChain Walletβ€œ. You find it on the google app store for Android or apples app store for iOs devices.

https://play.google.com/store/apps/details?id=com.defichain.app

https://apps.apple.com/app/defichain-wallet/id1572472820

The app is developed and actively maintained by Birthday Research – the R&D (Research and Development) arm of Cake DeFi https://birthday.dev/

The app gets updated frequently so always check if you are using the latest version.

As the name already tells you, it is a light wallet. So, it does not require a full node having the whole blockchain data downloaded. Instead, an API is used to connect to servers that provides this data – on the DeFiChain this is the so called ocean API. You can specify the endpoint you want to use in the setting as described in the article Lightwallet change Ocean

Everytime you want to do a transaction on the blockcahin (like for example sending or swapping coins) you will have to provide your passcode. While the transaction is processed you see an information pop up in the lower end of the app. There is also a link to open the transaction on defiscan.info. You have to wait until a transaction was finished to be able to sign the next one.

App Overview​

Here is a detailed user guide for the light wallet.

The interface of the Light Wallet consists of 4 major categories. You can switch between those categories with the buttons at the bottom of the app.

  • Portfolio
  • DEX
  • Loans
  • Auctions

Portfolio​

This is the main screen where you have an overview of the assets in your wallet.

Main screen - portfolio

  2. You can select the network (MainNet, TestNet or Playground) with the button on the top right. This button is visible on all tabs, so you always see at one glance if you are on the MainNet
  3. You can add multiple Adresses to you wallet. Each address will get a generated icon and it is possible to label each address. The labels can help to organize your addresses but are not shared on the blockchain and not visible to others. By clicking the icon or the label you get a pop up window where you can organize your addresses (add additional ones or rename them) and select the address you want to use in the wallet. The popup also lets you copy the addresses to the clipboard.
  4. With the Eye button you can toggle if the amounts and values of the assets are shown. For example, if you are using the wallet in public like on a train and some stranger sits beside you - you might want to hide the values.
  5. The total worth of assets in this address. By clicking you can choose the reference currency in which the total but also all other positions in the wallet are displayed. The available options are
    • BTC - Bitcoin
    • DUSD - The stablecoin on the DeFiChain
    • USDC – USD Coin, it is an ERC-20-Tokens issued by the Centre consortium
    • USDT – Tether, an ERC-20-Tokens issued by Tether Limited, when using Tether as reference currency the dollar sign is used in all amounts over the app
    • DFI – The native coin of the DeFiChain
  6. With the little arrow you can show or hide the details on how the total worth is calculated. This is especially helpful when you are using vaults as the details show how much is in the collateral (locked in vaults) and how much loans sum up as debit
  7. Send Button - forwards you to the send screen, described in detail bellow
  8. Receive Button - shows the current address on the DeFiChain, lets you copy this address in to the clipboard to be able to paste it in nother app. The address is also shown as a QR code that lets you scan the address with another devices camera.
  9. Swap Button- forwards you to the swap screen for trading one kind of token to another via the liquidity pools on the DEX, described in detail bellow
  10. Transactions - shows you the history of transactions of the current address on the blockchain. You can look up details for every transaction directly in the app or use a link to the transaction on defiscan.live
  11. Filter displayed Assets in the Portfolio. Available are the options
    • All tokens – show everything you got in the portfolio
    • dTokens – show DUSD and all stock tokens (like dTesla for Tesla or dMSTR for Microstrategy)
    • Crypto – show he dAssets representing crypto currencies like dBTC for Bitcoin or dETH for Etherium
    • LP tokens – show just the positions in liquidity mining pools (no matter if crypto or stocks) No matter which one of the 4 filters you choose, you will always see your DFI position on top.
  12. Here you can select the order in which the positions of the portfolio are listed. You can select ascending or descending by value (in the chosen reference currency mentioned in point 5), by amount of token or alphabetically.

Trading huge amounts is best split up in chunks and wait for the pool to rebalance between the separate transactions.
