Current Functionality:

Setup

Download one of the compiled releases in the Releases section and unzip it into a location of your choice. You will need to edit the included appsettings.json file with your own Loopring details.

Here is a video going over the setup: https://youtu.be/P0EvuxfpCR4

This application uses a MetaMask/GameStop private key to sign the transfers. You will need to export that out from your metamask/gamestop Wallet. You can export the Loopring related account details from the "Security" tab while logged into https://loopring.io. Make sure these details are from the same Wallet. Note that you cannot perform transfers with a Loopring wallet

macOS users: You also need to run the following command in the unzipped folder of LoopDropSharp to turn it into an executable in order to run it. You may also need to add it as a trusted application if it get's blocked from running (Settings > Security & Privacy).

chmod +x LoopDropSharp
If compiling yourself please read the section about it below.

DO NOT SHARE ANY API OR PRIVATE KEYS with anyone else!!!!!!!

You will need to change the "appsettings.json" file in the project directory with the necessary information. The video above covers this.

{
  "Settings": {
    "LoopringApiKey": "ksdBlahblah", //Your loopring api key.  DO NOT SHARE THIS AT ALL.
    "LoopringPrivateKey": "0xblahblah", //Your loopring private key.  DO NOT SHARE THIS AT ALL.
    "MMorGMEPrivateKey": "asadasdBLahBlah", //Private key from metamask. DO NOT SHARE THIS AT ALL.
    "LoopringAddress": "0xblahabla", //Your loopring address
    "LoopringAccountId": 40940, //Your loopring account id
    "ValidUntil": 1700000000, //How long this transfer should be valid for. Shouldn't have to change this value
    "MaxFeeTokenId": 1, //The token id for the fee. 0 for ETH, 1 for LRC
    "Exchange": "0x0BABA1Ad5bE3a5C0a66E7ac838a129Bf948f1eA4" //Loopring Exchange address
  }
}

After setting up the appsettings.json, launch LoopDropSharp and get started.

Credits

The original boiler plate was originally made by Fudgey, then I did some modifications. It was then time for LoopDropSharp to be created.

Also thanks to: ItsMonty.eth for the original NFT Transfer code in the LooPyMinty repo which I converted to C#. Also, thanks to Taranasus for his LoopringSharp repo for the ECDSA signing which I also used. Fudgey's PoseidonSharp library was used for generating the Poseidon hashes and EDDSA signing.
