Crypto/Token Distribution Script
This Smart contract has been designed to allow for the distribution of polygon tokens (MATIC) to multiple wallets.
How it works
The contract needs to be compiled in an IDE, I use Remix (https://remix.ethereum.org/) Import the file tokenFundDistribution (or cut and paste the code).
For use on the Polygon TestNet (https://mumbai.polygonscan.com/) I compiled the smart contract using the compiler build v0.4.11+commit.68ef5810.
I did not enable optimization and left the number of runs at the default of 200.
The smart contract compiles with no errors.
Once compiled it needs to be pushed to the TestNet.
This is completed using the "Deploy and Run Transactions" tab within the ReMix IDE. The contract to be depolyed is called "RKPRIM - <yourfilename.sol>" I deployed it using Injected Web 3 (MetaMask). You'll need to add the Mumbai Polygon TestNet to MetaMask before deploying the smart contract. (https://docs.polygon.technology/docs/develop/metamask/config-polygon-on-metamask/)
Once deployed to the Mumbai TestNet the contract will need to be configured for distribution.
Step One:
verify the smart contract on the TestNet.
Step Two:
Now it's time so set up the distribution of the tokens based upon percentages. This smart contract uses the following logic 1% = 10.
For Example
If I wanted to send 15% to Wallet A, 25% to Wallet B and the remaining 60% to Wallet C, I would do the following;
Using the "write contract" tab, scroll down to "addAccount" Enter the public key of Wallet A in the _addr (address) field, 150 in the _pctx10 (uint256) field and finally "0" in the _evenStart (bool) filed.
Click "write", approve it using the same wallet you used to lock the smart contract and finally click on the "verfiy the transaction button" to confirm it's been successful.
This process can be repeated upto 5 times as this contract can only distribute to a maximum of five wallets.
Step Three:
Lock the smart contract to the same wallet that published it. This is done via the lock button/function on the smart contract "write" tab (This is a sub menu of the "Contract" tab). You will be asked to sign this transaction using MetaMask.
Step Four:
To Distribute, click the "write" button on the "write contract" tab within the distribute section. This will need to be approved using the wallet locked to the contract in step two.
Step Five:
Click on the "write" button within widthdraw section. This again will need to be approved using the wallet initially "locked" to the smart contract and viola. The distribution of proceeds will take place.

When checking the token recipients wallet for funds - check "Internal Txns". This process is often known as "Token Fund Flow". This smart contract will also work for this providing the token fund flow has five or less total recipients.
