Join us today! Get paid by "Remixed" blockchain smart contract xoxo

Are we rewarded based on merits at work?

Story: Our company is recently founded with three members. We are creating ethereum smart contract to democratize payment system, increase transparency and automate tax filing procedures.

Profits are distributed following a "trilogy" schedule as described below:

Level 1: equally among employees

Level 2: based on tiers

Level 3: how long members hanging with us

Kovan Transaction for Level-One Contract: EQUAL SPLIT

Note: CEO, CTO and Bob each get a third of 0.1 ETH, in other words, 0.0333 ETH based on the contract.

See Tiered Transaction on Kovan of 0.3 ETH from HR (click me)

Kovan Transaction Records

Ropsten Transaction for Level-Two Contract: Tiered Distribution

Note: CEO gets 60% of 0.15 ETH, i.e. 0.09 ETH; CTO gets 25% of 0.15 ETH, thus 0.0375 ETH; and Bob gets 15% of 0.15 ETH, or 0.0225 ETH.

Level-Three: VESTED SHARES

THANK YOU for Hanging with Us!

Goal: Distribute company shares for employees in a "deferred equity incentive plan" automatically.

DeferredEquityPlan

Deploy and Compile!

For a 100-day fastforward test contract: fakenow variable and fastforward function are created.

   /* @TODO: Test contract via fakenow variable
    uint fakenow = now;
    
       @TODO: Add this function to "fast forward" time by 100 days
    function fastforward() public {
    fakenow += 100 days;
}
*/

View Functions: Relaunch Ganache

The balance on HR Account decreased by 0.01 ether for gas fee on deployment.

Next Steps

To view transactions on Kovan EtherScan

Switch MetaMask from Localhost 8545 to Kovan and Ropsten Test Network

Option 1: Kovan or Ropsten Testnet

See screenshots at the beginning for confirmations

Need to fund HR account at the following address

HR: 0x8EaaBB9Fc753df2C50F0b01E99b4e0F1f2d970A6

Sample testcoin funding on Kovan

Then, follow the same process as on localhost:8545 to distribute to three different addresses for CEO, CTO and Bob.

Option 2 Coming up: Customized Ethereum Testnet

Again, need to run nodes to fund crypto account by connecting to customized network on MyCrypto Wallet.
