Smart Contract Payroll

Payroll Smart Contract with Truffle and Zeppelin Solidity. It allows an owner to manage employees. Employees can request payment in tokens for given pay periods.

Install

Clone repo:

git clone git@github.com:NFhbar/Ethereum-Payroll.git

Create a new .env file in root directory and add your private key:

RINKEBY_PRIVATE_KEY="MyPrivateKeyHere..."

If you don't have a private key, you can use one provided by Ganache (for development only!):

RINKEBY_PRIVATE_KEY="c87509a1c067bbde78beb793e6fa76530b6382a4c0241e5e4a9ec0a0f44dc0d3"

Run

In project folder run:

$ truffle develop

Then in truffle develop console compile the contracts:

truffle(develop)> compile

Finally migrate:

truffle(develop)> migrate

To test:

truffle(develop)> test

or:

npm run test

Coverage

Solidity Coverage

To run Solidity Coverage reports:

$ npm run coverage

Keep in mind solidity-coverage now expects a globally installed truffle. Coverage report available here.

Notes

The pay period is simple an uint but it could easily be set to an actual time frame if needed.

Issues/Bugs

Wrong Contract Address

When migrating

Error: Attempting to run transaction which calls a contract function, but recipient address 0x8cdaf0cd259887258bc13a92c0a6da92698644c0 is not a contract address

Solution: delete contents of /build/contracts and recompile.

Not Enough Funds during test

When testing in truffle develop

Error: sender doesn't have enough funds to send tx.

Solution: restart truffle develop. Notes: truffle does not reset accounts balance on multiple runs.

Solidity Coverage testrpc ghost process

After running solidity-coverage, testrpc remains a ghost process. Solution: kill it with:

$ npm run stop

and run coverage again:

$ npm run coverage
