Token based on Truffle & Open Zeppelin

Hello developer,

we need support in launching a small app based on the ERC20 token.

Your job is split into the following steps/tasks:

-> setup a virtual box based on ubuntu for development purposed and do your development on this system

-> create the token and crowdsale smart contract based on ERC20 using Truffle & Open Zeppelin (a rough description is e.g. here: [login to view URL])

-> run a test together with us on the ropsten network

-> implement those security rules including bug bounty, totalSupply and all other issues mentioned here: [login to view URL] / if you need addtional ressources those can be found here: [login to view URL]

-> create our application as a website with the following functions

-> A can offer a deal which will be listed on the website - a deal includes a) a price in any ERC20 currency/in any ERC20 token, b) a description as text, c) a deadline

-> deal acceptance means that B sends the requested token to a smart contract

-> if A & B agree that the deal was successful (via private key - e.g using MetaMask) the token inside of the will be transferred to A, if A & B agree that the deal was not successful it will be transferred back. If A & B do not agree, we as admins of the website may decide if the funds are transferred in which portion to whom, so e.g. 0% to A and 100% to B, upside around or x% to A and y% to B.

-> inside of every transaction 4% of the token/funds will be transferred to our address

-> this funcationality again needs to be tested on ropsten network till the flow works fine

-> in the next step we need to do a review of code and the virtual box used for the development

-> as final step, we push the application live to the mainnet & will be tested a last time

At this stage the project is done and completed and the milestone will be paid.
