€5-35 EUR / hour

We're a fantastic startup Blockchain relation company in Europe. Maxime Thomas is my coworker. He already posted this project, but unfortunately, he took a mistake to set hourly rate. It's so urgent project, so hourly rate is not skilled(18 - 36 Euro), it's Expert(36+ Euro). We're really sorry, so I post this project again. Looking for a Mid-Level to Expert-Level Solidity Programmer to develop the Ethereum ER20 Contracts for 1 to 2 month project. Experience Required: - 3 years of professional programming experience in any language. Understanding of core concepts like object-orientation, data structures, and algorithms, and algebraic equations. - 1 year or 9000+ hours of recent experience programming in Solidity to develop real world, customized ER20 token contracts (This will not be a cookie cutter assignment). - Mid-Level to Expert Level understanding of Ethereum ER20 Contracts. Must be able to assist in developing requirements for ER20 token contracts. Must know what can and cannot be done, and understand pitfalls to avoid. - Willing to pay more based on relevant experience. - Must be able to debug, troubleshoot, and perform detailed testing on contract to ensure contract is correct before issuing it to the real Ethereum blockchain. - Must be able to communicate effectively in English (written and spoken). Preferred Skills: - Good understanding of stable tokens is preferred. Please provide the following. If no, don't apply, I'll ignore your proposal. - Your resume or CV. - Work sample of a Solidity ER20 Contracts you have done that has custom features. If you cannot provide code, please provide a detailed descriptions of how you customized the token and the types of issues you had to resolve to complete the assignment.

Hello, i'm a solidity smart contract developer, web3 dapps developer and have implemented custom blockchain-based solutions. I've 20 years of experience as a programer, now as a freelancer and external consultor i'm focused in blockchain technologies. A custom ERC20 contract i've done: My own project that includes a "freeze" of x amount of tokens from x address, that function is triggered from an external contract, also is a mintable token that can be minted from 2 sources depending the actual state of the project ecosystem. BTW i don't like to use cut 'n paste tokens like zeppelin. All my contracts are delivered fully functional and tested, you will recive a short video of the testing process to ensure that everything works as you requested. will send the token sample and cv via chat

I'm answering your two questions below in brief and can share more over screen sharing interview We have experience on token deployment. If there is any customization required like vesting, hard cap, keeping founders tokens in escrow. We usually do that customization in the token distribution or ICO contracts. As ERC20 is standard we usually don't change that standard because it may cause issues with wallets and exchanges. My Blockchain profile in brief - 2 yrs exclusive experience in Ethereum/Hyperledger blockchain. Over all IT experience - 10 plus years - Solid grip on Solidity, chaincode for Hyperledger, Truffle, Metamask, infura, remix. - Specialize in Solidity/Ethereum Smart Contracts, JavaScript connecting user interface to Blockchain. Using Truffle and Remix. - Creating ICO smart contracts, and support during campaign. - Developed multiple apps using Ethereum and truffle framework. - Deployed projects using IBM bluemix both 0.6 and 1.0 fabric versions. - Token sale and ICO’s - Have experience on "web3j" java library. - IBW Blockchain - Developed KYC solution by sourcing multiple data points - Music Industry use case - Developed solution for distributing songs and getting royalty to genuine artist via Blockchain. - Healthcare domain - Developed micro-insurance on Blockchain, automated claim processing You can try us free for few hours and continue only if you my service
