Blockchain-Technology- and Cryptocurrency-consulting, ICO- & Smart Contract developer

2017 - 2018
Munich, Berlin

Developing Smart Contracts on the Ethereum Blockchain. Currently we work together with EU-Lawyers bringing up Standards for Security Tokens, working together with the Ethereum Community and folks from openzeppelin.

As a blockchain and crypto currency enthusiast I consult lawyers, tax advisors and companies on these technologies. I help to build up knowhow around crypto currencies and blockchain from scratch. I am also a consultant, advisor and developer for ICOs especially for the Ethereum platform (ERC20).

With a team of specialists I've built an ICO-platform that is completely aligned with German law, backed by german ICO experienced lawyers. We offer all services along the whole ICO-process:

  • legal framework with our (external) lawyers
  • token economics
  • token engineering / Smart Contract development
  • webdesign for ICO sale platform / landing pages
  • Sale platform including:
  • Crypto payments (BTC, ETH)
  • Fiat payments
  • whitelisting
  • Token reservation in Pre-Pre ICO phase
  • ERC20 or ERC 721 based tokens
  • vesting contracts for team related tokens
  • referral-/affiliate program
  • hosting (via external hosting company in Berlin)

Quote: This way we can support any ICO team for everything that needs to be done in order to do a successful Crowdsale, while the team itself can fully focus on its own product.
