Why this program matters

  • Without mastery of Ink!

  • for smart contracts on Substrate, your smart contracts expose critical vulnerabilities to malicious attacks.

  • 75 % of security incidents on Substrate blockchains stem from avoidable Ink!

  • errors, with an average cost of 3,7 millions d'euros per exploited breach.

  • Every month without solid skills, a development team loses 30 % productivity in debugging and exposes the company to cumulative financial losses of 50 000 euros.

  • Your career and your company's face total failure: stalled projects, a ruined reputation in the Web3 ecosystem, and a fatal lag behind the competition.
