The Mchain Team

Greetings, Mchain Marine!

We are pleased to bring you exciting news about the latest updates we have made for the MAR token launch.

Network Switch: From BSC to Ethereum​

After careful evaluation and considering the valuable opinions of our community, we have decided to change the network for the launch of our MAR token. Although it was initially planned as a BEP20 token on the BSC network, we are happy to announce that MAR will be launched as an ERC20 token on the Ethereum network, allowing us to take advantage of all the benefits this network offers.

MAR ERC20 Token: A Fee-Free Experience​

We want the experience with the MAR ERC20 token to be as smooth as possible and scale up to the launch of Mchain v2. For this reason, the MAR ERC20 will be a standard token without reflection fees, facilitating transparent and direct transactions and promoting greater adoption and participation in our community.

Future Integration with BSC through a Bridge​

Following the launch of MAR ERC20, you will also enjoy the benefits of the MAR token on the BSC network. We are in the planning stages of a bridge that will allow a smooth connection between the Ethereum and BSC networks, expanding opportunities and accessibility for our community.

Stay Tuned for Upcoming Updates​

We will soon share more details, including the exact launch date. We are committed to keeping our community well-informed at every step of our journey.

Thank you for being a vital member of our growing community!

This section offers an in-depth guide on migrating from Mchain v1 to Mchain v2. As the process unfolds, we will continuously update and incorporate essential information to ensure a seamless transition for our users. Stay tuned and ensure you check back for the latest updates!

Explore Mchain v1 Holders in Learn Section

Ahoy, mariners! As we embark on this transformative journey through the turbulent waves of cryptography with Mchain, we're thrilled to introduce the maiden entry in our logbook — a testament to our collective voyage.

Today, we raise our metaphorical anchor and venture into the vast ocean of cryptographic information. As explorers of the digital age, it's only fitting that we maintain a logbook, much like the ship captains of old. This space, our very own digital "ship's log", will capture significant milestones, updates, and discoveries related to Mchain and the broader world of cryptography.

Why a Logbook?​

Every great journey deserves to be documented. A logbook serves not just as a record but as a beacon for others to follow, understand our trajectory, and, perhaps, embark on their own adventures. Here at Mchain, we believe in transparency, continual learning, and community engagement. Through this logbook, we aim to:

  • Chronicle our progression and the evolution of Mchain Docs.
  • Share insights and best practices from the realm of cryptography.
  • Engage with our community, seeking feedback and fostering collaboration.

What's Next for Mchain Docs?​

We're at the cusp of many breakthroughs. In the coming weeks, expect detailed tutorials, deep dives into complex cryptographic concepts, and exciting integrations.

As we set forth, remember that every journey encounters its fair share of storms and calm seas. However, armed with knowledge and a shared sense of purpose, we're confident of navigating through it all.

Our ship has set sail, and with the guidance of stars and the strength of our community, we're bound for great horizons. Stay tuned to our logbook for regular updates and insights. Here's to the uncharted waters ahead and the treasures we're yet to discover with Mchain!
