MyCointainer, ultimate staking service platform

Choose favourite cryptoassets, transfer coins to staking wallet and profit off them

It started in mid-2018, few months after we finished G2A.COM's big redesign launch. Bartosz approached me about his startup idea, asking if I'd help develop it.

The timing was interesting. Crypto was at its peak — every company wanted their own token, everyone was calling internal currencies "coins," and there was massive R&D happening as people searched for product-market fit in crypto solutions.

But what caught my attention wasn't the tech — it was the business model. Simple and elegant: the project would make money when users make money.

Consistently delivered quality code in great time. Very hard working & precise.

Bartosz Poźniak, CEO @ MyCointainer

MyCointainer is a shared staking platform, here's how it works:

  • Some cryptocurrencies reward you for staking their coins
  • Think of it like a bank deposit — hold money, earn profit
  • In crypto, it's called proof of stake
  • The more coins you stake, the bigger your rewards
  • By pooling resources, users could earn 2X typical rewards
  • Platform takes a small commission from increased yields

From a customer's perspective, the math was simple: do it solo and make X rewards, or use MyCointainer and make 2X. We'd take our commission from those rewards. Everyone win.

2018

We launched version 1.0 at August 2018 with 20 supported assets. The setup was straightforward but powerful:

  1. Users get unique wallets after signup
  2. System tracks deposits and sets proper user balances
  3. Public explorer integration for complete transparency
  4. Any user could verify transactions on both the explorer and platform
  5. Automated reward sharing between all users
  6. Rewards divided into smaller chunks for quicker profits

Before launch, we secured a financial license in Estonia, letting us handle both FIAT and crypto in a compliant environment.

After launch we were focused on polishing the product, integrating more assets and partnering directly with coin developers.

By end of 2018, we supported 30+ assets and had 2000+ registered users. Also, we invited 2 more engineers to join the team.

We built MyCointainer 1.0 with the MERN stack (MongoDB, Express.js, React, Node.js).

The frontend is static files, including SEO pages. Express.js serves these files. The backend runs on the same Express app in /api/ routes.

We have background workers for wallet balance checks and other tasks. The workers are stateless, making them easy to scale. Some are dedicated to specific partner coins.

We also built an admin app for customer KYC, balance and rewards monitoring, giveaway setup, airdrop management, quick database fixes, and new modules for repeatable tasks.

2019

During the 2019, we were constantly improving the product based on user feedback:

  • Built-in exchange, allowing users to instantly swap and stake various assets.
  • Community portal, allowing users to earn more with various activities (for example, by referring friends or bug bounties).
  • Airdrops aggregator, allowing users to gain more earnings possibilities than ever before.

By end of 2019, we supported 44 coins, including direct partnerships with Waves, Neturino USD and QTUM, and had 10000+ registered users.

2020

At the beginning of 2020, we launched the POWER subscription, enabling various benefits for our audience, including 0% fee on staking rewards and cold staking possibilities.

By april 2020 we alreaded had 59 supported assets, including partnerships with Cardano, Solana, and others.

In April 2020 I decided to step away from the project for private reasons — needed to focus on other projects and family, as my wife and I were expecting a child.
