Overview of the Chain Ecosystem was formed in 2016 with the goal of speeding up the world’s adoption of blockchain technology and making cryptocurrencies accessible to everyone. The project is helping to reimagine banking by providing users with a comprehensive range of DeFi services, as well as the App, Exchange, and Visa Card.

The Chain, which uses the Cosmos Tendermint Core BFT consensus mechanism, is able to offer such a wide range of services because of its robust crypto-economic system and overall technical prowess. The ecosystem’s native currency is the CRO coin.

Project History

Monaco Technologies GmbH, founded in June 2016 by CEO Kris Marszalek and three other founding members, was the seed company for On July 6, 2018, the project was renamed started sending its Visa Card to users in APAC markets in October 2018, and a month later, the organization released the first version of the Chain protocol. proudly announced on December 19, 2018, that it had signed a Memorandum of Understanding (MOU) with Ledger, a blockchain cold wallet provider, to secure the protection of the platform’s funds.

This feature allowed customers to use the App’s products and services on demand while retaining a high level of security comparable to that of a cold wallet. began sending its Visa Cards to US customers in March of this year, and the platform surpassed one million users in September.

The platform grew at an exponential rate in 2020, and by October, the company had hired its 600th full-time employee and had over 5 million users.

When the founders of began working on the project, their goal was to assist individuals all over the world take control of their funds by safeguarding their identities and personal information.

To achieve this purpose, created a number of new services, many of which are integrated into the App, such as:

  • Crypto Trading (via the Exchange and App)
  • Crypto Earn
  • Pay
  • Crypto Credit
  • DeFi Wallet and DeFi Swap
  • Visa Card

As of this writing,’s flagship product, the App, supports over 80 crypto assets and seven types of fiat currencies, allowing users to purchase, sell, store, send, and track crypto assets securely.

Crypto Earn allows customers to earn interest on their cryptocurrency by paying out competitive annual dividends of up to 12%, depending on the term and asset type. CRO coin holders receive the highest dividends of any asset class. Pay is a mobile payment service that allows users to shop and pay using bitcoin through the App.

Users can get CRO coin payback on Pay Gift Card purchases and free peer-to-peer transfers with Pay Your Friends, among other benefits. Pay Checkout enables merchants to accept cryptocurrencies as a payment option and get paid instantaneously in their preferred fiat currency or cryptocurrency.

When compared to typical payment processors, merchants pay no processing fees for crypto payments or save up to 80% on fees. Users can get a loan instantaneously with no payment deadline and no credit check using Crypto Credit.

Users can borrow stablecoins by depositing CRO, BTC, ETH, and other assets. DeFi Wallet is a non-custodial, decentralized wallet that gives users more control over their funds.

DeFi Wallet features Chainlink price reference data, which provides DeFi tokens with decentralized price feeds. Users can also use DeFi Swap to swap and farm their DeFi assets, as well as gain up to Triple Yield for providing CRO currency liquidity and staking CRO coin, all through the Wallet.

Larger holders of CRO can stake their coins as validators on the Chain, earning incentive network rewards and settling transaction fees.

The App is also fully connected with the Exchange, which gives users access to over 80 cryptocurrencies for trading. Users can connect’s financial services and payment solutions with the Visa Card, in addition to all of the above features.

Users of the card can get up to 100% refunds on Amazon Prime, Netflix, and Spotify, as well as up to 10% return on all Airbnb and Expedia transactions (depending on card tier). Users may get even more benefits with Visa Cards, which offer up to 8% cash back on purchases depending on the card tier.

The amount of CRO coin a user has staked determines the card tier. Coins are normally held for a six-month lock-up period when staking CRO, during which time users can earn up to 12% APY on their staked CRO.

Without Tendermint’s BFT consensus process, which acts as a major piece of infrastructure for the Chain protocol, none of these services would be possible.

Tendermint’s fault-tolerant design makes it secure, resilient, and permissionless, while also allowing for high transaction speeds and low costs.’s advanced network of nodes also speeds up an on-chain settlement, payment infrastructure, and general service usability in the ecosystem.

CRO has a total supply of 100 billion coins, which came from five secure multi-signature wallets, each dedicated to a different purpose:

  1. Secondary distribution/launch incentives: 30%
  2. Network long-term incentives: 20%
  3. Capital reserve: 20%
  4. Ecosystem grants: 20%
  5. Community development: 10%

To preserve the project’s long-term health,’s founders determined that freezing 60% of the total CRO coin supply was in the best interests of the ecosystem.

The capital reserve and network long-term incentive allocation wallets will both stay locked until November 7, 2022. Following the successful launch of the Croeseid Testnet in October 2020, the ecosystem grants wallet will be frozen until the introduction of the new mainnet, which is anticipated as the next milestone.

Furthermore, the CRO coin allocation’s secondary distribution and launch incentives component (30 percent of the total supply) will be automatically transferred into its multi-sig wallet on a daily basis via a smart contract.

The following is the allocation of tokens per year for the next five years:

  • Year 1: 10% of the total circulating supply (10 billion coins)
  • Year 2: 8% of the total circulating supply (8 billion coins)
  • Year 3: 6% of the total circulating supply (6 billion coins)
  • Year 4: 4% of the total circulating supply (4 billion coins)
  • Year 5: 2% of the total circulating supply (2 billion coins)

The ecosystem began with MCO (Monaco coin) as its native cryptocurrency, but it has since transitioned to CRO coin for all in-network functions.

This move aims to create a next-generation cryptocurrency infrastructure for customers, with the goal of eventually unlocking a broader set of bitcoin-based DeFi features. MCO has been a main driver for the App and its numerous capabilities since the beginning of the ecosystem.

By November 2, 2020, all customers were required to convert their MCO into CRO coins via the App.’s services, including the Visa Card, the App, and trading and payment services integration, are now powered by CRO coin, and further App capabilities will likely be powered by CRO coin in the future.
