Cronos (CRO) serves as the foundational settlement currency for the Cronos chain and is the native token of the Crypto.org blockchain. It functions as an integral utility asset within a broader, expanding digital ecosystem.
Operating as an Ethereum Virtual Machine (EVM)-compatible chain, Cronos runs in parallel to the Crypto.org chain. Its primary goal is to bolster the Creator Economy through decentralized applications (DApps) in sectors like decentralized finance (DeFi) and gaming finance (GameFi), positioning itself as a potential infrastructure component for the metaverse. A key advantage of Cronos is its ability to process transactions more swiftly and at a lower cost compared to the Ethereum mainnet, making it a more developer-friendly environment for DApps and smart contracts.
As the exchange token for crypto.com, CRO provides utility across payment, trading, and financial service use cases, powering the entire Crypto.com ecosystem.
The History of Cronos
Crypto.com was established in Switzerland in June 2016. Founded by Kris Marszalek, Rafael Melo, Gary Or, and Bobby Bao, the company initially operated under the name Monaco Technology GmbH.
The platform's native token was originally called Monaco Coin (MCO) before being rebranded to CRO (Crypto.com Coin). With the subsequent launch of the Crypto.org blockchain, the token's name was officially changed to Cronos, though it retained its CRO ticker symbol.
This evolution marked a significant step in the project's development, with CRO becoming the fundamental asset powering both the Crypto.org and Cronos blockchains.
How Cronos Works
The Cronos network is built on Ethermint, a scalable, high-throughput blockchain framework that offers full compatibility and interoperability with Ethereum. This technical foundation is the primary differentiator between the Cronos chain and the Crypto.org chain, as the latter does not use Ethermint and therefore cannot support applications built for EVM-compatible environments.
Cronos utilizes Tendermint Core's Proof-of-Stake (PoS) consensus mechanism. In this system, validators are required to stake a portion of their CRO holdings in a smart contract. This staking acts as a financial incentive for validators to process transactions honestly and efficiently. A significant benefit of the PoS model is its enhanced scalability and reduced energy consumption compared to the Proof-of-Work (PoW) mechanism used by networks like Bitcoin and early Ethereum.
As an open-source blockchain, Cronos enables all CRO token holders to participate in its governance. Any community member can propose changes, seek funding, and rally support through voting, ensuring a decentralized and collaborative development process.
By leveraging the Ethermint framework, Cronos effectively bridges the strengths of the Ethereum and Cosmos ecosystems. This interoperability and scalability are major attractions for dApp developers looking to migrate their projects from Ethereum.
The CRO Token
Originally named "Crypto.org Coin," the token was rebranded to Cronos to better reflect its decentralized nature and the goal of building a diverse, expansive network.
The total supply of CRO is capped at 30 billion tokens. This supply was set after a significant token burn event in February 2021, where 70 billion tokens were permanently removed from circulation.
The remaining tokens were initially created on the Ethereum blockchain following the ERC-20 standard before being ported over to the Crypto.org chain. Despite this migration, all the token's utilities and functions remained intact.
Primary Use Cases for CRO
CRO is a multi-functional token with several core utilities within its ecosystem:
- Staking: Network participants must hold and stake CRO tokens to engage in various activities. Node operators, delegates, and governance participants all use staked CRO to secure the network and earn rewards. Staking can be done directly on the Cronos platform using supported self-custody wallets or through staking services offered on exchanges like Crypto.com.
- Transaction Fees: CRO is used to pay for transaction fees (gas fees) on the Cronos chain. It is also the currency for settling transactions across the broader Crypto.com platform.
- Payments: The token facilitates payments across multiple Crypto.com products. Users can spend CRO using Visa-branded debit cards and through the Crypto Pay application.
- Investment and Yield Generation: Traders can speculate on the value of CRO on various exchanges. Within the DeFi ecosystem, CRO can be used for lending, borrowing, and providing liquidity to earn interest, bonuses, and cashback rewards.
Key Advantages of the Cronos Ecosystem
The Cronos network offers several compelling benefits for users and developers:
- EVM Compatibility: Its compatibility with the Ethereum Virtual Machine allows developers to effortlessly port dApps written in Solidity (Ethereum's programming language) to Cronos, greatly expanding its potential application library.
- Large Built-in User Base: As part of the Crypto.com family, which serves over 10 million users, Cronos has immediate access to a massive potential user base for its applications.
- Scalability and Efficiency: The PoS consensus mechanism provides a network that is significantly more scalable, cost-effective, and environmentally friendly than Proof-of-Work blockchains like Bitcoin and Ethereum.
- Interoperability: Built using the Cosmos SDK, Cronos can interoperate with the numerous other blockchains within the Cosmos ecosystem, fostering a connected and versatile network of chains.

Frequently Asked Questions
What is the difference between Cronos and Crypto.org?
Cronos is an EVM-compatible chain designed for hosting dApps and smart contracts, built using the Ethermint framework. The Crypto.org chain is its sister blockchain, which is not EVM-compatible and focuses more on payments and trading. Both chains use the CRO token as their native asset.
How can I earn passive income with CRO?
You can earn passive income with CRO primarily through staking. By staking your tokens to help secure the network—either by running a validator node or delegating to one—you receive staking rewards. Additionally, you can earn yield by lending CRO on supported DeFi platforms or by utilizing it within various liquidity pools.
Where can I securely store my CRO tokens?
CRO tokens can be stored in a variety of wallets. For those using the Cronos chain directly, self-custody options like the Crypto.com DeFi Wallet are popular. The tokens can also be held in other non-custodial wallets that support the Cronos network or in a custodial account on the Crypto.com exchange.
Is Cronos a good platform for developers?
Yes, Cronos is considered an excellent platform for developers, especially those already familiar with Ethereum. Its EVM compatibility means developers can use familiar tools like MetaMask and Hardhat, and easily migrate existing Solidity-based dApps to a faster and cheaper network.
What was the reason for the massive CRO token burn?
The burning of 70 billion CRO tokens in 2021 was a strategic decision aimed at reducing the total supply to increase the scarcity and potential value of the remaining tokens. This deflationary event is a common economic measure in crypto projects to benefit long-term holders.
Can I use CRO for everyday purchases?
Absolutely. One of the primary use cases for CRO is for payments. You can use it to pay for goods and services online and in-store through the Crypto.com Visa Card program, which converts crypto to fiat currency at the point of sale.
