The blockchain landscape is evolving rapidly, and with it, strategic rebranding efforts are helping shape clearer, more cohesive ecosystems. As of October 16, 2023, the Crypto.org Chain—a leading proof-of-stake network within the Cosmos ecosystem—has officially transitioned into the Cronos POS Chain, marking a pivotal moment in the expansion and unification of the Cronos blockchain ecosystem.
This change is not merely cosmetic. It reflects a deeper integration between two powerful blockchain networks under a unified brand, designed to enhance user experience, strengthen developer support, and accelerate mainstream adoption of decentralized technologies.
Understanding the Cronos Ecosystem
The Cronos ecosystem now consists of three core components:
- Cronos ($CRO): The native utility token powering both chains.
- Cronos POS Chain (formerly Crypto.org Chain): A high-performance, low-cost Cosmos-based proof-of-stake blockchain serving as the foundational "layer zero" for the ecosystem.
- Cronos EVM Chain: The Ethereum-compatible Layer 1 blockchain that hosts over 500 decentralized applications (dApps) and supports a thriving DeFi and NFT community.

With this rebrand, the Cronos POS Chain reinforces its role as the secure backbone of the ecosystem—issuing $CRO, securing consensus, and enabling cross-chain communication through Cosmos SDK innovations like IBC and inter-chain accounts.
The primary domain for the Cronos POS Chain is now cronos-pos.org, while the Cronos EVM Chain retains cronos.org. All previous URLs from crypto.org will gradually redirect to their new counterparts, with full deprecation expected by March 2024.

Why the Rebrand Matters
Unifying the Crypto.org Chain under the Cronos brand brings clarity and synergy to an already robust ecosystem. Both chains share a common mission: expanding access to decentralized finance, digital ownership, and blockchain-powered innovation for millions of users worldwide.
By aligning under one umbrella, the ecosystem offers:
- Consistent branding across tools, wallets, and developer resources.
- Streamlined user experience for holders, traders, and developers interacting with $CRO.
- Stronger technical collaboration between teams building on both chains.
At the protocol level, there are no changes. The Cronos POS Chain continues operating with the same validators, security model, and performance metrics that have made it one of the top three Cosmos chains by staked value—securing approximately $350 million across more than 100 active nodes.
To date, the network has processed around 33 million transactions, with average fees as low as $0.00001, making it ideal for micropayments, NFT minting, and high-frequency use cases.
Introducing the Cronos POS Chain
Cronos POS is a public, open-source, permissionless blockchain built using the Cosmos SDK. Designed for speed, scalability, and accessibility, it functions as a decentralized public good—supporting real-world applications such as:
- Instant peer-to-peer payments
- Low-cost NFT marketplaces
- Cross-chain asset transfers via IBC
- Decentralized identity and governance systems
Its native token, $CRO, ranks among the top protocol tokens in the Cosmos ecosystem and serves multiple functions:
- Staking rewards for validators and delegators
- Transaction fee payment
- Governance participation
- Utility across partnered platforms
Major industry players—including Crypto.com, Ledger, Coinbase, and Alchemy—already integrate with or support the Cronos POS Chain. Notably, Crypto.com uses this chain to power key services like Crypto.com Pay and Crypto.com NFT, leveraging its efficiency and reliability.
As part of the broader Cosmos ecosystem, Cronos POS benefits from cutting-edge modules such as:
- Inter-Blockchain Communication (IBC)
- Inter-Chain Accounts (ICA)
- Inter-Chain Security (ICS)
These features open doors to future innovations like shared security models and cross-chain smart contract execution.

The Rebranding Roadmap: A Phased Transition
To ensure a smooth migration, the rebrand unfolds in three clear phases:
Phase 1: Official Rebrand Launch (October 16, 2023)
On this date, the Crypto.org Chain was officially renamed to Cronos POS Chain, with new domains rolled out:
- Main site: cronos-pos.org
- Documentation: docs.cronos-pos.org
- Mainnet Explorer: cronos-pos.org/explorer
- Testnet Explorers: Updated paths under
/explorer/for Croeseid 4 and 5
Phase 2: URL Migration & Redirects (October – December 2023)
All remaining crypto.org endpoints are being systematically replaced. Legacy URLs redirect to new cronos-pos.org equivalents. Users receive updates via blog posts and Discord announcements.
Phase 3: Full Deprecation (End of March 2024)
By this milestone, all crypto.org infrastructure related to the former chain will be retired. Users must update integrations, API calls, and wallet configurations accordingly.
Throughout this process, network operations remain uninterrupted. No chain forks, token migrations, or wallet updates are required.
Future Outlook: Building Synergy Across Chains
Looking ahead, both the Cronos EVM and Cronos POS chains are committed to advancing the Cosmos ecosystem. Joint exploration of next-generation features includes:
- Enhanced node storage optimizations
- Wider adoption of IAVL+ data structures
- Implementation of Inter-Chain Security (ICS) for shared validator sets
- Cross-chain governance models using Inter-Chain Accounts
Developers and community members are encouraged to contribute ideas through the official Cronos Discord server, where ongoing discussions shape the roadmap.
The combined ecosystem already supports thousands of transactions per second across multiple layers. With layer-2 solutions like Caldera’s optimistic rollups deployed atop Cronos EVM, scalability continues to expand—enabling high-throughput applications without sacrificing decentralization.
Frequently Asked Questions (FAQ)
Q: Has the Crypto.org Chain been replaced or forked?
A: No. The Crypto.org Chain has been rebranded to Cronos POS Chain. It remains the same blockchain with identical protocols, consensus mechanism, and tokenomics.
Q: Do I need to update my wallet or migrate my $CRO tokens?
A: No action is required. $CRO remains unchanged. Wallets like Ledger and Trust Wallet automatically recognize the rebranded chain.
Q: What happens to old crypto.org links?
A: Most URLs now redirect to cronos-pos.org. These redirects will remain active until March 2024, after which they may cease functioning.
Q: Is $CRO now used on both chains?
A: Yes. $CRO is the unified utility token for both Cronos POS and Cronos EVM chains—used for staking, fees, governance, and dApp interactions.
Q: How does Cronos POS differ from Cronos EVM?
A: Cronos POS is a Cosmos-based proof-of-stake chain focused on security and low-cost transactions. Cronos EVM is an Ethereum-compatible chain optimized for smart contracts and dApps.
Q: Can developers build on both chains simultaneously?
A: Absolutely. Developers can leverage IBC to create cross-chain applications that interact seamlessly between Cronos POS and Cronos EVM.
The evolution from Crypto.org Chain to Cronos POS Chain represents more than a name change—it's a strategic step toward a unified, scalable, and interoperable blockchain future. As part of a multi-layered ecosystem bridging Cosmos and Ethereum worlds, Cronos stands ready to empower developers, users, and innovators in the next era of decentralized technology.
