The blockchain landscape is evolving rapidly, and one of the most significant transitions in the Cosmos ecosystem has just taken place. As of October 16, 2023, the Crypto.org Chain officially rebrands as the Cronos POS Chain, marking a strategic shift toward greater cohesion within the broader Cronos ecosystem.
This transformation isn't just cosmetic—it reflects a deeper integration between two powerful blockchain networks under a unified vision: accelerating mainstream adoption of decentralized technologies through seamless user experiences, robust infrastructure, and shared utility via the $CRO token.
Understanding the Cronos Ecosystem
The rebrand introduces a clearer structure to the Cronos multi-layered blockchain ecosystem, now composed of:
- Cronos POS Chain (formerly Crypto.org Chain): A high-performance, low-cost Proof-of-Stake (PoS) blockchain built using the Cosmos SDK, serving as the foundational “layer zero” network.
- Cronos EVM Chain: The Ethereum-compatible Layer-1 chain that supports smart contracts and decentralized applications (dApps), home to over 500 project teams and more than $300 million in DeFi Total Value Locked (TVL).
Both chains are unified under the $CRO utility token, enhancing interoperability, security, and economic alignment across platforms.

Why the Rebrand? Building Coherence for Growth
The decision to rebrand Crypto.org Chain as Cronos POS stems from a clear strategic objective: to unify branding, simplify user experience, and strengthen ecosystem synergy.
Despite operating independently at the protocol level, both chains share core values:
- Serving the global #CROFam community
- Driving mass adoption of crypto
- Leveraging cutting-edge Cosmos innovations like IBC, inter-chain accounts, and inter-chain security
By aligning under the Cronos brand, users and developers benefit from:
- Clearer navigation between chains
- Unified documentation and tooling
- Streamlined access to dApps, wallets, and services
- Enhanced trust through consistent branding
The Cronos POS Chain remains the **native issuer of $CRO**, secured by over 100 validators representing approximately $350 million in staked value—placing it among the top three Cosmos chains by total stake.
With nearly 33 million transactions processed and average fees as low as $0.00001, Cronos POS continues to deliver exceptional performance ideal for micropayments, NFT minting, and high-throughput use cases.
Introducing the Cronos POS Chain
Cronos POS is a public, open-source, and permissionless blockchain designed for scalability, speed, and affordability. Built on the Cosmos SDK, it leverages Tendermint’s Byzantine Fault Tolerant (BFT) consensus mechanism to ensure fast finality and high reliability.
Key Features of Cronos POS:
- Ultra-low transaction fees: Ideal for peer-to-peer payments and NFT projects requiring high-volume operations.
- High throughput: Capable of supporting thousands of transactions per second across multiple layers.
- Interoperability-ready: Native support for IBC enables seamless asset and data transfer across Cosmos-connected chains.
- Security-first design: Backed by a world-class validator network with a proven multi-year track record.
Major partners including Crypto.com, Ledger, Coinbase, and Alchemy already integrate with Cronos POS. Notably, Crypto.com Pay and Crypto.com NFT platforms run directly on this chain, serving millions of users worldwide.
As “layer zero,” Cronos POS provides foundational security and token issuance capabilities that empower higher-layer ecosystems like the Cronos EVM Chain.

Phased Transition: What Changed and When?
The rebranding follows a structured three-phase rollout to ensure minimal disruption:
Phase 1: Official Rebrand (October 16, 2023)
On this date, the new identity went live with updated domains:
- Main website: cronos-pos.org
- Documentation: docs.cronos-pos.org
- Mainnet Explorer: https://cronos-pos.org/explorer
- Testnet Explorers: Updated for Croeseid4 and Croeseid5
All existing URLs from crypto.org now redirect to their cronos-pos.org counterparts.
Phase 2: Gradual Endpoint Migration (October – December 2023)
Over the following weeks, all remaining endpoints were transitioned. Users received notifications via official blog posts and Discord updates. A full mapping of old vs. new URLs is available at:
https://docs.cronos-pos.org/for-users/new-brand-and-domains
Phase 3: Full Deprecation (End of March 2024)
By this milestone, all legacy crypto.org endpoints will be permanently retired. No protocol changes occurred—only domain and branding updates.
Users should update bookmarks, API integrations, and wallet configurations accordingly.
Looking Ahead: Innovation and Interoperability
The future of the Cronos ecosystem lies in leveraging breakthroughs from the Cosmos stack:
- Inter-Chain Security (ICS): Enables Cronos POS to share its validator set with other chains, boosting security across the ecosystem.
- Inter-Chain Accounts (ICA): Allows cross-chain governance and account management—users can control assets on remote chains without wrapping or bridging.
- IBC Enhancements: Improved node storage and IAVL+ optimizations increase efficiency and reduce operational costs.
These advancements open doors for:
- Cross-chain DeFi protocols
- Omnichain NFTs
- Decentralized identity systems
- Layer-2 rollups (e.g., Caldera’s optimistic rollups on Cronos EVM)
Community input is vital. Developers and stakeholders are encouraged to participate in discussions on the official Cronos Discord server to shape future integrations and collaborative upgrades.

Frequently Asked Questions (FAQ)
Q: Did the rebrand affect the $CRO token?
A: No. The $CRO token remains unchanged—same contract address, same utility across both Cronos POS and Cronos EVM chains.
Q: Do I need to swap or migrate my tokens?
A: No migration is required. All balances on Crypto.org Chain automatically reflect on Cronos POS under the new branding.
Q: Is Cronos POS an Ethereum-compatible chain?
A: Not natively. While it runs on Cosmos SDK, Ethereum compatibility is handled by the separate Cronos EVM chain. However, IBC bridges enable asset transfers between them.
Q: Can developers build dApps directly on Cronos POS?
A: Yes. Developers can create applications using Cosmos SDK modules. For EVM-based dApps, use the Cronos EVM chain instead.
Q: How does Cronos POS contribute to ecosystem security?
A: As the layer-zero chain, it secures the native $CRO token and supports inter-chain security models that protect satellite chains.
Q: Will old Crypto.org links still work?
A: Temporarily. All legacy URLs redirect to new cronos-pos.org addresses until full deprecation in March 2024.
