Deep Dive
1. Mainnet v1.7 Performance Boost (10 March 2026)
Overview: This upgrade went live with about 30 minutes of network downtime. It primarily focused on backend improvements to make the network run more smoothly for developers and applications.
The core changes were optimizations to the Software Development Kit (SDK) tools and Remote Procedure Call (RPC) performance. These are the fundamental interfaces developers use to build and connect applications to the Cronos blockchain. By making these systems more efficient, the network can handle data requests and process transactions more reliably.
What this means: This is bullish for CRO because it makes the underlying infrastructure faster and more robust. A more efficient network attracts developers to build better applications, which can drive user adoption and increase the utility of the CRO token. For everyday users, this translates to more reliable dApps and a smoother overall experience.

2. POS Mainnet v7 Upgrade (20 May 2026)
Overview: Scheduled as the largest upgrade since launch, this update targeted the proof-of-stake (POS) chain that handles payments and NFTs. It required node operators to update their software at a specific block height.
The upgrade aimed to compress block times for faster transaction finality and improve compatibility with the Cronos EVM bridge. It also included adjustments to staking rewards and token emissions, designed to incentivize longer-term holding and make the tokenomics slightly more deflationary.
What this means: This is bullish for CRO because faster block times mean quicker payments and NFT settlements, improving the chain's competitiveness. The adjustments to staking and emissions could reduce sell pressure from new token issuance over time, potentially supporting the token's value. For users, it means a more responsive network for core transactions.

3. Smarturn EVM & Smart Account Upgrade (30 October 2025)
Overview: The "Smarturn" upgrade introduced significant enhancements to Cronos's Ethereum Virtual Machine (EVM) compatibility and added support for "smart accounts."
This update included new operational codes (opcodes) that allow for more complex and efficient smart contracts. A key feature was the implementation of EIP-7702, which lets regular wallet addresses temporarily act like smart contracts. This enables advanced functions like transaction batching, sponsored gas fees, and customizable wallet permissions without users needing to change their account type.
What this means: This is bullish for CRO because it significantly upgrades the platform's capabilities for developers, especially in DeFi and gaming. For users, smart accounts mean transactions can be simpler, cheaper, and more flexible—like having a wallet that can pay fees in different tokens or execute multiple actions at once. This improves the user experience and could attract more activity to the chain.
