What Is the Neo MainNet Upgrade v3.10.0?

Neo-CLI v3.10.0 is the latest software release for the Neo N3 blockchain. Released on June 11, 2026, and deployed to TestNet on June 12, the upgrade is scheduled for MainNet activation on June 26 following stable testing.

Unlike traditional blockchain upgrades that introduce disruptive network changes, this release is fully backward compatible. Existing nodes remain compatible with the network, and operators do not need to perform a chain resynchronization.

The primary objective of the update is to prepare Neo's infrastructure for future enhancements, particularly the upcoming Gorgon hard fork. As a result, the release focuses heavily on code optimization, developer experience improvements, security refinements, and network reliability.

For most users, the transition should be seamless. However, node operators are encouraged to upgrade before the deployment date to remain synchronized with the latest network standards.

Gorgon Hard Fork Preparation

The most significant aspect of NEO v3.10.0 is its role in preparing the network for Gorgon.

The update introduces several under-the-hood improvements, including:

• Refactored VM JumpTable architecture for more efficient opcode execution.

• Fixes for SHL and SHR bitwise operations.

• Optimized opcode pricing calculations.

• Updated cryptographic verification mechanisms.

• Greater compatibility between Neo-CLI and NeoGo implementations.

These changes may appear technical, but they are essential for the future rollout of dynamic opcode pricing.

Currently, Neo uses a fixed-rate fee model. The Neo Council has previously approved a substantial reduction in execution costs, but implementation was delayed due to concerns that lower fees could increase vulnerability to spam attacks.

Gorgon aims to solve this challenge by introducing dynamic pricing, allowing normal transactions to remain inexpensive while making malicious activity increasingly costly.

For long-term investors, this represents a potentially significant catalyst for future ecosystem expansion.

Neo Wallet Upgrade and BIP-39 Support

Another notable improvement is the expansion of BIP-39 support.

Users can now fully import and export wallets using standard 12-word and 24-word mnemonic phrases. This enhancement aligns Neo with industry-standard wallet recovery methods already used across major blockchain ecosystems.

Benefits include:

• Simpler wallet backups.

• Easier account recovery.

• Improved onboarding experience.

• Better compatibility with broader crypto wallet standards.

Although this change may not directly affect NEO price action, improved usability often contributes to stronger ecosystem adoption over time.

New Neo Developer Tools and RPC Enhancements

Developers receive several meaningful upgrades in this release.

New RPC methods include:

• sign

• relay

• signmsg

• verifymsg

These additions simplify transaction management and improve communication between applications and the blockchain.

The update also improves transaction validation and debugging capabilities through:

• Enhanced error reporting.

• Dedicated "Expired" transaction status.

• Rejection of duplicate Conflicts attributes.

• Better contract execution diagnostics.

For developers building decentralized applications, these enhancements reduce friction and improve troubleshooting efficiency.

Infrastructure and Stability Improvements

Neo-CLI v3.10.0 introduces several infrastructure upgrades designed to strengthen network reliability.

Highlights include:

• DeferredRelay plugin for automated transaction relaying.

• Official Docker image for simplified node deployment.

• Consensus mechanism improvements.

• Storage snapshot leak fixes.

• Stronger RPC security defaults.

• Automated release workflows.

• Improved logging via Serilog.

Additionally, the network's MaxTransactionsPerBlock remains set at 200 on Neo N3 MainNet, maintaining consistency with prior governance decisions.

Collectively, these upgrades create a more stable and developer-friendly environment.

Why the Neo MainNet Upgrade Matters for Traders

Short-Term Market Impact

Historically, routine blockchain infrastructure upgrades tend to have limited direct impact on token prices unless they introduce major economic changes.

The Neo MainNet upgrade falls into this category.

Since there are:

• No token supply changes.

• No token migration.

• No chain split.

• No immediate fee reductions.

The direct effect on NEO and GAS valuation may be modest.

However, markets often react to narratives rather than technical details alone. Positive sentiment surrounding Neo's preparation for Gorgon could create temporary volatility around the June 26 deployment date.

Traders should monitor:

• Trading volume.

• Open interest.

• Social sentiment.

• Exchange announcements.

• Developer activity.

These indicators may provide early clues regarding market reactions.

Is NEO Bullish After the Upgrade?

The answer depends on the timeframe.

In the short term, NEO may experience limited price movement because the upgrade itself does not alter token economics.

From a longer-term perspective, however, the outlook appears more constructive.

The successful implementation of v3.10.0 demonstrates continued development activity, improved infrastructure, and progress toward lower-cost transactions.

If Gorgon eventually delivers dynamic fee pricing successfully, Neo could become more attractive for:

• DeFi applications.

• Blockchain gaming.

• NFT ecosystems.

• Enterprise adoption.

• High-volume transactions.

These factors could strengthen long-term demand for both NEO and GAS.

Therefore, while the current upgrade is not necessarily a standalone bullish catalyst, it may reinforce the broader bullish case for Neo's future development roadmap.

What to Watch Before June 26

As deployment approaches, traders should focus on several key developments:

Network Stability

Any unexpected issues on TestNet or during deployment could affect market confidence.

Exchange Communications

Major exchanges may publish maintenance notices or operational updates related to node upgrades.

Neo Council Announcements

Future details regarding the Gorgon timeline could have greater market significance than the v3.10.0 deployment itself.

Developer Activity

Increasing ecosystem activity may indicate growing confidence in Neo's infrastructure improvements.

Neo Ecosystem Update: N3 MainNet and Neo X

While much of the attention remains on Neo N3, traders should not overlook Neo X.

Neo X is Neo's EVM-compatible sidechain designed to support Ethereum-compatible applications. Around the same period as the Neo MainNet upgrade, Neo X has also been receiving enhancements, including support for Ethereum Osaka compatibility.

This creates an interesting dynamic within the broader Neo ecosystem.

As bridges, liquidity providers, and exchanges continue supporting Neo X, some activity may gradually migrate between N3 and the sidechain.

For traders, monitoring the relationship between these networks can provide valuable insight into ecosystem growth trends.

Important metrics include:

• Total value locked (TVL).

• Bridge activity.

• Developer migration.

• User growth.

• Exchange support.

Together, these indicators help paint a clearer picture of Neo's evolving ecosystem.
