March in Review: Cellframe Ecosystem Highlights

March 2026 was a busy month for the Cellframe ecosystem projects. Teams continued to develop infrastructure, launch new products, and prepare major updates.

Here is what happened in March across Node.sys, Dotflat, KelVPN, QEVM, and CPUNK.

Node.sys A post quantum L1 digital infrastructure for decentralised manufacturing and automation, with its own NYS token.

In March, the DeFactory partner network expanded significantly. Dozens of new companies joined the ecosystem from industrial refrigeration and climate solutions, machine tool manufacturing, and food tech. This strengthened the project's industry diversification and opened up additional opportunities for real world adoption of the technology.

As part of the DeFactory platform's development, the Node.sys team actively took part in key industry events to raise project visibility. They also worked on finding new partnerships and more through networking.From March 24 to 27, the team presented the project at Modern Bakery 2026, an exhibition focused on engineering solutions for bakeries and food production.On March 27, they participated in the Global Tech Forum 2026 conference, where discussions covered digital transformation, automation, IT solutions for business, and AI applications.

Dotflat An asset backed flatcoin with stable purchasing power.

In March, the team focused on a major overhaul of the DFC frontend to make the app more convenient and stable. Previously, the interface was problematic. The RPC provider worked correctly only when MetaMask was enabled; disabling it caused a CORS error. In addition, request limits (200,000 to 400,000 per month) created a heavy load, because each page reload required dozens of calls for each of the nine contracts.

To solve these problems, a block watcher worker was implemented. This is a server that collects all transactions and events from our contracts in real time from two independent sources (Etherscan and Rivet) and stores the data in an internal Redis cache. This allows the frontend to pull information directly from the cache, which significantly speeds up performance and reduces blockchain load. The real cache hit rate is about 99.8%.

In addition, charts were added for all commodity instruments and for DFC itself. React Router was configured to correctly display URLs when navigating between pages, and many small bugs were fixed.

KelVPN A decentralised, quantum secure VPN service with its own KEL token.

One of the main focuses in March was a complete restart of the VPN. In effect, this is a new product rewritten from scratch with an updated architecture, new protocols, and a new transport layer.

App and architecture

A key stage of shared desktop mode development has been completed, and integration into the app has begun.At the same time, the team started a deep rework of the service part, the key component responsible for connecting to servers, stability, and traffic protection. As part of this work, a strategic decision was made to migrate the service to the C language, which will improve performance, reduce app size, and give more control over the architecture.

Stability

Throughout the month, work continued to improve the stability of the current version. A hotfix for macOS with service side improvements has been prepared and is now being tested before release.

VPN and infrastructure

The key focus of March was the VPN restart and network infrastructure development, which the team had been working on since November. This area is now in its final stage.An updated solution is essentially being created. Architecture and protocols have been rewritten from scratch, a new transport layer has been introduced, multihop connection support has been added, and modern development tools have been implemented.In parallel, DPI resistance has been improved, connection recovery and load balancing mechanisms have been enhanced, and the stability logic has been reworked. The new architecture scales not only to the VPN but to the entire network.

Additional note

The VPN solution is being developed as a separate library, opening up possibilities for integration into third party applications and services.

March was an important milestone, bringing releases with the updated architecture and new features closer. Next steps include rolling these changes out to user versions and continuing product development.

QEVM A platform for deploying quantum resistant, EVM compatible smart contracts.

Testnet launch

The testnet is now live and includes a basic set of components. The website has been updated, a Linux build for compiling Solidity contracts has been released, and the qWeb3 Web3 wallet (in dev mode) has been introduced.The network is generating blocks. An explorer and developer tools, qethers.js (with CLI) and purcjs, are available. You can already deploy smart contracts, with detailed instructions expected soon.

Testnet development

Functionality will be expanded step by step. Plans include launching staking, bridges to the Cellframe network, a faucet, and improving documentation.The testnet is completely isolated and does not affect the mainnet economy. A separate QEVM wallet is used for now, but compatibility with Cellframe Wallet and seed phrase import will be available in the future.

Testnet performance

The testnet is developing steadily and showing good results. The network is stable. Initial vulnerabilities have already been found and fixed through a bug bounty program.The architecture is proving highly efficient. Current tests have not reached the throughput limit, and the MEV protected transaction processing model outperforms a classic gas auction.

Smart contract testing

A number of Solidity smart contracts adapted for a 32 byte address system have been successfully recompiled and deployed. Partners are now auditing and testing new contracts, including a DEX, ENS, marketplace, DAO, and NFT solutions. Plans include expanding the range of testing and attracting more use cases. Overall, the system's functionality is performing excellently, and together with partners, QEVM continues to deploy more complex dApp solutions.The Web3 wallet already natively supports tokens, NFTs, and various transaction types.

Before mainnet launch

Staking implementation needs to be completed, and bridging mechanisms with the Cellframe mainnet need to be set up. The team also continues to expand the variety of smart contracts.

White label and migration

QEVM is developing white label solutions based on Cellframe shards. Projects receive a ready made infrastructure, tokenomics, and turnkey integrations.Migration from EVM networks follows a burn and mint model, with a vault mechanism planned for the future. Shards already interact via Cellframe, and cross network compatibility is planned for expansion.The testnet is being actively used. Users are deploying tokens and contracts, and a marketplace launch is expected soon.

CPUNK A project with quantum resistant security, providing safe and private communication for users.

In March, the CPUNK team focused on comprehensive platform development, from user features to deep infrastructure reworking. The project continues moving toward its core goal: creating a secure, private, quantum resistant environment for communication and digital asset management.

Instant messaging system

The system is now fully adapted for instant user status updates, online or offline, without adding extra load to the DHT.The parallel request architecture has been optimised, eliminating message sending delays. Push notifications are now truly instant, and message deletion syncs across all devices.For reliability, content hash based deduplication has been introduced, and auto reconnect ensures seamless connection recovery.

Multichain wallet

March updates made token management even simpler and clearer. You can now send multiple token types directly from the chat: CELL, CPUNK, USDC, USDT, ETH, SOL, TRX.Transaction history for ERC 20 (Ethereum) and SPL token support (Solana) with automatic account creation give you full control over your assets.For convenience, tokens are grouped. Multichain stablecoins are shown as a single balance. Transaction details have been redesigned with address book integration, and parallel balance updates with background auto refresh keep your data current.

Built in DEX

Token swapping is now safer and faster thanks to integration with Jupiter (Solana), Uniswap V2/V3, PancakeSwap V2/V3, and Cellframe DEX.Swaps are executed directly on chain without intermediaries, and MEV and sandwich attack protection is provided via Flashbots Protect.Additionally, slippage protection with configurable limits has been added, and the swap confirmation interface has been completely redesigned for clarity and ease of use.

Nodus network infrastructure

The Nodus network received a major update, improving stability and speed.The production cluster now consists of 7 nodes, and the dedicated port architecture has been optimised for clients, node to node communication, channels, and consensus.The updated Kademlia DHT replication system uses routing via K nearest nodes, and automatic selection of the lowest latency node ensures fast response times.A dynamic consensus participant list and an increased maximum value size (up to 4 MB) allow safe transmission of large images and media.

Finally, March's biggest news is fundamental

The biggest change in March is not a new feature, but a fundamental system rebuild.The team completely removed the external OpenDHT dependency and replaced it with Nodus, a custom implementation in pure C built from scratch. Every line of code now belongs to CPUNK.This also made it possible to license the core under Apache 2.0, making the infrastructure available for use, forking, and development without being tied to third party vendors.The main goal is private, post quantum communication on a secure and transparent codebase.
