  1. Technical/Product Advances

DEX Protocol

Additional refinements to the test user and code structure of the EVM contract version, and an external code audit will be conducted soon.

Optimized and improved the API interface services related to the EVM contract version, including transaction notifications, balance inquiries, transaction liquidity inquiries, etc.

The interface for adjusting transaction fees is reserved. Through economic incentives to enhance the income of ecological participants (traders, parallel chains, liquidity providers and market makers, etc.) and help the ecological development.


Through modeling abstraction and architectural reorganization, the DEX DApp has been able to access two different implementations of the DEX Protocol (EVM contract version and Module version) simultaneously. This will effectively smooth out the cognitive friction and improve the user experience, allowing users to migrate smoothly from the previous single-chain DeFi ecosystem to the complex structure of the Polkadot DeFi ecosystem.

Since the kernel mechanism of the EVM contract version is very different from that of the Module version, DEX DApp has done a round of adaptation design for the EVM contract version, which includes account address conversion and additional transaction authorization process.

By using the Batch Transaction function of Polkadot network, we are able to complete the “Authorization + Exchange” function in one click.

SlotVault DApp

The first batch of partner projects have basically been accessed. For each project, users will experience different paths of use.

Mobile adaptation is complete. Users will be able to access SlotVault directly from major decentralized mobile wallets (e.g. imToken, Math Wallet, TokenPocket, etc.).

Astar (formerly Plasm Network)

  1. Renamed Plasm to Astar Network

Because of the name “Plasm”, it is often thought of as a Layer2 related project. In reality, Plasm is not a Layer2 project, it is a multi-chain dApp hub on Polkadot, supporting Ethernet VMs and WebAssembly, and Layer2 is not the main feature, but only a complementary feature. So Plasm team decided to update the brand and change Plasm to Astar Network!

2、Sota interviewed by Microsoft

Our goal is to build an open, transparent and sustainable platform for Web 3.0. Astar Network will be a decentralized platform. We have already started talking to cloud providers like Microsoft and Amazon.

  1. Shiden launches Crowdloan campaign at Kusama

The third auction of Kusama should start and the highest bidder is currently Shiden, after winning the auction, Shiden will become a Kusama parallel chain and then Shiden will be launched step by step. So our first phase is to win the auction and in the second phase to prepare the smart contract functionality and collect people to stabilize the whole network. Our third phase is to integrate XCMP to develop cross-chain use cases.

  1. Partnership with Oraichain

Plasm Network announced a partnership with Oraichain, which enables the two companies to work together to integrate products, services and AI data to extend both companies’ AI ecosystem offerings. Through this partnership, we are bringing AI data into our ecosystem for developers to use on Shiden and Plasm Network.

This new partnership connects Oraichain with the Plasm ecosystem, a hub of dApps on Kusama and Polkadot, to help accelerate the development of both platforms. We are working on cross-VM communication (X-VM) libraries for the Shiden and Plasm networks, which makes Oraichain available to all developers building in the Plasm ecosystem.

  1. Stake Technologies, the company behind Plasm & Shiden, closed a $10 million strategic funding round!

Stake Technologies, the core company behind Plasm Network and Shiden Network, announced a $10 million funding round led by Distributed Capital with participation from other notable investors including Hypersphere Ventures, Gumi Cryptos, IOSG Ventures, TRG Capital, AU21 Capital, Digital Strategies, SNZ, Digital Strategies, Sub0 Capital, Altnomy, East Ventures, and others. The round also included Nobuyuki Idei, a well-known angel investor and former CEO and chairman of Sony.

  1. Plasm Network/ Shiden Network announced a partnership with doublejump.tokyo, the largest NFT content creator in Japan! Will expand Plasm and Shiden’s ecosystem by introducing NFT.

7、Astar introduces X-VM

Our vision for X-VM is to build an abstraction layer that allows smart contracts to execute calls and read stored data from different contract engines (virtual machines) and languages (e.g., interacting with Solidity dApps written in ink!).

As Dr. Gavin Wood mentioned earlier, WebAssembly is the future of smart contracts, but Ethernet virtual machines are also important now. The WASM-based engine has a bright future, as there are many great developers like Patract Lab who are making WebAssembly easier for developers to use on Polkadot.

However, we still see the value of EVM as we closely follow the latest developments in layer2 solutions for Ethernet, such as Optimistic Rollups and ZK Rollups. Rollups.

6、On June 21, Crust was invited to participate in the Moonbeam Astronaut Alliance roundtable discussion to share thoughts on the layout of multi-chain ecology.

7、On June 25, in order to make more people understand and use Crust for file storage, Crust launched [Data Creates Value] campaign, which lasts for 180 days with a total reward of 54,000 CRU. During the campaign period, users can choose to become [Data Provider] (get data computing power by storing files, thus getting CRU reward, suitable for users with large storage needs) or [Data Guarantor] (by providing CSM guarantee pledge for data arithmetic) to get the corresponding CRU rewards.

2、Ecology/product cooperation

Project Collaboration: Litentry x iMe

In Litentry’s identity aggregation protocol, users’ identity data (e.g. transfer transaction records, IDO participation) can be used to generate personal reputation values in a privacy-encrypted environment. By partnering with iMe, we can integrate data from iMe and Telegram so that users can use their behavioral data on the platform to generate reputation values for better DeFi services.

Project Collaboration: Litentry x Automata

We have entered into a partnership with Automata to enhance the privacy protection of Litentry’s identity score computation layer. Through a secure hardware approach based on the trusted execution environment Intel SGX, Automata ensures that Litentry’s identity calculation is performed in an isolated and shielded environment from any malicious actor’s surveillance. After Automata completes the computation, the result is encrypted using the request signing key from Litentry and recorded on the blockchain, and the outside world is required to decrypt the computation with a private key. This ensures that no outside parties can observe any of the computation process or the data used. With this collaboration, we hope to work with Automata Network to prevent potential data leakage during the identity score generation process.

Project Collaboration: Litentry x Encointer

Litentry and Encointer had an in-depth discussion on how DID could be applied to implement such a system – Litentry’s DID solution is highly Sybil-proof and anonymous. We believe that the integration of Litentry’s DID system into Encointer’s protocol will have the potential to greatly simplify the process of registering and proving users’ identities on the Encointer dApp. Encointer is currently experimenting with projects using random pseudonymous key signing parties. Their entity proof of attendance can be used as personality verification and can be used to complement the associated aggregated identity features in the Litentry protocol.

  1. Community/Marketing Events

Litentry was a guest on Clubhouse’s “PlatOn Talk” to discuss the application of DID in DAO governance and the current state of DID business.

The second episode of Litentry & Friends was released, featuring Victoria Gavrilyuck from iMe and Lilly M. Dobreva from Litentry to discuss the potential applications between DID and instant messaging.
