The crypto company LayerZero has forged a partnership with Conflux to roll out a blockchain-based SIM card (BSIM), co-developed by China Telecom. This partnership aims to simplify cross-chain fund transfers, leveraging LayerZero's innovative exchange mechanisms. While it's uncertain whether they can attract China Telecom's 390 million users, the LayerZero CEO remains optimistic. 
Polygon Labs has launched its Chain Development Kit (CDK), a software tool designed to help developers create Ethereum Layer 2 chains powered by zero-knowledge proofs.
The toolkit will support an "Interop Layer," a new protocol that aggregates zero-knowledge proofs from multiple Polygon chains and secures them on the Ethereum mainnet.
This move aligns with Polygon's shift towards creating more interconnected chains, similar to ecosystems like Cosmos and Polkadot. 
Coinbase and Circle, five years after jointly launching USDC, are evolving their partnership. Coinbase is acquiring an equity stake in Circle, emphasizing their shared vision for the financial future. To further its reach, USDC will launch on six new blockchains between September and October, expanding its multi-chain presence to 15. With clearer global stablecoin regulations, Circle will assume all governance, including smart contract management. The Centre Consortium, initially governing USDC, will dissolve. 
This initiative aimed at countering anti-crypto legislation by mobilizing the community.
Coinbase’s long-term plan is focused on cultivating a grassroots movement and building an engaged community that advocates for positive legal changes and crypto-friendly regulations.
This initiative marks the nation’s first ever independent on-chain advocacy organization, driven by and for crypto enthusiasts.
As of now, the initiative boasts 54 161 supporters on its webpage. New Kid on the Block: Bitgert's Daring Claims Unmasked
Bitgert's BRISE token functions on the independent BRISE Chain, handling over 100,000 transactions per second at no gas fees.

1. Preserve a unified, neutral, and open blockchain space.
2. Conduct blockchain modernization.
3. Ensure infrastructure availability.
Optimism aims to officially unveil this project and the first version of the new chain governance process after discussions with the community in the next governance season. Kyber Network Crystal and KNC Token: A Comprehensive Review
Kyber Network Crystal acts as a cross-chain liquidity aggregator, facilitating fast swap transactions for DeFi. Thanks to the Kyber Network, users of dApps, DEX, and DeFi solutions can tap into a multitude of liquidity pools to exchange assets with minimal fees. The Mantle Network is now live on mainnet
The Ethereum-compatible Mantle Network, a Layer 2 blockchain solution, has initiated its alpha mainnet launch at the Ethereum Community Conference in Paris. Following a period of extensive testing and development over six months, the network accomplished over 14 million on-chain transactions. 
London's Herodotus, in collaboration with StarkWare, has launched an "on-chain accumulator" tool that lets users read and verify any part of Ethereum's history. This tackles Ethereum's current limitation of validating only the last 256 blockhashes.
The tool uses "storage proofs," a cryptographic method, to confirm the validity of data. This could be a game-changer for creating permissionless account recovery systems and insurance protocols that rely on historical on-chain data. Onyxcoin (XCN): An Overview of the Coin and Its Features
Onyxcoin (XCN) is a cryptocurrency that powers the Onyx ecosystem, tailored for the corporate sector. Initially introduced as an altcoin called Chain (CHN), it was rebranded to Onyxcoin in March 2022, coinciding with the launch of a new smart contract. 
Social app friend.tech has recorded protocol fees amounting to more than $1.42 million within the past 24 hours, positioning it among the top three crypto projects in terms of user-paid fees. It now stands as the third-highest project for user-paid fees, following Ethereum and Lido Finance, according to data from DeFiLlama. Built on Coinbase’s Base Layer 2 chain, friend.tech is a social app that integrates with X (Twitter). It allows users to trade tokenized shares linked to each other’s profiles. Shareholders enjoy exclusive content access and private chat rooms in X. 
DeBank has introduced a new Layer-2 solution based on OP Stack for user experimentation. It's now live for testing, and the mainnet is slated for 2024.
According to an official briefing, developers have accomplished cost reductions ranging from 100 to 400 times for specific transactions, all the while targeting gas expenditure.
Besides, to fortify user defense and trim L1 data leaks, transactions will be signed with a specially devised second-tier private key. Frax Finance: A Self-Sufficient DeFi Ecosystem
Frax Finance stands out as a DeFi platform that hosts its own decentralized stablecoins, an automated market maker, a lending platform, a cross-chain bridge, and native tokens. By the close of 2023, this ensemble will incorporate an L2 blockchain. For the time being, the Frax protocol is running on Ethereum. 
A Twitter debate has erupted, speculating that Sam Bankman-Fried (SBF) might be involved with the BALD memcoin rugpull.
Blockchain analysts delved into the developer’s on-chain history and discovered a connection between the wallet address deploying the BALD token and ETH funding from wallets linked to FTX and Alameda Research.
An anonymous DeFi commentator suggested that this link might indicate SBF’s attempt to recover some losses.
Data editors found that the same wallet address had made numerous transfers (400) to blacklisted USDT addresses and appeared to have strong connections with Alameda Research. 
Arkham Intel Exchange has acknowledged two on-chain investigators with approximately 9,519 ARKM (valued at ~$5,000) for information on Do Kwon & Terra's wallet holdings.
This new data suggests a potential inconsistency in Terra's previous declaration of possessing a single Luna Foundation Guard wallet. 
Bobby Dresser, the CEO of Optimism Foundation, announced on GitHub that they have approved proposals from O(1) Labs and RISC Zero for the integration of zero-knowledge proofs.
O(1) Labs suggests creating a new solution based on the Kimchi system, currently used in the Mina Protocol project. This move is expected to enhance both the performance and security of cross-chain communication. Axelar Reveals Partnership with Microsoft
Microsoft Corporation and the cross-chain protocol Axelar have declared a strategic alliance aimed at merging public and private blockchains. This collaboration positions the Axelar project on the Microsoft Azure platform, marking it as the first cross-chain protocol to be accommodated within the Microsoft developer store.
