Weekly Hot Project Updates: Ethereum plans to alleviate Layer 2 fragmentation, Aave v4 officially launched, Dmail and Magic Eden wallets will be shutting down, etc. (0329–0404)

1. Solana Foundation announces the launch of Solana Agent Skills link

Solana Foundation announced the launch of Solana Agent Skills, enabling developers to directly embed pre-built skill components into AI tools to interact with the Solana ecosystem. The official statement says the relevant components can be quickly connected via a one-line install, for building AI agents with on-chain Solana operational capabilities.

2. Ethereum Foundation backs the “economic zone” framework, aiming to ease Layer 2 fragmentation link

Gnosis and Zisk propose the “Ethereum Economic Zones” (EEZ) framework, aiming to achieve coordinated operation between the Ethereum mainnet and various Layer 2 networks through shared infrastructure, reducing redundant development and technical frictions, and improving user experience; the Ethereum Foundation has participated in funding the project. The plan aims to mitigate Layer 2 ecosystem fragmentation by unifying the execution environment and using an ETH payment mechanism by default.

3. Polygon launches a private mempool, enabling MEV protection via one-line RPC integration link

Polygon announced the launch of a private mempool (Private Mempool), aiming to protect transactions from frontrunning and sandwich attacks. This feature allows developers to connect to the system by changing just one RPC URL; transactions will bypass the public mempool and be sent directly to block producers responsible for producing blocks under the verification set, ensuring the transaction order cannot be manipulated. Polygon said this architecture solves common malicious MEV issues seen in applications such as Polymarket while maintaining decentralization.

4. Base lays out its 2026 development priorities, focusing on tokenized markets, stablecoin payments, and the developer ecosystem link

Coinbase’s Ethereum Layer 2 network Base released its 2026 development priorities, focusing on three areas: tokenized markets, stablecoin payments, and the developer ecosystem. Specifically, it includes advancing on-chain trading of real-world assets such as stocks and commodities, expanding stablecoin payments and multi-asset liquidity, and continuing to invest in developer tools and AI on-chain application support. In addition, Base said it will further reduce reliance on Optimism OP Stack and move more toward building its own infrastructure to improve independence and scalability.

5. TON launches Sub-Second upgrade, completing full mainnet activation on April 7 link

TON Core announced that the Sub-Second upgrade has started deploying on the mainnet. This upgrade belongs to an update at the consensus layer, aiming to enable sub-second confirmations and improve on-chain responsiveness. The upgrade plan includes completing validator node version updates on March 31, having validators vote on April 2 to activate the new consensus on the base chain and increase block production frequency, and enabling a fast consensus mechanism across the base chain and main chain in full on April 7.

6. Uniswap Foundation discloses 2025 financial summary: holds about $85.8 million in assets link

The Uniswap Foundation published an unaudited financial summary for fiscal year 2025. As of December 31, 2025, it holds $49.9 million in cash and stablecoins, 15.10 million UNI, and 240 ETH. Based on year-end prices, total assets are approximately $85.8 million. The foundation said its existing funds are expected to support operations through January 2027, including about $106.2 million earmarked for grants and incentives, and another $26.3 million for operating expenses and employee token incentives. In 2025, it made new grant commitments of about $26.0 million, with about $11.0 million already disbursed.

7. Aave officially launches v4 upgrade on Ethereum link

Aave officially launched the v4 upgrade on Ethereum. Developed over approximately two years, this version aims to expand DeFi lending use cases from crypto-native assets to real-world assets (RWA) and institutional credit markets. The new architecture supports different types of lending markets running independently while sharing the same liquidity pool to improve capital efficiency and support more complex lending conditions. Aave founder Stani Kulechov said that in the future, more DeFi growth opportunities will come from value outside the chain and traditional financial scenarios.

In a report from the Bank of Canada, Aave V3 saw no bad loans in 2025. The total loan size was approximately $6.0 billion, utilization was about 40%, and the net interest spread was 0.64%. Research based on on-chain data analysis from January 2023 to May 2025 indicates that overcollateralization and automated liquidation mechanisms effectively prevent lenders from losses, but the risk is mainly borne by borrowers; at the same time, compared with traditional credit systems, it reduces capital efficiency. Meanwhile, platform revenue is highly concentrated in assets such as WETH, USDT, and USDC, and leveraged loop trades account for about 20% of the borrowed amount. Liquidation losses account for about 10% to 30% of the liquidation size, and have no significant sustained impact on market prices.

8. Aster adjusts its token release mechanism, switching to distribution only via staking link

In an announcement from Aster DEX, the project has canceled the original ecosystem token release mechanism of roughly 78.4 million tokens per month (about 1% of the maximum supply) and will instead distribute tokens only via staking rewards. Under the new mechanism, the current weekly release is about 450k ASTER tokens (about 1.8–2.25 million per month), a sharp reduction in new circulating supply compared with before. The project said that since the TGE in September 2025, ecosystem and community tokens have not been used, aside from staking rewards; the relevant addresses can be verified on-chain.

9. Decentralized email project Dmail Network will gradually shut down all services starting May 15, 2026 link

Decentralized email project Dmail Network released an official announcement stating that the project will gradually shut down all services starting May 15, 2026. The team said that the costs of decentralized email infrastructure in bandwidth, storage, and compute have long been too high and rise rapidly as the number of users grows. The commercialization and paid models have not formed a sustainable path; the token lacks clear large-scale usage scenarios, causing the economic model to be unable to close the loop. Combined with a cooling market and multiple rounds of fundraising and mergers and acquisitions that failed, core members have gradually left, and the remaining team no longer has the capacity to continue maintaining and iterating. The official said it has launched an email export tool and an account deletion feature. Users can export their emails to platforms such as Gmail; after completing the export, they can apply to delete their account. The relevant data (including emails, NFT domain names, points, and associated addresses, etc.) will be deleted. The official reminds users to complete the export before May 15; at that time, the nodes will stop running and emails will be inaccessible.

10. Magic Eden wallet enters “Export-only” mode on April 1 and will be fully shut down in May link

Magic Eden’s native multi-chain wallet officially entered “Export-only” mode starting April 1, 2026. The wallet has been delisted from major app stores, and users can currently only export private keys or seed phrases, with no ability to carry out new transactions or activities. Previously, Magic Eden closed its Bitcoin and EVM (including Ethereum, Polygon, and Avalanche) trading platforms in early March. The official reminds users to move their assets to other wallets as soon as possible. The wallet is expected to completely stop service on May 1, after which private keys can no longer be recovered through the app.
