based on the results of the Lido DAO Snapshot vote, Lido has revoked the official endorsement status of wstETH bridge endpoints on nine networks: zkSync Era, Mode, Scroll, Mantle, Swell, Zircuit, Soneium, Polygon PoS, and Lisk.The funds of users holding wstETH on these networks remain safe, and no action is required. This revocation is a governance decision and will not disable any bridges, invalidate tokens, or affect users' ability to bridge wstETH back to Ethereum. Future proactive monitoring, marketing support, and ecosystem development for wstETH on the affected networks will cease. Relevant network information will be updated on Lido's multichain page, documentation, and help center.

Odaily News, According to an official announcement, Binance Wallet has launched the Web3 API, a comprehensive set of API endpoints that allows developers, institutions, and advanced on-chain traders to programmatically access on-chain trading and market data through a single integration. The API supports multiple chains (including Ethereum, BNB Smart Chain, Plasma, Arbitrum, Polygon, Base, Monad, Optimism, Linea, and Solana), providing real-time market data, aggregated swap quotes, and on-chain transaction execution capabilities. Key features include: Market Data API (real-time token prices, candlestick/K-line data), Transaction API (aggregated quotes, token swaps, built-in MEV protection), Non-Custodial Architecture (no private key holding, local user signing), and Enterprise-Grade Reliability. Currently, there are zero service fees and zero positive slippage fees; all price improvements are returned to the user. This API is suitable for developers building DApps, on-chain trading bots, and AI agents.
According to an official announcement from Polygon, the Polygon zkEVM Mainnet Beta will officially initiate its shutdown process on July 1, 2026, leaving approximately two weeks until full service cessation. The team urgently reminds users to withdraw all on-chain assets and liquidity positions before this deadline, as failure to do so may result in irretrievable loss of assets.The shutdown details two distinct rules for different asset types: Locked funds deposited in various DeFi protocol contracts will not be supported for automatic migration and cannot be recovered after the deadline; only assets held directly in personal wallets that have not been bridged back to Ethereum Mainnet in advance will be automatically migrated by the system to Ethereum L1, where users can claim them via a dedicated page. The platform urges users to promptly complete pool withdrawals and cross-chain operations to avoid the risk of permanent asset loss.
According to MetaMask’s official blog, MetaMask has officially launched its first self-custodial wallet designed specifically for AI agents—MetaMask Agent Wallet—and will begin its Early Access Program on June 8, 2026. The wallet connects to AI agent frameworks via a command-line interface (CLI) and supports the full suite of DeFi functionalities—including token swaps, perpetual contracts, prediction markets, and liquidity provision—across all EVM-compatible chains (Ethereum, Arbitrum, Base, Avalanche, Optimism, Polygon, BSC, Linea, Sei) as well as Hyperliquid. On security, the wallet offers two operational modes: - Default “Guard Mode” allows users to set daily spending limits and protocol allowlists; transactions exceeding these rules require manual two-factor authentication (2FA) approval before execution. - “Beast Mode” grants advanced users greater autonomy, but malicious transaction detection and mandatory 2FA verification remain enforced. All transactions undergo transaction simulation, Blockaid threat scanning, and MEV protection. Secure transactions are backed by up to $10,000 per month in transaction protection. Users retain full control of their private keys and can export their seed phrase at any time. The full public release is expected this summer.

According to PR Newswire, the Open Transaction Layer (OTL) officially launched on May 28 as an open industry initiative aimed at establishing a unified transaction coordination standard for on-chain finance. OTL defines shared protocols among institutions, non-custodial wallets, and AI agents for identity verification, messaging, and transaction coordination—covering the entire transaction lifecycle, including discovery, compliance, and settlement. The founding alliance comprises over 25 members, including leading financial institutions, payment service providers, and blockchain foundations such as Fireblocks, Checkout.com, Cross River Bank, MetaMask, Robinhood, Securitize, Wintermute, Solana Foundation, and Polygon. OTL’s technical specifications are built upon mature standards including W3C Decentralized Identifiers (DIDs) and ISO 20022, and adopt a modular five-layer architecture covering Identity, Session, Transport, Messaging, and Application layers. The specifications have been published under an open-source license at otl.network, and the alliance is also open to additional institutional participation.
: Multiple institutions including Robinhood, MetaMask, and eToro, along with Fireblocks, Checkout.com, Cross River Bank, Securitize, Wintermute, and others, jointly announced their participation in the "Open Transaction Layer (OTL)" initiative, aimed at establishing a unified transaction coordination protocol layer for on-chain finance.OTL is positioned as an open protocol stack for coordinating identity verification, compliance validation, transaction messaging, and execution processes among wallets, institutions, and AI agents, addressing the integration fragmentation problem currently plaguing cross-institutional interactions in on-chain finance, where entities operate in silos.The current coalition members include payment companies, trading platforms, wallets, market makers, and custody and stablecoin infrastructure providers, including Robinhood, MetaMask, eToro, MoonPay, SoFi, Wintermute, among others, as well as foundations from multiple public chains such as TON, Solana, Stellar, and Polygon.

Cash App, the payment application from Block, now allows users to send and receive Circle-issued USDC stablecoins on Ethereum, Solana, Polygon, and Arbitrum. These transfers are currently fee-free. USDC stablecoins received via Cash App are automatically converted into U.S. dollar balances. This feature is not yet available to customers in New York State. Users must complete identity verification and are subject to transaction limits. Block has previously focused primarily on Bitcoin, including the development of mining hardware and the self-custody wallet BitKey. Earlier this year, Jack Dorsey described stablecoins as “moving from one gatekeeper to another,” while acknowledging the growing customer demand.
Block's Cash App is gradually rolling out stablecoin payment functionality to its nearly 60 million users. According to sources familiar with the matter, the feature currently covers approximately 25% of users and is expected to reach full 100% availability within this week.The core functionality supports users in depositing and withdrawing via USDC, allowing free transfers of funds between external wallets and Cash App balances, and using stablecoins as a settlement tool for payments rather than as investment products. It currently supports transactions across four blockchain networks, including Solana, Ethereum, Polygon, and Arbitrum. Due to the irreversible nature of on-chain transactions, incorrect addresses or unsupported network transfers may result in permanent loss of funds.Block CEO Jack Dorsey previously stated that despite his longstanding preference for Bitcoin, user demand for stablecoins has prompted the company to adjust its strategy.

A Uniswap governance proposal seeks to extend the protocol’s fee collection and burning infrastructure to BNB Chain and Polygon, and to complete the fee activation process on Celo—which previously failed due to a configuration error. The proposal includes: setting the V2 protocol fee recipient addresses on BNB Chain, Polygon, and Celo to TokenJar; and designating V3OpenFeeAdapter as the owner of the V3 Factory on the respective chains. Additionally, on Celo, the feeToSetter role and ownership of the V4 PoolManager will be transferred to CrossChainAccount. According to the proposal, fees collected on each chain will be aggregated into their respective TokenJars, then UNI tokens will be bridged cross-chain back to Ethereum Mainnet and sent to the burn address.
Polymarket staff member Shantikiran Chanal posted on platform X, stating that they have taken note of the security reports related to reward distribution, and that user funds and market settlements remain safe.
