Polygon zkEVM Mainnet Beta to Shut Down on July 1, DeFi Assets at Risk if Withdrawal Deadline Missed

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.

MetaMask Launches AI Agent Wallet Supporting Cross-Chain DeFi Operations with Built-in Transaction Security Protection

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.

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.

Robinhood, MetaMask, and other institutions jointly launched the On-Chain Trading Coordination Protocol (OTL).

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.

Cash App now supports USDC stablecoin transactions on Ethereum and other networks

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 to Phased Rollout Stablecoin Payment Feature

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.

Uniswap Governance Proposal Seeks to Extend Protocol Fees to BNB Chain and Polygon, and Fix Celo Cross-Chain Governance Path

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: ZachXBT Reports Security Incident Related to Internal Operational Wallet Private Key Leakage; User Funds and Market Settlement Secure

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. The investigation indicates that a private key leak occurred in a wallet used for internal operations, and the issue is not related to contracts or core infrastructure. Further updates will be provided.Previous report: ZachXBT stated that the Polymarket UMA CTF Adapter contract allegedly came under attack on Polygon, with over $520,000 having been drained.

THORChain Releases Security Incident Update: Losses to Be Absorbed Through Protocol-Owned Liquidity, Attacker Node Fully Slashed

THORChain has released its fourth update regarding the Asgard vault intrusion incident, publishing the ADR028 proposal and opening voting for node operators. The proposal indicates that the protocol will first absorb losses through its Protocol-Owned Liquidity (POL), with the remaining portion to be borne by synthetic asset holders. The exact proportion is still under evaluation. The POL will be reduced to zero as a result, and the proposal suggests allocating a portion of system revenue over time to gradually replenish it. This plan does not involve minting new RUNE, selling RUNE, or diluting holder equity.On the technical side, the GG20 version will be temporarily retained with a patch upgrade. Trading will resume after the vulnerability is fixed and a successful node rotation is completed. A slower, more security-focused release cadence is planned for the future.Regarding the slashing mechanism, unrelated nodes sharing the same vault as the attacker will be protected, while the attacker's node will be fully slashed. The recovered RUNE will be paired with recoverable assets from the affected vault, and any excess RUNE will be burned.Additionally, THORChain has offered a white-hat bounty to the attacker to recover funds. If a portion of the funds is recovered, the recovery plan will be adjusted proportionally. THORChain emphasizes its commitment to remaining neutral and permissionless, stating it will not censor the attacker's swap transactions after trading resumes.Currently, node operators are voting on the overall direction and principles of the proposal. The specific figures in the ADR are indicative and will be adjusted later via the Mimir mechanism. The goal is to restart the network as soon as possible. A "yes" vote means developers can proceed further along this path.
