Circle has released a "Post-Quantum Security Whitepaper," proposing a phased post-quantum resilience roadmap centered on the long-term security of the Arc blockchain ecosystem.The roadmap covers multiple technical areas, including quantum-safe signatures, private execution environments, validator hardening, infrastructure migration, and account recovery, applicable to core components such as the Arc network, USDC, smart contracts, and validators.Circle stated that it plans to provide post-quantum signature support at the launch of the Arc mainnet (2026) to enhance the ecosystem's ability to withstand future quantum computing threats.
TownSquare, an infrastructure provider for institutional yields and cross-chain lending brokerage services, has partnered with Native, a non-custodial automated trading infrastructure, to launch a $10 million yield-generating vault on the Monad L1. This vault will support assets including USD1, USDC, cbBTC, and MON, offering higher yields than conventional lending through trading-based yield generation. This marks TownSquare’s first collaboration with a trading-based yield manager. The partnership aims to bring real-world asset (RWA) and stablecoin institutional yields to a broader user base. Native is a close partner of Binance Wallet and Buidlpad, having previously launched vaults for BNB and wETH on BNB Chain and Ethereum—demonstrating its stability, scalability, and ability to generate yields for liquidity providers (LPs) managing tens of millions of dollars. This initiative also represents the first trading-yield vault on the Monad chain. Native already operates credit pools across multiple EVM chains with over $35 million in liquidity, achieving daily trading volumes of $50–100 million and cumulative trading volume exceeding $25 billion. Its Proactive Market Making (PMM) structure enables retail users to access institutional-grade trading yields. TownSquare previously launched a $100 million USD1 liquidity program and has raised over $16 million to date—including funding from this collaboration.
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.

decentralized derivatives platform Hyperliquid has launched a pre-listing perpetual contract for SpaceX (SPCX-USDC) via Trade.xyz, sparking controversy over a global regulatory gap. The contract provides leveraged trading without requiring users to hold any SpaceX stock or authorization from the company. Initially priced at $150, corresponding to an implied valuation of approximately $1.78 trillion, the contract surged to $216 shortly after launch.According to reports, the contract is settled in USDC, with prices derived from market oracles and not linked to SpaceX's actual financials or equity structure. SpaceX itself has neither authorized nor participated in this market, yet its valuation is being priced and traded in real-time on-chain, raising concerns that "decentralized derivatives are taking over price discovery for private companies." This market originates from Hyperliquid's HIP-3 mechanism, suggesting that private company valuations may increasingly be re-priced by on-chain derivatives, while regulatory frameworks have yet to establish corresponding standards.

payment infrastructure company MoonPay has launched a dedicated application on ChatGPT Apps, allowing users to generate purchase links within OpenAI's chatbot for buying digital assets such as Bitcoin, XRP, Solana, and USDC. When users specify a purchase amount in ChatGPT, they receive a MoonPay checkout link and are redirected to the MoonPay website to complete KYC, checkout procedures, and connect their wallet. Users who have already completed KYC for their MoonPay account can log in directly via their existing account, use their most recent payment method, and send assets to a designated address. This application is part of MoonPay's push to advance AI-driven crypto tools. Earlier this month, MoonPay acquired AI trading startup Dawn Labs and launched Dawn CLI; the company also recently introduced the MoonAgents Card, a virtual Mastercard that allows AI agents to pay online merchants directly with stablecoins from crypto wallets.

: According to official sources, Aave, MetaMask, and Mastercard are advancing the MetaMask debit card feature, allowing users to directly use yield-bearing assets on Aave, such as mUSD, USDC, wETH, USDT, and other tokens, for everyday spending.This debit card is powered by instant settlement support through Consensys' Ethereum Layer 2 network, Linea. After users deposit mUSD into Aave to receive receipt tokens, the card automatically converts the required amount of yield-bearing assets into fiat currency the moment a transaction is made. During this process, users' unspent balances continue to earn interest through Aave until the exact moment of the transaction, enabling instant spending of yield-bearing assets while maintaining continuous yield. The debit card is currently being rolled out in Europe.
