USDC stablecoin issuer Circle has rolled out the public testnet for its payments-focused blockchain network. The company said on Tuesday that more than 100 institutions, including Visa, HSBC, BlackRock, and AI firm Anthropic, are already participating in the testing phase. The testnet will allow developers, financial institutions, and enterprises to deploy, test, and build applications on Arc, which Circle calls an “Economic OS” for the internet. Unveiled in August as an open Layer 1 network, Arc is designed to support developers and companies seeking to bring real-world financial activity on-chain. Circle said the blockchain’s purpose is to facilitate scalable, globally distributed economic activity across borders. The firm described Arc as a system capable of connecting every local market to the global digital economy. Star-Studded Lineup According to the official press release, the early ecosystem already includes organizations from across major regions such as the Americas, Asia, Europe, Africa, and the Middle East. Participants in the testnet collectively manage trillions of dollars in assets and facilitate billions of transactions daily. Circle aims to position Arc as a foundation for stablecoin issuers and tokenized assets such as equities, credit, and money market funds. The firm also plans to use stablecoins as gas tokens on Arc and build native infrastructure for stablecoin swaps and foreign exchange liquidity. Stablecoin issuers from several regions are already joining the testnet, including Forte Securities (AUDF in Australia), Avenia (BRLA in Brazil), JPYC Inc. (JPYC in Japan), BDACS (KRW1 in Korea), Juno (MXNB in Mexico), Coins.PH (PHPC in the Philippines), and Stablecorp (QCAD in Canada). Circle added that it is in discussions with additional issuers of dollar-, euro-, and other fiat-backed stablecoins to expand Arc’s network. The testnet is also drawing interest from developer platforms and blockchain infrastructure providers. Participants include Alchemy, Chainlink, LayerZero, and thirdweb, alongside cross-chain protocols such as Across, Stargate, and Wormhole. Wallet and infrastructure partners include MetaMask, Fireblocks, Ledger, QuickNode, and Blockdaemon, who are helping make Arc accessible to both institutional and retail users. Major market participants in decentralized finance are also testing Arc’s capabilities. Protocols such as Uniswap Labs, Aave, Curve, and Euler Finance are integrating liquidity and lending tools, while centralized exchanges, including Coinbase, Kraken, and Robinhood, are exploring connectivity. The company said market makers such as GSR, Wintermute, Galaxy Digital, and Cumberland are also contributing liquidity support. Beyond digital asset trading, Circle is engaging with global payments and fintech firms to expand Arc’s real-world use cases. Companies like Mastercard, Visa, WorldPay, Brex, Nuvei, and Amazon Web Services are part of the testnet phase. Capital market firms, including Apollo, BNY Mellon, the New York Stock Exchange, and State Street, are also involved. Banks and asset managers participating include Deutsche Bank, HSBC, Goldman Sachs, Standard Chartered, Invesco, and BlackRock. Distributed Governance While Circle is overseeing the initial phase, the company plans for Arc to eventually be operated by a global set of participants, including financial institutions, technology firms, and developers. The roadmap includes expanding validator participation, building transparent governance frameworks, and enabling community input. The long-term goal is for Arc to function as an open, neutral, and collectively managed layer of economic infrastructure for the internet. The latest follows its public listing in June 2025, when the company raised $1.1 billion and achieved a $6.9 billion valuation.

Aave, the largest lending protocol in the DeFi space, is preparing to change how money flows in DeFi with its upcoming V4. The latest version of Aave creates a system where all deposited funds can be shared across different lending markets, a liquidity structure its developers describe as “DeFi’s operating system.”In the latest research note from Aave’s developers, they explained that the V4 upgrade, which is reportedly scheduled for Q4, introduces a modular "hub-and-spoke" architecture, where "Hubs" centralize liquidity, while "Spokes" are specialized lending markets that connect to these Hubs. Each Spoke can implement its own lending rules and risk parameters, allowing for customized borrowing and lending experiences, the developers wrote. “This approach empowers the broader DeFi community to build on Aave rather than competing with it. Service providers and integrators can create specialized experiences while accessing deep liquidity, expanding innovation within the Aave ecosystem rather than fragmenting it across separate markets,” the article reads.To continue reading this as well as other DeFi and Web3 news, visit us at thedefiant.io

Introduction to Altcoin Trading Altcoins are any cryptocurrencies besides Bitcoin. Over the past decade the crypto ecosystem has exploded from a handful of coins to thousands, each trying to solve a specific problem—whether it’s enabling smart contracts (Ethereum), providing fast, low‑fee payments (Solana, Litecoin), powering decentralized finance (Uniswap, Aave), supporting NFTs and gaming (Axie Infinity, Decentraland), or offering privacy (Monero, Zcash). Because many of these projects are still early in their development cycles, their market prices tend to be more volatile than Bitcoin. That volatility creates opportunities for traders who can correctly anticipate short‑term price moves, but it also brings heightened risk of rapid losses. Key concepts to grasp before diving in: Market Capitalization & Liquidity – Larger caps (top 20) usually have tighter spreads and deeper order books, making it easier to enter and exit positions without slippage. Smaller caps can move dramatically on modest trade volumes, which can be attractive for speculative gains but also risky. Tokenomics – Understand the supply model (fixed vs. inflationary), distribution schedule (vesting, staking rewards) and utility of the token. Sudden token releases or protocol upgrades often trigger price spikes or drops. Fundamental Drivers – Project roadmaps, partnership announcements, regulatory news, and community sentiment (Twitter, Reddit, Discord) heavily influence altcoin price dynamics. Technical Analysis Basics – Trend lines, support/resistance zones, moving averages, RSI and MACD are commonly applied to altcoin charts. Given the higher noise, combining several indicators and confirming with volume can improve signal reliability. Risk Management – Set stop‑loss levels, limit leverage, and allocate only a small portion of your portfolio to any single altcoin. Diversification across several projects can smooth out the impact of a single coin’s failure. Regulatory Landscape – Some jurisdictions treat certain altcoins as securities, which can affect exchange listings and legal exposure. Stay informed about the regulatory status of the tokens you trade. By mastering these fundamentals—understanding what each altcoin aims to achieve, how its market behaves, and how to protect capital—you’ll be better equipped to navigate the fast‑paced world of altcoin trading. 1. Why Altcoins Matter Altcoins—cryptocurrencies other than Bitcoin—represent the bulk of the crypto ecosystem. They range from established projects like Ethereum, Solana and Cardano to newer tokens that aim to solve niche problems such as decentralized finance, gaming, or supply‑chain tracking. For many traders, altcoins offer higher volatility than Bitcoin, which can translate into larger short‑term price swings and, consequently, bigger profit opportunities—provided the trader understands the added risk. 2. How Nueva Wealth Handles Altcoins Nueva Wealth treats every cryptocurrency it lists as a CFD (contract‑for‑difference). When you open an altcoin position, you are not buying the token itself; you are speculating on its price movement relative to a fiat or stablecoin denominator. The platform currently offers a curated selection of altcoins, typically the top‑20 by market capitalization, plus a few emerging projects that meet its internal liquidity standards. Key characteristics of the altcoin CFD offering: Fixed spreads – The bid‑ask spread is set in advance and does not change with order size. During periods of extreme market stress, the spread may widen, which can affect entry and exit prices. Leverage options – Most altcoins are available with up to 1:10 leverage. This means a $100 margin can control a $1,000 notional position, magnifying both gains and losses. No token custody – Because the contracts are settled in fiat or a stablecoin, you never receive the underlying altcoin in a wallet. This eliminates concerns about private‑key management but also means you cannot use the token for staking, governance voting, or other on‑chain utilities. Overnight financing – Holding a leveraged altcoin position past the daily settlement window incurs a financing charge calculated on the notional value of the contract. 3. Advantages for Altcoin Traders Speed of Execution – Order latency is measured in sub‑seconds, which is valuable when trading fast‑moving altcoins where price changes can happen in milliseconds. Unified Dashboard – Altcoins sit alongside forex, stocks and commodities, allowing you to shift capital between asset classes without leaving the app. Risk Management Tools – Stop‑loss and trailing‑stop orders are available for each altcoin CFD, giving you a way to limit downside exposure. No Custodial Hassles – Since you never hold the actual token, you avoid the complexities of securing private keys, managing wallets, or dealing with network congestion when transferring coins. 4. Limitations and Risks Lack of Ownership – Without holding the real token, you cannot benefit from airdrops, staking rewards, or governance participation that many altcoin projects offer. Leverage‑Induced Volatility – Altcoins already exhibit high price swings; adding leverage can quickly erode a margin balance if the market moves against you. Liquidity Constraints – While Nueva Wealth selects altcoins with sufficient liquidity, the CFD market depth can be thinner than the spot market on major exchanges. Slippage may occur on large orders. Regulatory Ambiguity – Operating under an offshore licence, the platform does not fall under EU or UK investor‑protection regimes. In the event of insolvency, there is no statutory compensation for deposited funds. Limited Educational Content – The platform’s built‑in learning resources cover basic CFD concepts but do not delve deeply into altcoin fundamentals, tokenomics, or project‑specific risk factors. Traders need to conduct independent research. 5. Practical Tips for Using Nueva Wealth with Altcoins Start Small – Allocate only a modest portion of your capital (e.g., ≤ 10 %) to leveraged altcoin positions until you become comfortable with the platform’s execution and fee structure. Set Protective Stops – Use stop‑loss orders at a level that reflects the altcoin’s typical volatility; consider a trailing‑stop to lock in gains if the price moves favorably. Monitor Financing Costs – If you plan to hold a position overnight, calculate the daily financing charge and factor it into your profitability analysis. Cross‑Check Liquidity – Before entering a sizable trade, compare the quoted spread on Nueva Wealth with spot market spreads on major exchanges (e.g., Binance, Coinbase). A significantly wider spread may indicate lower CFD liquidity. Do Independent Research – Review the altcoin’s whitepaper, roadmap, developer activity, and community sentiment. CFD exposure does not replace the need for fundamental analysis. 6. Frequently Asked Questions Specific to Altcoins Do I earn staking rewards on altcoins traded through Nueva Wealth?No. Because the contracts are settled in fiat or stablecoins, you do not hold the actual token and therefore cannot participate in staking or delegation programs. Can I trade any altcoin I want?Only the altcoins that Nueva Wealth lists are available as CFDs. The selection is limited to assets that meet the platform’s liquidity and compliance criteria. What happens if an altcoin gets delisted on the spot market?If the underlying token is removed from major exchanges, Nueva Wealth may suspend CFD trading for that asset. Existing positions could be closed automatically, and any resulting profit or loss would be settled in fiat. Are there any tax implications specific to CFD altcoin trading?Tax treatment varies by jurisdiction. Generally, CFD profits are considered capital gains or income, depending on local law. Because you never own the token, you do not report a “crypto acquisition” event, but you do need to declare realized gains or losses from CFD closures. Consult a tax professional for guidance. 7. Verdict – Is Nueva Wealth Good for Altcoin Trading? Nueva Wealth offers a fast, mobile‑friendly environment that makes it easy to speculate on a curated list of altcoins. Its strengths lie in rapid order execution, built‑in risk‑management tools and the convenience of handling multiple asset classes from a single interface. For experienced traders who are comfortable with leveraged speculation, understand the risks of CFD products, and are primarily interested in short‑term price movements, Nueva Wealth can be a suitable venue for altcoin exposure. For newcomers or those who wish to hold altcoins long‑term, earn staking rewards, or rely on regulatory protections, a traditional spot exchange or a regulated broker that offers direct token custody may be a better fit. Ultimately, the decision hinges on your trading objectives, risk tolerance, and willingness to supplement the platform’s limited educational content with independent research. If you choose to proceed, start with a small allocation, use protective stops, and keep a close eye on financing costs and liquidity conditions.
