&lt;/h3&gt;&lt;p&gt;A multi-chain lending protocol operating across Ethereum, Arbitrum, Polygon, and Solana. InfiniLend uses native cross-chain messaging instead of traditional bridges, reducing security risks while offering competitive yields. It surpassed $500 million in TVL within its first month.&lt;/p&gt;</description></item><item><title>DeFi Summer 2026 Trends: Next-Gen Protocols and Projects to Watch</title><link>https://mainnet.jp/en/web3-altcoin/defi-summer-2026-trends/</link><pubDate>Tue, 30 Jun 2026 13:30:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/defi-summer-2026-trends/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/defi-summer-2026-trends-en.png" alt="Featured image of post DeFi Summer 2026 Trends: Next-Gen Protocols and Projects to Watch" /&gt;&lt;p&gt;Decentralized finance continues to evolve at a rapid pace. As of summer 2026, the DeFi landscape has entered a new phase driven by Layer 2 adoption, intent-based architectures, and real-world asset tokenization. This article covers the major trends and noteworthy projects shaping the DeFi space this season.&lt;/p&gt;
&lt;hr&gt;
&lt;h2 id="trend-1-intent-based-protocols"&gt;Trend 1: Intent-Based Protocols
&lt;/h2&gt;&lt;p&gt;Traditional DeFi requires users to specify every transaction detail. The 2026 shift toward &amp;ldquo;intent-based&amp;rdquo; protocols changes this paradigm. Users simply express their intent, such as &amp;ldquo;swap USDC for ETH,&amp;rdquo; and solvers compete to find the optimal route and rate. This dramatically improves user experience and automatically optimizes gas costs.&lt;/p&gt;</description></item><item><title>Role of Layer 2 (Arbitrum, Optimism etc.) and Gas Fee Savings</title><link>https://mainnet.jp/en/web3-altcoin/layer-2-arbitrum-optimism-gas-savings/</link><pubDate>Tue, 16 Jun 2026 14:20:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/layer-2-arbitrum-optimism-gas-savings/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/layer-2-arbitrum-optimism-gas-savings-en.png" alt="Featured image of post Role of Layer 2 (Arbitrum, Optimism etc.) and Gas Fee Savings" /&gt;&lt;p&gt;As users on Ethereum multiply, the network faces high gas fees and slow transactions. The leading technology engineered to solve this scaling bottleneck is &amp;ldquo;Layer 2&amp;rdquo; (L2). We examine L2 networks like Arbitrum and Optimism and check how they cut fees.&lt;/p&gt;
&lt;h2 id="ethereums-scaling-bottleneck"&gt;Ethereum&amp;rsquo;s Scaling Bottleneck
&lt;/h2&gt;&lt;p&gt;Prioritizing decentralized security, Ethereum&amp;rsquo;s base layer (L1) processes limited transactions per block, causing gas fees to spike to tens of dollars during high traffic.&lt;/p&gt;
&lt;h2 id="the-layer-2-architecture"&gt;The Layer 2 Architecture
&lt;/h2&gt;&lt;p&gt;L2 networks process transaction logs off the Ethereum main chain, roll them up into batches, and post only compressed proofs back to L1 (via Rollup technology).&lt;/p&gt;</description></item><item><title>What is a Smart Contract?

Learning Ethereum's Innovation" /&gt;&lt;p&gt;While Bitcoin operates as peer-to-peer electronic money, Ethereum&amp;rsquo;s breakthrough was introducing &amp;ldquo;Smart Contracts.&amp;rdquo; We explain how this automated contract technology works and examine the innovations it enables.&lt;/p&gt;
&lt;h2 id="what-is-a-smart-contract"&gt;What is a Smart Contract?
&lt;/h2&gt;&lt;p&gt;A smart contract is a self-executing software program running on public ledgers that enforces logic rules: &amp;ldquo;If X condition is met, automatically execute Y action.&amp;rdquo;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Everyday Analogy: Vending Machines&lt;/strong&gt;: Inserting coins and pressing a button (Condition) triggers the release of a drink (Action) without a human salesperson.&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="the-blockchain-edge"&gt;The Blockchain Edge
&lt;/h2&gt;&lt;p&gt;Running these agreements on decentralized chains generates massive efficiency gains:&lt;/p&gt;</description></item><item><title>How to Create Web3 Wallets (MetaMask etc.) and Secure Connection</title><link>https://mainnet.jp/en/web3-altcoin/create-web3-wallet-metamask-secure-connection/</link><pubDate>Fri, 05 Jun 2026 14:15:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/create-web3-wallet-metamask-secure-connection/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/create-web3-wallet-metamask-secure-connection-en.png" alt="Featured image of post How to Create Web3 Wallets (MetaMask etc.) and Secure Connection" /&gt;&lt;p&gt;To buy NFTs or interact with DeFi, owning a Web3 wallet like MetaMask is mandatory. It acts as both your bank vault and your digital passport. We provide a step-by-step tutorial on setting up MetaMask and maintaining wallet safety.&lt;/p&gt;
&lt;h2 id="what-is-metamask"&gt;What is MetaMask?
&lt;/h2&gt;&lt;p&gt;A software cryptocurrency wallet and browser extension designed to store Ethereum-compatible tokens and sign smart contract transactions.&lt;/p&gt;

Evolution from Digital Art to Utility</title><link>https://mainnet.jp/en/web3-altcoin/what-is-nft-evolution-utility/</link><pubDate>Wed, 03 Jun 2026 14:00:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/what-is-nft-evolution-utility/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/what-is-nft-evolution-utility-en.png" alt="Featured image of post What is NFT? Evolution from Digital Art to Utility" /&gt;&lt;p&gt;NFTs (Non-Fungible Tokens) grant proof of ownership to digital files. While the initial boom focused on highly valued digital artwork, NFTs are evolving from simple images into digital membership keys featuring real-world utility.&lt;/p&gt;
&lt;h2 id="how-nfts-work"&gt;How NFTs Work
&lt;/h2&gt;&lt;p&gt;By tracking ownership histories on decentralised ledgers, NFTs establish scarcity for digital objects, proving authenticity in a copy-paste digital world.&lt;/p&gt;
&lt;h2 id="the-utility-nft-shift"&gt;The Utility NFT Shift
&lt;/h2&gt;&lt;p&gt;Rather than static art, utility NFTs unlock experiences, discounts, or digital privileges for cardholders.&lt;/p&gt;</description></item><item><title>Mechanism of DApps (Decentralized Apps) and Representative Services</title><link>https://mainnet.jp/en/web3-altcoin/dapps-mechanisms-representative-services/</link><pubDate>Wed, 25 Feb 2026 14:05:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/dapps-mechanisms-representative-services/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/dapps-mechanisms-representative-services-en.png" alt="Featured image of post Mechanism of DApps (Decentralized Apps) and Representative Services" /&gt;&lt;p&gt;DApps (Decentralized Applications) are the backbone of Web3. Unlike traditional web services (like Twitter or YouTube) run by corporations, DApps run autonomously on decentralized blockchain networks. We explain their mechanisms.&lt;/p&gt;
&lt;h2 id="core-features-of-dapps"&gt;Core Features of DApps
&lt;/h2&gt;&lt;h3 id="1-absence-of-central-control"&gt;1. Absence of Central Control
&lt;/h3&gt;&lt;p&gt;Codebases and smart contracts are open-source. Apps cannot be shut down arbitrarily due to corporate insolvency.&lt;/p&gt;
&lt;h3 id="2-no-sign-up--login-friction"&gt;2. No Sign-up / Login Friction
&lt;/h3&gt;&lt;p&gt;Instead of registering emails and personal data, users unlock services simply by connecting a Web3 wallet.&lt;/p&gt;</description></item><item><title>How to Choose Altcoins: Analytical Methods for High-Potential Projects</title><link>https://mainnet.jp/en/web3-altcoin/how-to-choose-altcoins-analytical-methods/</link><pubDate>Tue, 20 Jan 2026 13:50:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/how-to-choose-altcoins-analytical-methods/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/how-to-choose-altcoins-analytical-methods-en.png" alt="Featured image of post How to Choose Altcoins: Analytical Methods for High-Potential Projects" /&gt;&lt;p&gt;&amp;ldquo;Altcoins&amp;rdquo; refer to any cryptocurrency other than Bitcoin. With thousands of options in the market, locating high-potential projects requires a structured evaluation framework. We explain fundamental altcoin research steps.&lt;/p&gt;
&lt;h2 id="4-pillars-of-altcoin-analysis"&gt;4 Pillars of Altcoin Analysis
&lt;/h2&gt;&lt;h3 id="1-whitepaper-and-utility"&gt;1. Whitepaper and Utility
&lt;/h3&gt;&lt;p&gt;Inspect what technical or financial problems the project attempts to solve. Coins lacking real-world utilities dry up once hype declines.&lt;/p&gt;

New Organization Style" /&gt;&lt;p&gt;DAO (Decentralized Autonomous Organization) represents a major paradigm shift in human coordination. Bypassing corporate boardrooms, DAOs are coordinated via blockchain programs and token holder votes. We explain how DAOs work.&lt;/p&gt;
&lt;h2 id="3-core-characteristics-of-a-dao"&gt;3 Core Characteristics of a DAO
&lt;/h2&gt;&lt;h3 id="1-flat-governance"&gt;1. Flat Governance
&lt;/h3&gt;&lt;p&gt;Lacks corporate executive directors. Direction is dictated by suggestions and votes submitted by holders of the DAO&amp;rsquo;s governance token.&lt;/p&gt;
&lt;h3 id="2-full-treasury-transparency"&gt;2. Full Treasury Transparency
&lt;/h3&gt;&lt;p&gt;Financial reserves (treasury wallets) and voting data are publicly stored on-chain, rendering backroom deals impossible.&lt;/p&gt;</description></item><item><title>Steps and Precautions to Earn Free Tokens via Airdrops</title><link>https://mainnet.jp/en/web3-altcoin/earn-free-tokens-airdrops-steps-precautions/</link><pubDate>Mon, 12 Jan 2026 14:35:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/earn-free-tokens-airdrops-steps-precautions/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/earn-free-tokens-airdrops-steps-precautions-en.png" alt="Featured image of post Steps and Precautions to Earn Free Tokens via Airdrops" /&gt;&lt;p&gt;Web3 projects often reward early users by distributing free tokens via &amp;ldquo;Airdrops.&amp;rdquo; While highly lucrative, often yielding thousands of dollars, the field is rife with malicious actors. We outline the mechanics and safety rules.&lt;/p&gt;
&lt;h2 id="why-projects-host-airdrops"&gt;Why Projects Host Airdrops
&lt;/h2&gt;&lt;p&gt;Early projects launch token rewards to:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Reward early beta testers and boost app engagement metric targets.&lt;/li&gt;
&lt;li&gt;Distribute governance tokens to community nodes, completing the shift to a DAO.&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="standard-engagement-tasks"&gt;Standard Engagement Tasks
&lt;/h2&gt;&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Testing Betas&lt;/strong&gt;: Connecting wallets to trial early software features.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Liquidity Provision&lt;/strong&gt;: Staking assets in pools to help establish asset depth.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Social Marketing Tasks&lt;/strong&gt;: Submitting verification logs after joining community channels.&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="crucial-airdrop-scam-countermeasures"&gt;Crucial Airdrop Scam Countermeasures
&lt;/h2&gt;&lt;p&gt;Beware of fake Twitter accounts announcing &amp;ldquo;Airdrop Claim is Live!&amp;rdquo; Connecting MetaMask to fake sites prompts signature calls that steal all your tokens. Rely strictly on links posted inside &lt;strong&gt;verified official Discord channels&lt;/strong&gt;.&lt;/p&gt;</description></item><item><title>The Future of Metaverse and Blockchain Games (Play to Earn)</title><link>https://mainnet.jp/en/web3-altcoin/metaverse-blockchain-games-play-to-earn-future/</link><pubDate>Fri, 09 Jan 2026 14:25:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/metaverse-blockchain-games-play-to-earn-future/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/metaverse-blockchain-games-play-to-earn-future-en.png" alt="Featured image of post The Future of Metaverse and Blockchain Games (Play to Earn)" /&gt;&lt;p&gt;The idea of making a living by playing video games, once a pipe dream, has materialized via Play-to-Earn (P2E) blockchain gaming. We explain the token economy models behind Web3 games and analyze the outlook of the industry.&lt;/p&gt;
&lt;h2 id="how-play-to-earn-works"&gt;How Play-to-Earn Works
&lt;/h2&gt;&lt;p&gt;In legacy games, gold coins or items have zero external value and disappear if the game shuts down.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Tokenized In-Game Items&lt;/strong&gt;: Porting items to blockchain NFTs secures true player ownership.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Organic In-Game Economies&lt;/strong&gt;: Earned tokens can be swapped for stablecoins or fiat currencies on open DEX marketplaces.&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="merging-blockchains-with-the-metaverse"&gt;Merging Blockchains with the Metaverse
&lt;/h2&gt;&lt;p&gt;Virtual plots of land or shops inside virtual spaces (like The Sandbox or Decentraland) are traded as NFTs, fueling virtual commercial businesses.&lt;/p&gt;</description></item><item><title>Basics of DeFi (Decentralized Finance) and How to Start Yield Farming</title><link>https://mainnet.jp/en/web3-altcoin/defi-basics-yield-farming-beginners/</link><pubDate>Sun, 04 Jan 2026 13:55:00 +0900</pubDate><guid>https://mainnet.jp/en/web3-altcoin/defi-basics-yield-farming-beginners/</guid><description>&lt;img src="https://mainnet.jp/img/thumbnail/defi-basics-yield-farming-beginners-en.png" alt="Featured image of post Basics of DeFi (Decentralized Finance) and How to Start Yield Farming" /&gt;&lt;p&gt;Operating via smart contracts, DeFi (Decentralized Finance) eliminates banks and traditional intermediaries. &amp;ldquo;Yield Farming&amp;rdquo; (liquidity mining) allows investors to generate high interest rates. We review the basics and setup steps for beginners.&lt;/p&gt;
&lt;h2 id="what-is-defi"&gt;What is DeFi?
&lt;/h2&gt;&lt;p&gt;DeFi refers to software-run financial systems on public blockchains. Removing banks cuts operational margins, letting users capture yields far exceeding typical savings account rates.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Key Services&lt;/strong&gt;: Uniswap (Decentralized Exchange), Aave (Lending Portal).&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="mechanics-of-yield-farming"&gt;Mechanics of Yield Farming
&lt;/h2&gt;&lt;p&gt;Providing a pair of crypto assets (e.g. ETH and USDC) to liquidity pools on decentralized exchanges (DEXs). In return, you earn swap fees and newly minted incentive tokens.&lt;/p&gt;</description></item></channel></rss>
