Decentralized applications, or DApps, have emerged as a transformative force in the digital world since 2020. Built on blockchain technology, these applications are reshaping industries such as finance, gaming, digital ownership, and content creation. From decentralized exchanges to blockchain-based games, DApps offer users greater transparency, control, and security compared to traditional centralized platforms.
This guide explores the core categories of DApps—DeFi, inscriptions, NFT markets, and GameFi—while highlighting top projects in each space. We’ll also examine how modern crypto wallets like OKX Wallet are simplifying access to this growing ecosystem.
DeFi: The Decentralized Finance Revolution
Decentralized Finance (DeFi) is redefining how people interact with financial services. By eliminating intermediaries like banks and brokers, DeFi platforms enable peer-to-peer lending, borrowing, trading, and yield generation—all powered by smart contracts.
One of the most important metrics in DeFi is Total Value Locked (TVL), which measures the amount of user assets deposited across a protocol. A high TVL often indicates strong trust and adoption.
Popular DeFi protocols include:
- Lido: A leading liquid staking solution that allows users to stake Ethereum and Polygon assets while maintaining liquidity.
- Uniswap: An automated market maker (AMM) on Ethereum that enables seamless token swaps without order books.
- Aave: A multi-chain lending platform where users can earn interest on deposits or borrow assets using their crypto as collateral.
- Curve: A specialized decentralized exchange optimized for stablecoin trading, offering low slippage and minimal fees.
These platforms exemplify how DeFi is making financial services more accessible, transparent, and efficient.

Inscriptions: Breaking Blockchain Boundaries
Inscriptions represent a novel use of blockchain for permanently storing data—such as images, text, or code—directly on-chain. Inspired by ancient stone carvings, this innovation allows creators to mint native digital assets without relying on smart contracts.
This technology has opened new pathways for BRC-20 tokens, ASC-20 assets, and other experimental standards built directly on blockchains like Bitcoin and Ethereum.
Notable inscription platforms include:
- OKX Wallet Inscription Marketplace: Supports BRC-20 token trading with strong liquidity and intuitive interface.
- UniSat: A Chrome extension wallet for the Bitcoin ecosystem, enabling storage and trading of BRC-20 tokens.
- Avascriptions: Uses the ASC-20 protocol to offer an easy-to-use environment for deploying and trading inscribed assets.
- Etch Market: A leading Ethscriptions platform supporting tokens, NFTs, and domain names.
Inscriptions are pushing the limits of what blockchains can do, turning them into permanent archives of human expression.
NFT Markets: The New Era of Digital Ownership
Non-fungible tokens (NFTs) have revolutionized how we perceive ownership in the digital realm. Each NFT represents a unique digital item—be it art, music, virtual real estate, or in-game items—and is verifiably scarce and transferable.
NFT marketplaces serve as hubs where creators and collectors connect. Key players in this space include:
- OKX NFT Marketplace: Operates across multiple blockchains including Ethereum, Polygon, BSC, Avalanche C, and Immutable X. With deep ecosystem integration, it offers superior cross-chain functionality and visibility.
- OpenSea: The largest global NFT marketplace, supporting minting, listing, bidding, and auctioning of NFTs.
- Unisat NFT Platform: Community-driven with built-in royalty distribution for creators.
- Blur: An NFT aggregator tailored for professional traders on Ethereum, offering advanced analytics and fast execution.
These platforms empower artists and developers to monetize their work while giving collectors verifiable proof of authenticity.

GameFi: The Blockchain Gaming Revolution
Blockchain gaming—also known as GameFi—merges traditional gameplay with economic incentives. Players truly own their in-game assets (often as NFTs) and can earn cryptocurrency through play-to-earn models.
Key performance indicators like total transaction volume reflect user engagement and in-game economic activity.
Popular GameFi titles include:
- Hamster Kombat: A clicker game on The Open Network (TON), where players manage a virtual crypto exchange. By clicking on a digital hamster CEO, users generate in-game tokens used to upgrade marketing, licenses, talent, and products—boosting passive income over time.
- Catizen: A casual cat-raising game within Telegram’s ecosystem. Players run a cat café, combining pairs of same-level cats to create higher-tier ones. Higher-level cats produce more tokens per second, which can be spent to accelerate progress. The game also includes social elements like referral rewards and diamond redemption.
- xPet: A browser-based pet simulation game on Arbitrum where players earn tokens through various activities.
- Friend.tech: A decentralized social app on Base chain that blends fandom with on-chain speculation. Users buy “KEY” tokens to enter creator rooms. As demand rises, so does the price. Transaction fees are shared between the platform and room owners.
GameFi is not just entertainment—it's a new model for digital economies where players are stakeholders.
Frequently Asked Questions (FAQ)
Q: What exactly is a DApp?
A: A decentralized application (DApp) runs on a blockchain network rather than a central server. It uses smart contracts to automate operations and gives users full control over their data and assets.
Q: Are DApps safe to use?
A: While DApps offer enhanced security through decentralization, they are not immune to risks. Users should verify contract addresses, avoid suspicious links, and use trusted wallet interfaces to prevent phishing attacks.
Q: How do I start using DApps?
A: You need a non-custodial crypto wallet like OKX Wallet. After connecting your wallet to a DApp’s website, you can interact with its features—such as swapping tokens or minting NFTs—directly from your browser.
Q: Can I use one wallet for multiple blockchains?
A: Yes. Modern wallets like OKX Wallet support over 100 chains—including Bitcoin, Ethereum, Solana, TON, Arbitrum, and Avalanche—and automatically detect networks without manual switching.
Q: Why should I use a wallet’s DApp browser instead of searching online?
A: Built-in DApp explorers reduce the risk of landing on fake or malicious sites. They curate verified projects, helping users avoid scams and phishing attempts.
Q: Is it possible to earn income from DApps?
A: Absolutely. Many DApps offer yield farming (DeFi), play-to-earn rewards (GameFi), or creator royalties (NFTs), allowing users to generate passive or active income in crypto.
