A coordinated multi‑chain attack on the Wasabi Protocol on April 30, 2026 stole roughly $5‑$5.5 million, moved the assets across Ethereum, Base, Berachain and Blast, and ultimately laundered the entire amount through Tornado Cash, highlighting critical key‑management failures in DeFi.
In April 2026, the DeFi liquid staking protocol KelpDAO lost roughly $290 million worth of rsETH after a sophisticated attack by the Lazarus Group that combined RPC node poisoning with a DDoS on the LayerZero Decentralized Verifier Network, prompting emergency measures across major lending platforms.
This comprehensive analysis explains how stablecoins—digital assets pegged to fiat currencies—operate through minting, burning, and reserve management, compares different models such as fiat‑backed, crypto‑backed, and algorithmic designs, examines their role in DeFi and cross‑border payments, and discusses regulatory trends shaping their evolution.
This comprehensive glossary presents 219 of the hottest Web3, blockchain, DeFi, stablecoin and exchange concepts, offering clear definitions, key characteristics and illustrative images to help readers quickly master the essential terminology shaping the future of digital finance.
This article builds a comprehensive Web3 knowledge framework, tracing the paradigm shift from Web2’s data‑centric models to a decentralized ecosystem where blockchain, cryptography, and token economics empower users with true data ownership, new financial primitives, cross‑chain infrastructure, and a reimagined payment landscape.
The article analyzes why Web3’s immutable, code‑as‑law nature forces a shift from traditional post‑deployment audits to continuous DevSecOps practices, and extends this security imperative to other high‑risk sectors such as critical infrastructure, aerospace, and medical devices.
This article explains the concept of Ticks in Uniswap V3, detailing how they discretize price ranges, enable concentrated liquidity, affect gas costs through tick spacing, and impact both liquidity providers and traders in the DeFi ecosystem.
Explore the intricate architecture of Uniswap V3 by dissecting its core contracts—v3-core and v3-periphery—covering factories, pools, callbacks, interface definitions, state variables, and practical learning steps, revealing how its modular design underpins modern DeFi security and flexibility.
This guide explains why accessing on‑chain data directly is the most trustless method, outlines the steps to query a Uniswap V3 ETH/USDC pool using Web3.py, provides full Python code, and offers practical tips for extending the approach to other pools and historical data.
This article examines the technical evolution from traditional order‑book decentralized exchanges to automated market makers, comparing their mechanisms, advantages, challenges, and the emerging hybrid models that shape the future of DeFi liquidity.
This article breaks down the technical foundations of DeFi, explaining how smart contracts enable decentralized exchanges, comparing order‑book and automated market‑maker architectures, and detailing supporting components such as oracles, stablecoins, and lending protocols with concrete examples and formulas.
Running a decentralized exchange requires extensive pre‑launch development, rigorous security audits, robust front‑end design, tokenomics planning, and continuous post‑launch operations such as infrastructure maintenance, security monitoring, liquidity management, and community governance.
This article explains how decentralized exchanges use a constant‑product AMM model that makes prices slide, why users must set slippage tolerance, and how MEV sandwich attacks exploit that tolerance to extract value.
This article walks you through a real DeFi transaction on Etherscan, explaining each field, event log, and the underlying smart‑contract interactions so you can confidently interpret blockchain activity without feeling overwhelmed.
Stablecoins, crypto assets pegged to real-world values, are rapidly expanding in 2025, offering low‑cost payments, investment safety, and a foundation for DeFi, while reshaping global finance through increased inclusion, regulatory scrutiny, institutional adoption, and emerging technological innovations.
The article reviews the rapid rise of Web3, outlines the severe security challenges and economic losses caused by attacks on cross‑chain bridges, DeFi platforms, and smart contracts, and details Ant Group's Sky Dome Lab research on platform, contract, and client‑side defenses along with future AI‑driven initiatives.
This article examines the multi‑stage Tornado Cash governance attack, explaining the proposal mechanism, token‑locking logic, creation of zombie accounts, use of create/create2, malicious self‑destruct functions, delegatecall exploitation, and the resulting token theft, while highlighting key security lessons for blockchain governance.
This article explains the main characteristics of Web 3.0, including its decentralized architecture, blockchain foundations, semantic web, AI integration, DeFi, ubiquitous access, and 3‑D graphics, highlighting how these innovations differentiate it from earlier web generations and improve user privacy and experience.
