2 min read

在我们“安全智能合约开发”系列中，我们将深入探讨智能合约开发的关键安全方面，重点关注 NFT 合约。我们探讨了作为开发人员可能遇到的各种风险和漏洞，并提供了详细的策略和最佳实践来缓解这些问题，以增强区块链应用程序的安全性和效率。

详细分解：全面概述

本文探讨了 NFT 合约中的重入漏洞，详细介绍了单函数重入和跨函数重入。它解释了这些漏洞相关的风险，并为开发人员提供了用于保护其智能合约的缓解策略。

数字签名已广泛应用于智能合约，例如在白名单铸造和订单簿 NFT 市场中。这是因为它可以帮助节省交易成本（链下签名和链上验证）。然而，开发人员的误用也会给 NFT 市场带来风险。在本文中，我们将讨论 NFT 生态系统中数字签名的误用。

The Decentralization Dilemma: Cascading Risk and Emergency Power in the KelpDAO Crisis

This BlockSec deep-dive analyzes the KelpDAO $290M rsETH cross-chain bridge exploit (April 18, 2026), attributed to the Lazarus Group, tracing a causal chain across three layers: how a single-point DVN dependency enabled the attack, how DeFi composability cascaded the damage through Aave V3 lending markets to freeze WETH liquidity exceeding $6.7B across Ethereum, Arbitrum, Base, Mantle, and Linea, and how the crisis forced decentralized governance to exercise centralized emergency powers. The article examines three parameters that shaped the cascade's severity (LTV, pool depth, and cross-chain deployment count) and provides an exclusive technical breakdown of Arbitrum Security Council's forced state transition, an atomic contract upgrade that moved 30,766 ETH without the holder's signature.

Weekly Web3 Security Incident Roundup | Apr 13 – Apr 19, 2026

This BlockSec weekly security report covers four attack incidents detected between April 13 and April 19, 2026, across multiple chains such as Ethereum, Unichain, Arbitrum, and NEAR, with total estimated losses of approximately $310M. The highlighted incident is the $290M KelpDAO rsETH bridge exploit, where an attacker poisoned the RPC infrastructure of the sole LayerZero DVN to fabricate a cross-chain message, triggering a cascading WETH freeze across five chains and an Arbitrum Security Council forced state transition that raises questions about the actual trust boundaries of decentralized systems. Other incidents include a $242K MMR proof forgery on Hyperbridge, a $1.5M signed integer abuse on Dango, and an $18.4M circular swap path exploit on Rhea Finance's Burrowland protocol.

Weekly Web3 Security Incident Roundup | Apr 6 – Apr 12, 2026

This BlockSec weekly security report covers four DeFi attack incidents detected between April 6 and April 12, 2026, across Linea, BNB Chain, Arbitrum, Optimism, Avalanche, and Base, with total estimated losses of approximately $928.6K. Notable incidents include a $517K approval-related exploit where a user mistakenly approved a permissionless SquidMulticall contract enabling arbitrary external calls, a $193K business logic flaw in the HB token's reward-settlement logic that allowed direct AMM reserve manipulation, a $165.6K exploit in Denaria's perpetual DEX caused by a rounding asymmetry compounded with an unsafe cast, and a $53K access control issue in XBITVault caused by an initialization-dependent check that failed open. The report provides detailed vulnerability analysis and attack transaction breakdowns for each incident.
