The fourth edition of Coinspect's Wallet Security Ranking evaluates 19 browser extension wallets with new address poisoning coverage, a reproducible testing wizard, and AI-assisted evidence reviews.

How Coinspect traced a wallet-drain investigation back to a twelve-year-old insecure randomness flaw, searched for exposed addresses at scale, and disclosed the findings in stages while attackers were still active.

Coinspect expands the Wallet Security Verification Standard into the Wallet Security Framework, an open-source resource that now combines white-box controls with black-box benchmark tests.

Weak randomness in wallet generation turns impossible-to-brute-force recovery phrases into realistic attacker targets. Updating apps or re-importing seeds does not fix the risk.

Learn EVM Attacks now runs all 40+ exploit reproductions fully offline with an RPC caching layer. No API keys, no archive node. Clone, install Foundry, run.

Four new DeFi exploit reproductions with Solidity PoCs and Foundry tests: Futureswap, 1inch calldata corruption, Bunni rounding bug, LyraDepositWrapper.

Our latest Wallet Security Ranking evaluates 77 wallets, showcasing individual security improvements and revealing that advanced protections are not adopted evenly across platforms.

An attacker exploited a rounding issue in the calculation of the stable swap invariant, deflating the implied BPT price and extracting value via internal balances and a follow-up withdrawal.

Recent supply chain attacks reveal how Web3 faces escalating threats. Vulnerable workflows, stolen tokens, and phishing can expose millions. Here's what's next and how to prepare.

Recent NPM breaches show how fast supply chain attacks spread. Learn how to lock dependencies and harden workflows to before attackers reach your projects.

During the Qix NPM supply chain attack, major dApp frontends nearly shipped wallet-stealing malware. Lockfiles were the safeguard.

Discover how real-world DeFi exploits unfolded across Ethereum, Polygon, BNB Chain, and more with our new Learn EVM Attacks web app. Explore detailed attack reproductions, on-chain analysis, runnable Solidity PoCs, and categorized insights on vulnerabilities like reentrancy, oracle manipulation, and governance exploits—all designed to help auditors, builders, and researchers strengthen smart contract security.

Attackers are registering expired dApp domains, linked from DeFi aggregators and old socials, to trick users into connecting wallets and draining their funds.

The second edition of Coinspect’s Crypto Wallet Security Ranking is live featuring 74 wallet apps across iOS, Android, and browser extensions.

Discover how critical vulnerabilities in browser-based crypto wallets allowed attackers to drain funds without user interaction.

Liquity engaged Coinspect to audit Liquity v2 Governance smart contracts, enhancing decentralized governance with modular initiatives and security measures.

We're excited to release the first results of the Crypto Wallet Security Ranking, our uniquely comprehensive ranking framework for crypto wallet security.

Discover how Coinspect developed the Crypto Wallet Security Ranking to elevate web3 security with scalable, objective wallet evaluations.

Smart contracts are often seen as immutable but the hidden 'God Mode' used by developers can undermine the decentralization promises of blockchain.

Crypto wallet security improvements can block common scams that cost users millions. Discover how secure web3 wallets can protect you from phishing attacks.

Bitcoin Core developers fixed and revealed a high-risk DoS vulnerability allowing attackers to crash 17% of mainnet nodes at a cost of just 0.14 BTC.

Upgradeable smart contracts offer flexibility but introduce security risk. Learn common pitfalls in proxy patterns, storage management, and initialization.

The EUCLEAK attack allows attackers to steal private keys with just minutes of physical access and bypassing crucial secure hardware attestation protocols.

This article explores the mechanics of merged-mining, its security benefits, and the critical vulnerabilities identified by Coinspect in real-world implementations. With a focus on the Bitcoin L2 movement, we offer actionable insights for blockchain designers, developers, and researchers working to build secure, interconnected networks.

Discover how Coinspect collaboration with Babylon have fortified the platform, ensuring a safe and successful launch of their Bitcoin-native staking protocol. Read about our contributions and the future of secure innovation in the Bitcoin L2 ecosystem.

Coinspect conducted comprehensive security reviews of projects built on Soroban, Stellar's new smart contracts platform. Key findings from our audit of the Tricorn Bridge include the identification and resolution of critical vulnerabilities, contributing valuable insights to the Soroban security community.
