Security & Best Practices

Honeypots on Base and L2 Chains (Complete Guide) Honeypots on Base and L2 Chains are evolving fast: scammers are no longer relying only on classic “can’t sell” tokens. On rollups and L2 ecosystems, the trap can be hidden in gas estimation behavior, router tricks, sequencer timing, MEV-style execution games, and upgradeable control planes that let […]

What Is MEV? (Complete Guide) What Is MEV? MEV is the value that can be extracted from transaction ordering, inclusion, and censorship in a block. If you have ever seen a swap execute at a worse price than expected, watched a liquidation happen “just before” your transaction, or noticed sudden slippage spikes in busy markets,

Gas Estimation Failures as Honeypot Signals (Complete Guide) Gas Estimation Failures as Honeypot Signals is one of the most useful “pre-trade” heuristics in DeFi. When wallets or routers cannot simulate a swap, the failure is often a clue that the token is enforcing hidden restrictions. This guide breaks down what gas estimation really does, why

Reentrancy vs Flash Exploit (Complete Guide) Reentrancy vs Flash Exploit is a confusion that keeps showing up in post-mortems, incident threads, and even audits. Reentrancy is a control-flow problem that lets an attacker re-enter code paths before state is finalized. Flash exploits are a capital and composability problem: the attacker temporarily borrows liquidity, concentrates power

Anti-Bot Features vs Malicious Transfer Restrictions (Complete Guide) Anti-Bot Features vs Malicious Transfer Restrictions is one of the most important distinctions in token safety. Some contracts add guardrails to reduce MEV, snipers, and launch chaos. Others copy the same language and bury a trap: transfers that look normal until buyers try to sell, move, or

What Is a Crypto Honeypot? Technical Breakdown With Code Examples (Complete Guide) What Is a Crypto Honeypot? Technical Breakdown With Code Examples is not just a beginner question. A modern honeypot is often engineered to look normal in the UI while the sell path fails at the contract level. This guide breaks down the exact

Smart Contract Role-Based Access Control (Complete Guide) Smart Contract Role-Based Access Control is the difference between a protocol that can be safely upgraded and operated, and a protocol that quietly hands attackers a steering wheel. This guide breaks down real RBAC patterns used in production, how role hierarchies work, where teams accidentally create backdoors, and

Hidden Admin Roles That Re-Enable Mint (Complete Guide) Hidden Admin Roles That Re-Enable Mint is one of the most misunderstood token risks because the contract can look clean at first glance. People check whether the token has a mint function today, then stop. The real danger is the control surface that can bring minting back

How to Verify Mint Revocation on Ethereum (Complete Guide) How to Verify Mint Revocation on Ethereum is one of the highest ROI checks you can do before buying or integrating a token. If minting power is still active, supply can expand, price can be diluted, and the token’s risk profile changes overnight. This guide shows

Blockchain Operational Security: Supply Chain Security Explained, Detection Signals, and Mitigations Blockchain Operational Security is the difference between “our protocol is audited” and “our users are actually safe in production”. Supply chain compromise is the quiet failure mode that bypasses audits, bypasses best practices, and lands straight in production through build tools, dependencies, CI runners,
