Testnet faucets distribute valueless test tokens so you can run transactions without spending real money. This post covers which faucets work for Sepolia and other networks, why they have restrictions, and what to do when they're empty.

Testing a transaction isn't one thing — it's three distinct techniques for three different risks. This post breaks down test sends, testnets, and transaction simulation, and what each one actually protects against.

Backing up a wallet means more than writing down the seed phrase. A complete backup covers the seed phrase, any passphrase layered on top, and documentation of account structure — because an incomplete backup can silently leave funds inaccessible.

MetaMask security isn't one problem — it's four distinct problems with different failure modes. This post maps the seed phrase, approval, phishing, and browser layers, and explains what actually changes each risk.

A pump and dump follows a recognizable four-stage pattern: accumulation, trigger, distribution, collapse. This post maps the mechanism, the on-chain signals worth checking, and what distinguishes coordinated manipulation from organic volatility.

Verifying a crypto team is harder than it looks — credentials can be fabricated, investors can be misrepresented, and LinkedIn is not proof of anything. This post maps the verification steps that are actually reliable: GitHub commit history, on-chain vesting, and independent investor confirmation.

Token supply metrics — circulating, total, and max — are frequently misread and sometimes self-reported inaccurately. This post explains each number, how to verify them on-chain, and how to read holder distribution to identify concentration risk.

A token's name tells you nothing — its contract address is the canonical identifier. Here's how to find it, verify it, and why the source you check matters.

Most people research tokens in the wrong order — price first, fundamentals second. This explains the mechanism-first approach: what to check, in what order, and what each check actually tells you.

Most crypto scams fit into two categories — technical exploits and social engineering. Understanding the pattern is more durable than memorizing a growing list of specific threats.

A DeFi bank run plays out through smart contract logic rather than human decisions. Here's what actually happens — step by step — when a lending protocol faces a mass-exit event.
