Qwen2.5-Coder vs DeepSeek-Coder for Solidity Review: What I Actually See Locally
I keep a folder of ten small Solidity contracts with bugs I planted myself: a classic reentrancy in a withdraw function, a missing access modifier on …

Dev Log 07: Mitigating RPC Latency Desyncs During Polygon Hard Forks
Maintaining real-time transaction tracking layers across a multi-tier infrastructure requires seamless node data synchronization. During heavy network…
I ran my Solidity scanner on 6 top-audited DeFi protocols. Every 'critical' was a false positive — here's why.
Most Solidity scanners are high-recall, low-precision. They flag 40 things, 38 are noise, and after the third report you stop reading them — so the on…
Dev Log 06: Designing Reentrancy Guards and State Locks in Staking Pools
When building our live core liquidity tiers ( hNobtStaking and BroilerPlusStaking ) on Polygon Mainnet, preventing transaction-ordering dependencies a…
I'm Entering My First Sherlock Audit Contest: The Setup, the Plan, the Fear
I have shipped software for 18 years. Roughly 8 of those in crypto. And this week I signed up for my first Sherlock audit contest, and my hands were a…
MythX shut down in March and nothing replaced it so I built something
If you were using MythX before March 31st, you already know. ConsenSys quietly sunset the entire MythX suite. One day it was there, the next your CI p…
Shipping a Solidity contract to mainnet? Do this 20-minute self-check first
You built something. Tests pass. You're days from mainnet. Before you either skip security entirely (please don't) or spend weeks lining up a full aud…
I ran my Solidity scanner across the 10 most-audited codebases in web3. Here's every flag.
The dirty secret of automated smart-contract security tools isn't that they miss bugs. It's that they cry wolf. Point a typical static analyzer at a c…
I almost reported a critical bug that didn't exist. One constant saved me.
Last week I was reviewing the staking engine of a protocol before its mainnet launch. Deep in a 1,400-line contract, I found what looked like a seriou…
7 ways to drain an ERC-4626 vault (and how a good protocol closes each one)
Based on real audits of production vaults and AMMs. A tokenized vault (ERC-4626) looks simple: deposit assets, get shares; burn shares, get assets bac…
I built my first Robinhood Chain app as an index basket
I built a small index basket app on Robinhood Chain because I wanted to understand the developer path from the first contract deploy all the way to a …
The Tether Paradox: Shitty ERC-20s, OpenZeppelin, and the Unstoppable Web
I have a confession to make. When I first saw that Tether—the behemoth behind the $110 billion USDT stablecoin—was the primary financial backer of Hol…
Signature Replay Attacks in Solidity: The Bug That Looks Correct
Some smart contract bugs scream at you. A missing onlyOwner , a reentrancy with the state update after the transfer. Signature replay is not one of th…
AgentJobs: Non-Custodial Agent-to-Agent Escrow, Live on Monad
The problem AI agents are starting to hire each other — one agent delegates a sub-task to another, pays for the output, moves on. The blocker isn't ca…
Front-Running and MEV: Writing Contracts That Don't Leak Money to the Mempool
When you submit a transaction, it sits in the public mempool before it is mined, visible to everyone. Bots watch that mempool and reorder, insert, or …
От Кремниевой долины к техно-фашизму: почему облачные LLM — это ловушка, и как я собрал свой локальный ИИ на коленке
Кремниевая долина строит ИИ как оружие. А мы, разработчики, остаёмся без дешёвого ChatGPT. Я не стал ждать — за пару вечеров настроил локальную LLM на…
The Token Is the Least Interesting Part of Tokenization
"Most tokenization discussions stop at the token. In reality, the token is often the simplest component of the entire system." There is a moment that …
Gas Optimization That Doesn't Break Security: Storage, Calldata, and the Traps
Gas optimization is satisfying. You shave a few thousand gas off a function and feel clever. But some optimizations trade away safety in ways that are…
Reentrancy in 2026: Why It Still Drains Millions (and How AI Spots It)
Reentrancy is the oldest trick in smart contract exploitation. The DAO fell to it in 2016. You would think a bug this famous would be extinct by now. …
Access Control Bugs: The #1 Cause of Smart Contract Hacks This Year
Every year the post-mortems pile up, and every year the same category sits at the top of the loss chart. Not reentrancy. Not oracle manipulation. Acce…
Foundry Invariant Testing: Finding Bugs Fuzzing Can't
Your fuzz tests pass. Your unit tests pass. Coverage is green. Then the protocol goes live and someone drains the vault with a five-transaction sequen…
