DeFi Bullshit Detector: Red Flags With Claude

The DeFi Bullshit Detector is a Claude instance dedicated to DeFi research, set up to check a protocol’s marketing against onchain reality. In the Arena this week, I tried something different: instead of doing things onchain as usual, I wanted to show how to set one up, and the results were impressive. In 1h15, we were able to setup a new Claude instance from scratch, have it write its claude.md file with our instructions, install the necessary tools to query onchain data, and perform a test analysis on ThGold which returned many critical red flags, several of which were not previously discovered by another researcher as far as I could see.

Why Polaris? The Stablecoin we needed to build

Stablecoins have won: they’re the backbone of DeFi liquidity, the unit of account for onchain trades, and the most outward-facing DeFi usecase. By every adoption metric, they’re the most successful primitive we’ve built. And yet, something went wrong. The dominant stablecoin models have drifted from their original promises. What started as experiments in decentralized money has quietly become a collection of TradFi dependencies wrapped in smart-contract aesthetics. The foundations deteriorated as the TVL climbed. The most popular Stablecoins remain tokenized T-Bills that do not forward their yield, namely USDC and USDT.

veNFTs: Autopilot, 40Acres and haiVELO

The landscape of veNFTs is rapidly evolving, ushering in a new era of decentralized finance where governance power and yield generation are tokenized. As the adoption of the veNFT model grew, the infrastructure supporting it matured, harnessing veNFT’s native yield to deliver novel services and automations. In this article I want to spotlight a few of these: Autopilot, 40Acres & haiVELO. You can refer to my previous articles if you are not already familiar with the veNFT model:
