Introducing coalscan.io I vibecoded a site for Solana trenchers that lets you scan a Solana contract and it returns a coal score (1–100) based on holder patterns and on chain behavior across the top 30 wallets. The goal isn’t to tell you what to buy, it's to help quantify downside risk and see quality metrics all in one spot. I spent the past week fixing the logic in real time while scanning tokens and trading, spotting recurring wallet patterns, and adjusting the weights of each metric. The score is solid, but please keep in mind, a single number is still a very blunt tool. It’s context, not a verdict on whether a token is a gem or coal. Important: this gives no buy or sell signals. It doesn’t say a token is “good.” It estimates how likely the major supply is in weaker hands or bundles. A heavily weighted metric is median and average hold time across all tokens traded by each top wallet. Diamond hand wallets tend to lower the score; fresh trench coins with multi-wallets and bundles tend to score high. New tokens and sub 100k MC coins usually look very coal. Narratives and catalysts aren’t included, and a low score does not mean a coin can’t rug or go to zero. Please read through the FAQ section on the website for most of your questions or concerns, if it's not listed on there put it in the replies below and I'll try to answer. Claude code and Opus 4.5 are really fucking cool. I had basically zero prior coding knowledge before creating this and the entire site/code was all "written" in plain English from me, passed off to the AI. I plan to add some other features soon and keep the site running if the api costs don't get too expensive, so I will keep you all updated in this thread with any additional information or updates to the site. This is my first public vibecoded site, so bear with me. At the end of the day, I’m a trader. Not a webdev, coin dev, or deployer. I'm not launching a token personally, but I may support a token to cover api costs and keep the site running + add additional features.
