Then 3 days on POPCAT mainnet, every alert checked against Solscan. 3 more bugs, incl. a wallet holding dust that showed "Position +594,210%". Now: "New holder!" Real traffic finds what tests don't. Full write-up + the parsing code below 👇

Bug 2: worked on Windows, silent on Linux. Env var names are case-insensitive on Windows, not on Linux. Bug 3: .gitignore shipped as "gitignore". Without the dot it does nothing. Users could have pushed their bot token to GitHub. Test on the OS your users run.

Bug 1: doubled amounts. I summed token transfers. A swap moves tokens out of the pool AND into the buyer, so both got counted. Fix: ignore transfers. Read preTokenBalances / postTokenBalances and compute the net change per wallet. Pools are never buyers.

I audited the Solana buy bot I was selling. Found 5 bugs. One doubled every buy amount. Another posted zero alerts on every Linux VPS. I stopped selling it and rewrote it. Here's the post-mortem 🧵
