Big Brother

Trade smarter. Become a Big Brother. Big Brother Extension — Avg Buy / Avg Sell MC lines on the terminals you already use 📈 CHART LINES Avg Buy MC and Avg Sell MC for a rank range you choose (1–100). Holders and traders use different colors so the two books stay readable. Lines update with the token page. Toggle each line on or off. 👥 HOLDERS Weighted average by tokens held right now. Default: only wallets where GMGN already computed avg cost / avg sold. Optional phishing-wallet path uses transfer in/out from the same payload. Burn, LP, and your local blacklist are always excluded. The % on the label is supply covered by wallets that actually entered the average. 📊 TRADERS Top traders by profit. Equal-weight average (inventory is treated as zero). If GMGN is missing avg cost or avg sold, both sides are rebuilt from buy + tx in / sell + tx out. Trader lines can draw as soon as that set is in. 👁️ THE EYE A floating control on the chart: toggles, GMGN API Key, Test key, refresh. Gear → Docs (formula + optional Ed25519 public PEM for GMGN). Gear → Blacklist (local wallet list, used in the average). Gear → Account (pay, redeem, Recovery). 🔑 HOW TO USE 1. Open a token page. The Eye appears on the chart. 2. Paste a GMGN API Key from gmgn.ai/ai into the Eye or the popup and press Test key. The key stays on your device. 3. Gear → Account to pay or redeem a code. Save Recovery before you uninstall a paid install. 🔒 WHAT IT DOES NOT DO • It does not follow wallets, place trades, or give financial advice. • It does not generate a GMGN API Key. Docs can generate a public PEM that GMGN asks for; the API Key still comes from gmgn.ai. • It does not read your seed phrase or clipboard. Uninstall deletes the account secret on that device. • Chrome Web Store and unpacked installs have different IDs and do not share the same account.
