 - Free to join with email only (6-digit code sign-in, no passwords). Wallet appears only at purchase or payout activation. Every new member gets a small welcome batch of ad credits — unlocked by the WELCOME TOUR on first sign-in: they visit their upline's line-banner sites (up to 3, 10 seconds each — the same 3 levels the contract pays), then claim the credits. Members with no upline banners get the credits instantly.
 - LINE BANNER (free, set in Profile): every member can set a destination URL (must allow framing) plus an optional banner image. It is shown to their next THREE levels of new members during welcome tours (position 1 for directs, 2, 3 below), and on their public BANNER WALL at /wall/<username> — a shareable page showing their line ladder with their join link. Free viral traffic that compounds as the team grows; no credits spent.
 - Ad packages: Micro $5/500 credits, Activation $20/2,000, Builder $50/5,500, Growth $100/12,000, Leader $250/32,500. Dollar-priced, settled in POL (Polygon) at the live Chainlink rate. 1 credit = 1 cent of ad delivery.
-- Live formats: display banners (per impression), text ads (per impression), full-screen LOGIN ADS (per day: right after a member signs in they land on a sponsor interstitial — they click "Open Ad", the advertiser's page opens in a NEW tab, a countdown runs on the interstitial, and at zero a "Go to dashboard" button appears. Just a CTA link is enough; an optional banner image can be the clickable creative. No framing requirement since it opens in its own tab), and solo ads. Coming: featured rotation with disclosed rotation size, verified-visit packs.

Just a CTA link is enough; an optional banner image can be the clickable creative. No framing requirement since it opens in its own tab), WATCH-TO-EARN VIDEO ADS (advertiser uploads an MP4/WebM or gives a direct https .mp4/.webm link and picks a required watch length — 10s/30s/60s — which sets the per-view price; viewers watch in an escape-proof player under Earn credits > Watch videos, the watch time is enforced on the server clock, and they earn credits per completed watch; you never see your own videos), and solo ads. Banner ads also require a size (standard IAB sizes like 728x90, 300x250). Coming: featured rotation with disclosed rotation size, verified-visit packs.
 - Members EARN credits by attention: in the Earn credits section of Members, each ad in the daily set opens FULL SCREEN in its own tab, showing the advertiser's real website. A countdown runs while you watch (it pauses if you leave the tab), then a quick human check (click the named icon) must be passed before the view counts. Finish the daily set, claim a small daily credit batch. Earned credits spend on banner and text campaigns; attention earns advertising, referrals earn money, and viewer rewards are never cash. Advertisers get real, verified visits to their site.
 - Onsite SOLO ADS are live: a solo ad is a full message (subject + up to 2000 characters of formatted text + your link) delivered into members' on-site Inbox (Members > Inbox). The composer in Campaigns > Solo ad has a rich-text editor (bold, headings, lists, links), lets you ATTACH one image (PNG/JPG/WebP/GIF, up to 3MB) or one video (MP4/WebM, up to 25MB), and adds a call-to-action button with a custom label that opens the target URL. Cost 5 credits per guaranteed delivery, minimum 10 deliveries (50 credits). Each member receives a given solo at most once, and never the sender's own. Readers earn 2 credits per real read (10-second dwell on the open message, up to 5 rewarded reads/day) — claimed right from the message. Compose one in Campaigns > Solo ad.
 - Campaign target URLs are checked the moment they are submitted: the page must be reachable and must ALLOW framing (no X-Frame-Options deny/sameorigin, no blocking CSP frame-ancestors), because surf views show the real site full screen. Frame-blocking or dead URLs are rejected with the exact reason; the fix is a landing page that allows framing. Login-ad targets skip the frame check (they are click-through only).
