Open placements sell at base price. Held placements can be taken over at:
max(base, 1.2 × price paid × 0.95^days held)
The premium decays 5% per day, so nobody can squat forever. Prices are computed server-side at quote time.
USDC or the native token on Base and Solana. Payment is verified on-chain before your placement goes live.
PNG / JPG / GIF / WebP up to 2 MB, or a text card. Standard placements render at 480×270; the center placement at 960×540. Purchases are final after confirmation— a takeover doesn't refund the previous holder; they had their air time. Scam, NSFW, or heinous content is removed without refund.
