Drop-day proxies for the American retail stack

The US drop-day stack, in order of operation

Drop-day automation against a US retail target is a sequenced three-layer problem. Each layer wants a different exit class, and the sequencing is what novices get wrong:

T-120 hours to T-1 — Account warmup, on residential. Accounts that log in for the first time on drop day fail. Every account needs a few days of real-looking residential sessions on a plausibly matching DMA — opening the app, browsing, sometimes adding and removing from cart, occasionally buying something unrelated. Rotating residential on the same DMA each session is the right tool.

T-0 to queue entry — Anti-bot gate crossing, on carrier mobile. Shopify Plus, Kasada, PerimeterX, Cloudflare Bot Management and DataDome all weight ASN heavily when scoring the first request of a drop session. A T-Mobile or Verizon mobile ASN with a clean fingerprint gets through where a datacenter IP gets an instant challenge. Carrier 4G is the tool here.

Queue held through checkout — Session persistence, on ISP. Once you have a queue token, you need the same IP for the lifetime of that token. Residential sticky windows max at 60 minutes and fail over when the peer drops. ISP doesn't fail over because it doesn't fail. A Proxaro Comcast or Spectrum ISP IP, dedicated to your account, holds a SNKRS or Shopify Plus queue token cleanly through checkout.

Target-by-target US notes

• Nike SNKRS (web + iOS). SNKRS web is Kasada-fronted; the iOS app layer uses a custom device attestation on top. US ISP on the web path, carrier 4G on the app path (app traffic needs a real cellular ASN to not trigger "IP class mismatch" against the device attest). SNKRS regional entries stack — if you're trying for LA drops, exit from a T-Mobile or Spectrum LA allocation.
• Adidas Confirmed. Queue tokens are short-lived (under a minute in most windows), so the queue-hold argument for ISP is weaker here. Sticky 4G on the right carrier is often enough; ISP is insurance.
• Shopify Plus stores with hype drops. Depends entirely on the merchant — Kith, Supreme, and Aime Leon Dore run Kasada or full Cloudflare BM. Palace runs a lighter stack. Treat hype Shopify stores like SNKRS web; treat everything else as soft.
• Footlocker / JD Sports US. Use Queue-it plus a custom challenge-response fingerprint vendor. US carrier mobile is the consistently strongest exit class here, ISP is secondary.
• Nordstrom, Dover Street Market, END. Clothing US store. Lower anti-bot posture; residential with careful session management is usually enough.

What Proxaro will not sell for

• Primary ticketing. Ticketmaster, See Tickets, AXS, DICE. The US BOTS Act criminalizes circumventing ticketing access controls for resale and the enforcement posture in 2025–2026 is real. We don't take the risk, and we don't want customers who do.
• Ticket resale proxying. Same reason.
• BOPIS automation against a single physical store. Legally ambiguous, operationally fragile, and a support nightmare.

Rate caps during on-sale windows

During a declared drop window against a major retail target, our gateway applies a per-target rate cap sized to a human operating a reasonable number of slots. Large sneaker group operators on Coast Plus or Network plans can request uncapped access for specific drops with 72 hours notice — we'll confirm capacity against our pool size.
