CartGate: Pre‑Checkout Bot Challenge
The Opportunity
Stop automated checkouts by forcing a human verification challenge at the cart and checkout initiation steps. Uses Turnstile/hCaptcha plus behavioral checks to ensure only verified sessions can proceed to checkout.
"Merchants cannot add reCAPTCHA directly to Shopify checkout on most plans, leaving bots free to initiate orders, especially harmful for COD where payment isn’t captured upfront."
Market Validation
Detailed Analysis
Proposed Solution
Insert a human verification gate on cart pages/drawers and on the ‘Checkout’ button; mint a signed token on successful challenge and enforce its presence via cart attributes and checkout validation so unverified sessions cannot place orders.
Target Audience
Shopify merchants (non-Plus and Plus) experiencing bot orders, flash bot traffic, or form spam, especially those using COD.
Competitive Landscape
Shop Protector by Human Presence, Fraud Filter by Shopify, General CAPTCHA/security apps
Implementation Notes
Provide theme app blocks for cart page/drawer and an app embed to intercept ‘Checkout’ clicks; render Turnstile/hCaptcha (with fallback honeypot/time-trap) and issue a short-lived signed token (JWT) stored in a cookie and cart attribute; add a Checkout Validation Function to block submission if the token/cart attribute is missing or expired (no network calls needed); add heuristics (mouse movement, typing cadence), IP/device fingerprinting, and rate limiting; for Plus, optionally render a lightweight verification notice in Checkout UI extensions; respect Shopify’s restriction on third‑party scripts in checkout by gating pre-checkout and validating via Functions.

"I hope someone can help me with this one, and that would be greatly appreciated."
