Start with the workflow, not a profit claim
A credible automation product states what data it observes, what decision rules it applies, where execution happens and which safeguards stop an action. Treat guaranteed-return language as a risk signal.
Map the complete operating cost
The license price is only one component. Include VPS hosting, RPC access, exchange fees, gas, market data and engineering support. Model costs against realistic volume rather than best-case screenshots.
How to evaluate a Polymarket bot
Queries such as “how to build a trading bot for Polymarket” and “polymarket bot github” usually want the same stack: CLOB market discovery, YES/NO arithmetic after fees, a host you control and a kill switch. A commercial Polymarket trading bot is that stack already wired. A public repo is usually one strategy and no production loop. If the job is copy-trade, you still size fills locally. If the job is Polymarket versus Kalshi, you need a second venue adapter — that is a separate SKU, not a checkbox on the Polymarket-only bot.
Require a defensible security boundary
Private keys should never enter the storefront. Exchange API keys should be withdrawal-disabled where possible. Secrets belong in the deployment environment, not source control or browser JavaScript.
Demand observable execution
A system should record the market state, route estimate, configured limits, submitted transaction and final status. This makes failures diagnosable and prevents the dashboard from becoming a marketing-only surface.
Use a controlled checkout
This storefront sends only the server-side product price, currency, order ID and redirect URLs to NOWPayments. The API key remains server-side. Signed IPN callbacks update the local order record.
