Put your crypto service in front of buyers
pay-castle reaches people at a high-intent moment: they're actively converting dollars to crypto and taking self-custody. If you run a wallet, dApp, exchange, tax tool, or hardware product, that's your audience.
Homepage sponsor slot
A tasteful, clearly-labeled sponsor placement on the highest-traffic page, beside the buy panel.
Products feature card
A dedicated card on our Products page describing your tool, with a link out. Great for wallets and dApps.
Co-marketing & integrations
Bundle an embeddable buy widget with a placement, or co-author a self-custody guide. Let's design something that fits.
Our standards: we only run ads for legitimate, non-deceptive crypto services. No "guaranteed returns," no investment schemes, no impersonation. Every placement is labeled as advertising. We may decline anything that could mislead our users.
