Payments you can check on-chain
Every payment can be checked on the network, your keys stay yours and no other site can frame the payment pages.
Built to be checked, not just trusted.
Verified on-chain
A payment counts only once the network confirms it, and every paid checkout links the transaction in a public explorer.
Your keys stay yours
We never ask for a secret key. Payers sign in their own wallet, and you receive at an address you control.
Pages that can’t be framed
Checkout pages refuse to load inside other sites, so nobody can dress them up as something else.
Keys per environment
Test and live API keys are separate and scoped to one organization, with roles and permissions for your team.
Signed webhooks
Every event sent to your server is signed with HMAC-SHA256 and your endpoint’s secret, so your server can refuse one that did not come from Cosmos Pay.
Links that expire
A link can carry a deadline: the checkout counts down and stops asking for the payment once it passes.
Open documentation
The API reference, the SDK and the guides are public, with an OpenAPI spec you can check the API against.
