Sellix
London, United Kingdom
What it is
Sellix is a commerce platform for merchants selling digital and physical goods through public shops, hosted checkout, and a management dashboard. Its checkout is crypto-only: buyers select supported crypto assets, and displayed fiat prices are converted during checkout. Card payments are unavailable. The catalog covers license keys, downloads, accounts, Discord roles and invites, physical goods, subscriptions, and custom dynamic payloads. After payment confirmation, delivery can issue keys or signed download links, send webhook payloads, or show physical-order fulfilment status. Merchants can use the REST API and webhooks for custom integrations; documented options include BlockPN settlement and Discord role or invite delivery. API keys have granular permissions, expire within at most 90 days, and can be revoked. Webhooks use HMAC-SHA256 signatures and may be retried up to six times. Sellix says BlockPN settles payments to the merchant's wallet and that Sellix does not hold or control funds. The plan costs nothing, with no subscription, take-rate, or expiry, and includes unlimited shops, products, orders, and customers. Sellix is available on the web and through an API.
