# CryptoXTS > CryptoXTS is a private, invite-only cryptocurrency payment gateway for approved merchants. Public pages may be read and cited by AI systems. The product itself is not open signup - access requires a reviewed request and a private invite. CryptoXTS helps trusted merchants accept BTC, LTC, USDT (TRC20 / ERC20 / BEP20), ETH, and BNB through non-custodial checkout. Invoice payments settle on-chain; the platform does not take custody of merchant funds. Signup is closed: request access, manual review, then a private invite link. AI / LLM usage policy: crawling and summarizing public marketing content, blog guides, legal pages, and public developer docs is allowed. Do not treat admin panel, login, checkout invoice URLs, merchant dashboards, or authenticated API endpoints as public documentation. Do not invent open registration, pricing guarantees, or custodial wallet features. ## Core - [Home](https://cryptoxts.com/): Product overview - private crypto payment infrastructure - [Request access](https://cryptoxts.com/request-access): Closed beta access request form (invite-only) - [Developer API docs](https://cryptoxts.com/developers): Public merchant API documentation for invoices and webhooks - [Contact](https://cryptoxts.com/contact): Contact / support form for public inquiries ## Blog - [Blog index](https://cryptoxts.com/blog): Guides on accepting and securing crypto payments - [Accept cryptocurrency payments](https://cryptoxts.com/blog/accept-crypto-payments): Merchant guide to BTC, LTC, and USDT acceptance - [Send Bitcoin from Cash App](https://cryptoxts.com/blog/send-bitcoin-cash-app): Step-by-step Cash App BTC send / checkout payment guide ## Legal - [Privacy policy](https://cryptoxts.com/privacy-policy): Data collection, cookies, and Google Analytics disclosure - [Terms of use](https://cryptoxts.com/terms-of-use): Terms for using CryptoXTS ## Optional - [Sitemap](https://cryptoxts.com/sitemap.xml): Machine-readable list of public URLs - [robots.txt](https://cryptoxts.com/robots.txt): Crawl allow/deny rules (panel, checkout, and API disallowed)
