Manuals and blockchain references

CryptMeUp is built around direct crypto payments: merchants configure payment flows, payers complete checkout, and funds move to merchant-controlled wallets instead of into a custodial platform balance. The goal is to make crypto payments operationally simple without hiding how the payment actually works.

On supported onchain-fee networks, the payment itself and the platform fee are handled transparently as part of the same onchain execution path. The fiat amount shown in checkout is always the fiat conversion for the payment itself; network gas or chain transaction costs remain separate and are never silently baked into that payment amount.

On networks where the fee cannot be split onchain, CryptMeUp uses prepaid payment capacity instead of hiding the platform fee inside an opaque conversion spread. That keeps fee logic understandable per chain model while still allowing merchants to receive funds in their own wallet context.

The pages in this section are meant to answer practical questions: when to use Basic Payment versus Permanent QR, how Commerce Checkout is meant to be integrated, what merchant checks are required, and why some chains behave differently from others in checkout. If a merchant, developer, or reviewer needs context, the Knowledge Bank should be the place where that context is clear and auditable.

Use the Manual when you need operational guidance, open Blockchain when you need chain-level context, and open Other when you need explanations about fee logic, wallet-to-wallet transparency, or payment validity windows.
