Blockchains are not interchangeable payment rails. Every network makes different trade-offs around confirmation speed, wallet compatibility, transaction cost, token standards, and how much logic can be enforced directly onchain.
For CryptMeUp, that matters because checkout behavior is shaped by the chain underneath it. Some chains are natural fits for smart-contract-based payment execution and onchain fee splitting, while others are better approached through direct wallet settlement and prepaid platform capacity.
This section exists to explain those differences in practical terms. Use the chain pages to understand why certain networks are active today, which assets are typically relevant for checkout, and what merchants or developers should expect when using that chain for crypto payments.
