Fantom is another EVM-style chain that has historically been attractive in crypto because it emphasizes quick confirmation and lower-friction transactions. Those are naturally relevant traits for payments, where user patience and transaction overhead both affect checkout quality.
From a CryptMeUp perspective, Fantom fits conceptually into the same family of contract-capable networks that can support direct wallet checkout and token-based payment logic. Whether a chain is active in live checkout is a separate question, but the documentation layer still benefits from explaining how that chain sits inside the broader payment landscape.
