Cryptoassets are covered in full in the entry Crypto Asset, which explains the main types, how they are classified and how they are regulated. This page gives a short definition and explains the spelling.
A cryptoasset is a digital representation of value or rights that is recorded on a blockchain or similar distributed ledger and secured by cryptography. The category is broader than cryptocurrency: it includes coins such as bitcoin, utility and governance tokens, stablecoins, non-fungible tokens and tokenized securities. Regulators often prefer the term because it does not imply that the asset functions as money. The European Union's MiCA regulation, for example, defines "crypto-assets" and splits them into e-money tokens, asset-referenced tokens and other crypto-assets, while excluding those that qualify as financial instruments under existing law.
"Cryptoasset", "crypto-asset" and "crypto asset" are different spellings of the same term; British regulators such as the Financial Conduct Authority have tended to write it as one word. A broader category is described under digital assets.
