Cryptographic tokens are digital assets that use cryptography for security and are often built on blockchain technology. They can represent various forms of value, such as currency, assets, or access rights, and are typically used in decentralized applications and platforms. These tokens can be classified into two main types: fungible tokens, which are interchangeable and have a uniform value, like Bitcoin or Ethereum, and non-fungible tokens (NFTs), which are unique and represent ownership of specific items, such as digital art or collectibles.
