A token is a digital asset issued on an existing blockchain, typically through a smart contract. Unlike native coins, which have their own blockchain (e.g., Bitcoin or Ethereum), tokens rely on a host network like Ethereum (ERC-20), Binance Smart Chain (BEP-20), or Solana. Tokens can serve various functions, including representing assets, granting access to a platform, facilitating transactions, or enabling governance within a decentralized network. They are widely used in applications such as decentralized finance (DeFi), gaming, and tokenized assets.
