What is a token? And what is the difference from a coin?

A crypto "coin" is deemed a financial asset with the unique function of making payments, wherein it is fungible, divisible, acceptable, of limited supply, uniform, portable and durable. Coins are
independent of other chains and can’t be used on other chains in their native form.

A crypto "token", by contrast, has extended functionality that goes beyond a form of monetary exchange. Tokens are issued through the operation of a smart contract and can enable cross-chain communication and compatibility. Unlike coins, tokens can be supported by different blockchains.
