# Basics

## What are pegged value crypto assets?

Pegged value crypto assets are tokens that have their value pegged to an underlying asset by some means. The most common type of pegged value crypto asset is stable coin, of which the value is supposed to be $1.

Different pegged value crypto assets fix this value using different mechanisms. Some maintain their peg synthetically, like sUSD, other by being backed by the the actual underlying asset, like USDT.

These different approaches and the associated risks are why the prices of pegged value crypto assets of the same type can vary slightly.

## What is tokenized bitcoin?

Tokenized bitcoin is another frequently used pegged value crypto assets. The underlying assets, BTC, is kept in some ways and then a certain party will mint or issue a token on other blockchains that has the same value as regular BTC but can be used to the full capability of a token. Some examples of tokenized bitcoin include WBTC, HBTC, tBTC, renBTC, sBTC and so forth.
