Supported Tokens

This chapter discusses the standard representation of tokens that have been moved from one blockchain to another.

Tokens that have been moved from a guest blockchain to a host blockchain must be represented using a standard token implementation that is common on the host blockchain. When introducing support for tokens, a standard token implementation must be chosen for every host blockchain.
