# Cronos chain tokens

To operate on the CRONOS chain you will need two types of tokens:

# Native CRO tokens

  • These tokens will serve to pay transaction fees (GAS) on PlaySwap and all other Cronos apps.

# CRC20 tokens

  • CRC20 is a token protocol closely resembling Ethereum's ERC-20 for interoperability
  • Except for native CRO, all other tokens are CRC20 tokens
  • Tokens native to other blockchains (BTC, USDC, ETH) are wrapped into CRC20 tokens.
