# Token warnings

**We at WAGMI want to help you safely browse and discover tokens and make informed decisions about them.**

 That’s why we introduced Token Warnings.\
\
You may see either red and yellow Token Warnings while swapping and navigating throughout the site. These warnings are to alert you to the potentially heightened risk in trading these tokens.\
\
Token Warnings are available for Ethereum (ERC-20) tokens and supported Layer 2 tokens.

### HOW TO ADD YOUR TOKEN TO TOKENLIST

Please read guidelines for submitting community PR for adding tokens to tokenlist.

**Criteria**

The Wagmi team will continue to maintain the list for quality control. Some rough guidelines:

* Contract should be verified on block explorers e.g. `explorer.zksync.io`
* Token should have established liquidity, a good number of liquidity providers, and 15 day volume.
