What are token warnings?

Token warnings help users make informed decisions about tokens.

 

You may see info labels or token warnings while swapping and navigating tokens throughout our interface. These warnings are intended to provide you with extra information about a token. Token warnings are not investment advice or recommendations on a particular token.

Token warnings are available for Ethereum (ERC-20) tokens and supported Layer 2 tokens.

How are token warnings created?

Token warnings are created using information from Blockaid. Blockaid employs a combination of dynamic and static heuristics, AI, and machine learning models to scrutinize each new token created onchain. Uniswap Labs does not guarantee their accuracy and makes no representations or warranties about their relevance or currentness. Data may not be available for selected tokens, particularly newer or less popular tokens, and no tokens are reviewed for their quality, merits, or soundness as investments.

Blockaid is not an affiliate of Uniswap Labs, and Uniswap Labs does not independently verify information provided by Blockaid. If you have any questions or concerns about warnings on specific tokens, please reach out to the Blockaid support center here.

 

Additional Disclosure

Token warnings are not investment advice and should not be construed as such. They do not purport to be exhaustive as to all potential risks; always conduct your own research about tokens before buying or selling them. All information is provided for informational purposes only and is not a recommendation of any investment strategy, nor is it a solicitation to buy or sell any investment. You are responsible for making decisions about whether any purchase or sale is appropriate based on your own objectives and risk tolerance.
