What are token warnings?#
Last modified: August 10, 2026
Token warnings help users notice possible token risks while swapping and browsing in the CenturionDEX interface. They provide extra context about a token, but they are informational only. They are not investment advice, a recommendation, or a guarantee that a token is safe or unsafe.
Token warnings are available for CRC-20 tokens on Centurion. Token and pool creation is permissionless, so a token appearing in CenturionDEX or in a Centurion pool is not an endorsement by Centurion Labs.
What the different warnings mean#
| Label | Meaning |
|---|---|
| Malicious – General | Flagged as potentially malicious. The token may be related to harmful activity, phishing, a drainer, or malicious contract behavior. See Malicious token contract scams. |
| 100% Sell Fee Detected | Selling sends all of the token's value away from you, so you receive nothing. See High-fee token scams. |
| Impersonator | Flagged for imitating a different token. Use the contract address to confirm you have the token you intend to swap. See Impersonator token scams. |
| Honeypot | Flagged as a potential honeypot: a token that may allow buying but block or severely penalize selling. |
| Spam | Flagged as potential spam based on the token's on-chain airdrop history or distribution pattern. See Spam token scams. |
| High Buy or Sell Fee | Charges a high fee when bought or sold. Swapping may result in receiving much less than expected. See High-fee token scams. |
| Warning | Limited trusted market information is available, such as not being traded on a leading centralized exchange used by the screening provider. This is not a safety approval or rejection. |
| Not Available | Not supported in the CenturionDEX interface. See the Unsupported Token List. |
What it looks like#
You search for a token and see an Impersonator warning. The token name and logo match what you expected, but the contract address is different from the real project's published address. The warning is telling you to stop and verify the contract before swapping. It is not telling you whether the real token is a good investment.
Where warnings come from#
Warnings are generated using a third-party token-screening provider, combined with on-chain heuristics. These systems can consider contract behavior, reported abuse, token distribution, swap results, airdrop patterns, and other risk signals.
Centurion Labs does not guarantee warning accuracy or completeness. Data may be unavailable for newer or less popular tokens, and automated scanners can miss owner-controlled changes, proxy upgrades, address-specific restrictions, or novel scam designs. A token with no warning, a green score, or ordinary-looking activity is not guaranteed to be safe.
How to use a warning#
- Read the exact label, not only the color or icon.
- Verify the token contract address from independent sources.
- Review fees, transfer restrictions, liquidity, and recent swaps where possible.
- Cancel if the wallet request does not match the action you started.
- Do not treat the warning as investment advice or a Centurion Labs endorsement.
If you believe a token is on the Unsupported Token List in error, you can file an appeal.
