Disclaimer

Trust Wallet team allows anyone to submit new assets to this repository. However, this does not mean that we are in direct partnership with all of the projects.

Trust Wallet team will reject projects that are deemed as scam or fraudulent after careful review. Trust Wallet team reserves the right to change the terms of asset submissions at any time due to changing market conditions, risk of fraud, or any other factors we deem relevant.

Spam-like behavior, including but not limited to mass distribution of tokens to random addresses will result in the asset being flagged as spam and possible removal from the repository.

Additionally, it has come to our attention that some projects are trying to get their tokens added to the Asset database by airdropping tokens to several addresses in order to meet token holder count as well as the transaction requirements. Random airdrops to unsuspecting users is not allowed. We want our users to get tokens that they are expecting to receive and not those tokens that they didn’t signed up for.

We will implement stringent screening of submissions and also disable such tokens from showing on the app.
