I think Trustwallet works closely with the contract security auditing companies AvengerDAO and Hashdit. You can find out the malicious level of the contract address you want to link to from the announcement history of these two companies.
The funny thing is I have used the platform before and things went smoothly, I never got this same warning at the time, I think it's just a month ago.
If you believe that these 2 audit firms are credible enough, then heed the warning. If you are more confident it will be fine as before, then go ahead. Just think if some things have changed since your usage last month and a vulnerability was detected minutes before this warning.
it really depends on the OP if he will still use the platform despite of the warning. the risk is on him so if in case something goes wrong once he uses it, then, that's on him. it is a warning, so it is up to you if you will be cautious or will just proceed at your own risk. for me, i better look for other DEX, which is more popular and solid.
The risk of decentralized wallet assets depends entirely on the individual themselves. Protecting the private key and mnemonic is the guarantee to avoid risks. The security of the blockchain is always a topic of greatest concern to each of us. When you interact with contracts, you need to pay more attention to whether you are using genuine software or applications. Many hackers will use this to steal users' wallet assets.
