If I will create a new wallet on my Trust wallet app,
then move my funds from my old wallet to the new wallet and accept the contract call on my old wallet, will the new wallet can be at risk somehow? or this smart contact script can only affect the wallet which got it?
If it might risk any wallet , I will install metamask and move my funds there
Question is how deep a smart contract call might go? wallet level/app level/my entire device level???
Creating a new wallet address in your trust wallet and using for the contract call, still have a chance of affecting your other wallet address and that's depending on the type of contract you are accepting and if the guy have a malicious intention then this might be bad and so it's better to avoid this whole process than taking the risk.
Moving your coin to metamask seems like a better plan but I hope you're not going to import the seed phrase from your trust wallet there with this your coins are saved if you the sender have malicious intent. But I would have advised you to sign the contract using the new wallet address you are going to have in your metamask than moving your coins there since it will save you transaction fees charges and also if received alot from your trust wallet then this would be better since some people might not be aware of this changes and transfer coins to you in that address.
After signing the contract, you can revoke it later:
