We have spent several hours of research on this project to be able to give a clear verdict on our findings, however we have concluded to leave LinkSync in ⚠️Partial Check (DYOR) category.

✔️71 points. All main functions have been implemented and the contract looks good. DYOR before investing. Reference
On the other side we had some different discoveries on Moonarch.app, apparently the contract has some functions that can be risky for investors. Reference

And also on the holders section, besides the Burn Wallet there are 2 other ranks bigger than LP.

The second wallet is a Contract, but we couldn't find any information regarding this contract on the Whitepaper. Usually most teams add as much information as they can to be transparent with their members about everything revolving around their contract.
Besides that contract, there is also another wallet holding 1.5x+ times more than LP, which is also a risk if that wallet is managed by the team and is not locked.
LaserEyesScan had a good score on this project except some information that we think should be know by any investor looking to invest in this project:

We tracked the Dev wallets before and after transferring ownership, and there are a lot of unexplained transfers that are made before and after the token has launched. Reference

In a conversation with Nick, one of the project devs, it was made known to us that they had a private sale before the launch for more stability on projects LP, and after that lately some of the investors parted ways and dumped.
But this doesn't explain the transfers made on 27.10 from the deployer wallet to several brand new wallets. Linksync team can comment on this post below for more information regarding this.
⚠️ Contracto Verdict: Partial Check, there may be risks involved.
