I dont really know, but many new projects claim that they are safe because already lock liquidity and doxxed by any trusted third party.
Its a good thing maybe, but for indicator i usually see how professional the team took care of its community and follow the roadmap.
third party audited could be the indicator for checking new projects but liquidity lock could withdraw anytime they want. there is no guarantee project that lock liquidity will be safe place to invest. i see many time dev team withdraw the liquidity till finally holder could not sell the token. The lastest case was VOLTNFT project, reasoning migrate to bsc platform they will unlock liquidity in uniswap and till now on they are come back. this is be new methode to scamm us.
