It's a great question!

When choosing a decentralized exchange script, it's important to focus on a secure framework. Honestly, having a strong, reliable foundation is key to building something that will last.

When thinking about what makes a decentralized exchange script safe and reliable, here are a few gentle suggestions:

• Look for an audited smart contract - The self-executing codes need to be carefully checked, and perhaps check again after updates.

• Protected Trade Logic - With this, trades will be processed more protected while keeping prices fair and stable.

• Secure Wallet Connection - The protocol needs to connect with various crypto wallets like WalletConnect or Metamask with extra care.

• Modular Framework - A code that keeps different components (trading, liquidity, governance) in separate spaces, so each part can be updated smoothly.

And something that’s often ignored—role-based admin control, so backend access doesn’t become a liability.

From what I’ve seen recently, some of the better scripts are now including anti-sandwich attack protection, dynamic slippage settings, and improved token verification layers. Those are things you definitely want baked into the base code, not added later as a patch.

Also, try to get a script that’s not just a fork of a fork. Some clones out there look fine on the surface but break down fast under real usage. If you're going long-term with this, clean architecture and a transparent roadmap are a must.

If you are looking for a reliable decentralized exchange script, then you need to obtain the script from a good firm.

My personal recommendation is Trioangle, they are one of the good DEX development companies that exist in today’s era.
