🧠 New Update – Advanced Simulation 🧠

Troubleshooting failed simulations just got a whole lot easier.

We’ve just upgraded our simulation system to give you clearer, more actionable error messages when something goes wrong. Instead of a generic error message, you’ll now see detailed explanations on why a simulation failed and suggestions for how to fix the issue.

This is all powered by our custom-built simulation engine, developed to give us full control, deeper insights, and far more accurate results than any third party or off-the-shelf tool.

🔴 Red = the raw error from your contract or Uniswap
🟡 Yellow = our suggestion to help you fix it
📘 You can find a full list of known errors and solutions in our docs below.

🔵🔜 What’s next?
This was the final piece we needed before launching full support for Base Chain — and we’re happy to announce that it's coming next week! It’ll be free for all users in the first few days, so keep an eye out.
