I Found a Useful Testnet DEX Frontend for TRON Nile and BSC Testnet

I recently came across an open-source project from PandaTool called OpenTools.

GitHub: https://github.com/pandatoolcode/OpenTools

It is not a complicated framework, and it is not trying to be an all-in-one developer suite. But for Web3 developers, especially those who often test token swaps, liquidity pools, approvals, and DEX flows on testnets, I think it is a pretty useful tool to keep around.

Many developers have probably run into the same situation before.

You deploy a test token.You want to test whether it can be traded.

You want to add liquidity, remove liquidity, check the swap path, test approvals, verify price quotes, and see whether the LP tokens work properly.

In theory, all of this can be done by calling contracts directly. But in practice, it is not always convenient. You need to check the router address, factory address, pair address, token decimals, approval status, slippage settings, and sometimes even different swap methods. If you are working across multiple chains, this becomes even more annoying.

This is where a ready-to-use testnet DEX frontend becomes useful.

PandaTool OpenTools currently includes two main tools.

The first one is TRON Nile DEX Tool, built for the TRON Nile testnet.

It supports TronLink wallet connection and allows developers to test TRX-to-TRC20 swaps, TRC20-to-TRC20 swaps, liquidity addition, liquidity removal, and LP token information queries.

The second one is BSC Testnet DEX Tool, built for the BSC testnet.

It follows PancakeSwap V2-style interaction logic and supports MetaMask. Developers can use it to test BNB-to-BEP20 swaps, BEP20-to-BEP20 swaps, liquidity addition, liquidity removal, pool information queries, and related DEX operations.

What I like about this project is that it solves a very specific problem:

Testnets have chains and contracts, but they often lack a convenient frontend for interaction.

This is especially true when working on token contracts.

After deploying a token, you usually need to test whether it can be swapped. After creating a trading pair, you need to test whether liquidity can be added. After adding liquidity, you need to test whether swaps work correctly. If the token has transfer tax, dividend logic, buyback logic, or other custom mechanisms, you may also need to test whether the swap method supports fee-on-transfer tokens. Once LP tokens are generated, you may also need to test LP balance queries, approvals, and liquidity removal.

None of these tasks are extremely difficult, but they are repetitive. If you write a temporary frontend every time, it wastes time. If you rely only on scripts or block explorers, the workflow is not very smooth either.

That is why a lightweight frontend like OpenTools is valuable. It may not replace a production-grade application, but it is very suitable for debugging, demos, and quick testnet verification.

Another good thing is that the project is built as a static frontend. It does not require a complex backend, database, or server-side infrastructure.

Developers can use the online version directly, or they can fork the repository and customize the router address, factory address, token list, contract addresses, and network settings. It can also be used as a simple template for building internal test tools or testnet interaction pages.

For solo developers and small Web3 teams, this kind of tool is often more useful than a heavy framework. In day-to-day development, the problem is not always a lack of technical knowledge. Sometimes, what you really need is just a page that lets you test things quickly.

Of course, OpenTools is still an early and practical tool collection. The interface and features are more utility-focused than polished commercial-product style. But as an open-source project, I think the direction makes sense.

There is a lot of repeated work in Web3 development, especially around testnet tools, frontend interactions, and demo pages. If more of these small but useful tools can be open-sourced, developers can save time and focus more on the actual product logic.

It is also worth paying attention to PandaTool itself.

Many people may know PandaTool because of its one-click token creation tool, which allows users to create tokens on multiple blockchains without writing code. Besides that, PandaTool also provides tools for batch transfers, liquidity management, token utilities, testnet tools, and other on-chain operations.

From the OpenTools repository, it is clear that PandaTool is not only building no-code tools for non-technical users. It is also starting to open-source tools that developers can use for testing, demos, and secondary development.

Personally, I think this is a healthy direction. If a Web3 tooling platform only serves beginners, its value is somewhat limited. But if it can also serve developers and provide tools that can be modified, reused, and extended, the ecosystem becomes much more interesting.

If you are currently working with TRON Nile, BSC Testnet, test tokens, DEX interactions, liquidity pools, or tax-token testing, I would recommend bookmarking this repository.

It is not a heavy project, but it can save time.

And in development, tools that save time are usually worth recommending.
