If you haven’t heard, PancakeSwap is among the leaders in decentralized exchanges. Traders and investors use the platform to trade their favorite BEP-20 tokens. These are tokens that reside on the Binance Smart Chain (BSC). BSC charges its users less in trading fees and offers faster transactions than its Ethereum counterpart.

The thing to keep in mind with decentralized platforms is that they’re still in their infancy. As a result, it’s not uncommon for users to run into problems. These could be errors that occur while attempting to connect a crypto wallet or problems that users encounter while trying to swap tokens.

A very common error PancakeSwap users run into is the infamous Unsupported Chain ID. This problem occurs when the user is trying to add their crypto wallet to the PancakeSwap platform.

While running into errors can be a source of frustration, the good news is that this one isn’t too difficult to fix. Many PancakeSwap traders and investors have had trouble with this error, which means there’s a fix in place. Our how-to guide will tell you exactly what you need to do to fix the Unsupported Chain ID issue that occurs on PancakeSwap.

What is the Unsupported Chain ID error?

PancakeSwap users get the Unsupported Chain ID error when they’re attempting to connect their Trust Wallet to the PancakeSwap exchange. This happens because the wallet is already connected to another blockchain. 

The problem is that PancakeSwap operates on the Binance Smart Chain network. So if you try to connect to it while your wallet is still using a different blockchain, you get an error. The error occurs because PancakeSwap doesn’t play well with other networks.

Steps to Take to Fix PancakeSwap’s Unsupported Chain ID

We’ve already discussed why the Unsupported Chain ID error occurs, so let’s talk about how to correct it on PancakeSwap. The solution is simply switching the current blockchain your wallet is connected to over to the Binance network. Doesn’t sound too complicated, right? It’s not.

By default, Trust Wallet is connected to Ethereum. This guide will show you how to correct the error in the wallet so you can connect to PancakeSwap.

Step 1. Launch PancakeSwap exchange

Step 1

The first thing you need to do to correct the Unsupported Chain ID error if you’re using Trust Wallet is to launch the wallet itself, then go to the dApps browser. Once there, select PancakeSwap so the exchange launches.

Step 2. Select the Ethereum icon

Step 2

Now that you’re on the PancakeSwap exchange, look in the upper right corner of the screen. You should see an Ethereum icon to the right of the three dots. Click on it to change the blockchain you’re connected to.

Step 3. Switch blockchains

Step 3

Once you click on the Ethereum icon, you’ll get a list of blockchains from which you can choose. You don’t have to look too hard to find Binance Smart Chain. It’s near the top. Select it to ensure the appropriate blockchain is used when attempting to connect to PancakeSwap.

Step 4. Connect to the PancakeSwap exchange

Step 4

With the correct blockchain selected, you can go back and try to connect to PancakeSwap again. When prompted, choose Trust Wallet. This will connect the exchange with your Trust Wallet.

Step 5. Confirm the connection

Step 5

The last thing you need to do is hit the Connect icon. This authorized the connection and establishes communication between your Trust Wallet and the PancakeSwap exchange. 

That’s all there is to it! You have now fixed the Unsupported Chain ID error that pops up when attempting to connect your Trust Wallet to PancakeSwap.

Here are a few commonly asked questions about fixing the Unsupported Chain ID error on PancakeSwap:

What does Chain ID mean?

Chain ID stands for chain identifier. This is a unique value assigned to each blockchain that confirms transactions through signatures on each wallet. Every blockchain is given a unique chain ID, which means there are no duplicates. The most common chain ID is Ethereum, which has a value of 1. By comparison, Binance Smart Chain’s chain ID is 56.

What is the Unsupported Chain ID error?

The Unsupported Chain ID error occurs when the wrong chain is selected. So if you’re attempting to connect to PancakeSwap, a Binance Smart Chain platform, using Ethereum’s blockchain, it’s not going to work. As a result, you get the Unsupported Chain ID message.

What is the correct Chain ID for Pancakeswap?

Since PancakeSwap supports the Binance Smart Chain mainnet, it uses the same Chain ID. That means to connect to PancakeSwap you need the Chain ID to be 56. 

Getting Connected

If you get the dreaded Unsupported Chain ID error when trying to connect your Trust wallet to PancakeSwap, there’s no need to panic. Just follow the steps outlined above and you’ll be ready to use PancakeSwap before you know it.
