What does “Chain ID Not Supported” mean on PancakeSwap?
Unsupported chain ID means that the chain (Ethereum) does not support the token you are trying to trade.
For example, if you are looking to get SAFEBTC, you can only trade it on Binance Smart Chain (BSC) and not on Ethereum (ETH).
By default, the chain on PancakeSwap is Ethereum.
In the top right or left corner on PancakeSwap, you should be able to see the Ethereum icon.
This means that you are currently in the Ethereum chain.
However, you can only trade a token as SAFEBTC on Binance Smart Chain.
If you are looking to get a token like SAFEBTC, you need to check its contract first.
First, go to CoinMarketCap.com and search for “SAFEBTC”.
Under “Contracts” you will be able to see the address of the token.
You will also be able to see the type of token.
The token type for SAFEBTC is “BEP-20”, which is a token standard on Binance Smart Chain.
That said, you can only trade BNB with SAFEBTC.
How to Fix ‘Chain ID Not Supported’ on PancakeSwap
To fix ‘Chain ID Not Supported’ on PancakeSwap, you need to switch the chain to Binance Smart Chain (BSC).
After changing your chain to Binance Smart Chain, you will be able to successfully trade your tokens.
Having Binance and Trust Wallet are prerequisites for this guide.
If you don’t own any BNB, you need to buy it from Binance and transfer it to Trust Wallet.
This is because you won’t be able to use Ethereum to trade the token you want to get.
In addition, you install the Trust Wallet mobile app and enable the DApp browser.
Do not use PancakeSwap on your browser (e.g. Safari, Chrome) as you may experience problems later.
Here’s how to fix “Chain ID Not Supported” error on PancakeSwap:
1. Buy BNB from Binance
Skip this step if you already have Binance Coin (BNB) on your Binance Smart Chain (BSC) wallet on Trust Wallet.
The first step is to buy a minimum of 0.1 BNB.
If you already have BNB on Trust Wallet, you need to exchange it for Binance Smart Chain.
You can do this by tapping “DEX”, selecting “BNB” on “You Pay” and selecting “Binance Smart Chain” on “You Get”.
Then, enter the amount of BNB you want to trade with Binance Smart Chain and tap “Swap” to exchange it.
If you don’t have BNB, you can buy it on Binance or Trust Wallet.
However, it is highly recommended to buy BNB on Binance.
This is because the fees for buying BNB on Trust Wallet are extremely high (up to 5%).
On the other hand, Binance only has a 0.1% commission.
If you don’t have a Binance account yet, you can use the link or code above to sign up for an account.
After purchasing BNB from Binance, you need to transfer it to your Binance Smart Chain wallet on Trust Wallet.
2. Tap the chain icon
Once you have Binance Smart Chain on Trust Wallet, you will be able to exchange it for another token.
First, tap on “Browser” in the bottom navigation bar on Trust Wallet.
Then, scroll down and tap on “PancakeSwap” under the “Popular” heading.
Once you are on PancakeSwap, you will see the Ethereum icon at the top right or top left of the screen.
By default, PancakeSwap will be on the Ethereum chain.
However, Ethereum does not support the token you are trying to trade, so you will have to change it to Binance Smart Chain.
Tap the ethereum icon at the top right or top left of PancakeSwap.
3. Tap “Smart Chain”
After tapping on the Ethereum icon, a navigation menu will open.
In the navigation menu, you will see multiple chains like “Ethereum”, “Smart Chain”, “POA Network”, “GoChain” and more.
You need to select the chain that supports the token you are trying to trade.
To verify this, look for the token on CoinMarketCap.com.
Then, navigate to the token contract under the “Contracts” heading.
If the contract has a Binance Smart Chain icon, it means that you need to select “Smart Chain”.
However, if the contract has an Ethereum icon, you need to select “Ethereum” instead.
In most cases, the chain you need to select is “Smart Chain”.
Tap “Smart Chain” to change the chain on PancakeSwap to Binance Smart Chain.
After selecting “Smart Chain”, you will be able to exchange BNB for the token!
Conclusion
If you are looking to trade cryptocurrencies on PancakeSwap, make sure that the chain you have selected supports the token.
For example, tokens such as Safemoon and Kishu Inu can only be exchanged for Ethereum.
On the other hand, tokens such as Spore Finance and Bonfire can only be exchanged for BNB.
To change the chain, simply tap the chain icon at the top right or top left of PancakeSwap.
