Why Your Custom Token Won’t Sell: Top Reasons & Fixes in 2026

According to CoinMarketCap, the total number of cryptocurrencies was 29.91 million in January 2026. This is an enormous number that allows crypto users to build a diversified portfolio. However, the main problem is that no single crypto platform, such as an exchange or a wallet, can support all crypto tokens worldwide.

In this case, you can manually add a custom token, but some users may encounter issues with selling and swapping. Let's break down how to solve this problem in Coin Wallet.

How to Add a Custom Token

For example, you want to use some new token, but it doesn't exist in the Coin Wallet portfolio by default. So you should manually add the desired token using the special function ‘Add custom token’. Learn more about how to do it correctly in our special guide.

When you add your token successfully, you may face some problems: the token may not be sold or bought. What should you do?

Common Reasons You Cannot Sell or Buy

Firstly, it's possible because the token could turn out to be a scam. In this case, we highly recommend not doing nothing. Many of these tokens (often called "dust") are designed to trigger a malicious script the moment you try to swap, sell, or even "approve" them.

Secondly, the token has not been added to a liquidity pool, or there are other technical problems that you cannot solve on your own because they are beyond your control. For example, the creator of this token froze it, prohibiting specific addresses from selling.​

Finally, the main reason is that your custom token isn't supported by Coin Wallet by default. It is generally concerned with little-known and scam tokens. It is thought that tokens like these cannot be bought through on-ramp services or swapped.​

💡 Kind reminder: the opportunity to add a token manually doesn't mean that this token is officially supported for selling, buying, and swapping.

How to Solve the Selling and Other Problems with a Custom Token

So you've already made sure your custom token isn't a scam and that there are no technical issues. This means that your token just isn't supported by Coin Wallet or other crypto platforms.

​However, the solution exists. But you can usually swap them on a platform like Uniswap, which Coin Wallet can connect to via WalletConnect.

Frequently Asked Questions

Why am I not able to sell my crypto?

Most of the time, it comes down to gas fees or slippage. You need to have enough of the network’s native coin (such as ETH or BNB) in your wallet to pay the transaction fee. If you have that covered, try increasing your slippage tolerance — if the price is moving too fast, the trade won’t go through unless you give it some wiggle room. However, there are other problems, such as not being supported by a crypto platform.

Why is my token not tradable?

This usually happens because there’s no liquidity. For a trade to happen, there has to be a “pool” of money for that specific token. If the developers haven’t added liquidity yet, or if they’ve pulled it out, you’re stuck holding it. It could also be that the token is still in a “vesting” or “locked” period, where you can see it in your wallet, but you aren’t allowed to move it yet.

Why cannot scam tokens be sold or swapped?

These are called “honeypots.” Scammers write a specific piece of code into the smart contract that allows people to buy the token but “turns off” the ability to sell it for everyone except the scammer’s own wallet. If you’ve got plenty of gas and you’ve cranked up the slippage, but the transaction still fails, the contract is likely hardcoded to trap your funds. There’s unfortunately no “fix” for this because the rules are baked into the token itself.
