The “Insufficient Liquidity For This Trade” issue is a relatively common occurrence on Decentralized Exchange, such as Uniswap, Pancakeswap or Sushiswap.

When you encounter this error, it’s likely due to the pool’s limited capacity to facilitate your trade, due to, well, as the name says, not enough liquidity. You’ll need to take a closer look at your trade size and consider a few different ways of solving this issue. We’ll go into this in more detail in this article.

Key Takeaways

• Reduce trade size to mitigate liquidity impact and increase the likelihood of a successful transaction on Uniswap
• Increase slippage tolerance (up to 12% typically) to accommodate price fluctuations during trades with low liquidity tokens
• Verify the token being traded to prevent liquidity mismatches and ensure compatibility with Uniswap’s liquidity pools
• Explore alternative DEXes, such as SushiSwap and PancakeSwap, which may offer better liquidity for the desired trade

How AMMs (like Uniswap) work

At the core of Uniswap’s functionality lies the Automated Market Maker (AMM) model, which relies on liquidity pools to facilitate seamless token trading. When you interact with Uniswap (which has a native token, UNI), you’re essentially tapping into these pools, which contain pairs of tokens, such as ETH and USDC.

The AMM determines prices algorithmically based on the ratio of the tokens within the pool, following the constant product formula (x * y = k). This approach is at the core of decentralization because it allows for decentralized trading without traditional order books.

As you dive deeper into the matter, you realize that the depth, or size of the liquidity pool is a vital component. If you attempt to execute a trade that exceeds the pool’s capacity, it will lead to transaction failures.

In such cases, you may encounter errors like “Insufficient Liquidity For This Trade.” Uniswap’s design also allows users to actively contribute to liquidity pools and earn fees from trades executed within the pool. This is called liquidity mining, and it incentivizes participation, which improves liquidity and reduces the likelihood of such errors.

How to Fix “Insufficient Liquidity For This Trade” on Uniswap

When you encounter the “Insufficient Liquidity For This Trade” error on Uniswap, you can take a few steps to resolve the issue.

You can try reducing the trade size to minimize the impact on the liquidity pool, or increase the slippage tolerance setting to give the trade more flexibility.

Additionally, double-check that you’re trading the correct token and consider checking the token’s liquidity on other decentralized exchanges to explore alternative options.

Reduce the trade size

Reducing your trade size is the most straightforward solution to bypass the “Insufficient Liquidity For This Trade” error on Uniswap. By decreasing the amount you’re trying to swap, you lower the impact on the liquidity pool, making it more likely for your transaction to be executed successfully.

It’s simple math. If A must be less than B for a successful transaction, where A is your trade size and B is liquidity pool size, reducing the size of A is a very straightforward and logical solution.

Assess the current liquidity of a trading pair before executing transactions to be able to identify an appropriate trade size that aligns with the pool’s capacity. Reducing trade size helps decrease the likelihood of a failure due to liquidity shortages, but it also reduces potential losses from slippage during execution.

You may need to continually make adjustments to trade sizes based on fluctuations in market conditions and liquidity availability. If something worked today, it doesn’t mean it’ll work tomorrow, and vice versa. Regularly review market conditions and adjust your trade sizes accordingly.

Increase slippage tolerance setting

Your Uniswap transaction’s success may depend on a simple (but important) setting: the slippage tolerance. When you encounter the “Insufficient Liquidity For This Trade” error, consider adjusting this setting.

To do so, access your wallet, connect it to Uniswap, and select the tokens you wish to swap. Then, navigate to the transaction settings and adjust the slippage tolerance.

The default slippage tolerance is automatically set at 0.5% by Uniswap (or 0.1% in Uniswap V3), which means your trade will only get executed if the actual price is within 99.5% or 99.9% of the price you saw on your browser. 

If you manually raise the slippage tolerance, you allow the transaction to execute even if the token price changes more significantly during the trade process due to low liquidity.

For transactions involving lower liquidity tokens, a slippage tolerance setting of 5% to 12% is often recommended. After making the adjustment, confirm the settings and proceed with the transaction.

Increasing the slippage tolerance can significantly reduce the chances of encountering “Insufficient Liquidity for This Trade” errors, as it provides a sort of buffer for price fluctuations. 

Make sure you’re trading the correct token

This one may seem obvious, but this is crypto, and there can be lots of coins with a similar or even the same name as the coin you want to trade. Make sure that you’re trading the correct token. Double-check the token’s contract address, as a small error can result in trading a different token with low liquidity.

Also, be aware of token migrations or updates, as a token may have moved from one liquidity pool to another, affecting its available liquidity.

Of course, you should also confirm that the token you’re trading is supported by Uniswap.

Check the token’s liquidity on other DEXes

When Uniswap’s liquidity is insufficient for your trade, a quick scan of other decentralized exchanges (DEXes) can provide a viable alternative. You can check liquidity metrics on platforms like SushiSwap, TraderJoe or PancakeSwap, as they may offer better trading conditions for the same token pair.

Utilize tools like CoinGecko or CoinMarketCap to assess liquidity depth across various exchanges, helping you identify which DEX has the highest liquidity for your desired trade.

You should also examine the token’s liquidity pools on DEX aggregators like 1inch, which aggregate prices and routes from multiple platforms for optimal trading opportunities. 

Also, you can check the trading volume for the token on other DEXes, as higher trading volume often correlates with better liquidity.

The bottom line

You’ve now got the tools to tackle the “Insufficient Liquidity For This Trade” error on Uniswap and other AMMs. 

You should now understand how AMMs work and be able to apply the fixes – reducing trade size, increasing slippage tolerance, verifying token addresses, and exploring alternative DEXes.

FAQs

How to fix “Insufficient Liquidity For This Trade”?

To fix the “Insufficient Liquidity For This Trade” error on Uniswap or similar DEXes, you can:

1. Reduce Trade Size: Lower the amount you’re trying to swap to lessen the impact on the liquidity pool.
2. Increase Slippage Tolerance: Adjust the slippage tolerance setting to accommodate potential price changes during the transaction.
3. Verify the Token: Make sure that you’re trading the correct token by checking its contract address.
4. Explore Alternative DEXes: If Uniswap’s liquidity is insufficient, consider using other decentralized exchanges like SushiSwap, PancakeSwap, or 1inch.

What is lack of liquidity in trading?

Lack of liquidity in trading refers to a situation where there aren’t enough assets available in a market to fulfill the demand for trades at stable prices. In decentralized exchanges like Uniswap, this can occur when the liquidity pools are too small to handle large transactions. This leads to issues like the “Insufficient Liquidity For This Trade” error.

What causes lack of liquidity?

Lack of liquidity is typically caused by a small or insufficiently funded liquidity pool, where the ratio of assets within the pool cannot support larger trades. 

If you’re encountering a “Swap Failed” error on Uniswap, there are several reasons this might happen. The most common reasons are your slippage settings and not enough funds.

In this article, we will go over the steps that you can take that are likely to solve 99.99% of “Swap Failed” issues on Uniswap.

Key Takeaways

• Adjust slippage tolerance settings to ensure successful trade execution and minimize losses
• Verify wallet balance and be sure you have enough ETH or another chain crypto for gas fees and a sufficient token amount for the swap
• Extend transaction deadlines beyond the default 30 minutes to accommodate network fluctuations
• Monitor network congestion to set appropriate deadlines and fees for timely transactions
• Retry failed transactions after checking and adjusting gas fee and deadline settings

Adjusting Slippage Tolerance Settings

Uniswap – which uses the UNI token for governance and fee payments – is the largest and most used Decentralized Exchanges (DEXes) in crypto, and one of the necessary aspects of navigating Uniswap transactions is managing slippage tolerance settings. These parameters directly influence the success of your swaps. 

The default slippage tolerance on Uniswap is set at 0.5% (and 0.1% for Uniswap V3), which might be too low to be sufficient for tokens with transaction fees.

To avoid failed swaps, try adjusting your slippage tolerance settings. You can adjust the slippage tolerance by clicking the gearbox icon on the Uniswap interface and selecting the “Custom” option. Here, you can input a custom maximum slippage percentage.

For tokens with significant sell fees, you might need to increase the slippage tolerance to at least 1%, and in volatile markets, settings closer to 10%-12% may be necessary. Increase the slippage tolerance incrementally in small percentages to mitigate risks while avoiding excessive price deviations. For example, if 0.5% is too low, don’t immediately go 5%. Start increasing it gradually, first to 1%, then 1.5% and so on. 

This approach helps you get a successful trade execution while minimizing potential losses.

Insufficient Tokens or ETH

If your slippage tolerance settings are in order, the next step is to make sure you have sufficient tokens and ETH (assuming you’re using Ethereum blockchain) to execute the transaction. Check your wallet balance to ensure you have enough ETH to cover the transaction fees.

Of course, if you’re using a different chain, you may need to pay gas fees in a different cryptocurrency. For example, for the BNB Chain you need BNB, for Avalanche you need AVAX, and so on.

Each transaction on Uniswap requires enough crypto to cover gas fees, which may fluctuate based on network congestion. Always verify the current gas prices before initiating a swap to avoid timeouts and enhance transaction success.

Also, confirm that you have the required amount of tokens you intend to swap. Attempting to swap more than your available balance will, of course, give back an error.

If trading a token that has a fee on transfer, make sure to account for that fee in your swap calculation to avoid trading an insufficient amount. Keeping an eye on both token balances and gas fee reserves is necessary, as a lack of either can halt a transaction and result in a swap failure.

Transaction Timeout Issues

Transaction timeout issues on Uniswap can be frustrating, especially when you’re eager to complete a swap. A timeout occurs if the process exceeds 30 minutes, and this will result in an automatic failure of the swap.

To mitigate this, you should adjust the transaction deadline settings to allow for longer processing times during high network congestion.

Here are key points to consider:

• Timeout duration: Uniswap transactions automatically fail if they take more than 30 minutes to complete.
• Adjust transaction deadline: Increase the transaction deadline settings to give your transaction more time to process.
• Increase gas price: Low network fee settings can cause delays. If you increase the gas price, it may help execute transactions promptly.
• Monitor network congestion: Keep an eye on network congestion during peak times to time your transactions better and avoid timeouts.
• Retry after adjustments: If a transaction fails due to timeout, retry after checking and adjusting your gas fee settings.

Other Uniswap Error Types

The K error indicates a Uniswap liquidity pool imbalance, i.e., you attempted a trade which, if executed, would leave the liquidity pool with fewer reserves than expected by the Uniswap protocol. If that happens, the transaction is automatically reverted and won’t go through. 

The INSUFFICIENT_A_AMOUNT and INSUFFICIENT_B_AMOUNT errors occur when there are insufficient input tokens or output amounts for the swap. The TRANSFER_FAILED error typically indicates issues with token contracts or when the transfer function is disabled for the token being traded.

Other errors include EXPIRED, which occurs when transactions take longer than the designated 30-minute deadline, often due to low network fees or high congestion.

The bottom line

To fix a “Swap Failed” error on Uniswap, you should first check your wallet balance to ensure you have enough tokens and transaction fees. Then, adjust your slippage tolerance, especially for volatile tokens, to at least 1% or more if necessary. These two alone should fix the issue 99% of the time. 

Extend the transaction deadline beyond the default 30 minutes and consider increasing the gas price to expedite processing. Lastly, make sure that your token contract approvals are in place. To avoid paying too much fees, you can consider using cryptocurrencies that are cheap to transfer.

FAQs

Why is my swap failing on Uniswap?

A swap on Uniswap may fail due to several reasons. The most common ones include incorrect slippage tolerance settings, insufficient funds to cover the transaction, or network congestion. Another common cause is an imbalance in the liquidity pool for the tokens you’re trying to trade, which can trigger the transaction to be reverted.

What happens if a swap fails?

If a swap fails on Uniswap, the transaction will not go through, and your tokens will remain in your wallet. The network will still deduct a small gas fee for attempting the transaction, but the swap itself will not be executed, meaning no tokens are transferred or exchanged.

How to fix slippage in Uniswap?

To fix slippage issues in Uniswap, you can adjust the slippage tolerance settings in the swap interface. You can do this by clicking the gearbox icon and selecting “Custom” to input a new slippage percentage. If your transaction fails due to slippage, gradually increase the slippage tolerance from the default 0.5% (or 0.1% in Uniswap V3) to a higher percentage until the transaction succeeds. Be cautious not to set it too high to avoid significant price deviations.
