Metamask Error: “Gas Evaluation Failed” on Uniswap Trading
As a token holder or trader, having issues with alt token buybacks can be frustrating. However, it is not uncommon for users to encounter errors when trying to do so using popular platforms such as MetaMask and Uniswap.
The error message “gas evaluation failed” is often displayed on the MetaMask screen when trying to buy back tokens on Uniswap. This issue has been reported by several users who have struggled to resolve it despite having high liquidity for their alt tokens.
Problem: Gas Evaluation Failed
When using Uniswap, gas evaluation fails due to an underlying issue in the platform architecture or tokenomics. Metamask and Uniswap in particular are built on top of Web3.js, a JavaScript library that provides a set of APIs for interacting with decentralized applications (dApps) and blockchain networks.
To estimate gas costs, MetaMask uses the Gas Estimation API provided by Chainlink Labs. However, it appears that this API is temporarily down or experiencing technical issues.
Impact: Limited Token Purchase
The inability to accurately estimate gas costs means that users are unable to accurately calculate the cost of transactions when buying back tokens on Uniswap with MetaMask. As a result, the process becomes more expensive and time-consuming, resulting in additional fees for both the user and the exchange.
How to fix the problem
Unfortunately, it seems that MetaMask and Uniswap have not yet been able to resolve this issue with official patches or fixes. To work around this issue, users can try the following:
- Wait for an update: As with all technical issues on major platforms like MetaMask and Uniswap, updates are often released over time.
- Use alternative methods: Users may need to explore other options for estimating gas costs or contacting the hub directly.
Warning
Due to the temporary nature of this issue, users should exercise caution when attempting to buy back Uniswap tokens using MetaMask. Using a different wallet or alternative method may help resolve the issue.
We appreciate your patience and understanding in this matter, but it is important to know that technical issues can occur even with the most trusted platforms. We hope that the MetaMask and Uniswap developers can resolve this issue as soon as possible to restore the user experience for all token holders and merchants.
Conclusion
This error is a frustrating reminder of the complexity involved in building decentralized applications on blockchain networks. While it is not uncommon, users should remain vigilant and proactive in seeking solutions when they encounter technical issues, such as failed gas estimation errors with MetaMask and Uniswap.
By staying informed of future community updates and participating in discussions, we can all work together to resolve these issues and ensure a smoother user experience for all parties involved.
