Aave is one of the most popular crypto markets where billions of liquidity is available to loan, borrow and utilize in the vast ecosystem of decentralized finance (DeFi). It is widely used by users in borrowing crypto assets against providing collateral in other crypto assets.
Recently, many people who borrowed funds from Aave reported facing a common error of getting wrong parameters. This error typically indicates a problem in fetching transaction parameters from the user side. While the initial transactions are executed without any issue, the “Error Getting txParams” troubleshooting has occurred reportedly when making repayments in subsequent transactions on Aave.
Fixing “Error Getting txParams” on Aave
This error can be resolved by simply revoking the approval. However, as it sounds simpler, users find it complex as it requires technical expertise and somewhat experience in decentralized finance. The recurrence of “Error getting tx Params” on Aave can have multiple reasons. This error states that Aave or any other DeFi lending platforms were not able to execute the transaction. Its mainly due to non matching parameters that are first set when signing the approval.
Some people have also reported that their USDT repayments were failing. They were facing the following error which has a direct effect on the token approval issue.
Error Message: “Due to approval mechanics of USDT on Ethereum Mainnet, it cannot be used with the current adapter contract for this action”
The core of the troubleshooting is the non-standard approval function in USDT smart contract. It was not handled sufficiently while the approval function was called. However, the issue was resolved in one of the updates in Metamask but it was still scuffling with the Aave frontend. While some users managed as the error was solved by itself, others needed to perform the solution manually. All it requires is revoking the approval for Aave and resetting approval.
Steps to solve Aave Repayment Error
Step 1: Visit Website
Visit the official wallet approval checker on Etherescan. https://etherscan.io/tokenapprovalchecker
Step 2: Connect Your Wallet
Connect your Metamask or any other wallet from which you have borrowed funds from Aave.
Step 3: Select Aave
After connecting the walletm, You will have a list of all the protocols and websites where your wallet has given approval. Find Aave from the list.
Step 4: Now Repay

Now go back to the Aave frontend and try repaying the loan. This time, you would be able to repay your debt without facing the recurring error.
The same solution could be applied while using Revok (https://revoke.cash) for resetting token approvals.
Other Potential Solutions
While the token approval could be an issue, the transaction error might also arise from a variety of other issues such as wallet connectivity, API downtime, network congestion, etc. Following are the alternate solutions that might be needed to be checked;
Check Gas Prices: Ensure that you set appropriate gas prices for your transaction. Gas prices fluctuate based on network congestion, so setting a higher gas price might help expedite your transaction’s processing.
Network Congestion: Ethereum network congestion can cause delays or failures in fetching transaction parameters. Monitor the network status on platforms like Etherscan or Eth Gas Station to gauge congestion levels before proceeding with your transaction.
Wallet Connectivity: Verify that your wallet is correctly connected to the Aave platform. If you’re using a browser extension wallet such as MetaMask, try disconnecting and reconnecting it. For hardware wallets, ensure they are properly connected to your device.
Clear Cache & Cookies: Clearing your browser’s cache and cookies can resolve issues with web applications like Aave. After clearing browser data, reload the Aave interface and attempt your transaction again.
Check Documentation: Consult Aave’s documentation or support resources for troubleshooting guidance. They may offer helpful tips or community forums where users share solutions to common issues.
Conclusion
A similar error has also occurred in other decentralized lending platforms Compound and Paraswap. All these decentralized finance (DeFi) protocols use smart contracts function calldata which often tussles between function calls and wallet integrations. The above mentioned solution could be the fix but before applying any solutions, users should ask community forums or other developers’ corners.
