Aave is a leading cryptocurrency marketplace with billions of dollars of liquidity, enabling lending, borrowing, and spending within the decentralized finance (DeFi) ecosystem. It is popular for borrowing crypto assets by using other cryptocurrencies as collateral.
Recently, some borrowers on Aave have reported a recurring issue with “Failed to get txParams”. This error typically indicates an inability to retrieve transaction parameters on the user’s side. While the first transaction goes smoothly, users encountered this error especially when trying to repay in subsequent transactions on Aave. We have fixed “Failed to get txParams” on Aave. This issue can be resolved by revoking the permissions. This may seem easy at first glance, but users often find it difficult because decentralized finance requires technical knowledge. If you are experiencing “Failed to get txParams” repeatedly on Aave, there could be various reasons. It indicates that Aave or other DeFi lending platforms were unable to execute the transaction due to a mismatch in parameters initially set during authorization. In addition, users have reported issues especially with repayment of USDT, which directly affects the token’s authorization process.
Error message: “Due to the authorization mechanism of USDT on Ethereum mainnet, this action is not available in the current adapter contract.” The bug fix revolved around a non-standard authorization feature within the USDT smart contract that was not properly managed. It became the authorization process. The issue was resolved with an update to Metamask, but some users continue to experience issues with the Aave frontend. Some users noticed that the error was automatically fixed, while others had to manually revoke and reset Aave’s permissions.

Other possible solutions:
While token authorization can play a role, transaction errors may also arise from various other issues, such as wallet connectivity problems, API downtime, or network congestion. To address these, consider the following additional steps:
1. Check your gas price: Make sure you set the correct gas price for your transaction. Gas prices fluctuate depending on network activity. Setting a higher gas price will speed up transaction processing.
2. Monitor network congestion: Congestion on the Ethereum network can cause delays and errors in retrieving transaction parameters. Before proceeding with the transaction, use a platform such as Etherscan or Eth Gas Station to get an idea of the network status.
3. Check your wallet connection. Make sure your wallet is properly connected to the Aave platform.
If you are using a browser extension wallet such as MetaMask, try disconnecting and reconnecting. If it is a hardware wallet, make sure it is properly connected to your device.
4. Clear cache and cookies: Troubleshoot web applications such as Aave by clearing your browser cache and cookies. After deleting them, reload the Aave interface and trade again.
5. Refer to documentation: For troubleshooting guidance, refer to Aave’s documentation or support resources. They may provide helpful tips or a community forum where users discuss and resolve common issues. In summary, similar bugs have been reported in other decentralized lending platforms such as Compound and Paraswap. Because these DeFi protocols use function call data from smart contracts, conflicts may occur between function calls and wallet integrations. While the above solutions may resolve the issue, we recommend seeking advice from the community forum or developer community before implementing a fix. Reading other articles, such as our article on DeFi Lending Explained, can help you gain a comprehensive understanding of the theoretical framework of DeFi lending.
