HopeSwap Approve USDT Error
HopeSwap Approve USDT Error
When users operate on HopeSwap, the following exceptions may occur when they need to approve USDT.
Error Cause
The problems mainly occur in the situation of insufficient authorization of USDT, so it is best to use the method of full authorization in the use of authorization.
The USDT approval operation mandates that the initial authorization amount should be set to 0. Any non-zero authorization that continues will result in an error being reported by the contract.
Solutions
(1) Revoke your USDT Approve in HopeSwap (Recommended)
Enter the USDT Write Contract.
Connect your Wallet.
Choose the "approve" method.
"spender" fill in HopeSwap Router address:
0x219Bd2d1449F3813c01204EE455D11B41D5051e9"_value" fill in 0
(2) Using up the remaining amount of USDT
Enter the USDT browser.
Choose the "allowance" method.
"_onwer" fill in your own address; "_spender" fill in HopeSwap Router address:
0x219Bd2d1449F3813c01204EE455D11B41D5051e9
Example: The queried 18357027, and the actual remaining amount is 18.357027 USDT since the data has six decimal places.
Use up the rest balance of the last authorized and re-authorize USDT in HopeSwap.
(3) Use a new wallet address in HopeSwap.
How to avoid this problem
You are suggested to use the "Default Value" when setting the approval amount for USDT to avoid future approval failures.
