When using TronLink to import a private key, ensuring the accuracy of the private key is extremely important; otherwise, you won't be able to access your wallet. Here are some guidelines on private key input:
-
Format Check: Please ensure that your private key only contains hexadecimal format characters, which are the 16 characters from 0-9 and a-f.
-
Length Check: The standard length of a private key is 64 characters. If your private key is shorter than 64 characters, you may need to pad it. Here are specific ways to do it:
1.If the private key length is even, such as 1234 (length 4), you should add zeros to the left of 1234 to get a full 64-bit private key, such as:
0000000000000000000000000000000000000000000000000000000000001234
2.If the private key length is odd, such as 1234567 (length 7), there are two ways to pad the private key:
1）Add zeros to the left of the private key to get a full 64-bit private key, such as:
0000000000000000000000000000000000000000000000000000000001234567
2）Take the first N-1 digits of the private key (where N is the length of the private key), and then add zeros to the left. For instance, if you take the first 6 digits of 1234567, which are 123456, and then add zeros to the left, you get a full 64-bit private key, such as:
0000000000000000000000000000000000000000000000000000000000123456
These rules mainly apply to private keys generated before and after the TronLink plug-in V3.24.0 version. Different versions of private keys might require different padding methods.
