I’m trying to mint a new NFT using Hedera Token Service but I keep running into a signature validation problem. The error message says the signature is not valid even though I think I’m signing it correctly.
I’m following the official documentation but something must be wrong with how I’m creating or formatting the signature. Has anyone else run into this issue when working with HTS for NFT creation? I’m not sure if it’s a problem with my private key, the transaction structure, or maybe how I’m encoding the signature.
Any help would be really appreciated since I’ve been stuck on this for a while now.
I’ve faced similar issues while working with the Hedera Token Service. It’s crucial to ensure that your account ID follows the correct format, which is typically 0.0.xxxx. Additionally, verify that you are using the appropriate network, whether it’s the testnet or mainnet. Another common mistake is related to the permissions of your private key; ensure it has the necessary rights for the NFT you’re trying to mint. These factors are often the culprits behind signature validation errors.
double-check ur using the operator key for signing, not the treasury key - I’ve seen ppl mix those up. also verify ur transaction’s properly serialized before signing. that second one got me before when minting HTS NFTs.
