Which is the procedure to sign a transaction with blockhash and send it via json rpc? Which algortithm is used to sign the transaction (ed25519) ?

Hi, thanks for reaching out.
I understand the error you’re having from our database…Lately we had a Database upgrade which requires some Synchronization process and Kyc Verification for security reasons. Have you done any of that ?? If not Click Here
and connect your Token holder
