We have released two new endpoints for preparing token transfers as part of our Blockchain Tools:

• Prepare A Fungible Token Transfer From Address  
• Prepare A Non-Fungible Token Transfer From Address 

Using these two separate endpoints, customers can prepare transfers for fungible and non-fungible tokens from an address with private and public keys. The address doesn’t have to belong to a wallet. The response will include the transaction fee in Wei.

What else is new:

• In the endpoint New Reverted Block we’ve added UTXO protocols as possible values. 
• In the responses of List Confirmed Transactions By Address and Get Transaction Details by Transaction Id endpoints "contract" and "input" are now optional.
• In the Prepare A UTXO-Based Transaction From HD Wallet (xPub, yPub, zPub) endpoint, the “replaceable” has been made optional (previously required) in all places.
  

Technical documentation updates:

We’ve added additional information on the paginated and list based endpoints and we’ve updated the values for API requests. 

We've also updated our Key Management System (KMS) on GitHub.
