Wallet updates:

After introducing native Ethereum support to HEAT wallet allowing you to use your HEAT master key as a parent key for your Ethereum addresses, we now present native Bitcoin support to HEAT wallet. Supported are Bitcoin private keys as well as BIP44 compatible seeds.

To assist users downloading and setting up your own copy of HEAT wallet in order to store and handle your HEAT, Bitcoin or Ethereum we introduce this first part of Getting Started With HEAT Wallet (https://github.com/Heat-Ledger-Ltd/heat-ui/blob/master/docs/GETTING_STARTED.md), please check it out.

In addition to Bitcoin support, the following updates were made to the wallet:

Server updates:

The HEAT 2.5.2 Server is an optional update, it mostly aggregates completed improvements and a number of bug fixes.

An improvement deserving special mention - we’ve added a new dialect to the peer 2 peer communication protocol (how servers talk amongst each other). Only new servers using the 2.5.2 version are capable of using this more advanced protocol. When your server talks to older servers the old dialect will be used.

The new communication protocol is based on https://avro.apache.org/ instead of https://www.json.org/. HEAT has added full fledged AVRO encoding and decoding support to both the core HEAT server as well as the SDK https://github.com/Heat-Ledger-Ltd/heat-sdk (sdk = native browser + nodejs libs).

With AVRO enabled you can expect a ~3-5 times network traffic reduction.

The biggest boost however is its CPU usage. Especially on high loads the amount of memory used and CPU power needed drops from significant to almost non existent. Both encoding and decoding happens up to 100s of times faster than before.

Other notable updates to the server code:

Other notable updates:

HEAT-SDK (software development kit - browser+server) was promoted to version 1.0.1 recently and is becoming an ever more important part of our arsenal and a vital building block of our own and third party projects.


We implemented a mini Paper Wallet utility which assists you to store and administer your private keys. It is functional as is with one drawback: the generated keys are old style HEAT keys which means you can’t derive Bitcoin or Ethereum addresses from them. You CAN however create paper wallets with your BIP44 compatible keys you created in the main HEAT wallet.
