Flux: Migration to the HD Wallet (BIP-44)

Step-by-step guide for FluxNode operators

Introduction

Summer 2025 marks a turning point for the Flux ecosystem:

End of Proof-of-Work mining,
Shift toward infrastructure and services,
And most importantly, the rollout of a new HD Wallet (BIP-44).

This guide will help FluxNode operators migrate from the legacy wallet to the new HD system, safely and efficiently.

⚠️ Security Warning

🚨 Always download Zelcore only from the official website:
👉 https://zelcore.io

Fake wallets are circulating and may drain your funds.
Never install Zelcore from any unverified source.

🆕 Before You Begin

Download Zelcore from the official site and update to version V8.19.1 (as of this writing).
Log in once with your legacy credentials, as usual.
→ This allows you to access your legacy masternodes before starting the migration.

Why a New Wallet?

Legacy wallet:

Managed each address independently.
Limited compatibility with external wallets.
Relied on an encrypted file + login credentials.

HD Wallet (BIP-44):

One seed phrase (BIP-39) restores all addresses.
Clear hierarchical structure (BIP-44).
Compatible with Ledger, Trezor, MetaMask, Keplr, and more.

Implications for FluxNode Operators

Legacy addresses are not automatically integrated into the HD Wallet.
Collateral transfer is required to migrate a node.
Parallel Assets (PA) must be claimed before migration.

Critical Case: Unclaimed Parallel Assets

Unclaimed PAs remain tied to your legacy address.
After migration, you will not be able to claim them from the HD Wallet.
Only solutions: restore the legacy address or use flux-cli claimall.

👉 Recommendation: Claim 100% of your PAs before removing your nodes.

🛠️ Migration Steps (Legacy → HD)

1️⃣ Backup the legacy address

Export the private key or keep the encrypted wallet file + credentials.

2️⃣ Remove the node

In Zelcore: Apps > FluxNodes > Remove.
This action releases the collateral.

3️⃣ Create the HD wallet

Log out of the legacy session.
Reconnect via the HD system (BIP-44).
Create your HD wallet and back up your seed phrase securely.

4️⃣ Transfer the collateral

Two possible methods:
- Import the legacy private key into the new Zelcore.
- Or reconnect to your legacy wallet session and transfer directly.
⚠️ Important: After node removal, FLUX collateral may take some time to be fully released.
- Some UTXOs may unlock immediately, but others might require several minutes before they can be moved.
Once available, send the required amount (e.g., 1000 FLUX) to a dedicated HD address.

5️⃣ Recreate the node

In Apps > FluxNodes.
Assign the HD address.
Configure the server via Flux Toolbox.

6️⃣ Verify

Wait for network confirmation.
Monitor status and rewards.

🗒️ Migration Checklist

All PAs claimed.
Legacy keys backed up.
Collateral transfer planned.
Post-installation verification done.

Migration with Snow-Fall.io
