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

  • Zelcore updated (V8.19.1).
  • All PAs claimed.
  • Legacy keys backed up.
  • Collateral transfer planned.
  • Post-installation verification done.

Migration with Snow-Fall.io

➡️ Snow-Fall.io will begin migrating users’ FluxNodes starting August 20, 2025.
This operation will be done in close collaboration with each client to ensure:

  • Secure backups,
  • Complete PA claims,
  • Fast and safe node re-deployment.

Conclusion

Migrating to the HD Wallet (BIP-44) is a necessary step for the future of Flux.
When properly executed, it provides:

  • Enhanced security,
  • Broader compatibility,
  • Easier node and wallet management.

Snow-Fall.io will guide you through this transition with step-by-step support.
