According to the official announcement: The BNB Beacon Chain is nearing its final sunset, with validators agreeing to stop running by mid-November. As of that time, the BNB Beacon Chain will no longer process transactions. This transition is part of the BNB Chain Fusion, a strategic move aimed at integrating BNB Beacon Chain’s functions with the BNB Smart Chain (BSC). The goal is to enhance efficiency, reduce security risks, and align with future technological advancements.

To avoid irreversible losses, BNB Beacon Chain asset holders and centralized exchanges (CEXs) must take immediate action.

Actions for BNB Beacon Chain Asset Holders

  • Migrate BEP-2 and BEP-8 assets: Asset holders are urged to transfer their tokens from BNB Beacon Chain to BSC immediately. Transfers can be done via centralized or decentralized exchanges, or wallets.

  • Potential Risks: Assets that are not migrated may be permanently lost after the Beacon Chain shutdown. Most assets have already been transferred, but any remaining ones should be moved promptly.

Actions for Centralized Exchanges (CEXs)

  • Disable Deposits: CEXs should immediately halt deposit functions for the BNB Beacon Chain.

  • Consolidate BEP2 Assets: CEXs must consolidate BEP2 assets into secure cold wallets before the shutdown.

  • Consequences of Inaction: Failing to gather all tokens from user deposit addresses will lead to recovery difficulties and possible asset loss.

Post-BC Fusion Historical Data Access

  • Blockchain Data: Historical blockchain data will still be available through RPC nodes, snapshots, and the mainnet explorer.

  • Balance Snapshots: A snapshot of user balances will be taken at a specific block height post-fusion, allowing users to verify balances.

  • Token Migration: A recovery tool will be available for migrating assets post-sunset, but assets without cross-chain functionality will be permanently lost.

For further details on migration steps, refer to the official migration guide or the BEP 333 proposal. Both asset holders and exchanges must act quickly to ensure a smooth transition and avoid any asset loss during the BNB Chain Fusion process.
