The BNB Chain ecosystem is undergoing a pivotal transformation with the retirement of the BNB Beacon Chain and the full migration of its functionalities to the BNB Smart Chain (BSC). This strategic shift, known as BNB Chain Fusion, marks a new chapter in network efficiency, security, and scalability. By consolidating operations onto a single chain, BNB Chain aims to streamline development, reduce complexity, and enhance the overall user and validator experience.
This guide provides a comprehensive overview of the migration process, covering key benefits, timelines, and actionable steps for validators, delegators, token issuers, and holders.
Why the BNB Beacon Chain Is Being Retired
Originally designed as a staking and governance layer to complement BSC, the BNB Beacon Chain has become increasingly redundant due to evolving blockchain architecture and the discontinuation of order-book-based DEXs under BEP151. Its reliance on a cross-chain bridge with BSC introduced development overhead and potential security vulnerabilities.

With native staking and governance now fully operational on BSC following the Feynman Hardfork, maintaining two parallel chains no longer aligns with BNB Chain’s vision for efficiency and decentralization. The fusion initiative eliminates fragmentation, paving the way for a more secure and scalable ecosystem.
Key Benefits of Migrating to BNB Smart Chain
Streamlined Development and Network Efficiency
By consolidating all core functions—staking, governance, and validator management—onto BSC, development efforts are unified. This eliminates duplicated work, accelerates feature deployment, and fosters a more cohesive developer environment.
Enhanced Security Through Simplified Architecture
Retiring the Beacon Chain removes the cross-chain bridge attack surface, reducing potential exploits. A single-chain model simplifies consensus mechanisms and improves resistance to network-level threats.
Implementation of Proposer-Builder Separation (PBS)
To address growing concerns around Maximal Extractable Value (MEV), BNB Chain is implementing Proposer-Builder Separation (PBS) on BSC. This innovation creates a transparent blockspace marketplace, preventing MEV centralization and ensuring fair transaction inclusion for all participants.
Optimized Staking Ecosystem with LSDFi Integration
The migration unlocks advanced staking capabilities through Liquid Staking Derivatives and DeFi (LSDFi) integration. Validators and delegators gain access to flexible financial tools that improve capital efficiency, increase reward potential, and deepen liquidity across DeFi protocols.
Migration Timeline Overview
The BNB Chain Fusion rollout follows a structured, multi-stage plan to ensure a smooth transition:
- Prerequisite Phase
BEP2/BEP8 asset holders must transfer assets to BSC before migration deadlines. Stage 1 – April 2024
- Asset issuance on Beacon Chain halted
- Validator management and governance moved to BSC
- Atomic swap function disabled on April 15, 2024
Stage 2 – May 2024
- Governance and delegation deactivated on Beacon Chain
- All assets undelegated and returned to user wallets
Stage 3 – May 2024
- Cross-chain communication between Beacon Chain and BSC disconnected
- Beacon Chain halted and data archived
Stage 4 – June 2024
- Token migration tool launched to recover any stranded funds on Beacon Chain
For complete details, refer to the official BNB Chain Fusion Roadmap.
What Validators Need to Do
With native staking now live on BSC via BEP294, validators previously operating on the Beacon Chain must migrate to remain active.
Step 1: Create a New Validator on BSC
Use the Staking Dapp to set up your new validator directly on BNB Smart Chain. Follow the validator creation guide carefully, ensuring all fields—especially the Identity field—are correctly populated.
Step 2: Migrate Stakes from Old Validator
Once your new validator is active:
- Notify your delegators about the migration
- Guide them to re-delegate their stakes to your new validator address
For detailed instructions, consult the stake migration guide.

What Delegators Should Know
Under BEP333: BNB Chain Fusion, delegators must migrate their stakes to participate in the new native staking system on BSC. Two primary migration paths are available:
- Cross-Chain Redelegation via the BC delegation portal
- Undelegate → Transfer → Re-delegate using cross-chain transfer tools
For BEP153-format delegations, follow the dedicated BEP153 migration guide.
Why Migrate Now?
- Fast & Simple: Takes just minutes to complete
- Higher Staking Rewards: New BSC validators offer significantly better APY than legacy Beacon Chain validators
- Airdrop Eligibility: Migrated delegators can qualify for rewards through the Airdrop Alliance
Delaying migration risks missed rewards and potential exclusion from future network participation.
Guidance for BEP2 Token Issuers
Token binding ensures seamless circulation of assets between Beacon Chain and BSC with verified total supply.
After the final sunset hardfork:
- Bound tokens: Can still be recovered using the official token recovery tool
- Unbound tokens: Will be permanently unrecoverable
Issuers must:
- Confirm if their tokens support cross-chain transfers using the asset verification tutorial
- If not bound, use the Token Bind Tool to deploy a BEP20 version on BSC
- Notify holders promptly via multiple channels to ensure timely migration
Failure to act may result in irreversible asset loss for users.
What BEP2 Token Holders Must Do
All BEP2/BEP8 asset holders—including those with BNB, BTC, or other tokens—must migrate their assets to BNB Smart Chain before June 2024.
Critical Reminder:
Failure to migrate by the deadline will result in irreversible asset loss.
Most major BEP2 tokens can be transferred 1:1 to BSC without restrictions. Use trusted methods such as:
- Direct cross-chain transfer via official tools
- Centralized exchanges (e.g., Binance.com)
- Decentralized platforms like THORSwap

Frequently Asked Questions (FAQ)
Q: What happens if I don’t migrate my staked BNB?
A: If you don’t migrate, your delegation will be undelegated automatically during Stage 2. However, you’ll miss out on higher APY opportunities and airdrop rewards available only to participants in the new native staking system.
Q: Can I still access my funds after the Beacon Chain shuts down?
A: Yes—but only if you use the official token recovery tool before or shortly after shutdown. Unmigrated or unbound assets may become permanently inaccessible.
Q: Is there a cost associated with migration?
A: Standard gas fees apply when transferring assets or creating validators on BSC. There are no additional charges imposed by the BNB Chain team for migration.
Q: Do I need technical expertise to migrate?
A: Basic blockchain knowledge helps, but user-friendly tools like the Staking Dapp and delegation portal simplify the process for non-technical users.
Q: Will the BNB token change during this process?
A: No. The underlying BNB asset remains unchanged. Only its network location (from Beacon Chain to BSC) is updated during migration.
Q: Where can I get help if I encounter issues?
A: Visit the official BNB Chain documentation hub or join community forums for support from developers and experienced users.
