Bitlayer Network EVM Bridge Migration Announcement
10 May 2025
Dear Bitlayer Community Users,
To further enhance the performance and stability of the official EVM cross-chain bridge service on Bitlayer Network, Bitlayer will upgrade and adjust the underlying cross-chain protocol. The current Polyhedra-zkBridge protocol will be replaced with the Chainlink CCIP protocol.
Accordingly, we will perform liquidity migration for tokens in the bridge contracts.
Migration Details:
- Estimated Migration Time: May 10, 2025, 8:00–9:00(UTC+0)
- Original Ethereum-Side Bridge Contract (Liquidity Pool) Address:
- 0xA4252F2A68b2A078c86E0569eB7Fb872A37864AF
- New CCIP Token Pool Addresses:
- USDT Token Pool: 0x9373ab449D2FB2b4f8DE0A97C209195c4E83ACCe
- USDC Token Pool: 0xc2e3A3C18ccb634622B57fF119a1C8C7f12e8C0c
- wstETH Token Pool: 0xA586a732394A1AFfCF15b972cd47C936033C9FA7
- WETH Token Pool: (Pending)
Please pay close attention to the address changes to avoid asset misdirection. All assets in the original address will be securely transferred by the Bitlayer team—no action is required from users. Assets on Bitlayer Network will not be affected.
About the Launch of the New Cross-Chain Bridge Service
The Bitlayer Network EVM Cross-Chain Bridge will reopen after migration and completion of necessary security verification. The expected launch time is before May 12, 2025 (UTC+0).
The tokens launched this time are: USDT, USDC, and wstETH. The launch time for WETH will be announced separately.
We apologize for any inconvenience this may cause and thank you for your continued support and understanding.
