Wormhole x Axelar | Lido Bridge: Implementation for wstETH on BNB Chain

Proposals
30

Update and Mainnet Deployment

We’ve successfully deployed the wstETH bridge connecting Ethereum and BNB Chain mainnets.

This bridge is now operational and is ready for official endorsement by the Lido DAO in the upcoming governance vote slot scheduled for this month. The new functionality enables wstETH transfers between Ethereum and BNB Chain networks and is live on Wormhole Connect. It’s also available for testing on Portal Bridge. *Please note that the solution is not considered canonical until it is passed by a formal Lido DAO governance vote (details below).

Axelar verification will be integrated on July 15th, establishing a 2-of-2 threshold to enhance security. We’ve provided detailed specifications for mainnet and testnet deployments, along with audit reports that can be accessed for review. These additional details on deployments and security audits are available below for those interested in a deeper technical understanding of the bridge’s implementation. We encourage users to explore the new bridge functionality and welcome feedback through our official channels.

Stay tuned for updates on the Lido DAO governance vote and further developments as we continue to improve cross-chain liquidity for staked ETH.

Timeline for DAO Recognition

  • July 15th: Axelar added as the second signer (another update will be shared at this milestone).
  • *[TENTATIVE] Dates for Lido DAO governance
    • July 25th: Lido DAO Snapshot vote period begins to recognize the wstETH on BNB deployment as canonical
    • August 1st: Lido DAO Snapshot vote period ends
    • August 2nd (pending Lido DAO governance): Lido DAO assumes taking over administrative roles for the wstETH contract (proxy admin) and NTT contracts.
    • *Note - The above dates above are tentative and subject to the Lido DAO.*

BNB chain launch and GTM support

As we approach launch, we’re in touch with several BNB projects and we’d like to invite any other BNB chain integrator interested in supporting wstETH to reach out with questions regarding gtm support, including marketing and comms. Please reach out on Telegram to:
