KEY TAKEAWAYS
- Lido’s stETH and wstETH tokens are now available on Unichain, enhancing cross-chain liquidity for DeFi applications.
- Unichain, developed by Uniswap Labs, uses Optimism’s OP Stack to improve transaction speed and cost efficiency while maintaining Ethereum’s security.
- The Superbridge app facilitates the transfer of stETH and wstETH between Ethereum and Unichain, with a standard security delay for transactions back to Ethereum.
The Lido protocol’s stETH and wstETH tokens are now accessible on Unichain, a DeFi-focused Ethereum Layer 2 blockchain. This development aims to enhance cross-chain liquidity. Unichain, developed by Uniswap Labs, utilizes Optimism’s OP Stack to improve transaction speed and cost efficiency while maintaining Ethereum’s security.
The deployment on Unichain was facilitated using the Lido protocol Multichain Automaton. This script simplifies the deployment of stETH and wstETH bridges on OP Stack networks by employing a reference architecture.
Unichain: A DeFi-Centric Layer 2 Solution
Unichain is an EVM-compatible Layer 2 rollup built using Optimism’s OP Stack. It is part of the Superchain ecosystem and launched as a Stage 1 Rollup. The platform features a fully functioning permissionless fault-proof system that ensures trustless security.
Specifically designed for DeFi and cross-chain liquidity, Unichain plans to leverage Uniswap v4’s capabilities for liquidity provision. The chain supports a robust DeFi ecosystem with over 80 protocols and features 1-second block times. Future plans include implementing 250ms sub-blocks through Rollup Boost to further reduce latency.
Bridging stETH and wstETH to Unichain
The Superbridge app provides a user interface for transferring stETH and wstETH between Ethereum and Unichain. Users must ensure their wallets contain stETH or wstETH before proceeding. The bridging process typically completes in a few minutes, with transaction status trackable on both Etherscan and Uniscan.
Bridging back from Unichain to Ethereum may take up to seven days. This delay is a standard security feature of the OP Stack, serving as a challenge period before finalizing the transaction. Additionally, users can unwrap wstETH into stETH or wrap stETH into wstETH on the Unichain network using Lido’s wrap widget, ensuring efficient token management.
