Laika Multichain Bridge

Laika's bridge serves as a critical infrastructure component, acting as the gateway for seamless asset movement and communication between the Laika L2 network and the Dogecoin L1 blockchain. Here's a deeper look at its technical aspects:

1. Multi-Signature Security on L1:

• Due to Dogecoin's lack of native smart contract functionality, the bridge on the Dogecoin blockchain relies on multi-signature addresses for secure fund management. This approach requires multiple parties to approve any bridge transactions, significantly reducing the risk of unauthorized token transfers.

2. Smart Contract Management on L2:

• On the Laika L2 network, a dedicated smart contract acts as the custodian for bridged Dogecoin tokens. This smart contract:

  • Holds and manages the bridged DOGE supply.

  • Facilitates the issuance and redemption of DOGE tokens based on bridge activity.

3. Maintaining Supply Parity:

• Since Dogecoin cannot be natively created on Laika, the bridge enforces a strict 1:1 supply peg between the L1 and L2 networks. This ensures transparency and prevents the unauthorized inflation of DOGE tokens within the Laika ecosystem.

  • Depositing DOGE: When a user deposits DOGE on the L1 network, an equivalent amount is released from the bridge contract on the Laika L2 network.

  • Redeeming DOGE: Conversely, redeeming DOGE on Laika locks the corresponding tokens from the L2 network, maintaining the supply balance.

4. Bridging Beyond Dogecoin:

• Laika's bridge extends its functionality beyond just DOGE. It allows users to bridge verified inscription-based ERC-20 tokens and NFTs created on the Dogecoin blockchain.

  • ERC-20 and ERC-721 Compatibility: These bridged assets are represented as smart contracts on the Laika network, adhering to the ERC-20 and ERC-721 standards, respectively. This enables seamless integration with Laika dApps and wallets.

5. Account Abstraction Integration:

• The bridge plays a vital role in Laika's account abstraction layer. By facilitating communication between user wallets on the L1 network and smart contracts on the L2 network, it empowers users to interact with Laika applications and dApps using their preferred Dogecoin wallets. This eliminates the need for users to manage separate L2 wallets, offering a more convenient and familiar user experience.
