How We Achieve Cross-chain Capability

Mbel Finance introduces a modular cross-chain architecture built around a Origin Chain, a Messaging Layer, and Destination Chains.

The Origin Chain, Etherlink, serves as the core of the protocol. It stores all liquidity, manages lending and borrowing logic, and acts as the source of truth for user positions and protocol state. As a fast and low-cost optimistic rollup, Etherlink enables near-instant transactions and significantly reduces gas costs, providing an optimal base layer for Mbel Finance’s operations.

Cross-chain communication is powered by Hyperlane, a permissionless messaging protocol. Hyperlane ensures reliable and secure message delivery across chains without relying on centralized bridges. It handles the dispatch, transport, and verification of messages from Etherlink to other supported chains.

Destination Chains, such as Arbitrum Sepolia and Base Sepolia, do not hold protocol state or execute business logic. Instead, they act as endpoints where user balances are updated based on instructions from the Origin Chain. This separation enables scalability and modularity without duplicating core logic across chains.

When users perform actions such as borrowing or redeeming assets, the transaction is processed on Etherlink. Hyperlane then transmits the result to the appropriate Destination Chain, which reflects the outcome in the user's wallet or interface. This cross-chain interaction ensures consistency while maintaining performance and decentralization.

Mbel Finance's architecture enables permissionless lending and borrowing with fast cross-chain settlement, made possible by Etherlink’s performance and Hyperlane’s messaging capabilities.

Mbel Finance supports cross-chain interactions by using Hyperlane, a permissionless interoperability protocol that enables communication between different blockchains.

Through Hyperlane, users on any supported chain can interact with Mbel Finance’s lending protocol, even though the main logic and state reside on the Etherlink testnet.

How it Works:

• Users initiate actions from any supported chain.

• These actions are sent across chains using Hyperlane’s messaging system.

• Hyperlane securely forwards the request to Mbel’s core protocol on Etherlink.

• The protocol processes it and, if needed, sends a response back to the user’s origin chain.

This allows users to interact seamlessly with Mbel from multiple chains, while keeping security and consistency centralized on Etherlink.
