🔑Contract Specs

Cluster's architecture, highlighting its core contracts and summarizing user actions like supply, borrow, and repay across chains.

Overview

Cluster is built with a modular architecture combining Compound-style market mechanics with cross-chain execution powered by Stargate. The protocol uses a custom-built smart contract called Cross-Chain Lending Gateway (CLG) that manages secure and gas-efficient remote procedure calls between chains.

Cluster's lending logic relies on the Compound V2 model, including Comptroller and Unitroller, and employs a dynamic interest rate model called JumpRateModelV2 to optimize capital efficiency.

Main components

1. CLG (Cross-Chain Lending Gateway): Handles all cross-chain logic, translating user actions from one chain to another.

2. Comptroller and Unitroller: Core governance and risk management contracts adapted from Compound V2.

3. cTokens: Interest-bearing tokens representing user deposits.

4. JumpRateModelV2: Interest rate model that dynamically adjusts borrow and supply rates based on pool utilization.

Key user actions

• Supply assets on Chain A and borrow on Chain B.

• Repay a loan on Chain B from Chain A.

• Redeem supplied assets across chains.

These actions are routed through the CLG and Stargate to maintain atomicity and security.
