Core Concepts

Lending Protocol Basics

The NAVI lending protocol allows users to:

• Deposit: Deposit assets into pools to earn interest
• Borrow: Use deposits as collateral to borrow other assets
• Repay: Repay loans and pay interest
• Withdraw: Withdraw deposits from pools

Health Factor

Health factor is an important metric for measuring the safety of a user's lending account:

• Health Factor > 1: Account is safe and can continue borrowing
• Health Factor ≤ 1: Account is at risk of liquidation

Flash Loan

Flash loans allow users to borrow assets without collateral, but must be repaid within the same transaction.

Installation

npm install @naviprotocol/lending

Code Style and Conventions

Interface Optional Parameters

The last options parameter of the interface is usually an optional object used to customize interface behavior. Common optional parameters include but are not limited to:

• client: Sui network client instance (such as SuiClient), used for customizing network requests, suitable for scenarios that require custom RPC nodes or multi-network environments.
• env: Specify environment (such as 'prod'、'dev'), affecting data sources and on-chain contract addresses, ensuring data isolation and compatibility in different deployment environments.
• cacheTime: Custom cache time in milliseconds. By setting cache time, you can reduce duplicate requests and improve performance. For example, cacheTime: 60000 means cache for 60 seconds.
• disableCache: Whether to disable cache
• accountCap: In ptb-related operations, use account cap

Usage Recommendations:

• If you don't pass options, the SDK will automatically use default configuration, suitable for most regular scenarios.
• When you need to customize network, environment, or cache strategy, it's recommended to pass corresponding parameters for more flexible control.

Interface Naming

• Interfaces with PTB suffix indicate that the current interface is used for constructing transactions.
