Iolend

In this section, we will introduce the Iolend SDK interfaces, which provide developers with a convenient and efficient way to interact with the Iolend protocol. These interfaces cover various aspects of the protocol, including deposit, withdraw, borrow, and repay. They are designed to be used easily and flexibly.

The following section will introduce the interfaces related to the Iolend protocol, which can be accessed through the api.protocols.iolend. prefix.

      decimals: number;
      symbol: string;
      name: string;
    };

Functions

getDepositTokenList(chainId: number): An asynchronous function that retrieves the list of tokens supported by the Iolend deposit logic on the specified chainId.
