Operations
Lending DAI  
In Assets: DAI    Out Assets: CDAI
A lender supplies DAI to the protocol and receives CDAI tokens in exchange (IOU tokens). Based on demand and supply of DAI in the market, functions of the compound protocol will calculate the interest accrued for all those issued CDAI tokens. 
JavaScript & Node
const operation = new defire.Operations.Compound.Lend.DAI({
  amountDAI: "5000000000000000000" //5 DAI
});
Constructor object fields
amountDAIrequired string | number | JSBI​
Amount of DAI to lend in wei format
Returns
Creates a new operation object
​
Redeem DAI
In Assets: CDAI    Out Assets: DAI
A lender returns CDAI to the protocol and receives in exchange DAI that includes the interest accrued. 
JavaScript & Node
const operation = new defire.Operations.Compound.Redeem.DAI({
  amountCDAI: "5000000000000000000" //5 CDAI
});
Constructor object fields

Total number of CDAI to return in wei format
Returns
Creates a new operation object
​

Returns
Creates a new operation object
​
Lending USDC  
In Assets: USDC    Out Assets: CUSDC
