Trigger the following uniquely designed spells to fulfill this use case. Check this section for generic details around casting spells.

The DSA will cast the spells across the Compound and OasisDEX connectors in the specified sequence.

DAI Lending -> USDC Lending

Benefits

• When DAI > $1. Arbitrage benefit due to price difference of DAI & USDC.
• Help make DAI stable.

Recipe

1. Instapool: borrow DAI
2. OasisDEX: Swap DAI for USDC
3. Compound: deposit USDC
4. Compound: withdraw DAI
5. Instapool: return DAI

Requirements

• User must have some DAI deposited.

let borrowAmount = 20; // 20 DAI
let borrowAmtInWei = dsa.tokens.fromDecimal(borrowAmount, "dai"); // borrow flash loan and swap via OasisDEX

let slippage = 0.1; // 0.1% slippage.
let dai_address = dsa.tokens.info.dai.address
let usdc_address = dsa.tokens.info.usdc.address

let buyAmount = await dsa.oasis.getBuyAmount("USDC", "DAI", borrowAmount, slippage);

let spells = dsa.Spell();

spells.add({
  connector: "instapool",
  method: "flashBorrow",
  args: [dai_address, borrowAmtInWei, 0, 0]
});

spells.add({
  connector: "oasis",
  method: "sell",
  args: [usdc_address, dai_address, borrowAmtInWei, buyAmount.unitAmt, 0, "423"] // setting USDC amount with id 423
});

spells.add({
  connector: "compound",
  method: "deposit",
  args: [usdc_address, 0, "423", 0] // get Deposit amount with id 423
});

spells.add({
  connector: "compound",
  method: "withdraw",
  args: [dai_address, borrowAmtInWei, 0, 0]
});

spells.add({
  connector: "instapool",
  method: "flashPayback",
  args: [dai_address, 0, 0]
});

dsa.cast(spells).then(console.log)
