# Debt Bridge

Example of how to move Debt between protocols

**Step 1**

[Installation](https://docs.instadapp.io/installation) or just use your browser console.

**Step 2**

[Setup Account](https://docs.instadapp.io/setup)

**Step 3**

Trigger the following uniquely designed spells to fulfill this use case. Check [this section](https://docs.instadapp.io/cast) for generic details around casting spells.

The DSA will cast the spells across the [MakerDAO](https://docs.instadapp.io/connectors/makerdao/), [Compound](https://docs.instadapp.io/connectors/compound/) and [Instapool](https://docs.instadapp.io/connectors/instapool/) connectors in the specified sequence.

## Maker -> Compound

**Benefits**

* When Borrow rate on Maker > Compound. Pay less interest on your debt.
* Help make DAI stable.

**Recipe**

1. **Instapool**: borrow DAI
2. **MakerDAO**: payback DAI
3. **MakerDAO**: withdraw ETH
4. **Compound**: deposit ETH
5. **Compound**: borrow DAI
6. **Instapool**: return DAI

**Requirements**

* User must have a Maker Vault.
* Be sure to check the borrowing power on Compound to have enough margin from liquidation.

Copy

```
let borrowAmount = dsa.tokens.fromDecimal(200000, "dai"); // 200000 DAI
let dai_address = dsa.tokens.info.dai.address
let eth_address = dsa.tokens.info.eth.address
let vault_id = 0; // User's Vault ID

let spells = dsa.Spell();

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

spells.add({
  connector: "maker",
  method: "payback",
  args: [vault_id, -1, 0, "534"] // max payback and setting the payback amount with id 534
});

spells.add({
  connector: "maker",
  method: "withdraw",
  args: [vault_id, -1, 0, "987"] // max withdraw and setting the withdrawn amount with id 987
});

spells.add({
  connector: "compound",
  method: "deposit",
  args: [eth_address, 0, "987", 0] // get deposit amount with id 987
});

spells.add({
  connector: "compound",
  method: "borrow",
  args: [dai_address, 0, "534", 0] // get borrow amount with id 534
});

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

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

## Compound -> Maker

**Benefits**

* When Borrow rate on Maker < Compound. Pay less interest on your debt.
* Help make DAI stable.

**Recipe**

1. **Instapool**: borrow DAI
2. **Compound**: payback DAI
3. **Compound**: withdraw ETH
4. **MakerDAO**: deposit ETH
5. **MakerDAO**: borrow DAI
6. **Instapool**: return DAI

**Requirements**

* User must have a Maker Vault. If not, [create a new vault](https://docs.instadapp.io/connectors/makerdao#open) in the same transaction itself.
* Be sure to check the borrowing power on MakerDAO to have enough margin from liquidation.

```

let vault_id = 0; // User's Vault ID

let spells = dsa.Spell();

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

spells.add({
  connector: "compound",

  args: [dai_address, -1, 0, "692"] // max payback and setting the payback amount with id 692
});
