# Resolvers

Resolvers functions for Protocols & balances. These function will provide you all the essential protocol details to move forward with the integration. Details like:-

## Balances

### .getBalances()

Get the balances for the tokens of a specific Ethereum address.

```js
dsa.balances.getBalances(address, type)
  .then(data => {
    return data
  })
  .catch(error => {
    return error
  })
```

### Parameters
`address` (optional) - An ethereum address. Eg:- "0xa7...3423". Default:- DSA address selected at the time of setup.
`type` (optional) - Balances of what type of tokens. Default:- "token". List of types of tokens currently available:-
* "token" - Normal Tokens. Eg:- ETH, DAI, USDC, etc.
* "ctoken" - Compound interest bearing CTokens. Eg:- CETH, CDAI, CUSDC, etc.
* "all" - Get Balances of all the tokens in the list.

### Returns
`List` of tokens, where the key is the symbol and the value is the formatted balance {eth: 2, dai: 50.1}


## MakerDAO

### .getVaults()

Get all the vaults details needed for address in one call.

```js
dsa.balances.getVaults(address)
  .then(data => {
    return data
  })
  .catch(error => {
    return error
  })
```

### Parameters
`address` (optional) - An ethereum address. Eg:- "0xa7...3423". Default:- DSA address selected at the time of setup.

### Returns
`List` of all things Compound. Eg:-
* `owner` - Owner of the Vault. Same as address parameter.
* `colName` - Collateral type. Eg:- ETH-A, BAT-A, USDC-A, etc.
* `token` - Collateral token. Eg:- ETH, BAT, USDC, etc.
* `col` - Collateral Deposited.
* `debt` - DAI Borrowed.
* `liquidatedCol` - Remaining colletral after Vault got liquidated. (unlock collateral - still in vault but not being used as collateral)
* `rate` - Borrow APY.
* `price` - Collateral Token Price from Maker's oracle.
* `status` - Debt / Collateral ratio.
* `liquidation` - Point at which vault will break. When `status` > `liquidation` vault breaks.
* `urn` - Vault Ethereum address.

dsa.balances.getBalances(address, key)
  .then(data => {
    return data
  })
  .catch(error => {
    return error
  })
```

### Parameters
`address` (optional) - An ethereum address. Eg:- "0xa7...3423". Default:- DSA address selected at the time of setup.
`key` (optional) - key for the object is it going to return. Default:- "token". Eg:- {eth: {...}} or {ceth: {...}} or {"0x..23": {...}}. List of key available.
* "token" - key as underlying token symbol of ctoken. For ceth it's eth. Eg:- {eth: {...}}
* "ctoken" - key as ctoken symbol. Eg:- {ceth: {...}}
* "address" - key as underlying token address of ctoken. Eg:- {"0x...24": {...}}

### Returns
`List` of all things Compound. Eg:-
* `priceInEth` - Tokens price from Compound oracle contracts. Prices are w.r.t "ETH" not "USD".
* `exchangeRate` - CToken to token conversion rate. `CToken balance` * `exchangeRate` = `token balance`.
