+
+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.
+```js
+{ '7903':
+  { owner: '0x981C549A74Dc36Bd82fEd9097Bc19404E8db14f3',

+  { ... } ...
+}
+```
+
+### .getCollateralInfo()
+
+Get all the Collerals details needed in one call.
+
+```js
+dsa.balances.getCollateralInfo()
+  .then(data => {
+    return data
+  })
+  .catch(error => {
+    return error
+  })
+```
+
+### Returns
+`List` of all Maker's Collateral Types. Eg:-
+* `ETH-A'` - Collateral Name. Eg:- ETH-A, BAT-A, USDC-A, etc.
+* `token` - Collateral token. Eg:- ETH, BAT, USDC, etc.
+* `rate` - Borrow APY.
+* `price` - Collateral Price from Maker's oracle.

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