# tronWeb.contract() <TitleWithCodeLink2 link="contract" />

Creates a contract object that wraps an ABI. Allows you to easily call
functions on the contract.

## Usage

``` javascript
tronWeb.contract(abi,contractAddress);
```

## Parameters
| Parameters | Description | Type |
|------------|-------------|------|
| abi |Optionally provide the ABI for a contract.| Array|
| address | Optionally provide the address for a contract. Hex or Base58 format | String |

## Returns

Object - The contract instance.

## Example

```ts
//example 1:Create the contract object through contract address and ABI
let instance = await tronWeb.contract([{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}],"contractAddress")

//example 2:First create an empty contract object, and then specify the contract address by at() function. If the abi is on the chain, at() function will load ABI automatically , else you need to load it manually 
let abi = [...] as const;
let instance = await tronWeb.contract(abi, "contractAddress");
```

If the contract ABI does not exist on the chain, Please invoke loadAbi
function to manually load the contract ABI. An example is as below:

```ts
//example 1
let instance =await tronWeb.contract([{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}],"contractAddress")
let res = await instance.name().call({_isConstant:true})

//example 2
let abi = [];
let instance = await tronWeb.contract(abi, "contractAddress");
instance.loadAbi([{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"}]);
let res = await instance.name().call({_isConstant:true})
```
