# address <TitleWithCodeLink2 link="address" />

Object that allows you to convert between hex / base58 and privatekey representations of a TRON address.

**Note**:
If you wish to convert generic data to hexadecimal strings, please use the function `TronWeb.toHex`.

## 1. TronWeb.address.toHex

Convert Base58 format address to Hex format address.

**Usage**

```javascript
TronWeb.address.toHex('base58 format address');
```

**Parameters**

string - Base58 format address

**Returns**

string - TRON Hex format address

**Example**

```javascript
TronWeb.address.toHex('TNPeeaaFB7K9cmo4uQpcU32zGK8G1NYqeL');
// output-start
'418840E6C55B9ADA326D211D818C34A994AECED808'
// output-end
```

## 2. TronWeb.address.fromHex

Convert Hex format address to Base58 format address.

**Usage**

```javascript
TronWeb.address.fromHex('hex format address');
```

**Parameters**

string - Hex format address

**Returns**

string - TRON Base58 format address

**Example**

```javascript
TronWeb.address.fromHex('418840E6C55B9ADA326D211D818C34A994AECED808');
// output-start
'TNPeeaaFB7K9cmo4uQpcU32zGK8G1NYqeL'
// output-end
```

## 3. TronWeb.address.fromPrivateKey

Derive its corresponding address based on the provided private key.

**Usage**

```javascript
TronWeb.address.fromPrivateKey(privateKey, strict);
```

**Parameters**

| Parameter | Description | Type |
| --------- | ----------- | ---- |
| privateKey | The private key. **Since 6.4.0** an optional leading `0x` prefix is accepted and stripped, so the key works with or without it. | string |
| strict | Optional, defaults to `false`. Forwarded to the internal hex parser; when `true`, an odd-length hex string is left-padded with a leading `0`. A well-formed 64-character key is unaffected. | boolean |

**Returns**

string - Base58 format address. Returns `false` only when the private key is invalid.

**Example**

```javascript
TronWeb.address.fromPrivateKey('AD71****7509');
// output-start
'TNPeeaaFB7K9cmo4uQpcU32zGK8G1NYqeL'
// output-end
// Since 6.4.0 a leading `0x` prefix is accepted and yields the same address
TronWeb.address.fromPrivateKey('0xAD71****7509');
// output-start
'TNPeeaaFB7K9cmo4uQpcU32zGK8G1NYqeL'
// output-end
```

## 4. TronWeb.address.toChecksumAddress

Convert a unchecksumed address to checksumed address.

**Usage**

```javascript
TronWeb.address.toChecksumAddress('417e5f4552091a69125d5dfcb7b8c2659029395bdf');
// output-start
'417E5F4552091A69125d5DfCb7b8C2659029395Bdf'
// output-end
```

**Parameters**

string - the unchecksumed address

**Returns**

string - the checksumed address

## 5. TronWeb.address.isChecksumAddress

Check if the input hex string is a checksumed address.

**Usage**

```javascript
TronWeb.address.isChecksumAddress('417e5f4552091a69125d5dfcb7b8c2659029395bdf');
// output-start
false
// output-end
TronWeb.address.isChecksumAddress('417E5F4552091A69125d5DfCb7b8C2659029395Bdf');
// output-start
true
// output-end
```

**Parameters**

string - the hex address

**Returns**

boolean - if it's checksumed address
