# Class: BondToken

Client for interacting with the Bond Token (ERC20) contract

Provides an interface for interacting with ERC20 tokens used for bonding in self-attestations
and other platform functions. This client handles token operations like approvals and balance checks,
with a test-only minting function.

## Remarks

Token approvals are required before any operation that needs to transfer tokens
(self-attestation, endorsements, etc.)

### new BondTokenClient()

> **new BondTokenClient**(`publicClient`, `walletClient`, `contractAddress`): [`BondTokenClient`](./bond-token)

#### Parameters

##### publicClient

##### walletClient

##### contractAddress

`` `0x${string}` ``

#### Returns

[`BondTokenClient`](./bond-token)

## Methods

### mint()

> **mint**(`account`, `amount`): `Promise`\<`` `0x${string}` ``>

Mints new bond tokens to a specified account (only for testing)

#### Parameters

##### account

`` `0x${string}` ``

Address that will receive the minted tokens

##### amount

`bigint`

Amount of tokens to mint

#### Returns

`Promise`\<`` `0x${string}` ``>

Transaction hash

#### Remarks

This function is only available on test networks. In production/mainnet,
tokens must be acquired through proper channels (exchanges, transfers, etc).

### approve()

> **approve**(`spender`, `amount`): `Promise`\<`` `0x${string}` ``>

Approves an address to spend tokens on behalf of the caller

#### Parameters

##### spender

`` `0x${string}` ``

Address that will be approved to spend tokens

##### amount

`bigint`

Amount of tokens to approve

#### Returns

`Promise`\<`` `0x${string}` ``>

Transaction hash

#### Example

```typescript theme={null}
// Approve tokens for self-attestation
const bondAmount = parseEther('0.0001');
await sdk.bondToken.approve(attestationServiceAddress, bondAmount);
```

### balanceOf()

> **balanceOf**(`account`): `Promise`\<`bigint`>

Gets the balance of an account

#### Parameters

##### account

`` `0x${string}` ``

Address to check balance of

#### Returns

`Promise`\<`bigint`>

Balance of the account

#### Example

```typescript theme={null}
// Check account balance
const balance = await sdk.bondToken.balanceOf(userAddress);
```

### allowance()

> **allowance**(`owner`, `spender`): `Promise`\<`bigint`>

Gets the allowance of an account to spend another account's tokens

#### Parameters

##### owner

`` `0x${string}` ``

Address of the token owner

##### spender

`` `0x${string}` ``

Address of the token spender

#### Returns

`Promise`\<`bigint`>

Amount of tokens the spender is allowed to spend

#### Example

```typescript theme={null}
// Check if contract has enough allowance
const currentAllowance = await sdk.bondToken.allowance(userAddress, contractAddress);
if (currentAllowance < requiredAmount) {
  await sdk.bondToken.approve(contractAddress, requiredAmount);
}
```
