# Create Custom SPL Tokens

Effortlessly deploy new SPL tokens with customized parameters using the TokenDeploymentManager class. This utility simplifies token creation for any project on the Solana blockchain.

**Code Breakdown**

**1. Determine Rent Exemption**

Calculate the minimum balance required for rent exemption to initialize the token account:

Copy

```
lamports = await connection.get_minimum_balance_for_rent_exemption(MINT_LEN)  
```

**2. Mint Keypair Generation**

A new keypair is generated to serve as the token's mint address:

Copy

```
mint = Keypair()  
logger.info(f"Generated mint address: {mint.pubkey()}")  
```

**3. Create Account for Token Mint**

An account is created with the calculated lamports for rent exemption and linked to the token program:

Copy

```
create_account_ix = create_account(  
    CreateAccountParams(  
        from_pubkey=agent.wallet_address,  
        to_pubkey=mint.pubkey(),  
        lamports=lamports,  
        space=MINT_LEN,  
        program_id=TOKEN_PROGRAM_ID,  
    )  
)  
```

**4. Initialize the Token Mint**

The mint is initialized with the specified decimals and authorities:

Copy

```
initialize_mint_ix = initialize_mint(  
    program_id=TOKEN_PROGRAM_ID,  
    mint=mint.pubkey(),  
    decimals=decimals,  
    mint_authority=Pubkey.from_string(agent.wallet_address),  
    freeze_authority=Pubkey.from_string(agent.wallet_address),  
)  
```

**5. Submit and Confirm the Transaction**

Both instructions are added to a transaction, signed, and submitted to the blockchain:

Copy

```
transaction = Transaction()  
transaction.add(create_account_ix, initialize_mint_ix)  

tx_signature = await agent.connection.send_transaction(  
    transaction, agent.wallet, mint, opts={"preflight_commitment": Confirmed}  
)  
```

**6. Error Handling**

If an error occurs during the process, it is logged and raised:

Copy

```
except Exception as e:  
    logger.error(f"Token deployment failed: {str(e)}")  
    raise Exception(f"Token deployment failed: {str(e)}")  
```

***

**Key Features**

1. **Customizable Parameters**
   * Define the number of decimals to suit the token's utility (default: 9).
2. **Efficient Resource Management**
   * Automatically calculates the required lamports for rent exemption.
3. **Seamless Integration**
   * Combines account creation and mint initialization into a single transaction.
4. **Error Logging**
   * Comprehensive logs ensure smooth debugging and transparency.
5. **Simplified Outputs**
   * Returns the new token's mint address and transaction signature.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kaze-ai.gitbook.io/kaze-ai/token-operations/create-custom-spl-tokens.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
