In the rapidly evolving landscape of blockchain technology, implementing robust security features has transformed from a secondary consideration to a fundamental requirement. When developing tokens on the Sui network, incorporating a pausable mechanism provides project owners with a critical emergency control system. Sui tokens equipped with pausable functionality offer an advanced security layer: the ability to temporarily halt all token transfers network-wide with a single transaction, giving projects the emergency response capabilities and compliance infrastructure essential in today's regulatory environment.
Why Pausable Tokens Are Essential on Sui
Consider this scenario: you've successfully launched your token on the Sui blockchain, but suddenly discover unusual trading patterns or a potential security vulnerability affecting multiple users simultaneously. With standard tokens, your response options would be limited and time-consuming. However, with a pausable Sui token implementation, you gain immediate crisis management capabilities to protect your entire community by temporarily freezing all token transfers while you investigate and resolve the situation.
Pausable tokens on Sui are particularly valuable for:
- Projects requiring rapid response mechanisms to security incidents.
- Protocols needing to meet evolving regulatory compliance standards.
- DAOs and communities implementing comprehensive governance safeguards.
- Platforms seeking to protect their entire user base during critical updates.
In this guide, we'll walk you through creating your own token with a pausable feature on the Sui blockchain using 20lab's Sui token generator - a user-friendly tool that eliminates complex coding requirements. You'll discover how to configure your token parameters, implement pausable functionality, and effectively manage your token's pause controls through an intuitive dashboard. Whether you're a blockchain developer, project founder, or new to the Sui ecosystem, this tutorial will demonstrate how to deploy a token with emergency controls that can safeguard your entire project ecosystem.
How to Create Your Sui Token with Pausable Feature
We'll be using the 20lab.app platform to create our Sui token with pausable functionality. This intuitive Sui token generator simplifies the token creation process, making it accessible to everyone regardless of technical background.
Step 1: Choose Token Type and Connect Wallet
First, visit 20lab.app, navigate to the generator page and click on "Create Sui Token".
Next, connect your Sui wallet (such as Suiet wallet, Sui wallet or Stashed) to the platform. Upon successful connection, you'll see your wallet address displayed in the top right corner.
Make sure you're connected to the Sui Mainnet (or Sui Testnet/Devnet if you're experimenting). While 20lab supports multiple blockchains, for this guide, we'll focus specifically on creating a token on the Sui network with pausable functionality.
Step 2: Add General Token Information
When creating your token on the Sui blockchain, carefully configure the initial parameters that will define your token's characteristics.
First, set your token's name and symbol. The token name is the full name, while the symbol serves as a shorter identifier. Unlike many other blockchains, Sui offers the flexibility to change both the name and symbol later if you have the treasury cap and metadata authority.
Your module name is a unique identifier that appears at the end of your Sui token address (coin type). It must follow specific syntax rules:
- Must start with a lowercase letter.
- Can only contain lowercase letters, numbers and underscores (_).
- Cannot be changed after deployment.
Choose how divisible your token will be by setting the decimal places (0-9). For best compatibility within the Sui ecosystem:
- Most common values are 6 or 9 decimal places.
- Higher decimal places will limit your maximum initial supply.
- This setting is permanent and cannot be changed after deployment.
The initial supply determines how many tokens are created at launch. When setting this value, consider:
- The maximum initial supply depends on the number of decimal places you choose.
- Lower decimal places allow for higher initial supply value.
- This will be your fixed supply unless you also enable the mintable feature.
When creating your Sui token, you'll need to specify two important wallet addresses:
- The supply recipient address, which will receive all tokens created during initial deployment (defaults to your connected wallet)
- The treasury cap address, which holds administrative control over your token's restricted functions (also defaults to your connected wallet)
Step 3: Enabling the Pausable Feature
The pausable feature is one of the most powerful emergency control mechanisms you can integrate into your Sui token. This functionality gives you the ability to halt all token transfers network-wide with a single transaction in case of emergencies or security incidents.
In the "Optional" features section of the generator, you'll find the "Freezable" option which must be enabled to access the pausable functionality. The pausable mechanism is implemented as an extension of the freezable feature, allowing deny cap holder to effectively blacklist everyone with just one transaction.
When enabled, this feature creates three important components:
- A deny list connection which will store all frozen addresses.
- A deny cap that will have authority to add and remove addresses on this list.
- The pausable functionality that extends the deny cap's capabilities to include global pausing.
The key difference between individual freezing and pausing is that after pausing your token, addresses previously frozen on an individual basis will be preserved, and after unpausing your token, those addresses will still remain frozen. This provides an additional layer of control and security.
Step 4: Review and Deploy
Before deploying your token with the pausable feature on the Sui network, take the time to carefully review all configured settings on the "Summary" page. This final check ensures your token will function as intended once deployed.
On this page you'll see all your chosen configurations:
- Token name and symbol,
- Module name,
- Initial supply and decimals,
- Supply recipient address,
- Treasury cap address,
- Freezable & pausable feature settings.
Click the "Validate" button to perform a technical review of your token configuration. This ensures all parameters meet Sui requirements and identifies any potential issues prior to deployment.
If validation is successful, click "Deploy" to create your token on the Sui network. Your connected wallet will prompt you to authorize the transaction and cover the necessary gas fees. After confirming the transaction, your token will be deployed on the Sui blockchain with all specified parameters and pausable capabilities!
Managing Your Pausable Sui Token
After deploying your token on the Sui network, 20lab's dashboard provides a comprehensive interface to monitor and manage your token, including the pausable feature.
The dashboard displays essential token information, including your token's coin type (address), current supply, token name, symbol, and decimal places. You can also review other configured parameters such as the module name and treasury cap holder.
The "General (Sui)" section of the 20lab dashboard provides essential functions for managing your Sui token. Here you can merge your coin objects into a single one, check the balance of specific addresses, transfer and burn tokens.
A critical capability accessible through the dashboard for tokens with pausable functionality is the global pause control system, managed by the deny cap holder. The "Pausable" section provides an intuitive interface to activate the global pause when necessary.
To activate the global pause function, follow these steps:
- Navigate to the "Pausable" section of your token dashboard.
- Look for the "Pause" button.
- Click "Pause" to initiate the process.
Your connected wallet will prompt you to approve the transaction and cover the gas fees. Once the transaction is confirmed on the Sui network, all token transfers will be halted network-wide, providing immediate protection during security incidents or critical updates.
Similarly, to deactivate the global pause when the situation is resolved:
- Return to the "Pausable" section.
- Click "Unpause" to initiate the process.
- Approve the transaction through your connected wallet.
Remember that after unpausing, any addresses that were individually frozen before the global pause will remain frozen, maintaining your granular control over specific addresses while restoring functionality to the wider network.
Conclusion
Creating a token with pausable functionality on the Sui network provides essential emergency controls for your project. The ability to temporarily halt all token transfers with a single transaction gives you the means to protect your entire community during critical situations while maintaining granular control through individual address freezing.
