Introduction to TRC20 Tokens
TRC20 tokens are digital assets built on the TRON blockchain, offering fast transactions and low fees. This guide will walk you through the complete process of creating and deploying your custom TRC20 token.
Prerequisites
Before beginning, ensure you have:
- The TronLink wallet extension installed
- At least 100 TRX in your account for gas fees
- Basic familiarity with smart contracts

Step 1: Install TronLink Wallet
- Add the TronLink extension to your Chrome browser
- Create or import an account
- Fund your wallet with TRX (minimum 100 TRX recommended)
Step 2: Prepare Your TRC20 Smart Contract
Access the standard TRC20 contract template from the TRON Developer Hub repository. You'll need to modify these key parameters:
| Parameter | Description | Example Value |
|---|---|---|
| Token Name | Your token's full name | "MyToken" |
| Token Symbol | Trading symbol (3-5 characters) | "MTK" |
| Decimals | Divisibility (standard is 18) | 18 |
| Total Supply | Maximum token quantity | 1000000000 |
Step 3: Deploy Your Contract
Follow this deployment process:
- Navigate to Tronscan's contract compiler
- Connect your TronLink wallet
- Upload your modified Token.sol file
- Compile using version 0.5.10 of the Solidity compiler
- Select "Token" as your main contract during deployment
- Confirm the transaction through TronLink

Step 4: Register Your Token
After successful deployment:
- Visit Tronscan's token creation portal
- Select "TRC20" as your token type
Enter metadata matching your contract:
- Token name and symbol
- Contract address
- Official website/social links (optional)
- Complete the verification process
Step 5: Verify Your Contract
Enhance transparency by verifying your contract:
- Provide your contract address
- Specify compiler details (version 0.5.10)
- Upload your source code
- Complete the verification process
Best Practices for TRC20 Tokens
- Maintain adequate TRX reserves for transactions
- Double-check all contract parameters before deployment
- Consider implementing a token lock mechanism for team allocations
- Document your token's use case and economics
Frequently Asked Questions
What's the difference between TRC10 and TRC20 tokens?
TRC10 tokens are simpler to create but lack smart contract functionality, while TRC20 tokens offer full programmability and compatibility with decentralized applications.
How much does it cost to create a TRC20 token?
The base cost is approximately 100 TRX for deployment, plus additional gas fees for transactions during the creation process.
Can I update my token after deployment?
No, the core parameters (name, symbol, total supply) are immutable once deployed. You would need to create a new token contract for significant changes.
Is coding experience required to create a TRC20 token?
Basic coding knowledge helps, but you can modify the template contract with just text editing skills for simple implementations.
How do I distribute my tokens after creation?
You can send tokens directly from your deployment address or create a distribution contract for more complex allocation schemes.
What makes TRC20 tokens special compared to ERC20?
TRC20 tokens benefit from TRON's high throughput (2,000 TPS) and lower transaction fees compared to Ethereum's network.
