TRC-20 tokens are a technical standard used for creating and managing fungible tokens on the TRON blockchain. They enable the implementation of smart contracts to issue digital assets that are interoperable across the TRON ecosystem. While their design is inspired by Ethereum’s ERC-20 standard, TRC-20 tokens operate exclusively on the TRON network unless bridged to other blockchains.
Key Features of TRC-20 Tokens
TRC-20 tokens are integral to the TRON ecosystem. Here are some of their defining characteristics:
- They are fungible, meaning each token is identical and interchangeable.
- They rely on the TRON Virtual Machine (TVM) for execution.
- Transactions involving TRC-20 tokens require fees paid in TRX, TRON’s native cryptocurrency.
- They can represent various assets, including stablecoins, utility tokens, and governance tokens.
Daily transaction volumes for TRC-20 tokens often exceed $20 billion, largely driven by widespread use of TRC-20 based USDT.
How TRC-20 Tokens Work
The TRC-20 standard specifies a set of rules that all tokens on the TRON blockchain must follow. These rules ensure consistency and interoperability between different tokens and decentralized applications (dApps).
Core Functions
Every TRC-20 token includes these essential functions:
- Transferring tokens between wallets.
- Checking the balance of a specific wallet.
- Approving third parties to spend tokens on a user’s behalf.
- Retrieving the total supply of the token.
These functions allow developers to create dApps that seamlessly interact with various tokens.
TRON Blockchain: A Brief Overview
Launched in 2018, the TRON blockchain was designed to support high-throughput decentralized applications. It uses a Delegated Proof-of-Stake (DPoS) consensus mechanism, which enables fast transaction processing and low fees.
Key features of the TRON network include:
- High scalability, handling up to 2,000 transactions per second.
- Low transaction costs, often less than $0.01.
- Robust support for smart contracts and dApps.
Comparing TRC-20 with Other Token Standards
TRC-20 vs. ERC-20
Both standards serve similar purposes but operate on different blockchains:
- ERC-20 is used on Ethereum and relies on the Ethereum Virtual Machine (EVM).
- TRC-20 is native to TRON and uses the TRON Virtual Machine (TVM).
While both are widely used, TRC-20 transactions are generally faster and cheaper due to TRON’s network architecture.
Other TRON Token Standards
TRON supports multiple token standards, each serving unique purposes:
- TRC-10: A simpler standard that doesn’t require smart contracts. It has lower fees but fewer features.
- TRC-721: Used for non-fungible tokens (NFTs) on TRON.
- TRC-1155: A multi-token standard that supports both fungible and non-fungible assets in a single contract.
Creating a TRC-20 Token
Developing a TRC-20 token involves writing a smart contract in Solidity, the same programming language used for Ethereum. Here’s a step-by-step overview:
Step 1: Define Token Parameters
Specify the token’s properties, including:
- Name and symbol.
- Total supply.
- Decimal places.
Step 2: Implement Core Functions
Code the essential transfer, balance, and approval functions.
Step 3: Add Custom Features
Depending on the token’s purpose, you might include:
- Minting and burning mechanisms.
- Tax or fee structures.
- Integration with DeFi protocols.
Step 4: Deploy the Contract
Deploy the contract to the TRON blockchain, paying a fee in TRX. The cost varies based on contract complexity but is generally affordable.

Use Cases for TRC-20 Tokens
TRC-20 tokens are versatile and serve numerous applications:
Stablecoins
TRC-20 USDT is one of the most widely used stablecoins globally, offering fast and cheap transactions.
Utility Tokens
Many dApps on TRON issue utility tokens for accessing platform features.
Governance Tokens
Some projects use TRC-20 tokens to enable community voting and decision-making.
Wallets Supporting TRC-20 Tokens
To store and manage TRC-20 tokens, you need a compatible wallet. Popular options include:
TronLink
The official wallet for the TRON ecosystem, available as a browser extension and mobile app. It supports all TRON-based assets and dApps.
Trust Wallet
A multi-chain mobile wallet that supports TRON, TRC-20 tokens, and NFTs.
Atomic Wallet
A desktop and mobile wallet offering support for TRON and numerous other blockchains.
MetaMask and TRON
MetaMask does not natively support TRON or TRC-20 tokens. However, bridged versions of TRON assets on Ethereum-compatible networks can be stored in MetaMask.
Advantages of TRC-20 Tokens
- Low Fees: Transactions cost a fraction of a cent.
- High Speed: Blocks are produced every 3 seconds, enabling quick confirmations.
- Ecosystem Support: Tight integration with TRON dApps and services.
Frequently Asked Questions
What is the difference between TRC-20 and ERC-20?
TRC-20 tokens are native to the TRON blockchain, while ERC-20 tokens are used on Ethereum. TRC-20 transactions are typically faster and cheaper.
Can I store TRC-20 tokens on MetaMask?
Not directly. MetaMask does not support the TRON network. However, you can use bridges to move TRC-20 tokens to Ethereum-compatible networks and then store them in MetaMask.
How much does it cost to create a TRC-20 token?
Deployment costs vary but are generally around 100 TRX, making it affordable for most developers.
Are TRC-20 tokens secure?
Yes, provided the smart contract is audited and properly coded. Always use reputable wallets and practice good security hygiene.
What is TRC-20 USDT?
TRC-20 USDT is a version of Tether’s stablecoin issued on the TRON blockchain. It offers faster and cheaper transactions compared to other versions.
Can TRC-20 tokens be bridged to other blockchains?
Yes, cross-chain bridges allow TRC-20 tokens to be moved to other networks like Ethereum or BNB Chain.
Conclusion
TRC-20 tokens are a fundamental component of the TRON ecosystem, enabling the creation of diverse digital assets with low fees and high efficiency. Whether you’re a developer looking to launch a new token or an investor exploring TRON-based projects, understanding TRC-20 is essential.
Always conduct thorough research and prioritize security when interacting with cryptocurrencies. Use non-custodial wallets for storing your assets and ensure you understand the risks involved.
