The world of blockchain and cryptocurrencies can be overwhelming, especially when you encounter technical terms like token standards, TRC-20, or TRC-721. Even seasoned crypto enthusiasts may find it challenging to clearly distinguish between them. But once you understand what token standards are and how they function, these concepts become much simpler.
This comprehensive guide dives into the core token standards on the TRON blockchain—TRC-10, TRC-20, and TRC-721—explaining their unique features, use cases, and why they matter in the broader ecosystem of decentralized applications and digital assets.
👉 Discover how token standards power the future of digital assets on high-performance blockchains.
What Is a Token Standard?
A token standard is a set of rules, functions, and conditions that define how a cryptocurrency token operates within a blockchain network. These standards ensure that tokens are interoperable, predictable, and compatible across wallets, exchanges, decentralized applications (dApps), and smart contracts.
On blockchains that support smart contracts—like TRON—token standards serve as blueprints for creating, issuing, and managing new tokens. They specify critical functionalities such as how tokens are transferred, how balances are recorded, and how user approvals are handled.
Without standardized protocols, every developer would create tokens differently, leading to fragmentation, security risks, and integration challenges. Standards bring consistency, security, and scalability to the ecosystem.
The TRON Blockchain: A Foundation for Innovation
TRON is a high-throughput, decentralized blockchain platform designed to support scalable dApps and a robust ecosystem of digital assets. One of its key strengths lies in its support for multiple token standards, enabling developers to launch different types of tokens based on specific needs—whether for utility, governance, or digital collectibles.
As of 2025, over 82,000 tokens have been issued on the TRON mainnet. Among these:
- Over 77,000 are based on the TRC-20 standard (≈93.68%)
- More than 3,600 follow the TRC-10 standard (≈4.42%)
- Around 1,500 utilize the TRC-721 standard (≈1.87%)
Together, these three standards account for more than 99% of all tokens on TRON, making them the most widely adopted frameworks on the network.
Let’s explore each one in detail.
TRC-10: Native Tokens on TRON
The TRC-10 standard is natively supported by the TRON blockchain and does not require the use of the TRON Virtual Machine (TVM). Instead, TRC-10 tokens are created directly on the blockchain through a simple transaction—no smart contract deployment needed.
Key Features of TRC-10
- Native issuance: Tokens are issued at the protocol level, making them faster and more efficient to create.
- Fixed supply: The total supply must be defined at creation and cannot be changed later.
- Single token per account: Each TRON account can issue only one TRC-10 token.
- Issuance cost: Requires a one-time fee of 1,024 TRX, which helps prevent spam.
Because TRC-10 tokens bypass smart contracts, they consume fewer resources and offer lower transaction fees—ideal for projects seeking simplicity and speed. However, their functionality is limited compared to smart contract-based tokens.
TRC-20: Smart Contract-Powered Utility Tokens
The TRC-20 standard is the most popular token framework on TRON, used for creating fungible tokens via smart contracts on the TRON Virtual Machine (TVM). It is fully compatible with Ethereum’s ERC-20 standard, allowing seamless migration and interoperability between the two ecosystems.
Why TRC-20 Dominates the TRON Ecosystem
- Flexibility: Developers can customize token behavior—minting schedules, burning mechanisms, pausing functions, etc.
- Interoperability: Wallets and exchanges can easily integrate TRC-20 tokens by following a standardized interface.
- Multiple tokens per account: Unlike TRC-10, users can deploy and manage numerous TRC-20 contracts from a single wallet.
- Ethereum compatibility: Projects from Ethereum can port their ERC-20 tokens to TRON with minimal code changes.
This standard powers major stablecoins like USD Coin (USDC) and Tether (USDT) on TRON, contributing to its status as one of the top blockchains for DeFi and payments.

TRC-721: The Standard for Non-Fungible Tokens (NFTs)
Introduced as TRON’s first NFT standard, TRC-721 enables the creation of unique, indivisible digital assets—each with a distinct identifier and ownership record. This standard is ideal for digital art, collectibles, gaming items, virtual real estate, and other one-of-a-kind assets.
Key Characteristics of TRC-721
- Uniqueness: Each token has a unique ID and cannot be exchanged on a one-to-one basis like fungible tokens.
- Ownership tracking: Built-in functions allow precise tracking of ownership and transfer history.
- ERC-721 compatibility: Smart contracts written for Ethereum’s NFT standard can be adapted for TRON with little effort.
- Royalty support: Creators can embed royalty mechanisms to earn a percentage on secondary sales.
With growing interest in digital ownership and metaverse economies, TRC-721 has become a cornerstone of TRON’s expanding NFT marketplace landscape.
Why Token Standards Matter for Interoperability
Tokens built using the same standard share consistent behavior and interfaces, ensuring smooth interactions across platforms. For example:
- A wallet supporting TRC-20 can automatically recognize and display any new TRC-20 token.
- Decentralized exchanges can list new tokens without custom coding if they follow known standards.
However, tokens from different standards (e.g., TRC-10 vs. TRC-20) often lack direct compatibility. To bridge this gap, the industry has developed solutions like:
- Blockchain bridges: Allow tokens to move across different chains while preserving value.
- Wrapped tokens: Represent assets from one chain on another (e.g., wrapping BTC as a TRC-20 token).
- Cross-chain protocols: Facilitate communication and asset transfer between heterogeneous networks.
These innovations enhance liquidity, accessibility, and user experience across the broader crypto ecosystem.
Frequently Asked Questions (FAQ)
Q: What’s the main difference between TRC-10 and TRC-20?
A: TRC-10 tokens are native to the TRON blockchain and don’t require smart contracts, making them faster and cheaper to issue. TRC-20 tokens are created via smart contracts on the TVM, offering greater flexibility and programmability but requiring more technical setup.
Q: Can I convert a TRC-10 token into a TRC-20 token?
A: Not directly. Since they operate under different architectures, converting requires creating a new TRC-20 contract and implementing a migration plan—often involving token swapping or wrapping mechanisms.
Q: Are TRC-721 NFTs compatible with Ethereum wallets?
A: Yes—due to ERC-721 compatibility, many multi-chain wallets (like TronLink or MathWallet) can display and manage both ERC-721 and TRC-721 NFTs seamlessly.
Q: How much does it cost to issue a TRC-20 token?
A: Unlike TRC-10’s fixed 1,024 TRX fee, TRC-20 deployment costs depend on contract complexity and network congestion. However, gas fees on TRON remain significantly lower than on Ethereum.
Q: Can one wallet hold all three types of tokens?
A: Yes—modern wallets like OKX Wallet and TronLink support TRC-10, TRC-20, and TRC-721 tokens in a single interface, providing unified access to diverse digital assets.
