The Ethereum blockchain was the first to introduce smart contracts, launching in 2015 and experiencing explosive growth during the 2020 DeFi summer. However, Ethereum’s scalability limitations soon became evident—network congestion led to transaction delays and sharp spikes in gas fees during peak usage. These bottlenecks paved the way for competing blockchains offering faster speeds and lower costs.
In May 2018, the TRON mainnet launched, introducing the TRC-20 token standard. Designed with Ethereum as a blueprint, TRON features the TRON Virtual Machine (TVM), which executes smart contracts using the same programming language—Solidity—as Ethereum’s EVM. This compatibility enables seamless migration of decentralized applications (dApps) from Ethereum to TRON, lowering the technical barrier for developers.

But why would developers choose to migrate?
- Higher throughput: TRON processes transactions faster than Ethereum, crucial for scaling dApps.
- Lower operational costs: Complex smart contracts require more computational power, which on Ethereum translates into high fees. On TRON, minimal transaction fees allow developers greater flexibility in coding advanced functionalities without burdening end users.
Key Functions of TRC-20 Smart Contracts
TRC-20 smart contracts define the core behavior of tokens on the TRON blockchain, including transferability, issuance, circulation, and transaction mechanics. All transaction fees are paid in TRON’s native cryptocurrency, TRX.
Core Capabilities Include:
- Token Creation: Any user can issue custom digital assets on the TRON network.
- Token Burning: Enables programmed destruction of circulating tokens under specific conditions.
- Freezing Tokens: Halts all operations related to a particular smart contract.
- Ownership Control: Allows issuers to set permissions for interacting with the contract post-deployment. For greater decentralization, creators can renounce ownership and disable future modifications after launch.
These features empower entrepreneurs and developers to launch tokens for diverse use cases—from utility tokens and governance mechanisms to reward systems and NFT platforms.
TRC-20 vs. ERC-20 vs. BEP-20: How Do They Compare?
The ERC-20 standard served as the foundation for both TRC-20 (TRON) and BEP-20 (BNB Chain). While all three enable fungible token creation within their ecosystems, they differ significantly in performance, decentralization, and adoption.
Despite similar functionalities, key distinctions arise from underlying blockchain architecture:
- Transaction Speed: TRON and BNB Chain average 3 seconds per transaction, far outpacing Ethereum’s 13 seconds.
- Fees: TRON boasts the lowest average fee at just $0.14**, compared to Ethereum’s **$12 and BNB Chain’s $0.20.
- Daily Transactions: TRON leads with 7 million daily transactions, surpassing Ethereum’s 1 million and BNB Chain’s 4 million.
- Developer Ecosystem: Ethereum hosts 229 dApps with over $100K in value locked (per DappRadar), while TRON has only 10, highlighting its smaller developer presence.
Another major differentiator is decentralization. Ethereum has over 960,000 active validators, ensuring robust network security. In contrast, TRON relies on just 27 validators, raising concerns about centralization.
However, TRON’s popularity surged in 2019 with the launch of USDT (Tether) on its network. Today, over 50% of all circulating USDT tokens operate via the TRC-20 standard, according to DefiLlama. This widespread adoption makes TRC-20 a preferred choice for fast, low-cost stablecoin transfers.

Advantages of TRC-20 Tokens
- ✅ Supports decentralized applications (dApps)
- ✅ Enables easy creation of new digital assets
- ✅ Offers greater coding flexibility for developers
- ✅ High transaction speed (average 3 seconds)
- ✅ Extremely low fees (~$0.14 per transaction)
- ✅ Supports free transactions through energy/stake mechanisms
TRON allows users to perform fee-free transactions by staking TRX to gain “energy” or “bandwidth,” making it ideal for microtransactions and high-frequency trading applications.
Disadvantages of TRC-20 Tokens
- ❌ High degree of centralization (only 27 validators)
- ❌ Limited number of active dApps compared to Ethereum and BNB Chain
- ❌ Regulatory scrutiny: In March 2023, the U.S. SEC sued TRON founder Justin Sun and three affiliated companies for unregistered securities offerings
While TRC-20 offers technical advantages, its reliance on a small set of validators and ongoing legal challenges pose long-term risks for investors and developers.
Top 5 TRC-20 Tokens
- Tether (USDT) – The most widely used stablecoin on TRON, facilitating fast and cheap transfers.
- BitTorrent (BTT) – A token powering decentralized file-sharing and content distribution.
- JUST Network (JST) – Used for governance and collateral within TRON’s DeFi ecosystem.
- USDD (USDD) – A decentralized algorithmic stablecoin pegged to the U.S. dollar.
- APENFT (NFT) – Supports digital art and NFT projects on blockchain networks.
These tokens represent a mix of stablecoins, utility tokens, and DeFi instruments driving activity on the TRON network.

Frequently Asked Questions (FAQ)
What is the TRC-20 token standard?
TRC-20 is a technical standard used for implementing fungible tokens on the TRON blockchain. It defines rules for token transfers, approvals, and balances, similar to ERC-20 on Ethereum.
Is TRC-20 safe to use?
Yes, but with caveats. While the technology is secure, the centralized nature of TRON’s consensus mechanism introduces potential risks compared to more decentralized networks like Ethereum.
Why is USDT so popular on TRC-20?
Due to low fees and fast confirmation times, TRC-20 has become the go-to network for transferring USDT. Over half of all USDT流通 occurs on this chain.
Can I convert TRC-20 tokens to ERC-20?
Yes, through cross-chain bridges or exchanges that support both networks. Always verify withdrawal networks to avoid fund loss.
Are there free transactions on TRON?
Yes. By staking TRX, users can earn bandwidth and energy, allowing them to send TRC-20 tokens without paying fees.
How do I receive TRC-20 tokens safely?
Always confirm that both sender and receiver use the TRC-20 network. Sending USDT via ERC-20 to a TRC-20 address (or vice versa) may result in permanent loss unless recovered through customer support.
