When people ask for USDT payment, do they mean ERC-20 or TRC-20? Exploring Token Standards in Cryptocurrency Transactions

TRC-20 or ERC-20: Exploring Token Standards in Cryptocurrency Transactions | The Enterprise World


Understanding USDT

Tether (USDT) has become a staple in the cryptocurrency markets over the past few years. As a stablecoin pegged to the US dollar, it provides a way for traders to have price stability amidst the volatility typically found in crypto assets. With a market capitalization over $70 billion, USDT is now the third-largest cryptocurrency behind only Bitcoin and Ethereum.

A key reason for USDT’s popularity is its availability on different blockchains. While originally an asset on the Bitcoin-based Omni protocol, USDT now also exists as tokens on blockchains like Ethereum (ERC-20) and Tron (TRC-20). This interoperability has increased its accessibility and utility in the crypto economy. However, it also means users need to pay attention to the specific token standard when making USDT transactions. The choice between TRC20 vs ERC20 has become an important consideration for USDT payments.

TRC-20 or ERC-20: The Basics

TRC-20 or ERC-20 are technical standards that define how tokens are issued and interact on their respective blockchain networks.

ERC-20 is the dominant standard for representing assets and tokens on the Ethereum blockchain. Popular stablecoins like USDC and DAI along with governance tokens like UNI all conform to ERC-20. The standard’s ubiquity has made ERC-20 interoperable with almost all Ethereum-based software.

TRC-20 is a similar technical standard but for the Tron blockchain network. It achieves the same goals as ERC-20 but within Tron’s ecosystem. The TRC-20 standard has gained traction thanks to Tron’s focus on high throughput and low transaction fees. Major stablecoins like USDT and USDC have Tron-based TRC-20 tokens to complement their ERC-20 variants.

Advantages and Disadvantages of ERC-20

As the most established token ecosystem, ERC-20 USDT enjoys wide compatibility with cryptocurrency apps and services. For example, all self-custody Ethereum wallets like MetaMask support ERC-20 by default. Most centralized exchanges that support Tether also provide ERC-20 deposits and withdrawals.

This ubiquity provides ERC-20 USDT owners with flexibility in terms of asset management. Tokens can be moved between various DeFi protocols across decentralized exchanges. Integration with layer 2 networks like Optimism can also help reduce transaction costs.

However, ERC-20 continues to be plagued by high network congestion on Ethereum which causes increased gas fees and slower settlement times. During peak usage periods, transacting USDT via ERC-20 can become exorbitantly expensive. While ecosystem growth could alleviate some bottlenecks, Ethereum continues to have scalability issues impacting ERC-20 transactions.

Advantages and Disadvantages of TRC-20

TRC-20 USDT transactions occur on the Tron blockchain, known for its high transaction throughput and low fees. Trades that take minutes on Ethereum and cost several dollars settle in seconds for cents on Tron. This speed and cost advantage make TRC-20 suited for microtransactions and crypto-to-crypto trades.

Additionally, given founder Justin Sun’s aggressiveness, the Tron ecosystem has seen increased USDT adoption for DeFi and NFT use cases. TRC-20 or ERC-20 provides access to Sun-affiliated projects which source liquidity from his Tether allocations. These ecosystems are attempting to rival Ethereum but continue to have far lower adoption presently.

The biggest tradeoff with TRC-20 USDT is less seamless interoperability between non-Tron-centric apps and platforms. For example, markets that solely support ERC-20 cannot directly interface with TRC-20 USDT without conversions through centralized exchanges. This fragmentation can introduce additional steps for users looking to interact across ecosystems.

Popular Use Cases and Preferences

In Asia, early Tron adoption has made TRC-20 networks popular for transacting USDT pairs. Sun’s connections have allowed geo-targeted partnerships in the region to boost liquidity. Gambling and gaming dApps built on Tron chains also rely heavily on TRC-20 USDT for settlement flows.

Meanwhile, in Western markets, USDT’s first mover advantage on Ethereum has entrenched ERC-20 as the dominant standard. Trading desks and OTC providers closely adhere to ERC-20 to service investor expectations. Decentralized exchanges like Uniswap only have ERC-20 market pairs without swapping through intermediaries first.

These geographic differences are noteworthy for USDT market participants. Sources and destinations of fund flows might prescribe optimal token standards to minimize friction and conversion costs. However, as blockchain bridges and atomic swaps proliferate, this blockchain bifurcation may converge over time.

Navigating USDT Payments: What to Look For

With the same USDT asset living on multiple networks, users should pay close attention to the specific token implementation required.

When receiving requests for USDT payments, carefully examine which standard the counterparty specifies. If the instructions only mention USDT without a token prefix, clarify if they prefer TRC-20 or ERC-20 settlement.

Exchanges will designate deposit addresses specifically for TRC-20 or ERC-20 USDT when initiating transfers. Sending to mismatched standards could result in lost funds. Always verify the destination supports the blockchain network from your wallet.

Meanwhile, for DeFi protocols and dApps, check the documentation to determine proper USDT formats. Teams usually highlight Ethereum compatibility while Tron requires manual token wrapping. These technical specifics reduce errors and unlock usage across USDT’s fragmented blockchain presence.

As USDT usage grows across chains, vigilance on token standards when transacting minimizes complexity. While confusing at first, practical checks to confirm network support reduce mistakes and platform inconsistencies.

Future Trends and Developments

The ongoing success of USDT across different blockchains suggests potential expansion to additional smart contract networks seeking stablecoin liquidity. Competitor blockchains like Solana, Polkadot, and Cardano may add TRC-20 equivalents as interest and adoption follow USDT.

Layer 2 scaling solutions for Ethereum like Arbitrum may also introduce standards that mirror USDT’s cross-chain reach. However, their benefits remain narrowly focused on improving Ethereum transaction throughput rather than facilitating external blockchain ecosystems.

In the long term, the importance of token distinctions may fade as decentralized blockchain bridges and swaps create more seamless cross-network functionality. Still, USDT’s multi-standard approach will likely form an important building block enabling asset mobility across layer 1s and layer 2s.


The stratospheric rise of Tether showcases the growing stablecoin influence across cryptocurrency markets. Its availability as both TRC-20 or ERC-20 tokens has increased USDT accessibility but also introduced complexities in managing blockchain divergence.

Understanding the user base, transaction speed, cost profile, and compatibility tradeoffs between Ethereum and Tron clarifies appropriate USDT standards for different situations. Checking these distinctions on interfaces helps avoid functionality issues or lost transfers due to incorrect formats.

While fragmented blockchain ecosystems pose short-term challenges, USDT’s cross-chain expansion also represents a blueprint for advancing truly borderless digital value exchange. Paying attention to technical specifications when making USDT payments paves the way for this frictionless future.
