What is TRC20


One of the major conundrums that newcomers in the world of token development are faced with consists of choosing the appropriate blockchain network for your particular needs. There are 3 popular options for creating tokens to choose from Ethereum, Binance Smart Chain, and TRON Blockchain.

Each of these blockchains comes with its own token standard, which is essentially a standardized set of rules governing the use of tokens on that blockchain.

While the subject of today’s article is specifically what is TRC20 standard of the TRON network, we will also compare all other relevant standards (along with their corresponding blockchain networks), so that you know what to expect when investing your hard-earned crypto in one of these platforms. Choosing the optimal token issuance standard is essential, so let’s get right down to business.

The Rise of TRON Network

What is TRC20 exactly? In order to answer this question, we should first briefly return to 2014. Eight years ago, the Ethereum network reigned supreme as the undisputed platform for developing USDT tokens. Ethereum smart contracts are used to create ERC20 tokens.

However, many users were dissatisfied with the high cost of transaction fees and the amount of time it took for blocks to be verified. One such user was Justin Sun, a then promising business executive (now the CEO of BitTorrent), who had decided to create his own blockchain network, one that would eliminate Ethereum’s shortcomings since the transaction fee on Ethereum gets only higher. Thus, the TRON blockchain was born.

In 2018, Sun exchanged the ERC 20 token standard (a leftover from TRON’s early days, when the platform’s architecture was still extremely similar to Ethereum’s) for the newly-created TRC-20 token standard. The effects were tremendous and immediately visible: those users who migrated from the Ethereum blockchain to Sun’s platform experienced five times shorter verification speeds, the transfer fee had been reduced, while also having to pay much lower gas fees (almost two times lower, in fact). Of course, they never looked back in Ethereum’s direction; it was obvious who had been the winner in the TRC-20 vs ERC 20 duel.

TRC-20 Basics

After an informative and entertaining lesson in history, let’s ask again: what is TRC20? Basically, it is a required standard that anyone interested in using (transferring, swapping, sharing) tokens on the TRON network must oblige with. TRON is a public blockchain, meaning that anyone can produce and issue their own TRON tokens, of course, as long as they comply with the standard rules.

Have in mind that there are six necessary items that must be implemented in order to comply with the TRC-20 token standard, along with three optional items. We will only list the items; if you’re interested in the underlying code, you can find it included in the TRON network developers’ guide for using the TRC-20.

The six required items include: totalSupply(), balanceOf(), transfer(), approve(), transferFrom(), allowance(); while the optional items are: Token Name, Token Abbreviation, Token Precision.

TRC20 vs. ERC20

Even though these two standards are compatible, before creating a crypto token for your business, you should learn the differences between these token standards. Some of the most distinct technical differences when it comes to ERC20 vs. TRC20 crypto tokens are listed below:

Blockchain networks: These tokens are created on different blockchains. The Ethereum network is used for ERC USDT (issued by Tether) and TRON is used for TRC USDT (issued on the TRON network).

Transfer speed: ERC tokens take up to 5 to 10 minutes, and TRC tokens transfer in a few seconds to a few minutes.

Fees: The average fee is around 30 USDT for ERC tokens and starts at 2 USDT for TRC tokens.

Security: Security measures are significantly higher in ERC tokens than in TRC crypto tokens.

Transactions per second: ERC tokens can process 20 transactions per second. However, TRC-based tokens are capable of processing around 2000 transactions per second.

TRC-20 vs. BEP-20

As we said in our previous ERC20 vs TRC20 match, the TRC-20 standard is undoubtedly superior in terms of speed and cost, but what about Binance’s BEP-20 (which is a standard for Binance’s Smart Chain platform)? Well, this is a duel whose winner will be much harder to announce, as the situation is complicated. First, though, it will be illuminating to take a look at some of the important similarities between the TRC-20 and BEP-20 standards.

The Three Competitors

Binance was founded shortly after TRON blockchain, arising from a very similar dissatisfaction with the low quality of Ethereum’s services. It is interesting that, due to both TRC-20 and BEP-20 having evolved out of the outdated ERC-20 standard (in fact, all three standards are based on the same programming language, named Solidity), Binance and TRON tokens and smart contracts are mostly compatible with Ethereum blockchain – tokens created on one network can be used on all three of them. However, the key difference, which sets apart the competitors, lies in the underlying consensus mechanism.

To put it simply, the network’s consensus mechanism ensures the legitimacy of transactions by synchronizing all network nodes. It is precisely the optimization of the network’s consensus mechanism(s) that allowed TRON and Binance to overcome the Ethereum blockchain. Namely, while ERC-20 uses the PoW (Proof of Work) consensus algorithm, TRC-20 and BEP-20 users enjoy the customized, improved, and updated mechanisms, initially based on the old PoW, but much superior. TRON’s DPoS (Delegated Proof of Stake) and Binance’s PoSA (Proof of Staked Authority) are far more efficient ways (and with lower fees) of ensuring the legitimacy of transactions.

Why is this so? We’ll spare you the less interesting technical details. Instead, we’ll discuss other advantages these blockchains have over the Ethereum network.

Power Consumption

Power Consumption

Namely, with DPoS and PoSA, there’s practically no mining involved (and with DPoS, there’s no mining involved at all)! DPoS can achieve this because the new blocks on the blockchain are validated according to the number of coins that are staked. Of course, no mining means less power consumption, which, in turn, leads to substantially less ecological damage. Therefore, avoiding ERC-20 will not only be good for you and your wallet, but you’ll also have the gratitude of Mother Earth, which is clearly a win-win situation.

Who Won?

Let us now return to the original question of this section of the article – which standard is superior, TRC-20 or BEP-20? Basically, it depends on how you look at things. The generally more secure standard is TRC-20. Binance, however, has a pretty low level of security so that’s one of its biggest drawbacks. Both standards offer the same results in terms of block verification speed (3 seconds per block). On the other hand, the transaction fees you’ll need to pay when using BEP-20 will likely be lower, somewhere between 0.4$ and 15$, while with TRC-20 tokens, you can expect to spend more than 15$ for each transaction. Can better security compensate for the higher fees? We’ll let you answer this one.

Wallets & Exchanges

If you have definitely decided that TRC-20 tokens are the right choice for all of your advanced token production needs, it is now time to procure a TRC20 wallet and/or find a suitable crypto exchange. Of course, we recommend storing your cryptocurrency in a secure wallet whenever you aren’t actively trading or converting the USDT tokens because even the safest exchanges can be hacked. Also, keep in mind that not all wallets that come with support for TRON transactions will also support the TRC20 USDT tokens, so be sure to check whether that is the case before buying your first USDT.

We’ll conclude this section of the article with two lists. The first one is a list of our recommended TRC20 wallets (which definitely support the TRC20 USDT tokens), and the other one is a selection of the best exchanges dealing in TRC20. Among them, you should be able to find and simply choose a TRC20 wallet and a TRC20 exchange that’ll suit you.
