    What is TRC20

    TRC20 token is a technical standard based on the implementation of smart contracts. It is taken into use when a user uses the TRON network to issue a token. TRC20 token is a technical measure layered on the execution of smart contracts.

    Usually, when the TRON network uses smart contracts to issue a token, it is entirely harmonious with Ethereum’s ERC20. It requires a smart contract with a ton of addresses to create a TRC20 token. A TRC20 token can be traded with several exchanges in the market.

    It can be purchased from an ICO crowd sale or used in dApps as a payment gateway or building your own projects. TRC20 token cannot be obtained via API and have bandwidth charges for API transfers and deposits, as claimed by users.

    TRC20 tokens can be adopted for expediting conditional and quick transactions. The advanced bonus configuration system works on a first-come-first-serve basis. Besides, it has a more powerful energy level and maximum bandwidth capacity in comparison to the TRC10 token.

    What is TRC20 All About?

    TRC20 is a standard token based on the smart contracts’ execution when working with the TRON network to issue a token. All the TRC20 tokens follow a specific system that includes 6 essential items and 3 optional items.

    These specifications follow when users want to swap, transfer, share tokens, and be endorsed by digital wallets. The standard features of TRC20 tokens include:

    • Enables token swaps when using dApps.
    • The holder of the token can significantly use the data without any restrictions.
    • Each transaction executed on the platform can be monitored easily via the public ledger.
    • Payments are processed firmly via a decentralized peer-to-peer network.
    • Can be used on Tron wallets on multiple platforms such as Windows, Android, iOS, and macOS.
    • Has high capacity due to the speedy execution of transactions.
    • Entirely scalable and can assist a large number of users as the organization expands.
    • The reward allocation mechanism is reasonable due to a greater degree of decentralization providing a substantial intrinsic value.
    • Has a customizable interface with accessibility to smart contacts.
    • Investors can quickly learn the complexities of the token structure.
    • There is no firm protection delivered in case the investors list their tokens.
    • Uses famous storage systems like KhaosDB and levelD.
    • TRON’s in-built proof of stake consensus system can help to avoid the issue of counterfeit chains.

    Steps for Creating a TRC20 Token

    You will need to install the TRONLink wallet’s chrome plugin on browsers like Brave and Google Chrome, like by pressing the add to chrome button on the latter. After that, you will need to update the environment to the Shasta test net. You will have to create an account for building the tokens. Now you can follow the steps down below:

    • Set a token name and the symbol, and the number of supplies.
    • Click on the create wallet button. You need to have at least 10 TRX in your current account.
    • Ensure you have entered correct details, such as the token symbol, total supply for the contract code, and token name.
    • Implement the TRONScan tool for installing the TRC20 contract.
    • Compile the contract via uploading the contract code.
    • You have to click on the confirm button to implement the contract using TRONBox.
    • A TRONLink signature dialog box will appear, and you have to record the contract address as described.
    • Add all the tokens to the TRONLink. You can also access the homepage of the contract via TRONScan.
    • After submitting, the contract address, name, compiler version, and license, the contract will be successfully validated.
    • The information you enter must be equalized with the TRC20 contact.
    • A popup dialog box will appear and ask for the confirmation of token issuance.
    • You need to click on the confirm button and enter a signature via the TRONLink popup.
    • Afterward, all the tokens will be successfully recorded.
    • You have to register the token to TronScan.
    • Now, install the TRONWeb application for combining the token contract and Compile and Deploy your Token.

    The Right Process for Transferring your TRC20 Token

    Follow the steps mentioned down below to properly transferring your TRC20 token:

    • Employ TrustNote, which is a famous distributed ledger in the crypto market.
    • After installing it, switch the address of the genesis part from Maine to testnet.
    • Now you have to look for constant.js from the TrustNotke token record. Just wait for data synchronizing to inaugurate.
    • Generally, it takes around 15 minutes and also depends on the network speed.
    • After this process, a twinned wallet will be produced and saved as the file format of address.json in your TrustNote token record. Simply copy that address.
    • Insert it in the send to address input form. You can open the testnet explorer to check your account balance.
    • Now create _asset.js from the TrustNote toke record.
    • You will need to press click on the enter button from the place you applied for input.
    • Now open the testnet explorer and click the search option for submitting your Token ID.
    • You have to enter the number of units to be relocated to the target address.
    • Check the transferred token results by opening the testnet explorer and submitting the target address through the search button.
    • All the tokens will be relocated soon from your wallet.

    Now you will have to select Blockchain App Factory for TRC20 token development services. This will assure advanced functionalities in the smart contract and delivers robust security and loyalty that suits your company requirements, such as TRONStation, TRONStudio, TRONGrid, and TRONWeb for TRC20 token development.

You can also hire a shrewd developer team for getting abstruse knowledge, on-time delivery, complete transparency, and continuous 24×7 technical support.

    3 Optional Items

    1. Token Name

    string public constant name = “TRONEuropeRewardCoin”;

    2. Token acronym

    For instance, TERC is the acronym of TRONEeuropeRewardCoin. Both TRONEuropeRewardCoinand and TERc represent the same token, but TERC is considered to be simpler.

    string public constant symbol = “TERC”;

    3. Token Precision

    It is the minimum divisible unit. Precision means the minimum divisible unit is one. Precision 2 means the lowest token precision that has a divisible unit is 0.01. Generally, the maximum value of precision is 18.

    uint8 public constant decimals = 6;

    Necessary Items

    The code down below is an abbreviated TRC20 smart contract:

    contract TRC20 {function totalSupply() constant returns (uint theTotalSupply);function balanceOf(address _owner) constant returns (uint balance);function transfer(address _to, uint _value) returns (bool success);function transferFrom(address _from, address _to, uint _value) returns (bool success);function approve(address _spender, uint _value) returns (bool success);function allowance(address _owner, address _spender) constant returns (uint remaining);event Transfer(address indexed _from, address indexed _to, uint _value);event Approval(address indexed _owner, address indexed _spender, uint _value);}

    1. totalSupply()

    The totalSupply() function returns the total supply of the token value.

    contract MyTRCToken { uint256 _totalSupply = 1000000; function totalSupply() constant returns (uint256 theTotalSuppl { theTotalSupply = _totalSupply; return theTotalSupply; }}

    2. balanceOf()

    The balanceOf() function returns the token balance from a particular account.

    contract MyTRCToken { mapping(address => uint256) balances; address public owner; // Owner of this contract function balanceOf(address _owner) constant returns (uint256 balance) { return balances[_owner]; }}

    3. transfer()

    The transfer() function is used to send an amount of token from the smart contract to a particular address.

    contract MyTRCToken { mapping(address => uint256) balances; function transfer(address _to, uint256 _amount) returns (bool success) { if (balances[msg.sender] >= _amount && _amount > 0 && balances[_to] + _amount > balances[_to]) { balances[msg.sender] -= _amount; balances[_to] += _amount; Transfer(msg.sender, _to, _amount); // trigger event return true; } else { return false; } }}

    4. approve()

    The approve() function is used to authorize the third part, such as dApp smart contract. It helps to transfer tokens from the token owner’s specific account.

    contract MyTRCToken { mapping(address => mapping (address => uint256)) allowed; function approve(address _spender, uint256 _amount) returns (bool success) { allowed[msg.sender][_spender] = _amount;

    // msg.sender is the third party’s account Approval(msg.sender, _spender, _amount);

    // trigger event return true; } }

    5. transferFrom()

    The transferFrom() function enables a third-party to send a token from an owner account to a recipient account. Here, the owner account must be authorized to be considered as the third-party.

    Question: What is the difference between transfer() & transferFrom()?

    Answer: By utilizing transerFrom(), the third-party can immediately send tokens from your account to a receivers’ account.

    contract MyTRCToken { mapping(address => uint256) balances; function transferFrom(address _from, address _to, uint256 _amount) returns (bool success) { if (balances[_from] >= _amount && allowed[_from][msg.sender] >= _amount && _amount > 0 && balances[_to] + _amount > balances[_to]) { balances[_from] -= _amount; balances[_to] += _amount; Transfer(_from, _to, _amount); return true; } else { return false; } }}

    6. allowance()

    The allowance() function is used to inquire about the remaining amount token the third- party can send. It can approve the third-party to send a token from the owner’s account, then through transferFrom(), it transfers tokens to a recipient account.

    For example:

    Jack owns 1000 TRX. If he requires to allow the third-party contract, Lee, to control 1000 TRX from his account, then

    1. Call approve(Lee, 100) using Jack’s account.
    2. Contract Lee needs to transfer 10 TRX to other accounts from Jack. Call transfer from (Jack and other accounts, 10) using contract Lee’s account.
    3. Call allowance(Jack, Lee) to inquire about the remaining token that the contract Lee can transfer from Jack’s account.

    7. Event Functions

    event Transfer(address indexed _from, address indexed _to, uint256 _value)

    This is when the token is successfully sent, it has to activate the Transfer Event.

    event Approval(address indexed _owner, address indexed _spender, uint256 _value)

    When the approval() function is successful, it has to active an Approval event.

    A Brief Comparison Between TRC20 and TRC10 (TRC20 vs. TRC10)

    TRC20 is a technical standard used for smart contracts on the TRON blockchain for implementing tokens with the TRON Virtual Machine. It is entirely harmonious with ERC-20. On the other hand, TRC-10 is a technical token standard supported by the TRON blockchain platform.

    • Features

    TRC-20 has perfect interface customization, however, TRC-10 has no interface customization. In terms of accessibility by the smart contract, both TRC-10 and TRC-20 are applicable. TRC-10 is fully accessible by API, whereas TRC-20 has no API accessibility.

    • The token Structure learning curve

    The TRC-10 has an easy learning curve. On the other hand, TRC-20 has a medium learning curve for developers. This simply means that learning and getting started with TRC20 takes more time as compared to TRC10.

    • Cost

    TRC-10 has a 1000 times lower transaction fee than TRC20 with the use of API, not by the smart contract. On the other hand, TRC-20 has a 1000 times higher transaction fee than TRC10.

    • Transfer

    TRC-20 has higher energy and standardized Bandwidth points. Whereas TRC-10 can use API to send but costs bandwidth points. For the transfer in a smart contract, it costs both bandwidth points and energy.

    • Resources

    TRC20 has a higher amount of resources than TRC10, which has relatively fewer resources and a smaller community since it is new.

    Conclusion

    Remember, the cost to develop TRC20 tokens depends on several factors, including:

    • The complexity of the company’s requirement,
    • The current marketing value for TRON(TRX),
    • The operations have taken for preserving the bandwidth and entry consumption of the Tron Network, and
    • The features needed in the TRC20 token.

    Besides, you can also contact the top experience developer team with your project specifications to learn more. We also discussed how the TRC20 token creates a feasible ecosystem where developers can incorporate various functions immediately in a smart contract-enabled structure. In fact, the TRC20 corresponds to ERC20.

    It allows users to execute transactions entirely with a hassle-free approach. Besides, the distribution system works on a first-come-first-serve basis. We also learned that the TRC20 token is blessed with an increased energy level and bandwidth than the TRC10 token. It is enabling TRC-20 to deliver a power-packed performance.
