TRON (TRX) is a prominent blockchain platform known for its high throughput and scalability. It supports a variety of decentralized applications and smart contracts. This guide provides essential information for developers and users managing TRON wallets and transactions, covering key concepts, operations, and best practices.
Understanding TRON Networks and Resources
TRON operates on two primary networks: the mainnet for production use and a testnet for development and testing.
- Production Network: The live blockchain environment where real TRX and tokens are transacted.
- Testnet: A simulated network for testing applications without using real assets.
For development purposes, the testnet faucet provides test TRX tokens. These are essential for experimenting with wallet operations and smart contracts without financial risk.
Block explorers like Tronscan allow users to inspect transactions, addresses, and network activity. They are invaluable tools for verifying transaction status and exploring blockchain data.
Creating and Funding a TRON Wallet
Generating a TRON wallet is straightforward using either BitGoJS or the platform API. The process involves creating a new wallet instance with a unique label and a secure passphrase.
When using BitGoJS, the generated wallet provides a root address. This address must be funded with at least 100 TRX to cover the initial wallet creation cost. Additionally, maintaining a minimum balance of 0.1 TRX is crucial to keep the account active. Failure to do so will result in the account being deactivated, preventing it from interacting with the blockchain.

Generating Multiple Receive Addresses
BitGo supports the creation of multiple receive addresses within a single TRX wallet. This feature enhances privacy and organization by allowing users to segregate incoming transactions.
Each new address can be assigned a custom label, making it easier to track different sources of funds or specific transactions.
Managing TRX and Token Transactions
Sending TRX and TRC-20 tokens involves using the .sendMany() method. However, it's important to note that native TRX transactions only support a single recipient per transaction.
Transaction types must be specified accurately. For token transfers, use the 'TokenTransfer' type to ensure proper processing on the blockchain.
Understanding TRON Balances and Units
The native asset on the TRON blockchain is Tronix (TRX). Its smallest unit is the sun, where 1 TRX equals 1,000,000 sun. Balances are typically represented in string format to handle large numbers precisely.
Wallets can hold both native TRX and various TRC-20 tokens. BitGoJS provides methods to retrieve comprehensive balance information, including detailed token data.
TRON Fee Structure: Bandwidth and Energy
TRON utilizes a unique resource model for transaction fees, based on bandwidth and energy instead of a simple gas system.
- Bandwidth: Measures the size of transaction data stored on the blockchain. Each account receives 600 free bandwidth points daily. When this is exhausted, TRX is burned to cover additional bandwidth costs.
- Energy: Represents computational resources required for smart contract execution. Energy must be obtained by staking TRX. If insufficient energy is available, TRX is burned to cover the deficit.
Because fee calculation involves multiple variables and failed transactions still burn TRX, BitGo uses a maximum fee approach to ensure transaction success.
Current Fee Estimates
- TRX transfers: Approximately 2.1 TRX
- USDT token transactions: Approximately 35.83 TRX
- USDC token transactions: Approximately 17.02 TRX
- Wallet initialization: 100 TRX
Consolidating TRX and TRON Tokens
Consolidation involves moving funds from multiple receive addresses to the root address. This process helps manage funds more efficiently and reduces clutter.
For optimal results, consolidate tokens before TRX. This approach minimizes dust left on addresses and ensures sufficient TRX remains for future token consolidation fees. Note that addresses must have more than 1 TRX to be eligible for TRX consolidation.

Managing the Gas Tank for Automated Operations
TRON wallets can utilize a gas tank feature to automatically cover token consolidation fees. This system calculates the required TRX for consolidation and funds receive addresses accordingly when token deposits occur.
The estimated gas for a token consolidation transaction is 36 TRX, though actual costs may be lower. Receive addresses need sufficient TRX balance to cover these fees for each unique token they hold.
Gas Tank Funding Scenarios
- Address with 0 TRX receiving USDC: Funded with 36 TRX
- Address with 20 TRX receiving USDC: Funded with 16 TRX
- Address with 0 TRX receiving both USDC and USDT: Funded with 72 TRX
Maintaining adequate gas tank balance is essential for smooth operations. BitGo recommends keeping a minimum balance calculated as: average consolidations per cycle × 1.5 × 36 TRX.
Frequently Asked Questions
What is the minimum TRX balance required to keep a TRON account active?
TRON accounts must maintain a minimum balance of 0.1 TRX. If the balance drops below this threshold, the account becomes deactivated and cannot read data from the blockchain or perform transactions.
How does the gas tank feature work for token consolidation?
The gas tank automatically funds receive addresses with TRX when token deposits occur. It calculates the amount needed for future token consolidation (approximately 36 TRX per token) and sends the difference between the current balance and the required amount.
What happens if I consolidate TRX before tokens?
If you consolidate TRX first, the system will only move excess TRX beyond what's needed for potential token consolidation. This means some TRX will remain on the address to cover future token consolidation fees, potentially leaving funds fragmented across multiple addresses.
How can I obtain test TRX for development purposes?
Test TRX can be acquired from the TRON testnet faucet. This is essential for testing wallet operations, smart contracts, and transaction processing without using real assets or spending actual TRX.
What's the difference between bandwidth and energy in TRON's fee model?
Bandwidth measures transaction data storage requirements, while energy represents computational resources for smart contract execution. Both resources have free allowances, but when exceeded, TRX is burned to cover additional costs.
Why does wallet creation require 100 TRX?
The 100 TRX wallet creation cost covers the resources required to establish the account on the TRON blockchain. This includes the computational work and storage space needed to maintain the account state within the network.
