Getting Started
Section titled “Getting Started”What is TRON?
TRON is a public blockchain network launched in 2018. It uses Delegated Proof-of-Stake (DPoS) consensus and is designed for high-throughput, low-cost transactions. Its primary use cases include stablecoin transfers (particularly USDT), decentralized finance, and content distribution. The native token is TRX.
What is TRX?
TRX is TRON’s native currency. It is used to pay transaction fees when you lack sufficient staked resources, to stake in exchange for Energy and Bandwidth, to vote for Super Representatives, and as collateral in DeFi protocols. TRX is divisible to 6 decimal places — the smallest unit is called a SUN (1 TRX = 1,000,000 SUN).
Do I need TRX to receive tokens or activate my wallet?
Receiving TRX or tokens requires no prior balance — anyone can send to your address even if it holds zero. A TRON address is activated on its first receipt of TRX. For sending TRC-20 tokens (like USDT), you need either staked Energy or enough TRX to burn for fees. Sending plain TRX only requires Bandwidth, which every account receives 600 free points of per day.
How much is the TRON account activation fee exactly? 0.1 TRX or 1 TRX?
The actual network fee to activate a new account is 1 TRX, though you will typically see ~1.1 TRX deducted in practice if you do not have staked resources.
The cost is split into two components:
- Account Creation Fee (1 TRX): This is the official protocol fee (Parameter #7) burned by the network to register a new address on the blockchain.
- Bandwidth Consumption (~0.1 TRX): Since the activation transaction itself occupies data on the blockchain, the network burns an additional small amount of TRX to cover the Bandwidth cost if the sender lacks staked resources.
Why the confusion? Historically, the fee was 0.1 TRX. TRON Governance Proposal #67 (2021) increased this to 1 TRX to prevent account-creation spam. Additionally, some hardware wallets (like Ledger) may recommend a 0.1 TRX minimum deposit to “see” the account in their interface, but this is a software requirement and is separate from the on-chain activation fee.
Note on Smart Contract Activation: If you activate a new account by sending USDT (TRC-20) instead of TRX, the cost is significantly higher — typically between 13–15 TRX. This is because contract execution requires Energy in addition to the account creation fee.
Why is my TronLink showing "Account not activated"?
A TRON address does not exist on-chain until it receives its first inbound transaction. An unactivated address has no on-chain record. To activate it, have someone send any amount of TRX to your address (even 1 TRX). Some exchanges require activation before they will process a withdrawal — activate first by receiving a small amount from another wallet.
Is TRON legitimate? What is the story with Justin Sun and the SEC?
TRON is a live, functioning public blockchain that has operated continuously since 2018. It processes millions of transactions daily, carries the largest volume of USDT transfers of any network, and has a functioning DeFi ecosystem. The protocol itself — the software, the consensus mechanism, the smart contract system — is legitimate open-source infrastructure.
The controversy centres on its founder, Justin Sun. In March 2023, the U.S. Securities and Exchange Commission charged Justin Sun and related entities with alleged market manipulation and unregistered securities offerings. In March 2026, Sun and the SEC reached a settlement. The TRON DAO itself is a separate organisation from Justin Sun personally, and the blockchain continued operating without disruption throughout the legal process.
What this means practically: the network functions, your funds on TRON are controlled by your private keys (not any company), and the protocol is not going to be “shut down” by a lawsuit. The legal proceedings are part of the broader regulatory scrutiny that most major blockchain founders and projects are navigating globally.
Will TRON (TRX) ever reach $1?
Reaching the $1.00 milestone depends on TRON’s ability to scale its total market capitalization to match its massive network utility. Rather than focusing on short-term price fluctuations, the path to this level is driven by network scarcity and ecosystem dominance.
As the primary blockchain for global USDT volume, TRON generates consistent demand for TRX as the essential resource for transaction energy and bandwidth. Because the network burns TRX through transaction fees, sustained high activity creates deflationary pressure, reducing the total supply over time. While reaching $1.00 would require a significant increase in total market valuation, TRON’s position as a leading settlement layer and its growing count of hundreds of millions of wallet addresses provide the structural foundation for long-term growth.

Wallets & Security
Section titled “Wallets & Security”What are the most common TRON scams?
Fake customer support — No official TRON entity will DM you first. Anyone claiming to help you recover funds or asking for your seed phrase is a scammer.
Malicious token airdrops — Tokens can be sent to your wallet by anyone. Receiving unknown tokens is harmless; interacting with (approving or swapping) them can drain your wallet.
Phishing websites — Sites that mimic TronLink, JustLend, SunSwap, and other protocols to steal your seed phrase or trigger malicious approvals.
Unlimited approval exploits — DApps requesting unlimited token spending approvals. If that contract is later exploited, all approved funds can be drained.
Address poisoning — Attackers send tiny transactions from addresses that look nearly identical to yours. Always verify the full address, not just the first and last few characters, before copy-pasting from history.
What is a seed phrase and why does it matter?
A seed phrase (also called a mnemonic or recovery phrase) is a sequence of 12 or 24 words that encodes your wallet’s master private key. Anyone who has your seed phrase has complete control of every account derived from it. It cannot be changed. If lost alongside your device, your funds are permanently unrecoverable. Store it offline, in multiple physical locations, never digitally.
Can I recover my wallet without my seed phrase?
No. The seed phrase is the only way to restore a wallet on a new device. TRON is decentralized — there is no account recovery service and no authority that can override a lost key. The only exception is if you have the raw private key for a specific address, which lets you restore that individual address.
What does an "unlimited approval" mean and is it risky?
When you interact with a DeFi protocol, it asks you to “approve” it to spend a token on your behalf. An unlimited approval means the contract can spend any amount of that token from your wallet at any future time. If the contract is later exploited or is malicious, your entire approved token balance is at risk. Best practice: approve only the amount needed, or use TRONSCAN to revoke stale approvals.
What happens if I send TRX to the wrong address?
The transaction is final and irreversible. There is no undo, no chargeback, and no authority to reverse it. Always copy-paste addresses and verify the first and last several characters before confirming.
How do I verify a token contract is legitimate?
Look up the contract address on TRONSCAN (tronscan.org). Check: Is the source code verified and published? Does the contract address match what the official project website lists? Avoid tokens where the contract is unverified or newly deployed without history.
Should I use a hardware wallet with TRON?
Yes, for significant holdings. A hardware wallet (Ledger supports TRON) keeps your private key in a secure chip that never exposes it to your computer. Each transaction must be physically confirmed on the device.
Is TronLink safe to use?
TronLink is the standard TRON wallet and is widely used. Like all browser extensions, its security depends on your browser environment and the sites you visit. Keep it updated, only install from official sources, and never enter your seed phrase on any website.
Fees & Resources
Section titled “Fees & Resources”What is Bandwidth on TRON?
Bandwidth covers the byte-size cost of a transaction. Every transaction consumes Bandwidth proportional to its on-chain footprint in bytes. Each account receives 600 free Bandwidth points per day that regenerate continuously. Additional Bandwidth comes from staking TRX.
What is Energy on TRON?
Energy covers the computational cost of executing smart contract operations on the TVM. More complex contract calls consume more Energy. Energy is obtained exclusively by staking TRX — there is no free daily Energy allowance.
How do I get Energy?
Stake TRX via Stake 2.0 and select Energy as the resource type. Energy regenerates over approximately 24 hours after being consumed. You can also rent Energy from third-party providers on TRONSCAN if you only need it occasionally.
How much does a TRX transfer cost?
A standard TRX-to-TRX transfer consumes Bandwidth. With free daily or staked Bandwidth, it costs nothing. Without resources, TRON burns approximately 0.1–0.3 TRX to cover the cost. Every account receives 600 free points per day, enough for roughly 2 basic transfers.
How much does a USDT (TRC-20) transfer cost?
USDT transfers have two energy components. The base Energy is ~14,650 for an existing USDT holder, or ~29,650 for a recipient with zero USDT balance. On top of this, the Dynamic Energy Model applies a congestion penalty (up to 340%) based on how heavily the USDT contract is being used. The theoretical maximums are:
- ~64,460 Energy for an existing holder at full congestion (~6.4 TRX burned)
- ~130,460 Energy for a new account at full congestion (~13.0 TRX burned)
During low-congestion periods, costs can be as low as ~1.5 TRX. Actual cost depends on network conditions and recipient status.
Why does my USDT transfer say "insufficient energy" when I have TRX?
TRON’s energy system is separate from TRX balance. You need either staked Energy or enough TRX to burn. Without staking, expect to burn 1.5–13 TRX for a USDT transfer depending on congestion and recipient status. If your balance is lower than the required burn cost, the transaction fails.
How much TRX do I need to stake for USDT transfers?
At current staking yields (~9.2 Energy/TRX/day), you need to stake approximately 1,590 TRX to generate enough Energy (14,650) for a single daily USDT transfer to an existing holder. For new accounts (~29,650 Energy needed), stake approximately 3,200 TRX per daily transfer. Use the Energy Calculator for precise planning.
What happens if I run out of Energy mid-transaction?
TRON automatically burns TRX from your wallet to cover the deficit. The transaction still completes; you pay in TRX instead of staked resources. If you have no TRX and no Energy, the transaction fails with an “Out of Energy” error.
Can I rent Energy instead of staking?
Yes. Energy rental platforms (listed on TRONSCAN) allow you to pay a small TRX fee to receive a temporary Energy delegation. This is cost-effective for occasional users who do not want to lock TRX for 14 days.
What is the difference between Energy and Gas?
Gas on Ethereum must be purchased with ETH for every transaction. On TRON, Energy is pre-funded by staking TRX, making execution essentially free once sufficient resources are staked.
What is the Dynamic Energy Model (DEM)?
The Dynamic Energy Model (DEM) is a congestion-control mechanism on TRON designed to allocate network resources equitably. When a specific smart contract (like the USDT contract) consumes more than a certain threshold of the network’s Energy in a 24-hour period (currently 5 billion Energy), a penalty multiplier is applied to all transactions interacting with that contract.
This multiplier can increase the Energy cost of transactions by up to 340% (a 4.4x multiplier) during peak usage. The DEM ensures that heavily used contracts don’t monopolize network resources without paying a proportional cost.
Why do TRC-20 transfer fees vary between different tokens?
TRC-20 transfer fees fluctuate primarily due to three factors:
- Contract Complexity: Some tokens have more complex code (e.g., built-in taxes, custom logic) that inherently requires more Energy to execute than a simple standard transfer.
- Dynamic Energy Model (DEM) Penalties: High-traffic contracts like USDT often trigger the DEM congestion penalty, multiplying their base Energy cost by up to 4.4x. Low-traffic tokens usually don’t incur this penalty.
- Recipient Account Status: Transferring tokens to an address that doesn’t currently hold that specific token costs more Energy (an additional ~15,000 Energy) because the network must allocate new storage space to record that balance.
Staking & Voting
Section titled “Staking & Voting”What is staking on TRON?
Staking means locking (freezing) TRX to receive network resources (Energy/Bandwidth) and governance rights (TRON Power). Staking is the core of the TRON network economy.
What is Stake 2.0?
TRON’s current staking model. Key features: 14-day lock-up period, resource delegation to other addresses, persistent votes, and support for partial unstaking.
How long does it take to unstake TRX?
There is a 14-day waiting period after initiating an unstake in Stake 2.0. After 14 days, you must manually “withdraw” the funds to your available balance.
I unstaked TRX but it hasn't appeared in my available balance after 14 days. What do I do?
After the 14-day waiting period, you must manually “withdraw” the unstaked TRX. In TronLink, go to Stake → Unstake → Withdraw. Funds do not automatically return to your balance.
What is TRON Power?
Voting weight earned from staking: 1 TRX staked = 1 TRON Power. TP is used to vote for Super Representatives. When you unstake TRX, the corresponding TP is removed and any active votes are cancelled.
What is a Super Representative?
The 27 accounts receiving the most TRON Power votes in each 6-hour cycle. SRs produce blocks and receive rewards. The next 127 are SR Partners, who receive voting rewards but do not produce blocks.
What is the difference between an Epoch and a Maintenance Period?
While often used interchangeably, they represent different concepts: an Epoch is a duration of time, while a Maintenance Period is a governance event.
- Epoch (The Cycle): A 6-hour measurement (7,200 blocks) representing a full cycle of block production. It is the period during which SRs produce blocks and users accumulate rewards.
- Maintenance Period (The Event): A 6-second event (2 blocks) occurring at the end of each Epoch. It is an “administrative break” where the network recalculates the Super Representative set, applies approved governance parameters, and updates reward balances.
Think of the Epoch as the 6-hour “marathon” of production, and the Maintenance Period as the 6-second “sprint” of network accounting.
How do SR voting rewards work?
Most SRs distribute a portion of their income (block rewards) to their voters. Rewards must be claimed manually. To maximize returns, select SRs with high vote-sharing ratios (e.g., 90-100%).
What is the approximate annual staking yield?
Typical yields range from 3–5% APY on staked TRX, plus the economic value of the generated Energy/Bandwidth.
Can I delegate staked resources to another address?
Yes. You can stake TRX in your wallet and delegate the resulting Energy or Bandwidth to any other address. Your TRX stays in your wallet, while the recipient gets the resources.
DeFi & Ecosystem
Section titled “DeFi & Ecosystem”What is JustLend?
The leading decentralized lending protocol on TRON. Users supply assets (TRX, USDT, BTC, etc.) to earn interest or borrow against collateral. It is non-custodial and governed by JUST DAO.
What is SunSwap?
The primary decentralized exchange (DEX) on TRON. It uses Automated Market Maker (AMM) pools for trading. V3 supports concentrated liquidity for higher efficiency.
What is the SUN token?
The governance and incentive token of the SunSwap ecosystem. Used for liquidity mining rewards and protocol governance.
What is SunPump?
A fair-launch memecoin platform on TRON. Tokens launch without initial liquidity; once a market cap threshold is hit, they migrate to SunSwap with locked liquidity.
How do I trade memecoins on TRON?
Trading primarily happens on SunPump (new launches) and SunSwap. Many users also use specialized Telegram Trading Bots for faster execution and limit orders on TRON.
What is GasFree and how does it work?
A feature that allows USDT transfers without holding TRX for fees. The fee is instead deducted from the transferred USDT amount. Supported by TronLink and major TRON protocols.
What is the difference between TRC-20 USDT and ERC-20 USDT?
Both are 1:1 pegged to USD, but run on different chains. TRC-20 (TRON) is fast and cheap; ERC-20 (Ethereum) is slower and more expensive. They are not directly interchangeable on-chain.
How do I bridge assets to TRON from another chain?
Use a centralized exchange (easiest) or on-chain bridges like BitTorrent Bridge. Verify bridge domains carefully to avoid phishing.
Why did my swap fail with "Price impact too high"?
The size of your trade would move the pool price more than your slippage tolerance (usually 0.5–2%). Try splitting the trade or increasing slippage tolerance.
What is impermanent loss?
The relative loss liquidity providers face when the price of tokens in a pool diverges from their price at the time of deposit.
TRONSCAN & Tools
Section titled “TRONSCAN & Tools”What can I do on TRONSCAN?
TRONSCAN (tronscan.org) is the ultimate explorer. You can look up transactions, addresses, and contracts; check resources; revoke approvals; verify code; and monitor SR voting.
How do I check my Energy and Bandwidth balance on TRONSCAN?
Search for your address and open the Resources tab. This provides the most authoritative real-time view of your Energy and Bandwidth state.
How do I revoke a token approval on TRONSCAN?
Navigate to your address page and click the Approval tab. Click “Revoke” next to any contract and confirm in your wallet.
Why does TRONSCAN show a different TRX balance than my wallet?
Wallets often show “available” balance, while TRONSCAN shows “total” balance (including staked TRX). TRONSCAN is always the definitive source.
Can I view my NFTs on TRONSCAN?
Yes. TRONSCAN has an “NFTs” section for every address, supporting both TRC-721 and TRC-1155 standards.
Troubleshooting
Section titled “Troubleshooting”What does "REVERT" or "OUT OF ENERGY" mean on a failed transaction?
REVERT means the contract rejected the logic (e.g. slippage hit). OUT OF ENERGY means you ran out of computational resources. Both result in a failed transaction that still costs a small amount of resources.
My transaction shows "failed" but TRX was still deducted — why?
The network charges for the work done up to the point of failure. This covers the cost of on-chain data and CPU cycles used before the transaction reverted.
Why is my transaction not showing up?
TRON transactions are nearly instant (~3s). If it doesn’t appear on TRONSCAN, it was likely rejected before broadcast. Check your wallet balance and resource state.
Why did my bridge transaction not arrive?
Bridges can take from minutes to hours. Verify the source transaction on its explorer, then use the bridge’s own tracking tool. Contact the official bridge support if it exceeds the expected time.
What does "bandwidth limit exceeded" mean?
You’ve used up your free daily (600) and staked Bandwidth. Wait for it to regenerate or stake more TRX for Bandwidth.
What is TAPOS and why does it matter?
Transaction as Proof of Stake (TAPOS) ensures transactions reference a recent block. This prevents old transactions from being replayed on network forks.
Why does my token show a huge balance of an unknown token I didn't buy?
This is an airdrop scam. Scammers send fake tokens to trick you into interacting with a malicious contract. Do not sell or swap these tokens — ignore them.
Can I send USDT to a TRX address?
Yes. On TRON, your TRX and USDT (TRC-20) addresses are the exact same T-address.
Developers
Section titled “Developers”What is the TVM and how does it differ from the EVM?
Broadly compatible, but with key differences: TRON API returns millisecond timestamps; TVM handles SELFDESTRUCT differently; and address prefixes use 0x41.
How do I get Nile testnet TRX for development?
Use the official Nile faucet at nileex.io. Nile is the best environment for testing upcoming protocol features.
Can I use Ethers.js or Web3.js with TRON?
Not directly. Use tronweb (npm install tronweb), which is tailored for TRON’s address format and transaction structure.
What is TronBox and how does it compare to Hardhat?
TronBox is the TRON-native development framework (equivalent to Hardhat/Truffle). It handles migrations, deployments, and testing.
What should I know about Energy optimization in smart contracts?
Minimize storage writes (SSTORE), use view for off-chain reads, and avoid unbounded loops. Storage is the most expensive resource on the TVM.
How do I detect if a TRON address is a contract or an EOA?
Check if the bytecode field returned by the /wallet/getcontract API is non-empty.
How do I set up resource delegation for my users?
Use Stake 2.0’s delegateResource API to assign Energy from your staked balance to your users’ addresses.
What is the TIP process and how are TRON protocol changes made?
TRON Improvement Proposals (TIPs) are discussed on GitHub and voted on by Super Representatives to apply network-wide parameter changes.
What is the TRON gRPC API and when should I use it instead of the HTTP API?
TRON’s gRPC API (available at grpc.trongrid.io:50051) exposes the full protocol buffer interface. It is faster and more efficient than the HTTP API for high-throughput scenarios (exchange backends, node operators, bulk transaction submission). The Trident Java SDK is designed specifically for gRPC. Use HTTP for web applications and explorers; use gRPC for server-side backends requiring high throughput.
