πͺWhat Are TRC20 Tokens?
TRC20 tokens are smart contract-based digital assets that operate on the TRON blockchain. They follow the TRC20 standard, which defines a set of rules that tokens must follow to be compatible with TRON wallets and exchanges. This standard is similar to ERC20 on Ethereum but optimized for TRON's high-speed, low-cost network.
TRC20 tokens include some of the most widely used cryptocurrencies in the world:
- USDT TRC20 β The most popular stablecoin on TRON
- USDC TRC20 β Another major stablecoin
- BTT β BitTorrent Token
- JST β JustStable
- SUN β SUN Token
- NFT tokens β TRC721 standard (similar to TRC20 for NFTs)
All TRC20 tokens are sent to the same TRON wallet address. You don't need a separate address for each token. If someone has your TRON address, they can send you any TRC20 token.
βAdding TRC20 Tokens to Your Wallet
Most TRON wallets automatically display TRX but may not show all TRC20 tokens by default. Here's how to add them:
-
1
Open your wallet
Open TronLink, Trust Wallet, TokenPocket, or any TRON wallet app.
-
2
Find the token management option
Look for a toggle icon (βοΈ), "Add Token," or "Manage Tokens" button in your wallet interface.
-
3
Search for the token
Type the token name (e.g., "USDT") in the search bar. Select the TRC20 version (not ERC20 or BEP20).
-
4
Add manually if not found
If the token doesn't appear, select "Add Custom Token" and enter the contract address, symbol, and decimals.
-
5
Confirm and save
Once added, the token will appear in your wallet. You can now send, receive, and track its balance.
The official USDT TRC20 contract address is TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t. Always verify this on TronScan or the official Tether website before adding.
πCommon TRC20 Token Contract Addresses
| Token | Contract Address | Decimals |
|---|---|---|
| USDT | TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t | 6 |
| USDC | TEkxiTehnzSmSe2XqrBj4w32RUN966rdz8 | 6 |
| BTT | TAFjULxiVgT4qWk6UZwjqwZXTSaGaqnVp4 | 18 |
| JST | TCFLL5dx5ZJdKnWuesXxi1VPwjLVmWZZy9 | 18 |
| SUN | TSSMHYeV2uE9qYH95DqyoCuNCzEL1NvU3S | 18 |
| WIN | TLa2f6VPqDgRE67v1736s7bJ8Ray5wYjU7 | 6 |
Scammers create fake tokens with similar names. Always verify contract addresses on TronScan or the official token issuer's website before adding. One wrong address can result in permanent loss of funds.
ποΈHiding Tokens
As you interact with more dApps, your wallet may accumulate many tokens β some useful, some not. Here's how to clean up your wallet view:
- Why hide tokens? Too many tokens can clutter your wallet and make it hard to find what you're looking for. Some tokens may be spam or dust tokens sent by scammers.
- How to hide: In most TRON wallets, go to the token management section, find the token you want to hide, and toggle it off or select "Hide."
- Token still appears? If a token still appears after hiding, it may have a balance. Some wallets automatically show tokens with a positive balance.
- Beware of dust tokens: Scammers send tiny amounts of unknown tokens (dust) to many addresses. Never interact with or swap these tokens β they may be part of a phishing or approval scam.
If you receive an unknown token out of nowhere, do not interact with it. Don't try to sell or swap it. It's likely a scam token designed to trick you into approving a malicious contract. Simply hide it and ignore.
πUnderstanding Token Approvals
When you interact with a dApp (like a decentralized exchange or lending platform), you often need to grant token approval β permission for the dApp's smart contract to spend your tokens on your behalf.
This is necessary for:
- Trading/Swapping: When you swap USDT for another token on SunSwap or another DEX.
- Lending/Borrowing: When you deposit tokens into a lending protocol.
- Staking: When you stake tokens in a yield farming or staking contract.
- Liquidity Pools: When you add liquidity to a pool.
If you grant approval to a malicious dApp, the contract can spend your tokens without your further consent. This is why you should always revoke approvals you no longer need and only interact with trusted dApps.
πRevoking Token Approvals
Revoking token approvals is an important security practice. Here's how to do it:
-
1
Go to TronScan
Visit tronscan.org and enter your wallet address in the search bar.
-
2
Navigate to Approvals
Look for the "Contract" tab or "Approvals" section on your address page.
-
3
Review active approvals
You'll see a list of dApps and the tokens they have permission to spend, along with the approval amount.
-
4
Revoke unwanted approvals
Click the "Revoke" button next to any approval you no longer want to keep. This removes the dApp's permission to spend your tokens.
-
5
Confirm the transaction
Revoking an approval is a transaction that requires a small fee (Energy). Confirm it in your wallet.
You should revoke token approvals regularly β at least once a month, or anytime you stop using a particular dApp. This reduces your attack surface and keeps your wallet secure.
πTracking Token Balances
Here are the best ways to track your TRC20 token balances:
- In your wallet: The simplest way β open TronLink, Trust Wallet, or your preferred wallet and view your balances.
- TronScan: Enter your wallet address on TronScan to see a complete list of all tokens you hold, including ones not displayed in your wallet.
- Portfolio trackers: Use tools like DeBank, Zapper, or CoinGecko Portfolio to track multiple wallets and see your total portfolio value.
- Token price: Remember that TRC20 tokens have different values. USDT and USDC are stablecoins (pegged to $1), while other tokens like BTT, JST, and SUN fluctuate with the market.
For a comprehensive view of all your TRON assets across multiple wallets, use DeBank or Zapper. They support TRON and show your total portfolio value in one dashboard.
π‘οΈToken Security Best Practices
- Always verify contract addresses: Before adding a token, verify its contract address on TronScan or the official token website.
- Revoke unused approvals: Regularly revoke token approvals for dApps you no longer use.
- Don't interact with unknown tokens: If you receive a token you don't recognize, don't try to swap or sell it β it could be a scam.
- Use a hardware wallet: For large holdings of valuable tokens like USDT TRC20, use a hardware wallet (Ledger or SafePal).
- Be cautious with dApps: Only interact with well-known, audited dApps. Check the dApp's reputation and security history before granting approvals.
- Check approval amounts: When granting approvals, some wallets allow you to set a spending limit instead of granting unlimited approval.
Never share your seed phrase with anyone. Whether it's for TRX or any TRC20 token, your seed phrase is the key to all your assets. Protect it at all costs.
