General Tron Questions

What are TRC10 and TRC20 tokens?

Tron (TRX) is a blockchain platform for decentralized applications (Dapps).

Similar to other blockchain platforms like Ethereum, Tron allows users to create or issue tokens on its blockchain. These tokens can be used as a Dapp's currency or for whatever purpose token issuers can think of.

However, instead of ERC20 which is a popular type of Ethereum token, Tron has what are known as TRC10 and TRC20 tokens.

TRC10 vs. TRC20

Aside from easy token creation (TRC10) and native smart contract functionality (TRC20), there are a few other key notable differences between the two types of tokens:

  • TRC10 is accessible via API (application programming interface)
  • TRC10 has 1000 times lower transaction fees than TRC20 but has bandwidth costs for API transfers and deposits
  • TRC10 transfers and deposits into smart contracts cost bandwidth and energy

Note: bandwidth allows users to perform Tron transactions, and energy allows users to process Tron smart contracts. Instead of paying gas fees (small amounts of cryptocurrency, such as in Ethereum's network where gas = small amounts of ETH) to perform these tasks, users freeze or lock up TRX tokens in their wallet, which generates bandwidth and energy.

For more differences between TRC10 and TRC20, see Tron's website.

If you want to buy some TRX and take a jab at creating your own Tron-based token, Exodus gives you a safe and simple way to buy TRX with other blockchain assets!

What is Tron frozen balance?

The Tron network allows every user to send TRX from their wallet 20 times every day and not pay any network fees. 

Freezing some TRX allows you to gain more free transactions per day. Currently Exodus wallet does not support TRX freezing, however if you have used your Exodus Tron private keys in a different wallet that supports freezing, then you may now notice that Exodus allows you to see your frozen Tron balance.

Please note: If you have not used your Tron private key in a different wallet and frozen some Tron yourself there, then you will not see Advanced Options.

How do I see my frozen balance inside of Exodus?

If you know you have frozen some Tron in a different wallet using your Exodus TRX private key and want to check the balance in Exodus, all you need to do is go to your Tron wallet inside of Exodus, click the three dots in the top right corner and finally click on Advanced Options.

Here you will see Total balance, Frozen Balance, and Available Balance.

Please note: If you have not used your Tron private key in a different wallet and frozen some Tron yourself there, then you will not see Advanced Options.

How do I unfreeze my Tron that I froze in a different wallet?

Again, Exodus wallet does not support freezing Tron.

However, when you freeze your Tron (using a different wallet), it will be frozen for a minimum of 3 days. After 3 days, you will need to go to the wallet you originally froze the Tron in to unfreeze it.

Tron coin Swap Questions

I have Tron (old) what should I do?

Tron (TRX) migrated out of Ethereum and into its own mainnet blockchain. The swap was exclusively done on exchanges, and the deposit window for the transition closed on June 26th. Medium - Tron Foundation - Guide to independence

If you still have any of the old ERC20 TRX tokens in your Exodus Wallet, you will need a Binance account as they are the only exchange still allowing you to swap.

Guide to swap Tron (TRX) to Mainnet


First open up your Exodus wallet and find your Tron (OLD) wallet.

Log into your Binance account and go to Funds and then Balances.
Search for your Ethereum ( ETH) wallet and click  Deposit.
Binance will display an ETH Receive address for you to send Ether. It will warn you to only send ETH to this address.

Please note: It will warn you to only send ETH to this address. 99.9% of the time, sending an asset to an unspecified address results in a loss of funds, this is a very unique exception.

Copy the ETH address from Binance and paste it into the Send details in your Exodus Tron (OLD) wallet.
Select All so your entire TRX balance is added to the transaction. In this example, we're sending 150 TRX (OLD) tokens to Binance. When you are ready, hit Send.

Please note: Because this is an ERC20 token transaction, you will need some Ether (ETH) to pay for the transaction fees.

You will be able to confirm that Binance detected the TRX deposit on your Deposit History.
After 19 blockchain confirmations, Binance will credit your deposit with the same amount of the mainnet Tron (TRX) tokens in your Binance TRX Wallet.

Now you can send these Mainnet TRX tokens back to your Exodus wallet, just remember to send them to the mainnet address, which should start with "T".
