+How to Buy TRON Energy Instantly (Save TRC20 Fees) 
+The "fresh wallet" surcharge exists because creating a new TRC20 token entry in the recipient's account uses extra contract storage. As of April 2026, Tron hosts roughly $86 billion of USDT — close to half the total Tether supply and the largest single-chain USDT footprint by a wide margin. For a deeper look at the issuer and the broader USDT footprint, see the Tether USDT 2026 guide.​ Tron itself is a delegated-proof-of-stake (DPoS) blockchain that produces a block every three seconds — the Tron blockchain guide covers the consensus model in depth.

+If your wallet’s TRX balance is above 0.8 TRX, even when Energy is paid with USDT, the system may still consume a small amount of TRX during the transaction to cover insufficient Bandwidth costs. It cannot be retained, reused for future transactions, or accumulated in the account. Any remaining Energy after the transaction is completed, or any Energy that is not used within the validity period, will automatically expire. The Energy Rental fee varies depending on the transaction’s resource requirements. Currently, Energy Rental supports standard TRC-20 token transfer transactions only and does not apply to other transaction types. If Energy is insufficient and Energy Rental is not enabled, TRX will be burned as the transaction fee.
+Why rent TRON Energy instead of burning TRX? 
+For example, when sending ERC-20 tokens on Ethereum, users must pay on-chain transaction fees in ETH. With this integration, CoolWallet users no longer need to manually manage complex resource configurations when sending TRC-20 transactions. As a result, when sending TRX or TRC-20 tokens, users often end up paying higher transaction fees without realizing it. However, many users are not familiar with TRON’s resource mechanism, such as Energy and Bandwidth. Executing transactions consumes these resources, similar to how gas fees are required for transactions on other blockchains. Energy and Bandwidth are system resources on the TRON blockchai

The "Hold Energy" function automatically maintains the set energy leve
