CoolWallet, a Taiwan-based self-custody hardware wallet provider, announced on February 4, 2026, the integration of TRON’s energy rental services, enabling users to drastically cut transaction costs on the TRON blockchain without staking large amounts of TRX.
TRON’s resource model uses “Energy” and “Bandwidth” for transactions instead of traditional gas fees—Energy powers smart contract interactions and TRC-20 token transfers (e.g., USDT on TRON), while Bandwidth covers basic operations. Insufficient Energy typically forces users to burn TRX to cover costs, which can spike during congestion.
The new feature, powered by Tronify Energy Rental integration, lets CoolWallet users rent Energy directly via the wallet’s mobile app interface before executing transactions. This avoids burning TRX outright, often slashing fees significantly—reports indicate potential savings up to 33.9% compared to direct burning when resources are low. Users gain flexibility by paying rental costs in either TRX or USDT on TRON, ensuring predictable and lower expenses for frequent transfers, DeFi activities, or stablecoin movements.
The update applies across CoolWallet’s hardware devices (paired with the companion app), preserving full self-custody: private keys remain offline on the hardware, and users retain complete control over funds. No staking lockups are required for rentals, lowering barriers for everyday users.
CoolWallet positions the enhancement as a user-experience boost for TRON enthusiasts, particularly amid high USDT volumes on the network (TRON dominates stablecoin transfers). By streamlining resource management, it reduces friction in high-throughput scenarios without compromising security.
Industry observers see this as part of a trend among wallet providers to embed native blockchain optimizations—beyond basic send/receive—to compete on usability and cost efficiency. The move could drive more retail activity on TRON by making transactions cheaper and more accessible, especially for DeFi and cross-chain stablecoin use.
As blockchain fees remain a pain point, tools like energy rental gain momentum as alternatives to rigid models. CoolWallet’s adoption underscores rising demand for consumer-friendly, cost-saving features in hardware wallets.
