CoolWallet has added TRON’s energy leasing system to its hardware wallet, allowing users to lease energy from the grid instead of burning TRX for each transaction. This translates to up to 34% lower fees, preserving self-custody and generating higher returns.
Under TRON’s resource model, each transaction consumes energy, which users historically obtained by burning TRX. This mechanism entailed a direct cost for the end user, as each transaction reduced their token balance. Over time, this scheme became particularly inconvenient for those who make frequent or high-volume transactions.
CoolWallet’s integration introduces a different approach by channeling energy purchases through third-party providers. These providers acquire energy in bulk within the TRON ecosystem and then lease it to end users. Thanks to this bulk purchasing, the cost per unit of energy is lower than that of individual TRX burns, which explains the savings reported by the platform.
According to CoolWallet, this structure allows for a reduction in fees of up to 33.9%. Furthermore, the model offers greater flexibility, as rental fees can be paid in either TRX or USDT on TRON. At the same time, it decreases the need to burn TRX, allowing users to retain a larger portion of their tokens.
How energy leasing works and what users get
CoolBitX CEO Michael Ou characterized the move as support for the networks users rely on, saying, “It reflects our commitment to supporting the blockchain networks our users depend on most, while ensuring they retain security and full control over their assets.” A spokesperson for the TRON DAO community, Sam Elfarra, called the integration “an important step in making TRON’s infrastructure more accessible to users who prioritize security and self-custody.”
Another point to consider is the strong performance of TRON stablecoins throughout 2025, with transactions reaching nearly $8 billion, and high expectations for this year due to lower fees.
For product teams and compliance officers, the update changes operating cost profiles, as DeFi wallets and interfaces that integrate energy leasing can offer lower transaction costs while retaining custody responsibilities and associated KYC/AML considerations.
Adoption and cost outcomes measured in the weeks following the February 4–5, 2026 launch will indicate whether energy leasing materially alters fee dynamics for retail users and active DeFi participants. Product managers should track on-chain fee metrics, user retention of TRX balances, and any counterparty or custody considerations related to outsourced energy provisioning.
