TRON Proposal 106 voting begins, changing SELFDESTRUCT rules, contract deletion, and energy costs for improved TVM compatibility.
TRON has started voting for Proposal No. 106, which introduces changes to the SELFDESTRUCT opcode.
The update affects contract deletion and transaction energy costs. Developers and network participants are advised to review the proposal carefully.
These changes aim to improve compatibility between TRON Virtual Machine (TVM) and Ethereum.
Contract Deletion Rules and Transaction Handling
According to the proposal, a contract will only be deleted if SELFDESTRUCT runs in the same transaction as creation.
Otherwise, the contract stays on the blockchain, while assets still transfer. This change prevents unexpected removal of contracts after they are deployed.
Developers are advised to adjust contract logic and test applications on test networks.
A TRON developer said, “Contracts remain traceable while assets move, which aligns TRON closer to Ethereum practices.”
By keeping contracts visible, the network improves transparency and reliability.
Moreover, historical contract data will remain accessible, allowing participants to verify transaction records.
The update helps maintain accurate logs for auditing and monitoring. It ensures that contracts continue to exist even after assets are moved.
This adjustment may affect projects that rely on immediate contract deletion.
Therefore, teams need to review how contracts handle asset transfers. The proposal encourages more structured management of contract lifecycles.
Energy Cost of SELFDESTRUCT Will Increase to 5,000
Proposal 106 also updates the energy cost of executing SELFDESTRUCT. Currently, the cost is zero, but if approved, it will rise to 5,000 energy units.
This change reflects the resources required to process such transactions.
The TRON Foundation stated, “The new energy cost better reflects computational resources and promotes efficient network usage.”
Developers will need to calculate energy requirements for contracts using SELFDESTRUCT. Updating contract design may prevent failed transactions or unexpected errors.
Voting for TRON Proposal No. 106 has been initiated.

Nodes that do not upgrade software could face issues executing these transactions.
Running the latest node ensures all energy costs are correctly applied. This will help the network remain stable while handling SELFDESTRUCT operations.
In addition, developers should plan energy budgets for frequent contract deletions.
Proper planning avoids transaction failures and ensures smooth operation. The update encourages careful resource management across the network.

Node Upgrades and Developer Preparations
All TRON nodes should upgrade to version 4.8.1 before the network implements the proposal.
This upgrade ensures the network applies SELFDESTRUCT rules correctly. Without the update, nodes may face synchronization errors or failed transactions.
Developers must also review existing smart contracts, especially those relying on immediate deletion.
Testing on test networks can confirm that asset transfers work as intended.
This proposal also helps improve interoperability with Ethereum-based systems.
By aligning contract behavior, developers can port contracts between TRON and Ethereum more easily.
It simplifies cross-chain integration and ensures consistent contract execution.
Voting for Proposal 106 is now open, and TRON stakeholders can cast votes to approve or reject it.
Participants should stay updated with announcements from the TRON Foundation.
Preparing contracts and nodes ahead of time will ensure smooth implementation.
