TRON DAO has approved a significant protocol-level change, as Proposal No. 106 introduces updates to the behavior and cost of the SELFDESTRUCT opcode within the TRON Virtual Machine (TVM), marking another step toward deeper compatibility with Ethereum and its broader developer ecosystem. The proposal fundamentally alters how SELFDESTRUCT functions by restricting full contract deletion to only those cases where it is executed within the same transaction as contract creation, while in all other scenarios, the opcode will now simply transfer assets without removing the contract from the blockchain. This change represents a shift away from legacy behavior that allowed contracts to be permanently removed under a wider range of conditions, bringing TRON’s execution environment more in line with Ethereum’s evolving standards, particularly as Ethereum itself has moved to limit the destructive capabilities of this opcode in favor of greater state consistency and predictability.
TRON Proposal No. 106 has been approved.

🔺Contract will only be deleted if executed in the same transaction as creation
🔺Otherwise, only asset transfer occurs while the contract remains on-chain

At the same time, the proposal introduces a notable adjustment to the energy cost associated with SELFDESTRUCT, increasing it from zero to 5000, effectively discouraging unnecessary or abusive use of the opcode while ensuring that it reflects the computational and state-related implications of its execution. This is an important consideration in blockchain design, as underpriced operations can lead to inefficiencies, spam, or unintended economic incentives that degrade network performance. By recalibrating both the functionality and cost of SELFDESTRUCT, TRON is not only improving technical alignment with Ethereum but also refining its internal economic model to better manage resource usage across the network.
A Step Toward Greater EVM Compatibility
One of the most important aspects of Proposal 106 is its impact on interoperability and developer experience, as aligning TVM behavior more closely with Ethereum makes it easier for developers to port applications, tools, and smart contracts between the two ecosystems. In a multi-chain environment where developers are increasingly building across multiple platforms, consistency in core opcode behavior reduces friction and minimizes the risk of unexpected outcomes when deploying or interacting with contracts on different networks. By adopting similar constraints on SELFDESTRUCT, TRON DAO is effectively signaling its intent to position TRON as a more EVM-compatible environment, capable of attracting developers who are already familiar with Ethereum’s architecture.
This alignment also reflects a broader trend in the industry, where many layer-1 networks are converging around Ethereum’s standards, not necessarily because they lack innovation, but because the network has established a de facto baseline for smart contract development. For TRON, which already hosts a significant share of stablecoin activity and decentralized applications, improving compatibility can help strengthen its competitive position by making it a more accessible and predictable platform for developers looking to expand beyond Ethereum without completely reworking their codebases.
What Developers and the Ecosystem Need to Know
For developers currently building on TRON DAO, the changes introduced by Proposal 106 are not merely theoretical, but require practical adjustments to how smart contracts are designed and deployed, particularly for those that rely on SELFDESTRUCT as part of their logic. Since contracts will no longer be deleted in most cases, developers must account for the persistence of contract state and ensure that their applications handle asset transfers and lifecycle management appropriately under the new rules. This may involve revisiting existing code, updating deployment strategies, and testing edge cases to avoid unintended behavior once the changes are fully implemented.
From a broader ecosystem perspective, the proposal contributes to a more stable and predictable execution environment, which is essential for long-term growth and adoption, especially as more complex applications and financial systems are built on top of blockchain infrastructure. By reducing the potential for unexpected contract deletion and aligning costs with actual resource usage, TRON is taking steps to enhance both security and efficiency, two factors that are critical for maintaining trust among users and developers alike. While these changes may introduce short-term adjustments for developers, they ultimately support a more robust and scalable ecosystem capable of supporting a wide range of use cases.
Final Take
The approval of Proposal 106 by TRON DAO marks a meaningful evolution in the network’s technical framework, bringing its SELFDESTRUCT behavior closer to that of Ethereum while also refining its internal cost structure. This move underscores TRON’s broader strategy of enhancing compatibility, improving efficiency, and aligning with industry standards to remain competitive in an increasingly interconnected blockchain landscape.
For developers, the message is clear: adapt to the new rules and take advantage of a more consistent and predictable environment, while for the ecosystem as a whole, this change represents another step toward a more mature and interoperable future. As blockchain networks continue to evolve, decisions like these will play a crucial role in shaping how easily value and applications can move across chains, ultimately influencing the direction of the entire industry.
