TRON proposal 106 approved Before now, there was a function called SELFDESTRUCT. A delete button for smart contracts. You could deploy a contract, use it, and then completely remove it from the blockchain. That behavior is changing. Now, a contract can only fully delete itself if it does so in the exact same transaction it was created in. If not, the contract doesn’t disappear anymore. Instead: ⇛ Any funds inside can still be moved out ⇛ But the contract itself stays on-chain permanently So the delete button isn’t really a delete button anymore. It’s more like a withdraw and leave behind function. There’s also a cost change. Using SELFDESTRUCT used to be free. Now it costs energy (5000). Why this matters: 1️⃣ predictability. Contracts sticking around makes the network easier to reason about. Things don’t just vanish anymore after interacting with them. 2️⃣ security. Some patterns relied on creating and deleting contracts in ways that could be abused or misunderstood. This change removes a lot of that ambiguity. 3️⃣ alignment. TRON is bringing its behavior closer to Ethereum, which makes life easier for developers moving between both ecosystems. If you’re a developer, you’ll want to revisit anything that depends on deleting contracts. Some designs simply won’t work the same way anymore. If you’re just using apps on TRON, nothing breaks but in the background things just got more stable and easier to maintain long term. This is one of those updates that doesn’t look flashy, but improves how the network behaves over time. @justinsuntron @trondao #TRONEcoStar
