Fact Check
Every element of the claim is confirmed by three official primary sources. The TRON Developer announcements page and the official @trondao X post both state GreatVoyage-v4.8.2 (Pyrrho) is a mandatory upgrade to be completed by 23:59 SGT on August 16, 2026, adding TVM compatibility with Ethereum Pectra and Osaka, API/security/node-performance improvements, and instructing Event Plugin users to move to v3.0.0 first. The official java-tron GitHub release notes independently confirm the mandatory status, the Ethereum Osaka/Pectra adaptations, the security and core improvements, and the Event Plugin v3.0.0 prerequisite. A secondary news report corroborates the same facts.
Summary

TRON DAO has released GreatVoyage v4.8.2, also called Pyrrho, as a mandatory upgrade for the TRON blockchain. Node operators have until August 16, 2026, 23:59 SGT to install it or risk disruption to block synchronization, and operators using the Event Plugin are advised to upgrade that software to version 3.0.0 before installing the node update. The release is designed to strengthen Ethereum compatibility, protocol security and node operations. It aligns TRON Virtual Machine with Ethereum’s Pectra and Osaka upgrades, adds support for the CLZ opcode and Secp256r1 signature validation, and introduces changes aimed at helping developers build dApps while maintaining compatibility with Ethereum standards. The upgrade also includes TIP-2935 for historical block hash storage, along with changes to MODEXP pricing and limits, calldata verification, execution safeguards and time restrictions for contract calls. TRON DAO said the release also modernizes the API layer by replacing fastjson with Jackson and improves JSON-RPC compatibility, framing the upgrade as a broader infrastructure push to improve security, operational reliability, Ethereum interoperability and developer experience.
