[Standard] Tron - Mainnet and Nile Testnet - Upgrade to v4.8.2.2

Scheduled for Sep 21, 00:00 - 04:00 UTC

Scheduled

We are upgrading our Tron Mainnet infrastructure to v4.8.2.2 and our Tron Nile Testnet infrastructure to v4.8.2.2-PQ1-build1. This is a mandatory upgrade issued by the Tron Foundation, applying to both mainnet and Nile testnet.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- Contract deployment transactions now go through refined validation, improving consistency and reliability for users deploying smart contracts. Stake 2.0 and SELFDESTRUCT instruction handling has been optimized for edge cases, improving consistency of contract execution results for affected calls.
