Hedera is set to upgrade its mainnet to version 0.63 on July 23, 2025, at 17:00 UTC. This scheduled maintenance is expected to last about 40 minutes and may temporarily slow transaction processing across the network. The update's primary goal is to enhance system operations and network performance, without altering HBAR tokenomics or smart contract execution.
The mainnet upgrade includes three significant changes: support for non-zero shard and realm IDs in system commands, fee configuration throttling to add rate-limiting on administrative changes, and MerkleDB tuning to improve node storage efficiency and reduce processing overhead. These improvements aim to boost resilience and operational flexibility for developers and node operators. Additionally, Hedera CLI tools such as yahcli will now support custom network partitions, expanding Hedera’s capacity for enterprise deployments. The upgrade will also increase the network’s throughput and shorten ledger syncing time.
Regarding HBAR utility, the upgrade does not introduce any direct changes. Core functions like transfers, staking, smart contract gas fees, transaction fees, and staking mechanisms will remain unchanged. Users might experience temporary delays or halted transactions during the upgrade window, but normal operations will resume after the maintenance.
HBAR has experienced a surge of over 100% this month, climbing from approximately $0.15 to around $0.28–$0.29 as of July 21. Analysts highlighted a bullish technical setup, noting the formation of a golden cross and strong exchange inflows supporting the momentum. Although the short-term Relative Strength Index (RSI) suggests HBAR may be overbought, broader sentiment continues to be positive, with resistance expected between $0.37 and $0.50 if the upward trend persists.
The Hedera v0.63 upgrade is primarily a technical maintenance release, rather than a feature launch or tokenomics revision, making it unlikely to directly influence price movements. However, the stability and reliability improvements could bolster investor confidence, especially following the recent price volatility. A smooth upgrade could help maintain the current price range by reducing technical risk, but significant price changes will probably be driven by broader market factors and upcoming ecosystem developments, rather than the upgrade itself.
Investors and traders should monitor network stability during the rollout and remain attentive to wider market signals to anticipate HBAR’s next moves. While the upgrade may support the bullish trend, it is not expected to act as a primary catalyst for further price action.
