Hedera Testnet Upgrade to v0.62.6

Hedera, a decentralized public network powered by the hashgraph consensus algorithm, will upgrade its testnet to v0.62.6 on June 3, 2025, at 17:00 UTC. This 40-minute upgrade will temporarily disrupt testnet services, allowing developers to test new functionalities in a controlled environment before mainnet deployment. The upgrade aims to enhance transaction efficiency, smart contract capabilities, and developer tools, aligning with Hedera’s mission to provide a scalable, enterprise-grade platform for decentralized applications (dApps). This testnet release is a critical step toward ensuring stability and performance for future mainnet updates, reinforcing Hedera’s position as a leader in distributed ledger technology (DLT).

Recent News

Hedera has been making waves in 2025! In May, the mainnet successfully upgraded to v0.61.10, improving transaction throughput and network stability. The Hedera Governing Council, comprising global giants like Deutsche Telekom and IBM, transferred the hashgraph source code to the Linux Foundation’s Hiero project in September 2024, making it open-source under the Apache License. This move has boosted developer accessibility and community trust. Additionally, Hedera’s partnerships with enterprises like Avery Dennison and ServiceNow highlight its growing adoption in real-world use cases, from supply chain tracking to tokenized asset management.

Future Plans

Hedera’s roadmap is packed with ambitious goals. The network is working toward permissionless nodes via the Node Management Tool (NMT), which will decentralize node operations and enhance security. Upcoming features include EIP-4337 compatibility for Ethereum-like smart contracts and batch transaction support for complex workflows without relying on smart contracts. Hedera also plans to introduce scalability features like sharding and blockstream APIs, ensuring the network can handle growing transaction volumes for enterprise and DeFi applications. These advancements position Hedera to compete with major players like Solana and Ethereum.

Onchain Data

Hedera’s network performance is impressive. The mainnet processes over 10,000 transactions per second with sub-3-second finality, outpacing many traditional blockchains. As of June 9, 2025, HBAR’s circulating supply is 42.24 billion out of a 50 billion max supply, with a market cap of $7.54B USD. Recent 24-hour trading volume reached $125.44M USD, reflecting strong market activity despite a 7% price dip. Onchain analytics from platforms like Hashscan show consistent growth in account creation and dApp usage, particularly in DeFi and NFT marketplaces.

Community Sentiment

The Hedera community on X is buzzing with excitement about the testnet upgrade. Posts highlight optimism about Hedera’s enterprise adoption and unique features like scheduled transactions, which enable escrow-like functionality for DePIN (Decentralized Physical Infrastructure Networks). Influencer @kevinolearytv, a self-proclaimed “big shareholder” in HBAR, recently praised Hedera’s potential to revolutionize digital payments, boosting community morale. However, some users express caution about HBAR’s recent price volatility, urging due diligence before investing.

Why It Matters

This testnet upgrade is a pivotal moment for Hedera, ensuring its infrastructure remains robust and developer-friendly. By refining smart contract tools and transaction efficiency, Hedera strengthens its appeal for enterprises and developers building high-throughput dApps. The open-source Hiero project and growing partnerships further cement Hedera’s role as a trusted DLT platform. While price volatility is a risk in crypto markets, Hedera’s fixed fees and carbon-negative network offer stability for users.
