Hedera lines up a mainnet upgrade, expands agent tooling, wraps Sibos outreach, and features in Australia’s wholesale-CBDC trials. The network’s public status page lists a mainnet upgrade to v0.66 on Wednesday, October 8, 2025 at 17:00 UTC.
Separately, Hedera published a deep dive on its new Hedera Agent Kit and posted September developer highlights. The team also concluded its Sibos 2025 presence in Frankfurt. Finally, Australia’s Project Acacia trials cite Hedera among test platforms for wholesale digital money.
Mainnet upgrade scheduled for October 8
Hedera scheduled a mainnet upgrade to v0.66 for October 8 at 17:00 UTC. The status page notes an expected window of about 40 minutes with possible service disruption. This follows a testnet move to v0.66 completed in late September.
The upgrade notice appears both on the Hedera status portal and mirrored via the @HederaStatus channel on X. The entries identify version numbers, timing, and disruption expectations in plain terms.
As of today, the incident history shows no unresolved items for October. Hedera typically uses these notices to flag scheduling and completion states for nodes and networks.
Hedera published a deep dive on the Hedera Agent Kit on October 1, outlining plugins, workflows, and examples for agent-driven apps that interact with HTS/HCS and accounts. The post sits alongside prior notes indicating a re-architected Agent Kit V3 this year.
The blog focuses on practical integration, showing how agents can sign, submit, and verify actions on Hedera with minimal glue code. It positions the kit for builders who want automated actors to coordinate tasks on-chain.
In parallel, Hedera’s September Developer Highlights recap adds links to AI Studio updates, the Hello Future: Ascension hackathon registration (starts November 3), and the latest technical community call.
Sibos 2025: booth program and closeout
Hedera staffed booth DISM67 at Sibos 2025 in Frankfurt from Sept 29–Oct 2, showcasing tokenization, cross-border payments, real-time treasury, digital identity, and AI demos.
Event listings also recorded Hedera booth sessions and a reception on October 1, confirming an active agenda throughout the conference.
Hedera’s channels marked on-site presence during the week with images and location details, then transitioned to an October events slate across Madrid, Dallas, Dubai, London, Washington DC, and more.
Australia’s Project Acacia: Hedera among trial platforms
The Reserve Bank of Australia (RBA) and DFCRC launched Project Acacia trials in July 2025 to test wholesale digital money and tokenized asset settlement. Official communications and major-media coverage list Hedera among the platforms used in pilot use cases. Findings are due in 1H 2026.
The trial spans CBDCs, stablecoins, bank deposit tokens, and existing exchange bank accounts at the RBA, with 19 real-money pilots and five proofs-of-concept. The program targets improvements in operational risk, costs, transparency, and collateral efficiency in wholesale markets.
Participating institutions include three of Australia’s major banks alongside fintechs and regulators with ASIC-granted relief for testing. The scope positions Hedera within regulated, production-style experiments rather than lab-only PoCs.
Standards and naming: HIPs presented under “Hiero”
Hedera’s public HIPs site nowdisplays as “Hiero Improvement Proposals.” The portal and GitHub repositories describe HIPs as the primary mechanism to propose features and document design decisions for the Hiero codebase.
Documentation pages explain the process and show recent HIPs, including interface changes and service updates that affect developers. Release notes reference the Hiero naming in metrics and components.
This presentation aligns with 2024 materials announcing Hiero under the Linux Foundation Decentralized Trust, where the open proposal process mirrors prior Hedera HIP norms.
Ecosystem operations: HeliSwap sunset date
HeliSwap, a Hedera DEX, announced it will sunset operations on October 30, 2025 and asked users to withdraw funds before that date. The team communicated the decision publicly on X.
Community threads echo the timeline and discuss token program implications and treasury positions. The project’s earlier profiles had described it as a multi-asset DEX on Hedera.
Therefore, users interacting with HeliSwap should plan migrations and check official channels for the final cut-off procedures and links.
Analyst flags “HBAR compression” on daily chart
An X post from Steph_iscrypto highlights a compression pattern on Hedera’s daily chart. The shared image shows price oscillating inside a downward-sloping channel since mid-summer, with candles crowding toward the lower boundary. The Bollinger Bands narrow around the range, signaling reduced volatility.
In the chart, dotted levels mark mid-channel reactions while wicks test both rails. Moreover, the rightmost cluster sits near the channel base, where prior rebounds began. The overlay includes a projected path higher, indicating the author’s view of a potential release after compression.
Context matters. The setup follows a sharp July advance, then months of contained drift. Therefore, traders often watch for breaks beyond the channel or a rejection at its edges to define direction. The post frames the current structure as “compression,” drawing attention to tightening bands and a coiled range without citing specific targets.
Analyst maps falling-wedge setup; $0.20 flagged as support
Crypto Chiefs posts a dailyHBAR/USD chart showing Hedera in a narrowing falling-wedge structure from July’s impulse. Candles press between descending trendlines, with higher reaction lows near the lower rail and lower highs under the upper rail. The note favors a bounce, citing $0.20 as firm support.
The chart places price just below the wedge midpoint after a brief pullback. Therefore, upside confirmation would come from a clean break and daily close above the upper trendline, followed by acceptance on retest. In that case, traders typically measure the prior swing height inside the wedge to size potential follow-through.
However, risk remains if sellers drive a daily close beneath the lower boundary. That move would invalidate the compression bias and reopen the July gap area toward the mid-$0.19 region shown on the chart. Until a break occurs, the setup records contracting volatility and a clear decision zone.
