- Hedera has expanded the agent kit to now support Google’s ADK and Gemini models.
- The expansion will encourage developers to build and execute protocols on the network.
Hedera has launched version 4 of the Hedera Agent Kit with new features that enable developers to build agent guardrails. One of the most highlighted features is its integrations with Google’s ADK. With this new feature, developers can build Hedera-powered AI agents directly within Google’s ecosystem.
The Hedera Agent Kit plugin ecosystem keeps growing, with x402, Google ADK support and more.
V4 brings hooks, policies, a refactored tool architecture, and third-party plugins for price feeds, identity verification, and currency conversion. 👇https://t.co/mkQJOQiCv9

Hedera supporting Google’s ADK and Gemini models is one of the biggest expansions in the ecosystem. It means that Hedera is now compatible with Google AI tooling, agentic AI workflows, and Gemini-powered applications.
Hedera Builds Enterprise-Safe AI Agents
The new release focuses on guardrails for AI agents. The team notes that the new release allows developers to build using a hook-and-policy system. This ensures there are no unsafe spending or unauthorized transactions, allowing developers to set spending limits, create audit trails, and block transactions.
Hedera has also expanded its plugin library and now enables agents to access up-to-date price data, identity verification services, compliance tools and more. Some of the most notable third-party plugin extensions include Chainlink, CoinCap, and Pyth.
Additionally, Version 4 breaks the old monolithic SDK into modular packages. The JavaScript SDK has moved from the old @hashgraph/sdk package to a new open-source home maintained by Hiero. Developers now need to import it using @hiero-ledger/sdk instead.
The team also revealed that the Hedera exact payment scheme has been accepted into x402. This is an open standard for internet-native payments developed by Coinbase that empowers agentic payments at scale. This will help in supporting AI monetization, autonomous API payments, and internet-native commerce.
The announcement sees Hedera double down on auditability and compliance to target regulated industries, financial institutions, and enterprise AI deployments.
The team has called on developers to participate in the Hedera AI Agent Bounty that was announced on Monday. A new bounty drops every Monday, and developers can pick what fits them, build it, ship it as a public GitHub repo using Hedera Agent Kit, and stand a chance to win HBAR. This is a key initiative that could lead to the launch of products with real-world utility and ultimately drive network adoption.
HBAR Rallies Following Upgrade
Hedera’s HBAR coin has reacted positively to the new developments, adding to 2% in the last 24 hours. The coin is trading for $0.09032 at the time of writing. In the past couple of months, prices have been stuck in a tight range with long-term holders taking advantage to accumulate.
Some analysts expect a breakout soon that aligns with the network, which has been working on long-term infrastructure. As ETHNews has reported, Hedera has repeatedly topped the top Real World Asset (RWA) crypto projects by development activity.
