The completion of JasmyChain's mainnet migration means that the network has transitioned from a testing environment to a production-ready phase. Developers and users can now deploy smart contracts, execute transactions, and run applications on JasmyChain under real economic conditions.

JasmyChain is an Ethereum-compatible Layer 2 network built using the Arbitrum Orbit framework and the Arbitrum Nitro stack. It aims to balance EVM compatibility, faster execution, and lower fees compared to the Ethereum mainnet.

Jasmy indicates that production operations will begin following the announcement of testnet verification results in August 2025. These results reflect extensive testing under real-world conditions, including periods of high transaction volume and network congestion.

Why did Jasmy create JasmyChain?

JasmyLab Inc. is headquartered in Tokyo's Minato Ward, focusing on decentralized GPU cloud infrastructure and blockchain development. According to the company, the development of JasmyChain aims to provide a foundation suitable for AI and Web3 applications, where on-chain activity may be heavy and cost-sensitive.

Many AI-related use cases require frequent transactions, data validation, and cross-service coordination. Running these workloads directly on the Ethereum mainnet can be costly and unpredictable. JasmyChain aims to reduce these frictions while maintaining compatibility with existing Ethereum tools.

The choice of Arbitrum Orbit allows Jasmy to customize network parameters while still relying on Ethereum for security and settlement.

How was the mainnet prepared during the test network phase?

Before the mainnet launch, JasmyChain underwent a test network phase throughout 2025. The focus extended beyond performance benchmarking to operational readiness.

JasmyLab assessed several areas during testing:

  • Network stability during high transaction volumes

  • Fee behavior and gas cost predictability

  • Latency, retry behavior, and RPC reliability under peak loads

  • Wallet connection process and transaction confirmation experience

  • Monitoring, logging, alerts, and recovery procedures

  • Secure operations and event response preparedness

  • Developer feedback related to tools, documentation, and samples

This testing approach reflects lessons learned from early Layer 2 launches across the Ethereum ecosystem, where operational gaps only surface after actual usage begins.

What are the core features of the JasmyChain mainnet?

The JasmyChain mainnet introduced several features that define how the network operates and how developers interact with it.

Arbitrum Orbit-based aggregation architecture

JasmyChain is built using Arbitrum Orbit, allowing teams to deploy customized Layer 2 or Layer 3 chains to solve Ethereum's scalability issues. The chain utilizes the Arbitrum Nitro stack, compatible with Ethereum's execution environment while improving throughput and reducing execution costs.

This design allows JasmyChain to inherit Ethereum's security model while maintaining flexibility in network configuration.

JASMY as a custom gas token

JasmyChain uses JASMY as its native gas token. Arbitrum Orbit allows any ERC-20 token to be used for gas, and Jasmy chose JASMY to directly link network use with the token's utility.

Gas fees paid in JASMY are used to execute transactions on the network, making the token an essential part of daily activities rather than a passive asset.

Complete EVM compatibility for developers

Due to JasmyChain's EVM compatibility, developers can deploy existing Solidity smart contracts with minimal changes. Common Ethereum development tools, such as wallets, RPC providers, and deployment frameworks, can be used without the need for custom integration work.

This lowers the barriers for teams already building on Ethereum or other Layer 2 networks to experiment or migrate to JasmyChain.

Design prepared for account abstraction

The architecture of JasmyChain considers future abstract features. These include gas sponsorship models, enterprise 'gas station' setups, and onboarding processes similar to Web2 user experiences.

Account abstraction allows users to interact with blockchain applications without directly managing traditional gas payments or private keys. While these features are not yet fully deployed, the network design anticipates their integration.

What tools are available on JasmyChain today?

After the mainnet migration, several core tools are now available for users and developers.

Block resource manager access

JasmyChain runs a mainnet block explorer that allows users to view transactions, addresses, and smart contracts. This is a standard requirement for transparency and debugging in any production blockchain network.

Wallet integration and network details

Users can add JasmyChain to major EVM-compatible wallets using the following parameters:

  • Network Name: JasmyChain

  • Chain ID: 680

  • RPC URL: https://rpc.jasmychain.io

  • Gas Currency: JASMY

  • Block Explorer: https://explorer.jasmyscan.net

This allows sending, receiving, and executing transactions directly on the network.

Bridge support via Arbitrum Portal

JasmyChain can be accessed via the Arbitrum Portal, allowing users to connect assets between the Ethereum and JasmyChain networks using established Arbitrum infrastructure.

The launch of the JasmyChain mainnet follows early product development by JasmyLab, including the launch of JANCTION LINK in October. JANCTION LINK is a web-based service that aggregates links from social platforms and websites into a single URL while tracking engagement metrics like video watch time.

The service addresses content fragmentation between platforms like X, Instagram, and YouTube by allowing creators to direct audiences to a consolidated page. Engagement is measured numerically, providing creators and organizations with clearer signals about audience behavior.

JANCTION LINK runs entirely in the browser, requiring no separate application, which aligns with JasmyLab's focus on usability and integration with existing toolsets.

What can the mainnet migration achieve?

With the launch of JasmyChain, the network can support applications that require consistent execution costs, high transaction throughput, and Ethereum compatibility. These features are particularly relevant to AI-related workloads, decentralized data services, and applications with frequent on-chain interactions.

The migration also signifies that JasmyChain has moved beyond experimental status into operational maturity, establishing monitoring, security, and recovery systems.

Conclusion

JasmyChain has completed its mainnet migration and is a fully operational Layer 2 built on Arbitrum Orbit, compatible with EVM. The network uses JASMY as a custom gas token, supports standard Ethereum development tools, and aims to handle high transaction volumes with predictable fees.

After extensive testing network validation, JasmyChain now provides a real-time execution environment supported by established Layer 2 infrastructure. This release aligns with JasmyLab's broader focus on decentralized infrastructure, data usage, and practical blockchain deployment.
