The IOTA ecosystem continues to evolve with the release of testnet version v1.15.0-rc, introducing protocol version 18 and several enhancements across the protocol, nodes, and developer tools. This update brings exciting changes, including the deployment of IOTA Names on the mainnet and the launch of a new Move-based IOTA EVM testnet. Builders and stakers should take note of these updates to stay ahead of upcoming changes and ensure smooth transitions.

Highlights this week

• Protocol version 18 introduced in testnet v1.15.0-rc.
• IOTA Names deployed on the mainnet for enhanced identity and naming capabilities.
• New IOTA EVM testnet launched, requiring migration from the old testnet within two months.
• Experimental --rest-kv-url CLI argument added for improved indexer fallback handling.
• Bug fixes for JSON-RPC methods, including iotax_getTimelockedStakes and move-call argument resolution.
• Enhancements to GraphQL, including new fields for event and package data.

Testnet and prerelease notes

The latest testnet release, v1.15.0-rc, introduces protocol version 18, paving the way for improved functionality and new features. One of the standout updates is the deployment of IOTA Names on the mainnet, which allows for streamlined identity management and naming services across the network. This feature is expected to enhance user experience and simplify interactions within the IOTA ecosystem.

Additionally, the new Move-based IOTA EVM testnet is now live, offering builders a robust environment to develop and test decentralized applications. This testnet is directly connected to the IOTA L1 Rebased testnet and introduces Chain ID 1076. Builders currently using the old testnet should begin migrating their deployments to the new environment, as the old testnet will be deprecated in two months. Key endpoints for the new testnet include:

• Explorer: https://explorer.evm.testnet.iota.cafe/
• JSON-RPC: https://json-rpc.evm.testnet.iota.cafe
• WebSocket: wss://ws.json-rpc.evm.testnet.iota.cafe

Developers are encouraged to review the full release notes for detailed information on the changes and prepare for the transition.

Why this matters for stakers

For stakers, these updates are more than just technical improvements—they represent key steps toward a more robust and user-friendly ecosystem. The introduction of IOTA Names on the mainnet simplifies interactions by enabling human-readable identifiers, which could lead to increased adoption and ease of use for staking and other activities. Additionally, the new testnet ensures that developers can build and test applications in a more stable and forward-compatible environment, ultimately benefiting the entire network, including stakers.

The migration to the new Move-based IOTA EVM testnet is particularly significant. This step ensures compatibility with the latest protocol advancements and provides a seamless path for future innovations. Stakers should stay informed about these changes, as they may impact the tools and platforms used for staking and interacting with the IOTA network. For those looking to maximize their staking rewards, tools like the APY Calculator and Staking Tracker can help optimize strategies during this transition.

The bottom line

The v1.15.0-rc testnet release is a significant milestone for the IOTA ecosystem, introducing protocol version 18, IOTA Names on the mainnet, and a new Move-based EVM testnet. Builders and stakers alike should take note of these updates and prepare for the upcoming changes, including the migration to the new testnet. As IOTA continues to innovate, staying informed and adapting to these advancements will be key to maximizing the benefits of participation in the network.
