Unichain升级公告：测试网与主网迁移详情

Unichain 升级至 OP Enterprise：测试网与主网迁移日期公布

该网络宣布了一项重大的基础设施变更，这可能使跨链资产转移变得更加简单。Unichain 升级将网络迁移至 OP Enterprise。测试网将于 10 月 13 日迁移，主网则于 2026 年 10 月 29 日跟进。用户最关心的问题在于他们是否需要采取任何行动，以及无桥接传输功能何时真正上线。

快速概览

• Unichain 升级：正在向 OP Enterprise 迁移，为 OP Stack 链之间的原生互操作性做准备。
• 测试网迁移：2026 年 10 月 13 日。
• 主网迁移：2026 年 10 月 29 日。
• 预期收益：一旦互操作性上线，用户可以在 OP Stack 链之间移动资产（首先支持以太坊 ETH），无需使用桥接。
• 保持不变：链 ID、智能合约、用户余额、应用程序以及 Uniswap v2、v3 和 v4 部署。

什么是 Unichain 升级？为何要进行此次升级？

Unichain 升级于 10 月 9 日宣布。其目标是为网络在 OP Stack 上实现原生互操作性做好准备，OP Stack 是许多 Optimism 关联链背后的共享技术。

The upgrade extends Optimism's financial infrastructure to Unichain. After that, users will be the first to gain native interoperability and access to newly released versions of OP Stack.

Migration and interoperability releases are two separate milestones. Migrating to OP Enterprise itself will not directly turn on bridgeless transport.

Unichain Migration Schedule: Key Dates

This migration is divided into two phases. First there is the test network, then the main network.

Milestone Date Meaning Announcement October 9, 2026 Update reveals migration to OP Enterprise's mobile test network October 13, 2026 Test network migration to new stack Mainnet Migration October 29, 2026 Real-time network migration to OP Enterprise Native interoperability release pending After the unbridged transport function was launched Early posts stated that the mainnet will be on the "Follow up in late October." Subsequent full announcements set the exact date as October 29.

What is the impact on users after migration?

The main changes occur in the background. The network will run on Optimism Enterprise, replacing its current settings, preparing for the new OP Stack feature.

一旦互操作性上线，用户应能够在 Unichain 和其他 Stack 链之间发送受支持的资产，而无需使用桥接。ETH 将是第一个支持的资产。但这并不意味着第一天就能支持所有代币或所有链，因此支持范围取决于上线时的具体情况。

哪些内容保持不变？

链 ID、智能合约、余额以及网络上的每个应用程序和协议都保持不变。这包括 Uniswap v2、v3 和 v4 的部署。

它仍然是一个具有无权限故障证明的第 1 阶段滚动层（Rollup）。合约升级仍由 Optimism 治理和安全委员会管理，这与当前情况一致。

上述要点描述了计划的范围。用户仍应密切关注官方渠道，以获取临近日期时的任何操作指示。

原生互操作性如何改善转账体验？

长期以来，桥接一直是跨链转移资产的标准方式。根据所使用的桥接服务不同，用户可能会面临额外的步骤、费用、等待时间以及安全风险。

Native interoperability is designed to reduce friction between chains participating in Stack. For users, this may mean faster access to applications on other chains. Still,"no bridges" does not mean "no risks". Users should carefully check network details, supported assets, and official availability before sending funds.

What role will Optimism play?

Optimism will run the production environment stack. This covers sequencers, RPC services, monitoring, and event responses for the main and test nets. Sorters are responsible for sorting transactions;RPC services allow wallets and applications to communicate with the network; and monitoring and event response help keep the network stable. For users, this is an operational-level change, not a transfer of balances or a replacement of existing applications.

What should users and developers do before October 29?

The announcement does not require users to transfer funds or create new wallets. Even so, it can help to develop the following habits:

• Follow Unichain's official channels for the latest updates.
• Ignore unofficial claims that interoperability is already online.
• Check the network and supported assets before making any cross-chain transfers.

Developers should read the compatibility instructions in the official documentation.

Conclusion

The Unichain upgrade is a step towards Stack native interoperability. The test network will migrate on October 13, and the main network will migrate on October 29, 2026. Balances, contracts, applications and Uniswap deployments are expected to remain unchanged. Please view the migration date as a milestone rather than the launch date of the unbridged ETH transfer feature. Please wait for official confirmation of this feature.
