Funds remain yours. Customer funds stay safe and accessible. Ownership of funds and assets is unchanged.
Deadline: October 31, 2026. Users who do not wish to continue with Onyx should complete transfers or closures by this date.
Today, we are announcing the completion of an important milestone for Chain and the beginning of the next chapter for the technology and services we have built over the years.
Onyx has completed its acquisition of the Chain technology platform and associated technology and intellectual property. As part of the transaction, the technology that has powered Chain's products and services will become part of the broader Onyx ecosystem.
With the acquisition now completed, services currently offered through Chain.com will begin transitioning to Onyx. This transition is intended to consolidate the underlying technology, infrastructure, and supported services within the Onyx ecosystem, while providing existing Chain users with an orderly migration process.
What this means for existing Chain users
Existing Chain customers and users will be transitioned to the Onyx platform for services that Onyx elects to continue supporting following the acquisition.
Users with active accounts or services do not need to immediately take action solely to initiate the migration. Existing users will be automatically migrated as part of the transition process where applicable. Additional information regarding account access, supported services, and any actions required from individual users will be communicated during the migration period.
Most importantly, customer funds remain safe and accessible throughout the transition. The acquisition and migration process does not change users' ownership of their funds or assets.
We recognize that continuity and access are particularly important whenever financial and technology platforms undergo a transition. Chain and Onyx are working to provide users with sufficient time to review their options and complete any necessary actions.
Transition period through October 31, 2026
Existing Chain users will have until October 31, 2026 to finalize any required account or service transitions.
During this period, Chain and Onyx will work to migrate eligible accounts and supported services to the Onyx platform. Users should monitor communications associated with their Chain accounts for information regarding specific services, migration requirements, account access, and any changes resulting from the transition.
Certain Chain services may be incorporated into corresponding Onyx products, modified as part of the integration, or discontinued as Onyx consolidates the acquired technology into its broader platform.
Where a Chain service will continue under Onyx, existing users will receive information regarding how that service will operate following the transition, and whether any additional steps are required.
Users may choose not to migrate
While existing users will be migrated automatically where applicable, customers are not required to continue using services following the transition to Onyx.
Any user who does not wish to migrate or continue receiving services through Onyx may cancel their existing services and transfer their funds, assets, or applicable services to another provider, subject to the normal terms, processing requirements, and applicable legal or regulatory requirements associated with their account.
Users who choose to discontinue their services should complete any necessary transfers or account closures before October 31, 2026.
Our objective is to provide customers with adequate time to determine which option is appropriate for them, while maintaining an orderly transition of the Chain platform.
The next chapter for Chain technology
Chain has spent years building technology at the intersection of blockchain infrastructure and financial services. The platform has expanded across digital assets, wallets, payments, stablecoins, financial accounts, ledger infrastructure, settlement technology, fiat connectivity, and other services designed to connect traditional and blockchain-based financial systems.
The acquisition by Onyx provides an opportunity for that technology to become part of a significantly broader blockchain and financial ecosystem.
Onyx intends to integrate acquired Chain technology into its growing financial technology stack, including its Onyx Layer 1 blockchain and Onyx Wallet ecosystem. The combination creates an opportunity for technology originally developed at Chain to support a new generation of blockchain-native financial products and services.
For Chain, this represents both a transition and an evolution.
The technology and infrastructure developed through Chain will continue forward as part of Onyx, while the Chain.com service environment will transition as products and infrastructure are migrated, consolidated, or integrated into the Onyx ecosystem.
Moving forward
We understand that transitions involving financial services and technology require clear communication. Chain and Onyx will provide additional information to existing users as the migration progresses, including details regarding supported services, account access, migration procedures, and any actions users may need to take.
Existing users should continue to monitor their registered email addresses and official communications for service-specific instructions.
To summarize: Onyx has acquired the Chain technology platform, and Chain.com services will now begin transitioning to Onyx. Existing users will be automatically migrated where applicable, customer funds remain safe, and users will have until October 31, 2026 to complete any necessary transition.
Users who prefer not to continue with Onyx may cancel their services and transfer to another provider during the transition period.
We are grateful to every customer, developer, partner, and organization that has used and supported Chain over the years. What began as an effort to build better infrastructure for digital assets and financial technology is now becoming part of a larger ecosystem designed around the convergence of blockchain and financial services.
We look forward to seeing the technology built at Chain continue its next chapter as part of Onyx.
