Sentosa upgrade rescheduled by 24 hours

As part of our final pre-deployment checks for the Sentosa upgrade, we identified a non-critical behaviour in how the new runtime interacts with certain infrastructure setups used by ecosystem partners and node operators. To allow for additional validation and coordination with these partners, we are postponing the Sentosa Mainnet upgrade window by 24 hours.

The Enjin Blockchain continues to operate normally and user funds and assets are safe.

The new schedule for Enjin Blockchain is:

• Enjin Relaychain:
  December 9, 2025 at 16:30 UTC
  Approximate block: 13,243,426
  
  
• Enjin Matrixchain:
  December 9, 2025 at 16:45 UTC
  Approximate block: 7,732,995

What this means for you:

• The Enjin Blockchain continues to operate normally.
• There is no impact on balances or NFTs.
  No action is required from users or builders at this time.
• Node operators and partners can use the additional time to complete their checks and ensure monitoring and infrastructure are aligned with the new runtimes. Validator operators should be certain that they are at least running the client version v1.5.1.

Thank you for your understanding and for holding us to a high standard. Taking one extra day here helps us deliver a more reliable upgrade for the entire ecosystem.
