Subject: Shutter API Keypers (DAppNode) – New Release: v0.1.7

Hello Keypers,

We have released an update for the API DAppNode Keyper: v0.1.7.

The IPFS link can be found here: https://dappnode.github.io/explorer/#/repo/0x8928c414c10d5eeaf2eea30702b3a0c03d52ff6f/0.1.7

This release upgrades the package to Keyper v1.4.0 and includes important fixes and improvements to stability, metrics, database handling, and API behavior. While this release introduces support for event-based decryption conditions, this functionality is not enabled yet. We will first complete additional testing on Chiado and ensure that all Keypers have upgraded before enabling it on Mainnet.

Highlights:

• Upgrade Keyper to v1.4.0
• Add support for event-based decryption conditions via ShutterEventTriggerRegistry (not enabled in this release)

Fixes & Improvements:

• Fix event-based decryption trigger DB migration
• Fix decryption_key API endpoint
• Fix issue where the Keyper could hang under certain conditions
• Fix compatibility with previous eons
• Update handler and middleware to allow no signature on keys messages and skip signature checks for decryption triggers where applicable
• Fix Nethermind WebSocket port issue
• Fix metrics display issues
• Improve metrics restart policy
• Bump staker script to v0.1.2

Action Required:

• Update your DAppNode API Keyper to v0.1.7
• Check your logs and metrics to ensure everything is running as expected
• Report any issues promptly so we can investigate and assist

Important:
Please update to this release as soon as possible. This helps keep your node operational and prepares the network for upcoming features, including event-based decryption, once it is enabled.

Your timely updates and feedback are essential to keeping the Shutter network healthy and reliable.

@blockchainluffy leaving here an update on this release.

The PR is ready and I tested the package under the Mainz DAppNode with the below hash.

Dappnode Package (shutter-api-gnosis.dnp.dappnode.eth) built and uploaded 
DNP name : shutter-api-gnosis.dnp.dappnode.eth
Release hash : /ipfs/QmPZXhsMb6XSL48S3RMT8SCUS1z4Mn8H2u2yPqVD2VXTmH
http://my.dappnode/installer/public/%2Fipfs%2FQmPZXhsMb6XSL48S3RMT8SCUS1z4Mn8H2u2yPqVD2VXTmH

The only thing I noticed so far is that some of the logs are not well formed, see an example here:

2025/12/19 21:56:55.567479 INF [     newblock.go:140] skipping event as not part of keyper set address=0x53E9F13dd7428c233E21B0F2A4CD012F28876903 block-number=43355039 eon=12 identity="#�\b]\x00�VgOPG\x12>�{�\x1d�~@dzK\x1d�>�c����"

Could you please have a look see if this is related to some of the latest fixes, and also do some last tests before we can release it. I also added the communication to send above.

Thank you!

@ylembachar in this log the identity is not well formed as it is converted to string in the wrong way. Not urgent to fix this issue as it will only appear on non keyperset members and does not affect any functionality. Added an issue to fix this in the next release: shutter-network/rolling-shutter#661

[blockchainluffy]

the above build is tested and works as expected
