🔧 Hardware Wallets & Transaction Ordering

Hardware wallets require a specific ordering of transaction body fields; the current CLI does not enforce this.
A workaround using cardano-hw-cli (by Vacuum Labs) is available to transform transactions into the expected format.
This is not considered urgent due to the availability and ease of the workaround.
The existing issue will be relabeled as "hardware wallet support" for clarity.
Further investigation may be needed to ensure no other compatibility issues exist beyond field ordering.

The script for witnessing API refactor is nearing completion.
This refactor is a prerequisite for enabling a modular structure in cardano-api.
Once complete, it will support more haddocks and better developer documentation.

The team is evaluating whether to implement gRPC internally.
A community proposal funded via Catalyst is already working on this.
Current focus is on identifying real user needs rather than choosing a solution too early.
JSON-RPC + WebSocket is also being used in the ecosystem.

Work on CLI output schemas is temporarily paused due to planning tasks.
It remains a priority and is actively being requested (e.g., by the Blueprints project).
Work will resume after the current planning cycle.

A local Cardano testnet launcher tool is approaching its v1 release.
It allows users to spin up a testnet with default mainnet parameters (faster epochs/slots).
Aimed at DApp developers, educators, and testers.
Tool will be released with documentation and tutorials.
Feedback will guide ongoing development and maintenance.

Meetings will shift from bi-weekly to monthly going forward.
This change is expected to bring:
- More substance to each meeting.
- Increased participation.
Calendars and invites will be updated accordingly.
