Daedalus 11.6.0 Add Recovery for Mithril Sync Damage for Cardano

Se7en Labs don release Daedalus 11.6.0 on October 24, wey introduce automatic way to detect where blockchain data miss, plus better recovery, transaction handling, and app reliability.

The mainnet update dey address damage wey fit remain after partial Mithril synchronization for versions wey older than 11.5.0. Even though the previous release stop new gaps from dey form, Daedalus 11.6.0 fit identify the damage wey already dey and offer recovery procedure without make users dey find the problem by themselves.

Daedalus Dey Detect Existing Mithril Sync Problems

Different from lightweight Cardano wallets, Daedalus dey run full Cardano node for the user computer and e dey keep local copy of the blockchain. This one allow am verify network data by itself, but e also mean say reliable synchronization dey very important.

Mithril dey speed up synchronization through cryptographically verified blockchain snapshots. But earlier implementations of partial synchronization fit leave some sections of the local blockchain incomplete, wey fit stop the node from processing more blocks or continue synchronization.

Daedalus 11.6.0 don bring checks for these conditions. When the app identify say blockchain data miss, e go offer Rebuild blockchain data option instead make users dey investigate the failure by themselves.

The Diagnostics panel now get special Blockchain data section wey dey show detected damage, including the affected slot and time. Users fit copy this information put inside diagnostic reports for technical support.

The rebuild option dey also available direct from Diagnostics, even when dem never detect any damage.

Verified Mithril Recovery Need User Confirmation

The recovery process get extra safeguards wey aim to prevent unnecessary data loss or unexpected synchronization behavior.

Before dem replace blockchain data, Daedalus dey check whether suitable Mithril snapshot dey available and whether the destination folder dey accessible. E still dey verify available storage space when e fit get the required information.

Recovery go start only after clear user confirmation. The operation dey replace local blockchain data but e go preserve the wallet data wey dey the computer.

If recovery fail or dem interrupt am, Daedalus go keep the information wey e need to manage the recovery process. E also no go quietly start full blockchain synchronization from genesis.

Startup monitoring don improve. If cardano-node no write anything for disk for five minutes during startup, users fit choose to restart the node or continue to wait.

Mithril downloads go also show when progress pause because the app dey wait make network connectivity return.

Ledger and Trezor Transaction Fixes Improve Reliability

Beyond blockchain recovery, Daedalus 11.6.0 don resolve several problems wey dey affect transactions and app startup.

The release don restore Send confirmation dialogs and fix transaction submission after approval through Ledger or Trezor hardware wallets.

E also correct issue wey canceling preparation of one hardware-wallet transaction fit interfere with another transaction. Now, transaction approvals go remain tied to the wallets wey originate dem until submission complete.

Additional fixes address Electron startup failures and Windows and macOS packaging issues. Electron don upgrade to version 42.11.14, while the cardano-wallet backend move to v2026-10-07. The underlying cardano-node version remain 11.1.3.

Linux users still fit access the portable .bin installer, although dem don deprecate am in favor of native Debian, RPM, and Arch packages, plus NixOS support.

Se7en Labs dey recommend make all Daedalus users upgrade to version 11.6.0. For installations wey older partial Mithril synchronizations don affect, the release dey provide recovery path using verified snapshot, and replacement of blockchain data still remain under the user control.
