Midnight Crypto Airdrop: How to Fix Lace Wallet Sync Errors
The Midnight Glacier Drop snapshot locked in on June 10, 2025, capturing eligible self-custody balances above approximately $100 equivalent across ADA, BTC, ETH, SOL, XRP, AVAX, BNB, and BAT.

For holders who qualified, the 60-day claim window opened with substantial operational friction: Lace Wallet sync indicators freezing at 0% or 50%, Ledger hardware wallets rejecting the 251-byte CIP-8 message that exceeds the 31-byte native signing limit, and T-DUST faucet requests returning "Request failed" errors when users pasted standard Cardano addresses. These aren't edge cases - they're the modal failure modes for first-time claimers working through an unfamiliar Midnight network stack.
The resolution paths exist. They're not elegant, but they're deterministic, and execution risk on a free retroactive token allocation shouldn't be the reason an allocation goes unclaimed.
Decoding the 0% and 50% Sync Freeze in Lace Wallet
The Lace extension manages Midnight network connectivity through an indexer that pulls multi-address balance data from the preview testnet. When this indexer handshake stalls - widely reported between December 2025 and February 2026 - the UI freezes at either 0% (initial discovery phase) or 50% (mid-sync balance aggregation). The wallet isn't broken; the synchronization pipeline is.
The first corrective action is a manual re-sync trigger:
1. Open Lace and navigate to Settings (gear icon, typically upper-right).
2. Select Wallet Sync from the settings menu.
3. Activate the multi-address balance discovery option to force a fresh indexer pull.
If the re-sync fails or returns inconsistent state, the deeper fallback is a seed phrase restoration inside an updated Lace extension. This reseats the wallet's connection to the indexer without affecting on-chain balances - your ADA and any future Midnight allocations remain secure regardless of what the sync indicator reports. The 0% and 50% states are presentation-layer artifacts, not custody failures. Balances are not lost when the UI stalls.
The sync indicator is an indexer health proxy, not a balance audit. A frozen UI does not imply stranded assets.
For users running multiple browser profiles or extensions competing with the indexer endpoint, isolating Lace to a clean Chrome or Firefox profile - with no other wallet extensions active - resolves a non-trivial share of phantom sync stalls. Browser memory pressure is a frequent silent contributor; closing other dApps that maintain WebSocket connections to competing chains typically clears the queue.
Overcoming Ledger CIP-8 Signing Limits for Glacier Drop
The Glacier Drop payload measures 251 bytes. Cardano's CIP-8 message signing standard, which Ledger devices implement natively, caps individual message signatures at 31 bytes. This mismatch is the root cause of signing failures reported across the Cardano Forum and community channels throughout August 2025, with the underlying constraint clarified by Charles Hoskinson on August 5, 2025.
| Parameter | Value | Operational Implication |
|---|---|---|
| Glacier Drop payload size | 251 bytes | Exceeds Ledger native signing capacity |
| CIP-8 Ledger message limit | 31 bytes | Firmware-level constraint, not configurable |
| Workaround path | Software wallet signing or transaction-metadata workaround | Bypasses the 31-byte cap |
For Ledger users, three viable paths exist:
- Switch to a software signing wallet (Yoroi, Eternl, or Lace hot wallet mode) for the Glacier Drop signature specifically. This is the most reliable path; community verification is high and the workaround has been live since the August 11, 2025 wallet update guide.
- Transaction metadata workaround: Some Ledger firmware versions accept larger payloads when signed as transaction metadata rather than as a standalone CIP-8 message. This path is version-dependent and not universally available - test with a non-claim transaction first.
- Wait for vendor firmware updates: Whether all hardware wallet vendors - notably Trezor - have issued native firmware updates for 251-byte CIP-8 signing without transaction-metadata workarounds remains unclear.
The Ledger path is the highest-friction segment of the claim flow. For material allocations held on a Ledger where workaround testing isn't feasible, the default is a verified software wallet for the signature itself. Cold storage guarantees aren't compromised by signing through a hot wallet bound to the same seed - the keys remain secured; only the signature generation step migrates temporarily.
Correcting Midnight T-DUST Faucet Address Mismatches
The Midnight T-DUST faucet distributes testnet tokens that enable contract deployment and test transaction execution before mainnet claim. The faucet does not accept Cardano addresses. Users pasting an addr_test1... string into the faucet request form receive a generic "Request failed" error, with no clarifying detail in the response payload - a UX failure that drives most of the false-negative troubleshooting reports on DEV Community and similar forums.
The correct address to paste is the Midnight unshielded wallet address - a distinct string that Lace exposes through its dedicated Midnight tab, not the standard Cardano receive address. The unshielded address begins with the Midnight network format and is bound to the same seed phrase but represents a separate derivation path within the Midnight protocol's address space.
Resolution procedure:
1. Open Lace and switch to the Midnight tab (not the Cardano tab).
2. Locate the unshielded address field - Lace displays this with a copy-to-clipboard control.
3. Paste this address into the T-DUST faucet form, not your Cardano address.
4. Confirm the faucet returns a transaction hash rather than the "Request failed" error.
If the faucet still returns an error after a verified Midnight address paste, the issue is likely indexer-side throttling rather than address format. Wait 10-15 minutes and retry; the rate-limit window on the testnet indexer is shorter than typical mainnet infrastructure but not instantaneous.
Testnet faucet failures look like wallet failures. They almost never are.
Managing Internal Sub-Wallet Sync for Contract Deployment
Lace partitions Midnight wallet state into three internally managed sub-wallets: shielded, unshielded, and dust/fee components. These sub-wallets sync independently against the indexer, and partial sync state is the dominant cause of contract deployment failures - specifically the balanceUnboundTransaction call returning without execution.
The operational rule: all three sub-wallets must report complete sync before any contract interaction. A 100% sync on the parent wallet with one sub-wallet still indexing produces silent transaction failures, not error messages. The transaction broadcasts, the indexer acknowledges receipt, and the contract call dies in the mempool without surfacing a failure code. This is the kind of failure mode that compounds operational drag because the user has no clear signal that anything went wrong - they simply see no on-chain result.
The verification sequence:
- Open Lace settings and inspect each sub-wallet's sync status individually rather than relying on the aggregate indicator.
- If any sub-wallet reports below 100%, force a re-sync through Settings > Wallet Sync.
- Confirm all three read 100% before initiating any
balanceUnboundTransactionor equivalent contract deployment call.
This is a quiet operational drag - the kind of failure mode that doesn't surface in documentation but accounts for the majority of "I followed the steps and nothing happened" reports in community threads from late 2025 through early 2026.
Alternative Wallet Workarounds for Successful Token Claims
When Lace fails to detect or sign transactions during the Glacier Drop claim window, the fallback tier is community-verified alternative light wallets: Yoroi and Eternl are the two most reliable options. Both handle the CIP-8 signing workaround natively and expose the Midnight unshielded address format without the multi-sub-wallet synchronization complexity that complicates Lace's UX.
The migration follows standard Cardano wallet conventions: importing a seed phrase into Yoroi or Eternl surfaces the same address derivations, so existing Midnight allocations remain visible and accessible. The tradeoff is feature surface - Yoroi and Eternl expose the Glacier Drop claim flow but lack Lace's deeper contract deployment tooling. For claim execution specifically, they're often the superior path; for ongoing Midnight network interaction after the claim settles, Lace remains the primary client.
The decision matrix:
| Scenario | Recommended Wallet |
|---|---|
| Ledger + Glacier Drop claim | Yoroi or Eternl (software signing workaround) |
| Hot wallet + claim + testnet contracts | Lace (full feature surface) |
| Stuck sync on Lace, deadline imminent | Switch to Yoroi or Eternl immediately |
| Ongoing mainnet Midnight interaction | Lace (after sync issues resolved) |
Operational Posture for the Remainder of the Claim Window
The Glacier Drop claim window is 60 days. For users who qualified at the June 10, 2025 snapshot, the window is finite and the operational cost of missing the claim is the full allocation - there's no partial credit mechanism, no late-claim grace period. The technical friction documented above is real but bounded; every failure mode described has a deterministic resolution path.
Three execution principles for the remaining window:
- Don't refresh indefinitely. When the sync indicator stalls, walk away for 15-30 minutes rather than hammering the indexer. If waiting through a stalled sync feels like it's eating productive time, redirect that attention toward something physical - a short mobility routine or quick bodyweight session does more for operational clarity than another refresh cycle.
- Default to software wallets for the signature itself when Ledger signing fails. The cold storage guarantees aren't compromised by signing through a hot wallet bound to the same seed; you're isolating the failure mode, not weakening custody.
- Verify all three sub-wallet sync states before any contract deployment call. The failure mode is silent, not loud, and silent failures are the most expensive in time terms.
The Midnight network remains in preview testnet for most users, and indexer infrastructure stability will improve as mainnet approaches. Today's sync freezes are operational drag, not protocol failure. The allocation is worth capturing - provided the execution friction doesn't compound into missed deadlines. Treat the claim flow like any other operational workflow: identify the failure modes, know the resolution paths, and execute without emotion. The 60-day window is generous, but it is not unlimited, and retroactive allocations don't extend for late claimers.
