v1.4.0 — Nervos DAO Protocol Integration

What's New

Nervos DAO Integration

• Deposit to DAO: Lock CKB in the Nervos DAO to earn compensation (minimum 102 CKB)
• Withdraw from DAO (Phase 1): Initiate withdrawal, converting deposit cell to withdrawing cell
• Unlock from DAO (Phase 2): Claim deposited CKB + accumulated compensation after 180-epoch lock period
• Compensation tracking: Real-time display of accrued DAO compensation per deposit
• Cycle progress: Visual progress bar showing position within current 180-epoch lock cycle with phase indicators (Normal → Suggested → Ending)
• Lock countdown: Hours remaining until unlock displayed for locked deposits
• 7-state DAO FSM: Full deposit lifecycle tracking (Depositing → Deposited → Withdrawing → Locked → Unlockable → Unlocking → Completed)
• Auth-gated deposits: Biometric or PIN authentication required before DAO deposits

JNI DAO Utilities (Rust)

• nativeExtractDaoFields: Parse DAO header into C/AR/S/U fields
• nativeCalculateMaxWithdraw: Compute deposit + compensation using RFC-0023 formula
• nativeCalculateUnlockEpoch: Calculate phase 2 unlock epoch with 180-epoch boundary rounding

UI

• New DAO tab with deposit list, deposit bottom sheet, and compensation progress bars
• DAO transaction badges in activity feed (DAO Deposit, DAO Withdraw, DAO Unlock)
• Neuron-style deposit cards with status, compensation, and lock info
• Learn CKB link added to website navbar and footer

Testing

• 9 new test files covering DAO models, constants, direction detection, transaction building, ViewModel state, and formatting

Bug Fixes & Hardening

• Paginated cell/transaction fetching for large deposit sets
• Epoch fraction validation (length > 0, index < length)
• Max withdraw return value guards preventing silent corruption
• Deposit block hash preservation on header fetch failure
• Clipboard auto-clear after 30s when copying private key
