durt2 1.3.0

Dart library for interacting with Duniter v2s blockchains. Provides wallet management, transaction signing, Squid GraphQL requests, and more

1.3.0

• Identity-name lookup over the on-chain IdentitiesNames map: DuniterStorageService.getIdentityIndexByName(name) for an exact match, and getIdentityIndexByNameMulti(names) for a batched one (single multiIdentitiesNames RPC, order preserved, result padded to the request length). Both return null for a free name and degrade to null on a WebSocket drop rather than throwing. Lets a client treat the on-chain identity name as authoritative over a self-declared profile name. MockDuniterStorageService gains setReservedName and a nameMultiLookupCount counter so batching can be asserted in tests.
• DuniterStorageService.accountSurvivesAtZero(address): whether an account keeps existing once emptied. True when sufficients > 0, which on Duniter v2s means the account backs an identity (pallet_identity::create_identity calls inc_sufficients on the owner key). Such an account may go below the existential deposit without being reaped, so a client can offer the full balance instead of refusing the amount or burning the change.
• DuniterService.pay takes a keepAlive flag (default true, unchanged behaviour for Ğ1 amounts). false selects the chain's Expendable preservation: transferAllowDeath instead of transferKeepAlive, and transferUd instead of transferUdKeepAlive. This also aligns the two units: UD amounts previously always used transferUd (Expendable) while Ğ1 amounts used transferKeepAlive (Preserve), so the existential-deposit rule silently depended on the display unit.

1.2.1

• Fix macOS biometrics: BiometricService now stores the encrypted PIN in the platform-aware secure storage (file-based on macOS, where the Keychain is not reliably available via Flutter plugins) instead of the raw Keychain plugin. Readable legacy Keychain enrollments are migrated on first use; broken ones simply require re-enrolling. New public API: CryptoUtils.secureRead / secureWrite / secureDelete / secureContainsKey / secureReadAll.

1.2.0

• Contacts sync foundation (Cesium+ pods): CRDT model ContactsSyncState / ContactSyncEntry (per-field last-write-wins, commutative merge, non- destructive removal via isContact, dead-entry GC, forward-compatible unknown fields) and encrypted-blob pod I/O getContacts / saveContacts (cross-preserves the co-hosted certification queue).
