Full support for Polkadot SDK release: polkadot-stable2503

Why: Align the wallet with the latest stable Polkadot SDK, ensuring type/metadata compatibility and correct decoding/encoding across chains.

Scope: Substrate runtime alignment across Polkadot/Kusama/Westend/AssetHub and major parachains used by the app (per chains.json).

Acceptance criteria:

  • App runs without SCALE decode errors on target chains.
  • Balances, transfers, fees, and staking screens load and execute extrinsics successfully on Polkadot and Kusama.
  • Chain sync (ChainRegistry) stable: connections establish, runtime providers load, subscriptions update on version bumps.
  • No regressions in unit tests; detekt/lint green.
  • If APIs changed (e.g., extrinsic names/signatures), code updated or guarded by capability checks; createPool/rename items validated.

Suggested steps:

  1. Registry overrides: In local.properties, set
    • TYPES_URL_OVERRIDE=https://<your>/all_chains_types_android.json (stable2503-aligned)
    • DEFAULT_V13_TYPES_URL_OVERRIDE=https://<your>/default_v13_types.json
    • CHAINS_URL_OVERRIDE=https://<your>/chains.json (validated against stable2503)
  2. Utils integration (remote source): The build fetches soramitsu/fearless-utils-Android via sourceControl and compiles it from source. Ensure NDK 25.2.9519653 + Rust toolchain with Android targets are installed (see README).
  3. Optional: pin shared_features via SHARED_FEATURES_VERSION_OVERRIDE=1.x.y if required by the SDK combo.
  4. Build + checks:
    • ./gradlew detektAll runTest :app:lint
    • ./gradlew :app:assembleDebug
  5. Runtime smoke tests (manual):
    • Verify ChainRegistry establishes connections and loads metadata (logcat).
    • Wallet → Balances shows assets and fiat values.
    • Send: compute fee and submit a small transfer on Westend/Kusama dev if available.
    • Staking: validators/nominators decode, no crashes.
  6. Address API deltas:
    • Update runtime-extrinsic assumptions and storage paths; add capability checks as needed.
  7. Update defaults (optional): If stable2503 becomes default, update runtime/build.gradle and docs with new registry URLs.
  8. Document: Add the exact registry URLs used to docs/status.md and a short note on verification results.

Bugfix backlog (from QA CSV):

  • TON: 'address' in HEX form — approval window missing; Wrong address format (code 1)
  • TON: user declined the transaction — error surfaced; SDK code 300
  • TON: 'validUntil' expired during confirmation — “Transaction has expired” (code 1)
  • TON: 'address' in non-bounceable form — processed with bounce=false; verify UI/SDK handling

Verification matrix (execute manually or script):

  • Polkadot: balances load, transfer fee computed, send succeeds on test account.
  • Kusama: same as above; staking validator list loads.
  • AssetHub: asset enumeration works; transfers to another account OK.
  • Westend: basic transfer path for low-risk checks.

Build & Play Compliance

  • Gradle/AGP update: bump Gradle wrapper and Android Gradle Plugin to the latest stable release; remove deprecations (e.g., use url = uri(...), namespace = '…'). Verify builds with JDK 21 locally and in CI.
  • Google Play 16KB page size: migrate native libraries (e.g., sr25519) to NDK r28+ (16 KB pages by default). Validate with readelf -l and address Play Console checks. Keep packaging compliant (uncompressed native libs or required flags).
