 ## Summary
 
-Promote 4.2.0 from 4.2.0‑beta.1 with no functional changes. Stability verified across core flows and ecosystems.
+Promote 4.2.0 from 4.2.0‑beta.1 with no functional changes. Stability already verified across core flows and ecosystems during beta; this release locks the artifacts, tags the repo, and rolls out broadly.
 
 ## Changes Since 4.2.0‑beta.1
 
 - No functional changes; version bump only
 - Continue to monitor crash/ANR metrics and session health
 
+## Pre‑Release Steps
+
+1. Versioning & docs
+   - Update `versionName`/`versionCode` to `4.2.0` in `build.gradle`.
+   - Ensure `CHANGELOG.md` and this file reflect the final scope (reuse beta highlights).
+2. Alignment & toolchain validation
+   - `./gradlew printPolkadotSdkAlignment` — confirm URLs and optional shared_features pin.
+   - `./gradlew detektAll`
+   - `./gradlew runTest`
+   - `./gradlew :app:lint`
+   - `./gradlew postMergeVerify`
+3. Smoke tests (reuse beta matrix)
+   - Polkadot/Kusama transfers, staking read paths.
+   - Ethereum/Polygon/BSC send + Reown signing.
+   - TON send/receive; Coinbase provider fetch; remote asset sync refresh.
+4. Release artifacts
+   - `./gradlew :app:assembleRelease`
+   - Archive the generated AAB/APK plus `mapping.txt` and detekt/test reports.
+
+## Release Packaging & Submission
+
+1. Tag the repo after verifying artifacts: `git tag -s 4.2.0 -m "fearless-Android 4.2.0" && git push origin 4.2.0`.
+2. Upload the release bundle to Google Play (Production track, staged rollout) using the same localized notes as beta.
+3. Attach internal links (Confluence/Jira) to `docs/releases/4.2.0-beta.md` and QA sign-off.
+4. Announce code freeze lifted once Play shows the build in review.
+
 ## Rollout Plan
 
-- Staged rollout: 10% → 25% → 50% → 100%
-- Halt criteria: crash‑free drop > 0.5% or new P0/P1 defects in core flows
+- Day 0: Start at 10% of production. Monitor crash-free users, ANR rate, WalletConnect errors, TON RPC failures.
+- Day 2 (≥24h healthy): Increase to 25%. Validate Coinbase provider metrics and EVM signing telemetry.
+- Day 4: Increase to 50% if crash-free ≥99.5% and no new P0/P1 issues.
+- Day 6+: Go to 100% once KPIs remain stable; otherwise hold rollout and investigate.
+- Communication: Post rollout status in release channel after each increment; include key metrics snapshot.
+
+## Monitoring & Halt Criteria
+
+- Halt/rollback if crash-free sessions drop by >0.5%, ANR rate increases >0.2%, or any new P0/P1 defect in onboarding, send, staking, TON, or Reown flows.
+- If halted, pause the staged rollout in Play, gather logs/Crashlytics links, and triage before resuming.
+- Keep Jenkins/GitHub CI green for hotfix readiness.
 
 ## Store Notes (Play)
 
-- Use the same release notes as the beta
-- Attach links to docs/releases/4.2.0-beta.md for internal reference
+- Use the same release notes as the beta (TON public features, Coinbase provider, Reown migration, toolchain upgrades, stability fixes).
+- Reference this doc plus `docs/releases/4.2.0-beta.md` in internal QA submissions.
 
 ## Post‑Release
 
-- Tag: `git tag -s 4.2.0 -m "fearless-Android 4.2.0" && git push origin 4.2.0`
-- Create `4.2.x` patch branch if needed
-- Update `docs/status.md` and `docs/roadmap.md` to reflect current state
+- Keep monitoring metrics for 7 days; escalate regressions to roadmap/docs.
+- Create `4.2.x` patch branch if hotfix required.
+- Update `docs/status.md` and `docs/roadmap.md` once rollout completes to capture live health snapshot.
