+# Publishing
+
+> **Publishing is CI-only. Never publish or stage from a local machine.** Do not run `changeset version`,
+> `changeset publish`, `npm publish`, `npm stage publish`, `pnpm publish`, or the internal `ci:stage-release`
+> script yourself. A local release bypasses the signed release commit and npm OIDC trusted publishing. Your job as
+> a contributor is to land a changeset (see "Day-to-day") and let CI prepare the release; an npm maintainer
+> performs the final 2FA approval.
+
+Releases are driven by [changesets](https://github.com/changesets/changesets). Packages are versioned
+independently (there is no `fixed` group); `updateInternalDependencies: patch` bumps dependents when a workspace
+dependency is released.
+
+## Day-to-day: add a changeset
+
+Every PR that changes files inside a published package must include a changeset. From the repo root:
+
+```bash
+pnpm exec changeset
+```
+
+Pick the packages and bump type and write a user-facing changelog entry. For changes with no consumer impact
+(internal refactors, chores), record an empty changeset instead:
+
+```bash
+pnpm exec changeset add --empty
+```
+
+The `Changeset check` CI job fails a PR that touches a package without one.
+
+## Release flow (automated)
+
+1. Merging PRs with changesets into `master` triggers the `Release` workflow
+   (`.github/workflows/npm-release-trigger.yml`), which opens or updates a **`changesets: Release / Deploy`** PR.
+   That PR applies the pending changesets, bumps package versions, and updates each `CHANGELOG.md`.
+2. Review and merge that Release PR.
+3. On merge, the same workflow uses npm `11.15.0` and runs the release gates (`ci:release-gates`: build,
+   typecheck, lint, release script tests, and the full test suite against an anvil fork) before the release bot
+   token is minted, so build and test code never sees it. It then packs every publishable package whose version
+   is not yet on npm with pnpm, which rewrites `workspace:` ranges to real versions, and fails if any `workspace:`
+   range remains.
+4. The workflow sends the tarballs to `npm stage publish` under the `latest` dist-tag via **OIDC trusted
+   publishing** (no `NPM_TOKEN`). After each package stages, Changesets pushes its package tag (e.g.
+   `@0xsequence/wallet-core@3.0.14`) and creates a GitHub Release from its `CHANGELOG.md` entry.
+5. An npm maintainer inspects and approves every staged package with 2FA. **Approve in the order listed in the
+   workflow run summary** (dependencies first, e.g. `wallet-primitives` before `wallet-core` before `wallet-wdk`)
+   so each approved package's dependencies are already installable.
+
+Version-bump commits are signed by GitHub's GPG key (`commitMode: github-api`). The package tags and GitHub
+Releases record that CI staged the exact release artifacts; they do not mean npm approval has finished.
+
+### Approve a staged release
+
+On npmjs.com, open each package's **Staged Packages** tab and approve, or from the CLI:
+
+```bash
+npm stage list @0xsequence/wallet-core
+npm stage view <stage-id>
+npm stage approve <stage-id> # prompts for 2FA
+```
+
+If one tarball stages and a later tarball fails, do not merge another release. The workflow creates the
+successful packages' tags before failing; after fixing the cause, rerun that workflow and the release helper will
+skip the tagged stages. If staging succeeded but its package tag was not created, reject that partial stage with
+`npm stage reject <stage-id>` before retrying because staging reserves the package version.
+
+## Prerelease / snapshot builds
+
+To prepare a throwaway prerelease under a non-`latest` npm dist-tag, manually dispatch the **Release** workflow —
+this is still CI, not a local release:
+
+1. GitHub → **Actions** → **Release** → **Run workflow** (on `master` or a feature branch).
+2. Set the **`snapshot_tag`** input to a non-semver dist-tag (e.g. `canary`, `pre-3.0.14`).
+
+The workflow versions **every** publishable package as `0.0.0-<tag>-<timestamp>` on the runner (never committed),
+so snapshot packages only depend on each other, then packs and stages them. The snapshot path skips git tags and
+GitHub Releases, so **`snapshot_tag` must be a lowercase, non-version tag other than `latest` or `v2-legacy`**. An
+npm maintainer must approve the stages before consumers can install them with
+`pnpm add @0xsequence/wallet-wdk@<tag>`.
+
+## v2 (`v2-legacy`)
+
+The `v2` branch has its own `npm-release-trigger.yml` with the same flow, except it stages under the
+**`v2-legacy`** dist-tag so v2 releases never move `latest` (which belongs to v3). The workflow file name is the
+same on both branches, so one trusted publisher configuration per package covers both.
+
+## One-time setup (admins)
+
+- **npm trusted publishers:** run `./scripts/configure-npm-trust.sh` (runs npm 11.15.0 via `npx`; needs an npm login with
+  publish rights, and 2FA). It registers `0xsequence/sequence.js` + `npm-release-trigger.yml` as a **stage-only**
+  trusted publisher (`--allow-stage-publish`, no `--allow-publish`) for every package on `master` and `v2`, so CI
+  can stage but never publish directly. Afterwards, set each package's publishing access to "Require two-factor
+  authentication and disallow tokens" and revoke old automation tokens.
+- **GitHub:** the release workflow authenticates as the **0xsequence Changesets Release Bot** GitHub App, owned
+  by the `0xsequence` org (Polygon's `0xpolygon-changesets-release-bot` is private to `0xPolygon` and cannot be
+  installed here). The app needs repository permissions **Contents: read & write** and **Pull requests: read &
+  write**, no webhook, and is installed on this repository only. Its App ID and a private key are stored as the
+  repository secrets `CHANGESET_RELEASE_BOT_APP_ID` and `CHANGESET_RELEASE_BOT_APP_PRIVATE_KEY`. The app (not the
+  default `GITHUB_TOKEN`) is required so the release PR triggers CI and its commits are signed. To rotate the key,
+  generate a new one in the app settings, update the secret, then delete the old key.
