# Tasks: enterprise-react-crypto

**Change ID**: enterprise-react-crypto
**Package**: `@suaveplan/react-crypto`
**Target path**: `react/auth/react-crypto`
**Prerequisite packages on Verdaccio**: `@suaveplan/error`, `@suaveplan/crypto`, `@suaveplan/crypto-browser`, `@suaveplan/react-translate`

## 0. Pre-flight (non-negotiable)

- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.

## 1. Scaffold

- [ ] Create directory tree per proposal layout.
- [ ] Write `package.json` at `0.1.0` with `"sideEffects": false`, exports map.
- [ ] Dependencies: `@suaveplan/error workspace:^`, `@suaveplan/crypto workspace:^`, `@suaveplan/crypto-browser workspace:^`, `@suaveplan/react-translate workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `tslib catalog:build`.
- [ ] Write `tsconfig.json`, `vitest.config.ts`, scripts.

---

## 2. Error codes and types

- [ ] Define `WalletError` extending `SuaveplanError`; codes: `WALLET_CONNECT_FAILED`, `WALLET_NOT_CONNECTED`, `WALLET_SIGN_FAILED`, `WALLET_NETWORK_ERROR`.
- [ ] Define `WalletProvider` interface (injectable): `connect()`, `disconnect()`, `getAddress()`, `getBalance()`, `getNetwork()`, `switchNetwork(chainId)`, `sendTransaction(tx)`, `signMessage(msg)`.
- [ ] Define `Network`, `TokenBalance`, `Transaction`, `TransactionDirection`, `TransactionStatus`, `WalletInfo`, `WalletStatus`.
- [ ] Write Zod schemas for `Network`, `Transaction`.

---

## 3. WalletProvider adapters

- [ ] `MetaMaskAdapter` — wraps `window.ethereum` EIP-1193 provider.
- [ ] `WalletConnectAdapter` — wraps injected `WalletConnectProvider`.
- [ ] Both implement `WalletProvider` interface.
- [ ] Write tests using DI (inject mock `window.ethereum`) + md.

---

## 4. EVM utils

- [ ] `explorerUrl(network, txHash)`, `formatAddress(addr, length?)`, `formatBalance(wei, decimals?)`, `isValidEvmAddress(addr): boolean`, `networkDisplayName(chainId): string`.
- [ ] Write `evm-utils.test.ts` (all functions, edge cases) + md.

---

## 5. Hook — `useWallet`

- [ ] Accepts `provider: WalletProvider` + `autoConnect?: boolean`.
- [ ] State: `address`, `balance`, `network`, `status: WalletStatus`, `transactions`.
- [ ] `connect()` — calls `provider.connect()`; throws `WalletError(WALLET_CONNECT_FAILED)` on failure. OTel `wallet.connect` span.
- [ ] `disconnect()` — calls `provider.disconnect()`.
- [ ] `switchNetwork(chainId)` — calls `provider.switchNetwork()`; throws `WalletError(WALLET_NETWORK_ERROR)` on failure.
- [ ] `sendTransaction(tx)` — throws `WalletError(WALLET_NOT_CONNECTED)` if not connected. OTel `wallet.send_transaction` span.
- [ ] `signMessage(msg)` — throws `WalletError(WALLET_SIGN_FAILED)` on error. OTel `wallet.sign` span.
- [ ] Write `use-wallet.test.ts` (≤500 lines): connect, disconnect, autoConnect, switchNetwork, sendTransaction, signMessage, all error cases. DI injected mock `WalletProvider`. `{ timeout: 10000 }`.
- [ ] Write `use-wallet.stories.tsx`: connected, disconnected, loading, wrong-network, playground.
- [ ] Write `use-wallet.md`.

---

## 6. Components

### WalletConnect

- [ ] Connect/disconnect button; shows address when connected.
- [ ] Write test, stories, md.

### AddressDisplay

- [ ] Shortened address with copy-to-clipboard. Write test, stories, md.

### BalanceDisplay

- [ ] Token balance with symbol. Write test, stories, md.

### TransactionList

- [ ] Paginated list of `Transaction` items with status badges, explorer links. Write test, stories, md.

---

## 7. E2E

- [ ] `e2e/wallet.spec.ts` — Playwright with injected mock provider:
  - Click "Connect" → address displayed.
  - Call `signMessage('hello')` → mock returns signature, displayed.

---

## 8. Verify and publish

- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/react-crypto` — green.
- [ ] `bunx turbo test:coverage --filter=@suaveplan/react-crypto` — 100%.
- [ ] `bun scripts/publish.ts --package @suaveplan/react-crypto`.
- [ ] Archive change folder.
