Split popup/index.js (784 lines) into focused modules:
- shared/state.js: state management, storage persistence
- shared/wallet.js: mnemonic gen, HD derivation, signing
- shared/prices.js: price cache (5min TTL), USD formatting,
value aggregation (address → wallet → total)
- shared/balances.js: ETH + ERC-20 balance cache (60s TTL),
ENS lookup, token contract metadata lookup
- shared/vault.js: unchanged (libsodium encryption)
- shared/tokens.js: unchanged (token list + CoinDesk client)
- popup/index.js: view switching and event wiring only
Token tracking is now app-wide: trackedTokens stored in state,
balances fetched for all tracked tokens across all addresses.
Add Token now calls the real contract to read name/symbol/decimals.
Total portfolio value shown in 2x type on Home screen.
vault.js: Argon2id key derivation + XSalsa20-Poly1305 encryption
via libsodium-wrappers-sumo. No raw crypto primitives.
Wallet creation now requires a password. The mnemonic or private
key is encrypted before storage — only the ciphertext blob
(salt, nonce, ciphertext) is persisted. The plaintext secret
is never stored.
Sending requires the password to decrypt the secret, derive
the signing key, and construct the transaction. Wrong password
is caught and reported.
tokens.js: ~150 ERC-20 tokens ordered by market cap with
getTopTokenSymbols(n) and getTopTokenPrices(n) (errors if n>30).
Price fetching uses CoinDesk CADLI API. Popup now shows USD
values next to ETH balances in wallet list and address detail.
Prices and balances fetched in parallel on popup open.
Makefile, Dockerfile, CI workflow, prettier config, manifests for
Chrome (MV3) and Firefox (MV2), source directory structure, and
minimal test suite. All checks pass.
