Out of the box the wallet sent the user's addresses to Blockscout for history
and token lookups, and each recipient to Etherscan for its label. Two settings,
"Use Blockscout" and "Check recipients on Etherscan", now gate those requests
where they are made. Both are off in a new profile and offered unticked on
Welcome and in Settings. While one is off, the screens that relied on it say so
in a plain line naming the setting; after either changes in Settings, Back
draws the screen it lands on again. README and the user guide say what is
contacted by default and what each setting adds.

networks.js gives each network a nativeCurrency (ETH, SepoliaETH) and nothing
read it: every screen wrote ETH. The wallet's balances and the Send and
confirmation screens now use the active network's. A transaction's figures use
the network its chain id names, through nativeCurrencyByChainId(): the
approval value and fee, the wait, success and error screens, history entries,
the detail screen and the fee-limit refusal, so a site switching networks
cannot make one read as another network's coin. The "ETH" that selectedToken
and txInfo.token hold is the native token's id and is unchanged. A token
reporting any network's nativeCurrency is a spoof, and the detail screen calls
an entry a token transfer when it has a token contract.

Five defects, one of which destroyed every wallet, came from src/background reading and writing the module-level state singleton the MV3 worker never populates, which silently served DEFAULT_STATE. Each point fix created the next defect. The background now has its own per-call getState() and a queued read-modify-write updateState(); the singleton is unreachable from it, and an unpopulated read throws instead of serving defaults.
The prohibition is enforced by the build, not by review: build.js asserts over esbuild's own metafile that no forbidden module is an input of a background bundle, so every specifier syntax esbuild resolves is covered, and both halves of the table are checked for rot -- a stale key, a stale module, an empty list, or an unlisted entry point under src/background/ all fail the build. The ESLint rule remains as fast local feedback and reads the same shared table. Known bounds are documented where the table lives.
Also closes#320: getProvider() now requires a validated network id, so a cold worker no longer prepares a non-mainnet dApp transaction for mainnet and gets refused by the wallet's own verifier. backgroundRefresh() no longer mutates address objects across a network round trip, the broadcast path takes its endpoint and chain id from one snapshot, and eight test storage stubs now structured-clone on get as the real chrome.storage.local does.

Seven bundled tokens were filtered as spoofs at their own address, so a user
holding FRAX, TON, REUSD, EURE, MSUSD, MUSD or JPYC could not see or spend the
one the wallet happened not to pick.
The known-symbol table is derived from the bundled token list, first-wins in
market-cap order, so a symbol that appears twice silently condemned its second
contract. Both are real tokens from the same fetch and neither is stale --
three pairs are one issuer's old and new contract, four are unrelated issuers
sharing a ticker. Picking a winner would have been guessing, and dropping the
ambiguous symbols would have ended spoof filtering for those tickers entirely.
The table now maps a symbol to the set of addresses that legitimately bear it.
A contract outside the set is still a spoof, so the check is not weakened: a
third contract bearing any of the seven shared tickers is refused, and that is
tested. The filter decides what is fake, not what is worth holding, so a legacy
contract stays in the set -- it still holds real balances.
A test walks the whole bundled list asserting no token is filtered at its own
address, which is the guard whose absence let this ship.
47 tests over src/shared/transactions.js: both real address-poisoning attacks
as fixtures, each of the four filters on and off, threshold boundaries, no
false positives, and the per-address merge/dedup path. No source file changed.
