Out of the box the wallet sent the user's addresses to Blockscout and each recipient's address to Etherscan. Two settings, "Use Blockscout" and "Check recipients on Etherscan", now gate every request that sends the user's data to those services. Both start off and are offered unticked on Welcome and in Settings. Each request reads its setting from storage before it asks. An answer that lands after the setting went off is dropped. While a setting is off, the screens that rely on it say so. ENS lookups ask only the RPC endpoint, so a name resolved off-chain does not resolve. RULES.md's External Communication item is now out of date. Its new wording will be proposed on #211 once this lands. Model: opus-5-5 (implementation, summary); fable-5-1 (prose)

// The popup's network switch.
|
|
//
|
|
// A network switch reaches the popup's `state` in one of two ways:
|
|
//
|
|
// - onChainSwitch() below makes the switch the user picks in Settings, with
|
|
// applyChainSwitchFields() (chainSwitchFields.js).
|
|
// - followStoredSettings() in src/popup/index.js takes a switch the background
|
|
// or another popup page saved, from the stored record, with
|
|
// takeStoredNetwork() (state.js), which copies it with
|
|
// copyChainSwitchFields() (chainSwitchFields.js).
|
|
//
|
|
// Both change `state` inside a save, holding the lock, and both reset the
|
|
// popup's own caches through clearPopupCaches(), so a reset added there
|
|
// reaches both. A field applyChainSwitchFields() sets has to be copied by
|
|
// copyChainSwitchFields() too.
|
|
//
|
|
// Adding a new chain (e.g. ETC) requires only a new entry in
|
|
// networks.js — no per-caller wiring is needed.
|
|
//
|
|
// The background does NOT come through here: this function mutates the
|
|
// module-level `state` singleton, which the MV3 service worker never
|
|
// populates, and a background switch performed on it wrote DEFAULT_STATE over
|
|
// the user's whole profile
|
|
// (https://git.eeqj.de/sneak/AutistMask/issues/316). The field mutations
|
|
// themselves live in chainSwitchFields.js, which takes the record to mutate as
|
|
// an argument; src/background/state.js applies them inside a read-modify-write
|
|
// against storage, and the singleton is not reachable from the background
|
|
// bundle at all (enforced by the ESLint rule in eslint.config.js).
