Description

Registers the robinhood currency plugin so users can create a Robinhood Chain wallet. Robinhood Chain is an Arbitrum L2 (EVM chain 4663) that uses ETH for gas.

Asana: https://app.asana.com/1/9976422036640/project/1213843652804305/task/1217382370104887

Five files, matching the opbnb and monad registrations: corePlugins.ts, envConfig.ts, WalletAndCurrencyConstants.ts, and the two locale files.

WalletAndCurrencyConstants.ts carries two list entries, not one. Beyond WALLET_TYPE_ORDER and the SPECIAL_CURRENCY_INFO block, robinhood also goes in CURRENCY_SETTINGS_KEYS, which WalletSettingsModal reads to decide whether to show the Asset Settings row and which AssetSettingsScene maps to build its list. Every peer EVM L2 is in it. Bugbot caught the omission; the rest of the GUI's hardcoded pluginId lists were checked and correctly exclude this chain, since they are ramp and payment-protocol asset maps for providers that do not support it.

showChainIcon: true is the one entry worth a look. The native asset is ETH, so without the chain badge a Robinhood Chain wallet is indistinguishable from an Ethereum mainnet wallet in the wallet list. arbitrum and base set it for the same reason.

The wallet name string is "My Robinhood Chain" rather than "My Robinhood", since the shorter form reads as a brokerage account.

Testing. Full jest suite, snapshots and eslint pass. Driven on the iOS simulator against EdgeApp/edge-currency-accountbased#1087 linked in: searching "Robinhood" in Choose Wallets to Add lists the chain, creating gives "My Robinhood Chain" on a wallet scene titled "Robinhood Chain Network", and importing a seed with real on-chain history renders its live balance. After the CURRENCY_SETTINGS_KEYS fix, re-driven to confirm the wallet's Asset Settings row renders and "Robinhood Chain" appears in the Asset Settings list between Ravencoin and Rootstock. Screenshots are attached in comments below.

One search behavior to know when testing: filterWalletCreateItemListBySearchText requires every whitespace-separated term to prefix-match a field, so typing the full "Robinhood Chain" returns nothing while "Robinhood" matches.

Follow-ups, neither blocking:

• ROBINHOOD_INIT needs adding to the deployed env.json, or asCorePluginInit returns false and the plugin ships disabled.
• Currency icons at content.edge.app/currencyIconsV3/robinhood/ (robinhood.png, chain_robinhood.png) do not exist yet, so the wallet renders a text placeholder in the app.
