Controllers

This package features the following controllers:

• AccountTrackerController keeps a updated list of the accounts in the currently selected keychain which is updated automatically on a schedule or on demand.
• AssetsContractController provides a set of convenience methods that use contracts to retrieve information about tokens, read token balances, and transfer tokens.
• CollectibleDetectionController keeps a periodically updated list of ERC-721 tokens assigned to the currently selected address.
• CollectiblesController tracks ERC-721 and ERC-1155 tokens assigned to the currently selected address, using OpenSea to retrieve token information.
• CurrencyRateController keeps a periodically updated value of the exchange rate from the currently selected "native" currency to another (handling testnet tokens specially).
• TokenBalancesController keeps a periodically updated set of balances for the current set of ERC-20 tokens.
• TokenDetectionController keeps a periodically updated list of ERC-20 tokens assigned to the currently selected address.
• TokenListController uses the MetaSwap API to keep a periodically updated list of known ERC-20 tokens along with their metadata.
• TokenRatesController keeps a periodically updated list of exchange rates for known ERC-20 tokens relative to the currently selected native currency.
• TokensController stores the ERC-20 and ERC-721 tokens, along with their metadata, that are listed in the wallet under the currently selected address on the currently selected chain.
