import { AccountsForeignAssetsService } from '../../services/accounts'; import AbstractController from '../AbstractController'; /** * Get foreign asset balance information for an address. * * Paths: * - `address`: The address to query * * Query: * - (Optional)`at`: Block at which to retrieve balance information. Block * identifier, as the block height or block hash. Defaults to most recent block. * - (Optional) `useRcBlock`: When true, treats the `at` parameter as a relay chain block * to find corresponding Asset Hub blocks. Only supported for Asset Hub endpoints. * - (Optional)`foreignAssets`: Comma-separated list of multilocation JSON strings to filter by. * If not provided, all foreign asset balances for the account will be returned. * * `/accounts/:address/foreign-asset-balances` * Returns: * - When using `useRcBlock=true`: An array of response objects, one for each Asset Hub block found * in the specified relay chain block. Returns empty array `[]` if no Asset Hub blocks found. * - When using `useRcBlock=false` or omitted: A single response object. * * Response object structure: * - `at`: Block number and hash at which the call was made. * - `foreignAssets`: An array of `ForeignAssetBalance` objects which have a multilocation attached to them * - `multiLocation`: The multilocation identifier of the foreign asset. * - `balance`: The balance of the foreign asset. * - `isFrozen`: Whether the asset is frozen for non-admin transfers. * - `isSufficient`: Whether a non-zero balance of this asset is a deposit of sufficient * value to account for the state bloat associated with its balance storage. If set to * `true`, then non-zero balances may be stored without a `consumer` reference (and thus * an ED in the Balances pallet or whatever else is used to control user-account state * growth). * - `rcBlockHash`: The relay chain block hash used for the query. Only present when `useRcBlock=true`. * - `rcBlockNumber`: The relay chain block number used for the query. Only present when `useRcBlock=true`. * - `ahTimestamp`: The Asset Hub block timestamp. Only present when `useRcBlock=true`. * * Substrate Reference: * - ForeignAssets Pallet: https://crates.parity.io/pallet_assets/index.html * - `AssetBalance`: https://crates.parity.io/pallet_assets/struct.AssetBalance.html * - XCM Multilocations: https://wiki.polkadot.network/docs/learn-xcm * */ export default class AccountsForeignAssetsController extends AbstractController<AccountsForeignAssetsService> { static controllerName: string; static requiredPallets: string[][]; constructor(api: string); protected initRoutes(): void; private getForeignAssetBalances; }
