ClientWithFetchAccounts

type ClientWithFetchAccounts = object;

Represents a client that can fetch the content of accounts from their addresses.

Different implementations may fetch accounts differently — for example, by calling the getAccountInfo and/or getMultipleAccounts RPC methods, by reading from a local validator, or by using a locally cached value.

Note that this interface only fetches encoded accounts. Callers that need decoded accounts should decode the returned MaybeEncodedAccount | MaybeEncodedAccounts themselves using the codec of their choice.

If you have a raw Rpc object instead of a client, you can construct a client implementing this interface using the createClientWithFetchAccountsFromRpc helper from @solana/kit.

Example

async function fetchProgramAddresses(client: ClientWithFetchAccounts, addresses: Address[]) {
    const accounts = await client.fetchAccounts(addresses);
    return accounts.filter(account => account.exists).map(account => account.programAddress);
}

Properties

fetchAccounts

fetchAccounts: (addresses, config?) => Promise<MaybeEncodedAccount[]>;

Fetches the encoded content of the accounts at the provided addresses.

The returned array matches the provided addresses in both length and order. Each item is a MaybeEncodedAccount so that missing accounts can be represented whilst keeping track of their address.

Parameters

Returns

Promise<MaybeEncodedAccount[]>

A promise resolving to an array of MaybeEncodedAccount | MaybeEncodedAccounts in the same order as the provided addresses.
