createClientWithInterfacesFromRpc

function createClientWithInterfacesFromRpc<TRpc>(
    rpc,
): ClientInterfacesFromRpc<TRpc>;

Creates a client from a raw Rpc object, filling in whichever client interfaces the RPC supports.

The returned object's type implements a ClientWithGetMinimumBalance when the RPC supports the GetMinimumBalanceForRentExemptionApi, and a ClientWithFetchAccounts when it supports both the GetAccountInfoApi and the GetMultipleAccountsApi. The return type reflects the interfaces available on the provided RPC, so you only get the interfaces your RPC can actually back.

Because a raw Rpc object's capabilities cannot be detected at runtime, the returned object always carries both getMinimumBalance and fetchAccounts at runtime; the return type is what narrows them to the interfaces your RPC declares. Invoking a method that your Rpc does not actually support will fail when the underlying RPC method is called.

Note that this does not create a fully-fledged Kit client — it only wraps the RPC in the account interfaces above. To build a complete client, use createClient().use(solanaRpc(...)) instead, which additionally exposes the underlying RPC and other capabilities.

ClientInterfacesFromRpc<TRpc>

Example

// With an RPC supporting both APIs, the client implements both interfaces.
const client = createClientWithInterfacesFromRpc(rpc);
const rentExemptBalance = await client.getMinimumBalance(100);
const accounts = await client.fetchAccounts([addressA, addressB]);
