1 function split(params): CustomTransport;

Defined in: aa-sdk/core/src/transport/split.ts:43

The Split Transport allows you to split RPC traffic for specific methods across different RPC providers. This is done by specifying the methods you want handled specially as overrides and providing a fallback transport for all other methods.

Example

1 import { createPublicClient, http } from "viem";
2 import { split } from "@aa-sdk/core";
3 
4 const bundlerMethods = [
5   "eth_sendUserOperation",
6   "eth_estimateUserOperationGas",
7   "eth_getUserOperationReceipt",
8   "eth_getUserOperationByHash",
9   "eth_supportedEntryPoints",
10 ];
11 
12 const clientWithSplit = createPublicClient({
13   transport: split({
14     overrides: [
15       {
16         methods: bundlerMethods,
17         transport: http(BUNDLER_RPC_URL),
18       },
19     ],
20     fallback: http(OTHER_RPC_URL),
21   }),
22 });
