verifyEIP6492Signature params type incompatible with OP stack chains

[freeatnet]

Steps to reproduce:

1. Set up a TypeScript project with the latest @zerodev/sdk (just the package, no client-side required).
2. Write code to verify a signature with verifyEIP6492Signature (example below).

Expected: code should compile.
Observed: TypeScript error when client is an OP stack chain client.

Package versions:

• @zerodev/sdk: 5.3.10
• viem: 2.17.0 (due to permissionless requiring viem < 2.18.0)

Triage:
It appears that viem expects a generic to be used to type the PublicClient instance correctly.

Repro code

import { verifyEIP6492Signature } from "@zerodev/sdk";
import { createPublicClient, http } from "viem";
import { arbitrum, base, mainnet, optimism } from "viem/chains";

const mainnetPublicClient = createPublicClient({
  chain: mainnet,
  transport: http(),
});

const arbPublicClient = createPublicClient({
  chain: arbitrum,
  transport: http(),
});

const optPublicClient = createPublicClient({
  chain: optimism,
  transport: http(),
});

const basePublicClient = createPublicClient({
  chain: base,
  transport: http(),
});
