Create Seismic Devnet

Factory function for custom Seismic chain configurations

Factory function that creates a RainbowKit-compatible chain configuration for any Seismic node. Use this when the pre-configured chains (seismicTestnet, sanvil, localSeismicDevnet) do not match your node's host.

Import

import { createSeismicDevnet } from "seismic-react/rainbowkit";

Parameters

Parameter	Type	Required	Description
nodeHost	string	Yes	Hostname for the node (e.g. gcp-1.seismictest.net)
explorerUrl	string	No	Block explorer URL

Return Type

RainbowKitChain -- a chain object compatible with RainbowKit's getDefaultConfig and wagmi's createConfig.

The returned chain has:

• Chain ID: 5124

• Name: Seismic

• Native Currency: ETH (18 decimals)

• RPC (HTTPS): https://<nodeHost>/rpc

• RPC (WSS): wss://<nodeHost>/ws

• Seismic transaction formatters

Usage

Basic

import { createSeismicDevnet } from "seismic-react/rainbowkit";

const myDevnet = createSeismicDevnet({
  nodeHost: "my-node.example.com",
});
// RPC: https://my-node.example.com/rpc
// WSS: wss://my-node.example.com/ws

With RainbowKit

import { getDefaultConfig } from "@rainbow-me/rainbowkit";
import { createSeismicDevnet } from "seismic-react/rainbowkit";

const myChain = createSeismicDevnet({
  nodeHost: "my-node.example.com",
});

const config = getDefaultConfig({
  appName: "My App",
  projectId: "YOUR_PROJECT_ID",
  chains: [myChain],
});

With wagmi Config

import { http, createConfig } from "wagmi";
import { createSeismicDevnet } from "seismic-react/rainbowkit";

const myChain = createSeismicDevnet({
  nodeHost: "my-node.example.com",
});

const config = createConfig({
  chains: [myChain],
  transports: {
    [myChain.id]: http(),
  },
});

With Explorer URL

const myChain = createSeismicDevnet({
  nodeHost: "my-node.example.com",
  explorerUrl: "https://explorer.example.com",
});

Notes

• The nodeHost parameter should be the bare hostname without a protocol prefix or path. HTTPS and WSS URLs are constructed automatically.

• The Seismic icon is included automatically for display in RainbowKit's chain selector.

• The underlying implementation delegates to createSeismicDevnet from seismic-viem and wraps the result with RainbowKit metadata.
