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. testnet-1.seismictest.net)

explorerUrl

string

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.
