Chain Config

Depending on the Lit Protocol Network that you’re using, you’ll connect to one of the following Lit chains. For those using one of the Lit testnets (Naga Dev or Naga Test) will use the Chronicle Yellowstone Chain. Those building in production on the Naga Mainnet (COMING SOON) will use the Lit Chain. Configuation details for both can be found below:

Viem Chain Config for the Chronicle Yellowstone network

import { Chain, http } from "viem";

export const viemChainConfig: Readonly<Chain> = Object.freeze({
  id: 175188,
  name: "Chronicle Yellowstone",
  nativeCurrency: {
    name: "Chronicle Yellowstone",
    symbol: "tstLPX",
    decimals: 18,
  },
  rpcUrls: {
    default: {
      http: ["https://yellowstone-rpc.litprotocol.com/"],
    },
    public: {
      http: ["https://yellowstone-rpc.litprotocol.com/"],
    },
  },
  blockExplorers: {
    default: {
      name: "Yellowstone Explorer",
      url: "https://yellowstone-explorer.litprotocol.com/",
    },
  },
});

Alternatively, we also provide a helper function to get the viem chain config. You can use

litClient.getChainConfig().viemConfig

to get the viem chain config. See Lit Client Reference for more details.
