Chain Config

Lit Protocol uses dedicated blockchain networks for managing PKP ownership, permissions, and payment operations. If you’re using one of the testnets: Naga Dev or Test, you’ll connect to Chronicle Yellowstone, while production applications using Naga Mainnet (COMING SOON) will use the Lit Chain. Configuration details for both networks are below:

Chronicle Yellowstone - Testnet
Lit Chain - Mainnet

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.
