Chains

​

The two chain objects

​

Why use them

• The Multicall3 address. BOT Chain’s Multicall3 is at 0x47FA21f684bBAD707A53a0f9BE59F1422F46C265 on both networks. The standard address that many tools assume has no code on testnet. With the SDK’s chain objects, viem’s multicall and wagmi’s useReadContracts work without any extra setup.
• The explorer API URL. blockExplorers.default.apiUrl points at BOTScan’s v2 API, which the explorer client uses.

​

How to use them

import { createPublicClient, http } from "viem";
import { botChain, botChainTestnet } from "@uzolabs/sdk/chains";

// Choose the network once and pass the chain everywhere.
const chain = process.env.NETWORK === "mainnet" ? botChain : botChainTestnet;
const client = createPublicClient({ chain, transport: http() });

console.log(chain.name, await client.getChainId());
