[ecosystem] Viem support for Nibiru EVM needed for Uniswap V3 integration

[Unique-Divine]

Objective

Enable integration with Uniswap V3 powered by Oku by implementing "Viem support" that was requested on Telegram.

The Ask

• Write a TypeScript example demonstrating how to use Viem to interact with Nibiru and add it to the docs.
• Chain Support for Nibiru
  • (i) Add Nibiru as one of the supported "viem/chains" → But first, investigate this further to see if a pull request against the Viem repository is a hard requirement.
  • (ii) As an alternative to (i), we could export a constant from @nibiruchain/nibijs that implements the Chain type from viem. Another option could be to simply add TS code that can be copy-pasted right out of the docs in case people don't want to import another dependency.

What is Viem?

Viem - TypeScript Interface for Ethereum

Usage

import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'
 
const publicClient = createPublicClient({ 
  chain: mainnet,
  transport: http()
})
