viem

Mainnet

MIZUHIKI Mainnet is not yet included in viem/chains, so define the chain manually:

import { defineChain } from 'viem'

export const mizuhiki = defineChain({
  id: 6498,
  name: 'MIZUHIKI Mainnet',
  nativeCurrency: {
    decimals: 18,
    name: 'Mizu',
    symbol: 'MIZU',
  },
  rpcUrls: {
    default: {
      http: [`https://rpc.mizuhiki.io`],
    },
  },
  blockExplorers: {
    default: { name: 'Explorer', url: 'https://mizuhiki.blockscout.com' },
  },
})

Awaji Testnet

For viem@2.50.3 or newer, the Awaji testnet ships with viem:

import { createPublicClient, http } from 'viem'
import { mizuhikiTestnetAwaji } from 'viem/chains'

const client = createPublicClient({
  chain: mizuhikiTestnetAwaji,
  transport: http()
})

For older versions, define the chain manually:

import { defineChain } from 'viem'

export const awaji = defineChain({
  id: 6497,
  name: 'MIZUHIKI Testnet Awaji',
  nativeCurrency: {
    decimals: 18,
    name: 'Mizu',
    symbol: 'MIZU',
  },
  rpcUrls: {
    default: {
      http: [`https://rpc.awaji.mizuhiki.io`],
    },
  },
  blockExplorers: {
    default: { name: 'Explorer', url: 'https://awaji.blockscout.com' },
  },
})
