Basic Usage

Installing Basic Usage Dependencies

pnpm add @appliedblockchain/silentdatarollup-viem

Basic Usage Example

import { defineChain, createPublicClient, createWalletClient } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { sdTransport } from '@appliedblockchain/silentdatarollup-viem'

const providerConfig = {
  rpcUrl: 'SILENT_DATA_ROLLUP_RPC_URL',
  chainId: 'SILENT_DATA_CHAIN_ID',
  privateKey: 'YOUR_PRIVATE_KEY',
}

const account = privateKeyToAccount(providerConfig.privateKey)

const transport = sdTransport(providerConfig)

const sdChain = defineChain({
  id: providerConfig.chainId,
  name: 'SILENT_DATA_CHAIN_NAME',
  nativeCurrency: {
    name: 'Ether',
    symbol: 'ETH',
    decimals: 18,
  },
  rpcUrls: {
    default: {
      http: [providerConfig.rpcUrl],
    },
  },
})

const publicClient = createPublicClient({
  chain: sdChain,
  transport,
})

const walletClient = createWalletClient({
  chain: sdChain,
  transport,
  account,
})

const balance = await publicClient.getBalance({ address: account.address })
console.log('Balance:', balance)

const transactionCount = await publicClient.getTransactionCount({
  address: account.address,
})
console.log('Transaction count:', transactionCount)

const recipientAddress = 'RECIPIENT_ADDRESS'
const amountInWei = BigInt('1')

const transactionHash = await walletClient.sendTransaction({
  to: recipientAddress,
  value: amountInWei,
})
console.log('Transaction Hash:', transactionHash)
