Code Examples

Comprehensive examples showcasing real-world Omne blockchain applications. From simple payments to complex DeFi protocols, learn by doing.

Quick Start Examples

💳 Simple Transfer

Send OMNE tokens between accounts with automatic fee calculation.

import { OmneClient, Account } from '@omne/sdk'

const client = new OmneClient({ network: 'testnet' })
const account = await Account.fromPrivateKey(privateKey)

const result = await client.transfer({
  from: account.address,
  to: 'omne1recipient...',
  amount: '1000000', // 1 OMNE
  memo: 'Payment for services'
})

console.log('Transaction:', result.hash)

📊 Balance Check

Query account balances and transaction history.

import asyncio
from omne_sdk import OmneClient

async def check_balance():
    client = OmneClient(network='testnet')
    
    balance = await client.get_balance('omne1address...')
    print(f"Balance: {balance.amount} {balance.denom}")
    
    # Get transaction history
    history = await client.get_transactions('omne1address...')
    for tx in history:
        print(f"{tx.type}: {tx.amount} at {tx.timestamp}")

asyncio.run(check_balance())

🔐 Multi-Signature

Create transactions requiring multiple signatures for enhanced security.

package main

import (
    "github.com/omne-foundation/omne-go-sdk/client"
    "github.com/omne-foundation/omne-go-sdk/multisig"
)

func main() {
    // Create 2-of-3 multisig account
    accounts := []*account.Account{account1, account2, account3}
    multisigAddr := multisig.CreateAddress(accounts, 2)
    
    // Create transaction
    tx := &transactions.TransferTx{
        FromAddress: multisigAddr,
        ToAddress:   "omne1recipient...",
        Amount:      "5000000", // 5 OMNE
    }
    
    // Sign with required accounts
    signedTx := multisig.Sign(tx, account1, account2)
    result, _ := client.Broadcast(ctx, signedTx)
}

📡 Real-time Events

Subscribe to blockchain events and real-time notifications.

// Subscribe to new blocks
const blockStream = client.subscribeToBlocks()
blockStream.on('block', (block) => {
  console.log(`New block #${block.height}`)
  console.log(`Transactions: ${block.txCount}`)
})

// Subscribe to account transactions
const txStream = client.subscribeToTransactions(accountAddress)
txStream.on('transaction', (tx) => {
  console.log(`${tx.type}: ${tx.amount} OMNE`)
  
  if (tx.type === 'receive') {
    console.log(`Received payment from ${tx.sender}`)
  }
})
