transfer amount is within the minimum and maximum limits.e) Confirm the transaction:Click the "Transfer" or "Swap" button.Your wallet will prompt you to confirm the transaction.Review the gas fees and approve the transaction.Monitoring Your TransferAfter initiating the transfer:a) The interface will show a progress indicator.b) You can track the status of your transfer on both the source and destination networks.c) Once completed, you should see the transferred assets in your wallet on the destination network.Common ScenariosLet's walk through some common scenarios:a) Transferring ETH from Ethereum to Arbitrum:Connect your wallet to Orbiter Bridge.Select "Ethereum" as the source and "Arbitrum" as the destination.Choose ETH as the asset.Enter the amount of ETH you want to transfer.Review fees and confirm the transaction.Wait for the transfer to complete (usually within minutes).Check your Arbitrum balance in your wallet.b) Moving USDC from Optimism to Polygon:Ensure you have USDC on Optimism.Connect your wallet and select Optimism as the source, Polygon as the destination.Choose USDC as the asset.Enter the USDC amount.Confirm the transaction and pay gas fees in ETH on Optimism.Once completed, you'll see USDC in your Polygon wallet.Gas Fees and OptimizationUnderstanding and optimizing gas fees is crucial:a) Gas fees vary by network:Ethereum Mainnet typically has the highest fees.L2 networks generally have lower fees.b) To optimize gas fees:Check gas prices using tools like ETH Gas Station.Consider transferring during off-peak hours.Use the gas price slider in your wallet to balance speed and cost.c) Some L2 networks may require you to have ETH for gas, even when transferring other assets.Troubleshooting Common IssuesIf you encounter problems:a) Transaction Stuck or Pending:Check the transaction status on the network's block explorer.Consider speeding up the transaction by increasing gas price.For prolonged delays, contact Orbiter Bridge support.b) Insufficient Funds:Ensure you have enough of the asset you're transferring.Don't forget to account for gas fees on both networks.c) Network Congestion:During high congestion, transfers may take longer.Consider postponing non-urgent transfers during these times.Security Best PracticesTo ensure the safety of your assets:a) Always double-check the Orbiter Bridge URL.b) Verify transaction details before confirming.c) Start with small amounts when using the bridge for the first time.d) Keep your wallet's private keys secure and never share them.e) Be cautious of phishing attempts and fake websites.Advanced UsageFor more experienced users:a) Multiple Asset Management:You can use Orbiter Bridge to balance your portfolio across networks.Consider the fee structures on different networks for optimal asset allocation.b) Arbitrage Opportunities:Monitor price differences of assets across networks.Use Orbiter Bridge for quick transfers to take advantage of these differences.c) Integrating with DeFi Protocols:Use Orbiter Bridge in conjunction with various DeFi protocols across different networks.This can help you access unique yield opportunities or liquidity pools.Interacting with Smart ContractsFor developers or advanced users who want to interact directly with Orbiter Bridge smart contracts:a) Contract Addresses:Each network has its own Orbiter Bridge contract address.Always verify contract addresses from official sources.b) Function Calls:Common functions include deposit(), withdraw(), and transfer().Ensure you understand the parameters and gas limits for each function.c) Using Web3 Libraries:Libraries like Web3.js or ethers.js can be used for programmatic interactions.Example of initiating a transfer using Web3.js:javascriptCopyconst Web3 = require('web3');
const web3 = new Web3('YOUR_RPC_URL');
const orbiterContract = new web3.eth.Contract(ABI, CONTRACT_ADDRESS);

async function transfer(amount, destinationAddress) {
 const accounts = await web3.eth.getAccounts();
 await orbiterContract.methods.transfer(destinationAddress).send({
   from: accounts[0],
   value: web3.utils.toWei(amount, 'ether')
 });
}
