Address Validation

Use client-side validation: 
import { ethers } from 'ethers';

const validateWalletAddress = (address, network) => {
  if (['POLYGON', 'ERC20', 'ARBITRUM', 'BSC'].includes(network)) {
    return ethers.utils.isAddress(address);
  }
  
  if (network === 'SOLANA') {
    return /^[1-9A-HJ-NP-Za-km-z]{32,44}$/.test(address);
  }
  
  if (network === 'TRON') {
    return /^T[a-zA-Z0-9]{33}$/.test(address);
  }
  
  return false;
};
