Insufficient balance

Error message

Insufficient balance

What it means

Illustrative balance guard from the security-review skill: getBalance(transaction.from) is less than the transfer amount, so the transaction would fail on-chain anyway and is rejected before signing. The sender account has insufficient funds.

```

#### Transaction Verification
```typescript
async function verifyTransaction(transaction: Transaction) {
  // Verify recipient
  if (transaction.to !== expectedRecipient) {
    throw new Error('Invalid recipient')
  }

  // Verify amount
  if (transaction.amount > maxAmount) {
    throw new Error('Amount exceeds limit')
  }

  // Verify user has sufficient balance
  const balance = await getBalance(transaction.from)
  if (balance < transaction.amount) {
    throw new Error('Insufficient balance')
  }

  return true
}
```

#### Verification Steps
- [ ] Wallet signatures verified
- [ ] Transaction details validated
- [ ] Balance checks before transactions
- [ ] No blind transaction signing
