DEX Whitelist Protection

How LazaiTrader ensures your funds only interact with safe, approved exchanges.

Why Whitelisting Matters​

In DeFi, your wallet can interact with any smart contract. This creates risks:

RiskDescriptionConsequence
Malicious contractsFake DEXs that steal fundsTotal loss
Phishing approvalsTricking you into approving bad contractsFunds drained
Rug pullsDEX disappears with liquidityTrade fails, funds lost

LazaiTrader's whitelist eliminates these risks.

How the Whitelist Works​

At the Factory Level​

The LazaiWalletFactory maintains a master whitelist:

┌─────────────────────────────────────────────────────────┐
│              LazaiWalletFactory                          │
├─────────────────────────────────────────────────────────┤
│                                                         │
│  Whitelisted DEXs:                                      │
│  ✅ 0xF9a6d8... (HerculesDEX - Metis)                  │
│  ✅ 0x4704759... (LazaiSwap - Testnet)                 │
│                                                         │
│  All other addresses: ❌ BLOCKED                        │
│                                                         │
└─────────────────────────────────────────────────────────┘

At the Wallet Level​

Every SCW checks the factory before executing trades:

Trade Request → SCW → Check Factory Whitelist → Execute or Reject
// From LazaiTradingWallet.sol
modifier onlyWhitelistedDEX(address dex) {
    require(factory.isDEXWhitelisted(dex), "DEX not whitelisted");
    _;
}

What Gets Blocked​

Trade Attempts to Non-Whitelisted Contracts​

❌ BLOCKED: Trade to 0xMalicious...
Reason: DEX not whitelisted
Result: Transaction reverts, funds safe

Even the Bot Can't Bypass​

The bot operator has permission to call trade functions, but:

  • Every trade checks the whitelist
  • Non-whitelisted addresses always fail
  • No override possible

Whitelisting Criteria​

Before a DEX is whitelisted, we verify:

Whitelist Management​

Who Controls the Whitelist?​

The factory owner (LazaiTrader team) manages the whitelist:

  • Can add new DEXs after verification
  • Can remove DEXs if issues arise
  • Changes apply to all SCWs immediately

Adding New DEXs​

When we expand to new chains or add DEX support:

  1. DEX is reviewed and verified
  2. Added to factory whitelist
  3. All users can trade on it automatically
  4. Announced in release notes

Removing a DEX​

If a DEX becomes unsafe:

  1. Removed from whitelist immediately
  2. Existing trades complete normally
  3. New trades to that DEX blocked
  4. Users notified of change

What If I Want to Use Another DEX?​

Currently, you can only trade through whitelisted DEXs via LazaiTrader. Options:

  1. Wait for addition - Request we add the DEX
  2. Withdraw and trade - Move funds to your EOA and trade directly
  3. Use directly - Your EOA can interact with any contract
info

The whitelist only affects trades through your SCW via the bot. Your personal wallet (EOA) has no restrictions.

FAQs​

Can I request a DEX be whitelisted?​

Yes, contact us with the DEX details. We'll evaluate based on our criteria.

What if a whitelisted DEX gets hacked?​

  • We'd remove it from the whitelist immediately
  • Existing funds aren't affected (they're in your SCW, not the DEX)
  • Only pending trades could be impacted

Can I see trade transactions?​

Yes, all trades are on-chain. Check your SCW address on the block explorer.
