Trading on the Ethereum network can feel like paying a hidden tax. High gas fees and slow transactions make it challenging to move fast or trade small amounts without losing money.

This is where Ethereum Layer 2 networks come in. 

It allows traders to skip the network congestion and transaction costs while running transactions off-chain and securing them back into the main Ethereum blockchain. 

If you're considering trading often, paying less in fees, and capturing more profit, knowing how Layer 2s work on Ethereum is essential. Wallet Finder.ai shows you the wallets and blockchains currently making money on these cheaper, faster layers so you can follow suit and get ahead.

Layer 2 Basics in 3 Minutes

‍

A Layer 2 can be thought of as a side road running next to the main Ethereum network highway. It carries out transactions off the main chain but posts a record back to Ethereum. This way, it maintains security while easing congestion.

‍

Core Benefits

‍

● Lower transaction fees: Many Layer 2s cut gas costs by 10 to 100 times.

‍

● Faster confirmation: Trades settle in seconds instead of minutes.

‍

● Same security: They rely on the main Ethereum blockchain for final proof.

‍

Key Tech Types

‍

● Optimistic Rollups - These trust transactions by default and check only if someone challenges them. Popular examples are Arbitrum, Optimism, and Base.

‍

● ZK-Rollups - These use zero-knowledge proofs to confirm batches of transactions fast and securely. Examples include zkSync Era, Starknet, and Scroll.

‍

● Validiums / Volitions - They store data off-chain but link to Ethereum for trust. Immutable X and Polygon CDK use this method.

‍

Layer 2 networks work behind the scenes to boost transaction speed and shrink costs without sacrificing the safety traders expect from the Ethereum network.

Comparing the Top Trading-Friendly Layer 2s

‍

Not every Ethereum Layer 2 works the same for traders. Some have cheaper swaps, while others have bigger pools of money for DeFi. Here’s a quick look at five of the most popular ones for trading:

‍

‍

Each of these networks lowers transaction fees and boosts transaction speed compared to the main Ethereum blockchain. Pick the one that matches your trading style, then use WalletFinder.ai to see which wallets profit the most on each Layer 2.

How to Bridge and Start Trading in Under 10 Minutes

‍

Getting started with Ethereum Layer 2 is super easy. Below are simple steps on moving funds, skipping high transaction fees, and trading faster than the Ethereum Blockchain:

‍

Step 1: Add the Network to MetaMask

‍

First, open MetaMask and connect to the Layer 2 network you will use. You can do this automatically with Chainlist or by adding the RPC details manually. This connects your wallet to the right blockchain rollups so you can send and receive tokens off-chain.

‍

Step 2: Bridge Your Assets

‍

Then, transfer your cryptocurrencies from Layer 1 to Layer 2 on official bridges and trusted routers like Hop and Synapse. Here, smart contracts will lock down your funds on the Ethereum network and release them on Layer 2. 

Always double-check the security of the bridge to avoid any risk. 

‍

Step 3: Pick a DEX or Perpetual Platform

‍

Once your funds arrive, choose where to trade. Popular decentralized apps include Uniswap v3, SushiXSwap, Aerodrome on Base, and Vertex on Arbitrum One. These run on Layer 2, which guarantees you lower transaction costs and quicker executions than the Ethereum mainnet. 

‍

Step 4: Adjust Gas and Slippage Settings

‍

One advantage of Layer 2 networks is that they offer cheaper gas. With such tiny transaction fees, you should be able to keep your slippage settings tight, usually below 0.3%. This allows your trades to closely reflect market price and makes you less exposed to price swings. 

‍

Step 5: Track Profits with Wallet Finder.ai

‍

At last, use Wallet Finder.ai to monitor the performance of your wallet. Connect your wallet to our platform to calculate profit and loss, gas savings comparisons, as well as to follow profitable wallets in Arbitrum, Base, Optimism, or other Layer 2s. 

This will give you an idea of where your money is working well.

Advanced Trading Plays on L2s

‍

Once you’re comfortable trading on an Ethereum Layer 2, you could try some advanced tricks to make some real profits. These tricks utilize off-chain transactions, smart contract tricks, and blockchain rollups to be one step ahead of everyone else. 

‍

1. Cross-L2 Arbitrage

‍

Price differences arise whenever tokens are listed on more than one Layer 2. For instance, the same token may be slightly more expensive on Arbitrum than it is on zkSync Era. Traders can profit from this gap by buying low on one network and selling high on another. The speed of Layer 2 transactions and low fees make it feasible.

‍

2. Perpetual DEX Farming

‍

Some decentralized applications offer contracts termed perpetuals to assist paying traders in points or extra tokens. Platforms like GMX v2 on Arbitrum One, Hyperliquid, and Level Finance allow users to trade perpetuals and farm. 

As Layer 2 cuts gas costs, you can open and close trades more often without losing money on fees. This is something hard to do on Layer 1.

‍

3. Liquidity Incentive Rotations

‍

Many new Layer 2 networks launch with big bonuses for liquidity providers. These early programs can pay huge APRs for a short time. Traders jump between networks like Blast or Scroll to catch the best yield. By using WalletFinder.ai, you can track wallets that move fast between these liquidity farms and copy their path.

‍

4. Gas Sponsorship via ERC-4337

‍

Some new Layer 2 wallets use smart contract wallets with ERC-4337. This lets a “paymaster” cover your gas fees so you can pay in USDC or even trade gas-free. This trick makes decentralized finance easier for newcomers who hate managing gas in ETH.

Advanced plays like these show how flexible Layer 2 blockchains are. Combine these with WalletFinder.ai to watch how profitable wallets use these same tricks to stay ahead.

‍

Risk Checklist

‍

‍

Layer 2 makes trading cheaper and quicker, but it comes with a few risks. Keep these in mind:

‍

1. Bridge Smart-Contract Risk - Always use official or well-audited bridges. Poorly built smart contracts can get hacked, risking your funds.

‍

2. Fraud Proof/Validity Proof Delays - Optimistic rollups like Arbitrum and Optimism may need up to 7 days to settle withdrawals back to the Ethereum mainnet fully. Plan your exits early. 

‍

3. Fake Tokens & Rugpulls - Layer 2s can have copycat tokens. Always check token contract addresses on a trusted block explorer before trading.

‍

4. Liquidity Fragmentation - Liquidity can spread across many pools. Double-check the pool’s depth to avoid significant price changes when placing large orders.

‍

Staying cautious protects your profits while enjoying faster, cheaper trades on Ethereum Layer 2.
