DEX

The trading core of MegaFi. DEX enables instant token swaps and efficient capital deployment through MegaPools powered by concentrated liquidity.

At a Glance​

  • Swap tokens with sub-50ms execution and minimal slippage
  • Provide liquidity in custom Liquidity Zones for maximum capital efficiency
  • Earn trading fees from every swap through your pool
  • LP positions represented as transferable NFTs
  • Real-time pool updates enable continuous capital optimization
  • Up to 95% capital utilization vs 60-70% on traditional AMMs

How It Works​

MegaPools use concentrated liquidity to improve capital efficiency. Unlike traditional constant-product pools where liquidity is spread across all prices, concentrated liquidity lets you focus capital in specific price ranges.

Traders swap tokens through MegaPools, paying a small fee on each trade.

Liquidity Providers deposit token pairs into pools, earning a portion of trading fees.

LP NFTs represent each liquidity position, tracking your specific Liquidity Zone and accumulated fees.

Key Concepts​

MegaPools​

Token pair pools that facilitate swaps. Each MegaPool contains two tokens (e.g., ETH/USDC) and executes swaps between them.

Pools use an automated market maker formula to price tokens. As trades occur, prices adjust automatically to maintain balance.

Liquidity Zones​

Custom price ranges where you concentrate your liquidity. By providing liquidity only in zones where trading occurs, you earn more fees per dollar of capital.

Choose wide zones for stable, predictable earnings or narrow zones for higher returns with more active management.

LP NFTs​

Your liquidity position is represented as an NFT. Each NFT tracks:

  • Which pool you're providing to
  • Your Liquidity Zone boundaries
  • Accumulated fees
  • Liquidity amount

LP NFTs are transferable. You can sell, trade, or hold them like any NFT.

Fee Tiers​

Different pools have different fee structures:

  • 0.05%: Stable pairs (USDC/USDT, DAI/USDC)
  • 0.3%: Standard pairs (ETH/USDC, WBTC/ETH)
  • 1%: Exotic pairs (low liquidity or volatile tokens)

Higher fees compensate for higher risk and volatility.

Capital Efficiency​

Concentrated liquidity achieves 30-50% higher capital utilization than traditional AMMs. Your assets work harder, earning more fees per dollar deployed.

Real-Time Updates​

Pool prices, liquidity positions, and fee accrual update continuously. MegaETH processes state changes in real-time, not in 12-second intervals.

This enables features impossible on block-based chains:

  • Liquidity zones that adjust based on price movement
  • Real-time fee accrual tracking
  • Instant position rebalancing

Capital Efficiency Comparison​

Traditional AMMs spread liquidity across all prices:

Price Range: $0 to $∞
Useful Liquidity: 20-30%
Capital Efficiency: Low

MegaFi concentrated liquidity focuses capital where trades happen:

Price Range: $1,800 to $2,200 (example for ETH)
Useful Liquidity: 90-95%
Capital Efficiency: High

Result: Same fee earnings with 50-70% less capital deployed.

MegaETH Advantages​

DEX leverages MegaETH's unique capabilities:

Sub-10ms Finality: Swaps execute and finalize before traditional chains process a single block.

100k+ TPS: No congestion. Swaps execute immediately even during peak activity.

Continuous Processing: Pool state updates in real-time, not at block intervals. Enables live rebalancing and instant arbitrage correction.

Ultra-Low Costs: Gas fees under $0.005 per transaction. Profitable to rebalance positions multiple times daily.

Getting Started​

As a Trader​

  1. Connect wallet
  2. Make your first swap
  3. Explore available pools and routes

As a Liquidity Provider​

  1. Choose a token pair with good volume
  2. Select your Liquidity Zone based on price expectations
  3. Deposit liquidity and receive LP NFT
  4. Monitor fees and rebalance as needed

Risk Considerations​

Providing liquidity involves risks:

Impermanent Loss: When token prices diverge, your position value may be lower than simply holding the tokens. More pronounced with volatile pairs.

Smart Contract Risk: Smart contracts are in development and have not yet been audited. Use testnet deployments with caution.

Liquidity Risk: In low-liquidity pools, your trades may experience higher slippage.

Price Risk: Token prices fluctuate. Your liquidity position value changes with market conditions.

Understand these risks before providing significant liquidity. Consider starting with small amounts.

Technical Architecture​

MegaPools are deployed as smart contracts on MegaETH. Key components:

Pool Contracts: Store liquidity and execute swaps. One contract per token pair and fee tier.

Position Manager: Tracks LP NFTs and manages position metadata.

Router: Finds optimal swap routes and executes multi-hop trades.

Oracle: Provides price data for improved routing and MEV protection.

FAQ​

What's the minimum liquidity I can provide?
No minimum. Even small amounts earn fees, though gas costs are more significant for tiny positions.

Can I remove liquidity anytime?
Yes. No lock periods. Withdraw whenever you want.

How often are fees paid?
Fees accumulate continuously with every swap. Collect them when you withdraw liquidity or manually claim.

What happens if price moves outside my zone?
Your liquidity becomes inactive (all one token). You stop earning fees until price returns to your zone. Consider wider zones or automated rebalancing.

Are LP NFTs transferable?
Yes. They're standard ERC-721 tokens. Sell or transfer like any NFT.
