Cross-chain trading has long been a bottleneck in decentralized finance (DeFi), requiring users to navigate multiple bridges, decentralized exchanges (DEXs), and complex transaction flows. Enter Fly, a next-generation liquidity aggregation protocol designed to simplify cross-chain swaps while maximizing speed, efficiency, and user experience.
With Fly, you can seamlessly swap assets across top blockchains—without manually bridging or interacting with multiple protocols. Whether you're moving stablecoins from Ethereum to Base or swapping memecoins across Arbitrum and BSC, Fly handles the complexity behind the scenes.
Why Cross-Chain Swaps Matter in 2025
As blockchain ecosystems grow more diverse, so does the need for frictionless asset movement. Users no longer want to jump through hoops just to access opportunities on different chains. The demand for fast, secure, and gas-efficient cross-chain transactions is higher than ever.
Fly meets this demand by aggregating liquidity from major networks and executing optimal swaps in seconds—not minutes or hours.

How Fly Works: Simple, Secure, Smart
Step 1: Connect Your Wallet
Fly integrates with popular Web3 wallets including MetaMask, WalletConnect, Coinbase Wallet, and Rabby. No matter your preferred wallet, getting started takes seconds.
Once connected, Fly instantly pulls your token balances across all supported chains—giving you a unified view of your portfolio.
Step 2: Choose Your Swap Terms
Select your source and destination chains, pick the tokens you'd like to swap, and enter the amount. Fly’s smart routing engine scans liquidity pools and bridge paths in real time to deliver the best possible rate.
You can even favorite frequently used tokens with a single click—just tap the star icon next to any token, and it’ll appear at the top of your list for faster access.
Step 3: Approve and Confirm
Review the quote, approve the transaction, and confirm. If prices fluctuate beyond your slippage tolerance during cross-chain execution, Fly will prompt you to accept an updated quote—ensuring transparency and control.
Step 4: Receive Your Assets
Sit back and relax. Your swapped assets arrive directly in your wallet on the target chain—no extra steps required.

Behind the Scenes: Solving Real DeFi Challenges
Fly addresses three major pain points in today’s decentralized finance landscape:
- Bridging Complexity
Most cross-chain solutions require users to manually bridge assets first—exposing them to delays, high fees, and potential loss if liquidity is insufficient. Fly eliminates this step entirely. - Fragmented Liquidity
Liquidity is scattered across DEXs and chains. Fly aggregates it intelligently, ensuring you always get the best available rate—without needing to compare platforms yourself. - Poor User Experience
Navigating multiple interfaces is tedious and risky. Fly offers a chain-abstracted UX, meaning you interact with one simple interface regardless of underlying complexity.
For example: Want to swap PEPE on Ethereum for Brett on Base? With Fly, you do it directly—no bridge setup, no intermediate stablecoin conversion.
