SWOOP Dex is an automated liquidity protocol built on the Harmony blockchain, offering decentralized, censorship-resistant, and secure trading experiences. As a fork from Uniswap, SWOOP brings familiar DeFi functionality with Harmony-specific optimizations.
How SWOOP Works
SWOOP operates as an automated liquidity protocol powered by:
- Constant product formula (
x * y = k) - Non-upgradeable smart contracts on Harmony
- 0.30% trading fee added to liquidity pools
Key features include:
- Decentralized liquidity pools for any HRC-20 token pair
- Permissionless participation - anyone can become a liquidity provider
- Arbitrage opportunities maintain price alignment with external markets

Technical Architecture
Smart Contract Modifications
SWOOP's core contracts were adapted from Uniswap V2 with minimal changes:
| Contract | Main Changes |
|---|---|
| UniswapV2ERC20 | Token name/symbol updated to SWOOP/SWP |
| UniswapV2Library | Updated init code hash and package references |
| UniswapV2Router02 | Updated package imports |
Additional Components
Four new repositories were created specifically for SWOOP:
- swoop-utils - Wallet connectors and harmony-js/core wrappers
- swoop-cli - Contract testing interface
- swoop-deployment - Deployment scripts and guides
- swoop-default-token-list - Harmony-native token list
UI/UX Adaptations
The interface required significant modifications:
- Replaced ethers.js with harmony-js/core
- Implemented custom wallet connectors for OneWallet & MathWallet
- Updated token references and chain IDs
- Modified interaction flows for Harmony compatibility
Cross-Chain Bridges on Harmony
Harmony supports multiple bridge solutions:
| Bridge | Type | Key Feature |
|---|---|---|
| Binance Chain | Trustless | Supports 100+ BNB assets |
| Iris | Permissionless | For all ERC20 tokens |
| BTC | SPV-based | Supports Bitcoin-like blockchains |
