What we built
IOPN DEX is the first decentralized exchange built natively for OPN Chain. It is an automated market maker (AMM) that lets anyone swap tokens or provide liquidity directly on-chain — no intermediaries, no order books, no sign-ups.
Why
OPN Chain is fast, EVM-compatible, and has near-zero fees, but the ecosystem lacked a core piece of DeFi infrastructure: a place to trade tokens and bootstrap liquidity. IOPN DEX fills that gap and gives every other project on OPN Chain a foundation to build on.
How it works
- Liquidity providers deposit a pair of tokens into a pool and receive LP tokens representing their share.
- Traders swap against these pools using the constant-product formula (x * y = k).
- Each trade charges a 0.30% fee that goes to liquidity providers, rewarding them for supplying liquidity.
- Native OPN is fully supported: it is automatically wrapped to WOPN for routing, so users trade and pool with the chain's native coin seamlessly.
What's included
- A full set of AMM smart contracts deployed on OPN testnet: Factory, Pair, Router, and Wrapped OPN.
- A clean, beginner-friendly web app for swapping, adding/removing liquidity, and claiming demo tokens from a built-in faucet.
- One-click wallet connection with automatic OPN network detection and switching.
Try it
Connect a wallet on the demo, claim demo tokens (tUSD, tBTC) from the Faucet tab, then swap or add liquidity. Everything settles on-chain in about one second.
