What we built
OPE DEX is a full-stack DeFi suite on OPN Chain (testnet, chainId 984). It bundles six permissionless primitives behind one frontend:
- DEX — a Uniswap V2 fork (Factory, Pair, Router, WOPN) for swapping OPN ↔ OPEPE and providing liquidity.
- Staking — stake OPEPE, earn OPEPE rewards on a Synthetix-style roling reward schedule.
- Presale — contribute OPN, claim tokens on success or refund if the soft cap isn't met.
- Launchpad — anyone can deploy and fund their own presale in one transaction.
- Merkle Airdrop — gas-efficient claims verified against an on-chain Merkle root.
- MemeToken — the $OPEPE ERC-20 at the center of it all.
Why
Meme tokens drive real on-chain activity, but the tooling is scattered across many dApps. We wanted to show that a single chain can host the entire lifecycle — launch, trade, pool, stake, reward — with no intermediary, all open-source and verifiable. The chain itself is the financial backend.
How it works
- 9 Solidity contracts deployed and source-verified on the OPN testnet explorer.
- Smart contracts in Solidity 0.8.x, built and tested with Hardhat (full test suite + an on-chain smoke test covering 13/13 features end-to-end with a live wallet).
- Frontend in Next.js + wagmi + RainbowKit, deployed on Vercel.
- Everything is permissionless and on-chain: no backend server holds funds or state.
Try it
Add the network to MetaMask, then connect:
Network: OPN Testnet
chainId: 984
Actions: swap OPN/OPEPE, add liquidity, stake, join a presale, claim airdrop
Repo and all verified contract addresses are linked in the submission.
