What we built
IOD DEX is a complete DeFi suite on OPN Chain, built around the native IOD token (IOPn + DEX). It bundles six core money-market and trading primitives into one simple app:
- Swap — constant-product AMM (Uniswap V2 style), 0.30% fee
- Liquidity — add/remove liquidity, earn trading fees, create new pools
- Staking — stake IOD, earn IOD rewards continuously
- Farming — multi-pool MasterChef, stake LP tokens for IOD yield
- Lending/Borrowing — supply USDT to earn, borrow against IOD collateral, with health factor + liquidation
- Airdrop & Referral — Merkle airdrop plus on-chain referral commissions paid in IOD
Why
OPN Chain needs core financial infrastructure that other builders and users can rely on. Instead of a single demo feature, we shipped the full stack a real DeFi ecosystem needs — trading, liquidity, yield, and credit — so the chain has working primitives from day one. Everything is live, tested, and verified on testnet, not a mockup.
How it works
- 10 Solidity contracts (OpenZeppelin patterns: SafeERC20, ReentrancyGuard, capped minting)
- Reward emitters (Staking, MasterChef) are authorized IOD minters, capped by MAX_SUPPLY
- Referral commissions accrue on every swap/harvest and are paid as freshly minted IOD — never reducing users' own rewards
- Lending uses an over-collateralized model with a configurable price oracle and liquidation bonus
- React + ethers v6 frontend; one-click faucet to try every feature
Proof it works
- All contracts deployed and verified on the OPN testnet explorer
- Full end-to-end run on live testnet: 21/21 feature steps passing (faucet, swap, liquidity, staking, farming, lending, airdrop, referral)
- 8/8 unit tests passing, including LTV enforcement
- Open source: github.com/anlop111/IOD-Dex-opn-chain
Roadmap

What ships next.
The builder's own next-quarter plan. Use it to gauge follow-through and ambition.
Q2 2026 — Now (live on testnet)
- 10 contracts deployed & verified on OPN testnet; 21/21 end-to-end feature steps passing
- Swap, liquidity, staking, farming, lending, airdrop and referral all working
- Finalize IOD tokenomics: supply cap, emission schedule, fee-sharing, treasury allocation
Q3 2026 — Hardening & TGE
- Replace the manual lending price with a real on-chain oracle (AMM TWAP + fallback feed)
- Third-party security review of core contracts (AMM, lending, reward minting)
- TGE (Token Generation Event): public IOD launch with initial liquidity and airdrop to early testnet users
- DEX listing: open the IOD/USDT and IOD/OPN pairs on our own AMM as the primary on-chain market
Q4 2026 — Mainnet & growth
- Mainnet launch on OPN Chain with audited contracts
- Liquidity incentive program to bootstrap depth on key pairs
- External DEX listings: list IOD on leading multi-chain DEX aggregators and partner DEXs for wider reach
- Analytics dashboard: TVL, volume, APR and utilization in real time
Q1 2027 — CEX & ecosystem
- CEX listings: pursue tier-2 centralized exchange listings first, then tier-1, with market-making support
- Open SDK/API so other OPN builders can integrate swap & lending as primitives
- Governance: IOD-weighted voting on emissions, listings, and risk parameters
- Onboard ecosystem partners and institutional liquidity (with IOPn GTM support)
Beyond
- Cross-chain via IBC once available on OPN Chain
- More markets: additional collateral assets and isolated lending pools
- Mobile-first experience
On-chain proof
03/03
10 contracts on OPN Chain.
The chain itself confirmed every deployment is valid, signed by the builder's wallet, and inside the season's window.
