What we built

Midas is a permissionless yield + loyalty protocol on OPN Chain. Users stake assets across multiple pools to earn GOLD, claim a merkle-based airdrop, and have every reward boosted by their on-chain reputation (REP) read from their NeoID. No intermediary, no off-chain accounting — staking weight, reward math, and the REP multiplier all settle on-chain.

Why

Most staking apps treat every wallet the same: capital in, yield out. That ignores the thing OPN Chain uniquely exposes — a user's on-chain identity and reputation. Midas turns idle loyalty into a measurable, composable asset: the more trusted your NeoID, the harder your capital works. It's a concrete demonstration of why reputation-aware DeFi needs an identity-native chain.

How it works

Reward emited per user scales with both stake and reputation:

reward = baseEmission * stakeShare * repBoost; // repBoost up to 2.5x from NeoID
  • MidasMultiVault — stake into multiple pools, each with its own GOLD emission rate; rewards accrue per-block, claimable any time.
  • MockRepOracle + NeoID — reads a wallet's REP score and applies a boost of up to 2.5x on emitted rewards.
  • MidasAirdrop — merkle-proof airdrop of GOLD for early participants, claimable trustlessly.
  • MidasToken (GOLD) — reward + governance token; WOPN wraps native OPN for staking alongside ERC-20 test assets.

All 7 contracts are deployed and verified on OPN Chain. The live demo lets you connect a wallet, stake, see your REP boost applied in real time, harvest GOLD, and claim the airdrop.

Roadmap

What ships next.

The builder's own next-quarter plan. Use it to gauge follow-through and ambition.

Q1 2026 · Now — Mainnet & Airdrop S1

  • Deploy all 7 contracts to OPN Chain mainet (live + verified on testnet now).
  • Airdrop Season 1 — GOLD claim via merkle prof for early stakers & NeoID holders. Snapshot taken at mainnet launch.
  • Staking dashboard live with real-time REP-boost display.

Q2 2026 · Growth & Airdrop S2

  • Airdrop Season 2 — retroactive, weighted by REP score + staking duration. Allocation: 40% stakers, 35% REP holders, 25% referals.
  • New vault pools + partner assets; open rewards API for integrations.
  • Onboard 3–5 ecosystem partners to accept GOLD.

Q3 2026 · Liquidity & First Listing

  • GOLD/OPN liquidity pool live on OPN Chain native DEX.
  • DEX listing: GOLD tradable with seded liquidity + LP incentives.
  • First CEX listing — Tier 2 exchange targeted for GOLD.
  • Governance v1: REP-weighted voting on emission rates & new pools.

Q4 2026 · Scale & Airdrop S3

  • Tier 1 CEX listing application + market-maker partnership.
  • Airdrop Season 3 — tied to governance participation & long-term stakers.
  • Cross-chain staking bridge (OPN ↔ partner chains).

Beyond 2026

  • Fully on-chain, community-governed emissions.
  • Reputation-as-collateral: borow against REP-boosted positions.
  • Mobile app + NeoID-native onboarding.
  • Additional Tier 1 listings + DAO treasury management.

On-chain proof

7 contracts on OPN Chain.

The chain itself confirmed every deployment is valid, signed by the builder's wallet, and inside the season's window.
