Why Arbnomo?
Binary options trading in Web3 is rare. Real-time oracles and sub-second resolution have been the missing piece.
Pyth Hermes delivers millisecond-grade prices for 300+ assets (crypto, stocks, metals, forex).
Arbitrum Sepolia — low fees and fast finality for deposits and withdrawals.
House balance — place unlimited bets without signing a transaction every time; only deposit/withdraw hit the chain.
5s, 10s, 15s, 30s, 1m rounds with oracle-bound settlement.
Arbnomo brings binary options to Arbitrum Sepolia with transparent, on-chain settlement.

Competitive Landscape
Segment | Examples | Limitation vs Arbnomo |
|---|---|---|
Web2 binary options | Binomo, IQ Option, Quotex | Opaque pricing, no on-chain settlement; users do not custody funds. |
Crypto prediction markets | Polymarket, Kalshi, Azuro | Event/outcome markets (e.g. "Will X happen?"), not sub-minute price binary options; resolution in hours or days. |
Crypto derivatives (CEX) | Binance Futures, Bybit, OKX | Leveraged perps and positions; not short-duration binary options (5s–1m) with oracle-bound resolution. |
On-chain options / DeFi | Dopex, Lyra, Premia | Standard options (calls/puts), complex UX; no simple "price up/down in 30s" binary product. Lack of modes. |
Arbitrum Sepolia binary options | — | No on-chain binary options dApp; Arbnomo fills this gap. |
Arbnomo's differentiation: On-chain binary options on Arbitrum Sepolia with sub-second oracle resolution (Pyth Hermes), house balance for instant bets, and dual modes (Classic + Box) in one treasury.
Future
Endless possibilities across:
Stocks, Forex — Expand beyond crypto into traditional markets via oracles.
Options — Standard options (calls/puts) on top of the same infrastructure.
Derivatives & Futures — More products for advanced traders.
DEX — Deeper DeFi integration and on-chain liquidity.
Ultimate objective: To become the next Polymarket for binary options in the World.
