We're excited to introduce our upcoming protocol, Mikoshi, which is a binary option market on Oasys powered by Saisen.
Mikoshi aims to provide a fast, game-like trading experience that accelerates activity and liquidity within the Oasys ecosystem.
Mikoshi is a short-term binary options market on Oasys, where users predict the price movement of crypto assets over the next few minutes.
Users place bets in pOAS on either “UP” or “DOWN.”
If the price moves in the selected direction at the settlement time, the user wins a payout in pOAS. If not, the user loses the amount they bet.
Simple gameplay: Just choose UP or DOWN
Fixed multiplier payout: Win 1.7x when correct
Fast results: Short timeframes & rapid settlement cycles
Vault-based liquidity: Rewards paid from an on-chain house vault
pOAS-based economy: Designed for high turnover & liquidity circulation inside Oasys
Users can choose settlement duration:
1 minute
3 minutes
5 minutes
Currently supported:
BTC
ETH
Amount | |
|---|---|
Minimum Bet | 10 pOAS |
Maximum Bet | 20,000 pOAS |
Mikoshi uses a fixed-multiplier payout model.
Payout rate: 1.70x
Platform fee: 15% (deducted from the bet amount)
Effective stake = Bet × 0.85
Payout if win = Effective stake × 2.0 = Bet × 1.70
Mikoshi operates using an on-chain Liquidity Vault, external oracle price feeds, and a fixed fee model. This section explains the core mechanics behind the product.
All payouts are made from a dedicated Vault that acts as the counterparty to users’ bets.
Liquidity is pre-funded by the house
When users lose, the lost amount is added to the Vault
When users win, payouts are taken from the Vault
Price settlement uses aggregated external oracle sources to ensure fairness and resistance to manipulation.
We reference multiple feeds, including:
Hyperliquid
Aerodrome
The settlement price is determined from the aggregated feed at the exact settlement timestamp.
Mikoshi applies a 15% fee on the bet amount.
Mikoshi is simple — just predict whether the price will go UP or DOWN within a short time window.
Choose the underlying asset:
BTC
ETH

Select the settlement time:
1 minute
3 minutes
5 minutes

Set the amount of pOAS you want to bet:
Minimum: 10 pOAS
Maximum: 20,000 pOAS

Choose:
UP — if you expect the price to be higher at settlement
DOWN — if you expect the price to be lower

Mikoshi will lock your bet and settle based on oracle pricing at the end of the selected duration.
If you win, the payout in pOAS is automatically transferred to your wallet. If you lose, your bet amount is not returned.
Mikoshi is a short-term binary options trading dApp built on Oasys and powered by Saisen. Users can bet pOAS on short-term price movements of crypto assets and enjoy fast, game-like trading rounds. Mikoshi aims to expand liquidity circulation and activate the Oasys ecosystem by providing a fun, simple, and high-engagement trading experience.
Predict. Bet. Win.
