### Play. Bid. Pray.

Today, we’re so excited to introduce Saisen, a gamified auction ritual built on the Oasys blockchain. In this on‑chain game, users bid in pOAS or OAS to compete for the pooled prize, and every bid is a mix of calculation and chance.

> Inspired by the Japanese “賽銭 (saisen)” tradition of ritual coin offerings, we bring that spirit on‑chain—turning every Bid into a collective ceremony where luck meets strategy.

What is Saisen
--------------

**Saisen** is a fully on-chain GameFi protocol that reimagines the “last-bid” auction format with strategic depth, and randomized rewards.

### Basic Rule

At its core, players bid using pOAS or OAS to compete in time-based prize pools. Each new bid resets a countdown timer. When the timer runs out:

*   **68%** of the pool goes to the last bidder.
    
*   **20%** is equally distributed among 10 randomly selected past bids.
    
*   **12%** House Edge is taken: 8% is distributed to SAISN‑OAS LP stakers. 4% goes to the Treasury.
    

### Game Phases

**Bootstrap Phase (First 24 hours)**

*   The game runs without a winner — no timer stop or prize distribution.
    
*   Minimum bid is fixed at **10 pOAS**.
    

**Main Game Phase**

Once the Bootstrap Phase ends, the game enters its core loop:

1.  **Minimum bid** is set to **0.5% of the current pool**.
    
2.  Each new bid **resets a 1-hour countdown timer**.
    
3.  The game ends when the timer runs out without any new bids.
    

### Prize

Prize will be distribute in pOAS:

1.  **68%** of the pool goes to the last bidder.
    
2.  **20%** is equally distributed among 10 randomly selected past bids.
    

### House Edge

1.  A **12% House Edge** is taken from the winner’s share:
    
    *   **8%** is distributed to **SAISN‑OAS LP stakers**.
        
    *   **4%** goes to the **Treasury**.
        

SAISN Tokenomics
----------------

### Overview

*   **Total Supply:** 100M SAISN
    

The SAISN token is the core value-capturing asset of the Saisen ecosystem. It fuels and governs the game’s economy.

### Utility

*   **Revenue Sharing** — 10% of every prize (from House Edge) is distributed to SAISN-OAS LP stakers.
    
*   **Liquidity Incentives** — SAISN emissions reward LP stakers and players.
    
*   **Governance** — Future DAO proposals and upgrades may be governed by SAISN holders.
    

### SAISN Allocation

**Bid Rewards** **\- 45%**

*   Vesting: 24 months, non-linear (0.5% weekly decay)
    
*   Saisen rewards active bidders with daily SAISN emissions. The more you bid, the more you earn—up to 10% of the daily allocation per user. This encourages consistent participation through fair, proportional rewards.
    

**LP Staker Rewards** – 20%

*   Vesting: 24 months, non-linear (0.5% weekly decay)
    

Staking SAISN-OAS LP tokens earns you dual rewards: a share of protocol fees and SAISN emissions. Locking increases your rewards, while instant unstaking forfeits up to 50% of your LP as a penalty. This penalty gradually decreases over a cooldown period and is redistributed to remaining stakers — rewarding long-term commitment.

**Treasury** – 15%

*   Vesting: 24 months, linear
    

**Team** – 10%

*   Vesting: 24-month linear
    

**Oasys Foundation (Seed LP)** – 5%

*   Vesting: 100% at TGE
    

**Oasys Foundation (for pOAS Airdrop)** – 5%

*   Vesting: 24 months, linear
    

### Bid Reward Boost

Saisen offers boosted rewards for players who hold tokens from partner projects. Your SAISN rewards can increase, based on the number of different eligible tokens you own — not the quantity of each.

#### Eligible Tokens

*   MCHC
    
*   BPC
    
*   TORA
    
*   OASSY
