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.
