About PlayGacha
A custom ERC-404 lottery project on Base

Project Overview
Playgacha.xyz is a decentralized lottery system on the Base network using a custom ERC-404 contract. Automated. Immutable. Always fair. Every draw combines marketing virality and tokenomics buybacks into a dual flywheel that compounds growth.
How to Enter
Acquire Your Gacha
Buy at least 1 $Gacha token. Each token = 1 NFT and 1 lottery entry.
Post on X
Post your NFT on X tagging @PlayGachaXYZ. Use our default template. All tokens in your wallet are auto-entered.
Automatic Entries
Our backend tracks posts and wallets. New tokens are added automatically. Tokens you transfer out are removed. Delete your post and all entries pause until you post again.
Automated Drawings
Smart contracts instantly reward winners at the end of each draw.
Why It Works
Built-In Virality
Posting on X makes every player a promoter, fueling organic exposure.
The Marketing Flywheel
Posts → visibility → participation → liquidity → bigger prize pools. The cycle runs itself.
The Token Flywheel
Each trade powers growth. With every transaction:
1% fuels automated buybacks (supply sinks, value rises).
3% grows the prize pool.
1% supports the team.
Compounding Value
Each post drives attention. Each trade boosts liquidity. Each winner proves fairness. Together, the flywheels create unstoppable momentum.
Technology
ERC-404 Tax Standard
The first-ever custom ERC-404 Tax contract. Tokenomics are built directly into the token's core logic—buybacks, prize pools, and accounting happen at the protocol level, not bolted on.
Lottery Contract
Fully automated draw lifecycle. Rounds, entries, randomness, and payouts are handled on-chain with a complete audit trail.
Chainlink VRF
Cryptographically verifiable randomness ensures every draw is transparent, unpredictable, and tamper-proof.
Base Network
Deployed on Base (Ethereum L2) for low fees, fast finality, and Ethereum-grade security.
Smart Contracts
Audited, deterministic, and designed for continuous automation without manual intervention.
Tokenomics
Playgacha uses a 5% tax model integrated at the contract level. This ensures that every transaction fuels the ecosystem:
1% Buybacks — Automated buybacks reduce supply and strengthen price momentum.
3% Prize Pool — Directly expands lottery rewards, making each draw bigger and more attractive.
1% Team — Supports long-term development and ecosystem growth.
This design creates a natural flywheel: volume drives prize pools, buybacks support token value, and posts generate visibility. Every player powers the system just by participating.
