Overview
CATHOSI is a 21,000,000-edition pixel cat NFT collection on BNB Smart Chain — bitcoin's hard cap, nyan cat's energy. $CATHOSI trades against $BTCB, and the trading tax pays cat holders in real bitcoin on BNB Chain.
04 DOCUMENTATION
HOW IT WORKS.
One artwork, 21,000,000 editions
There are no traits, no rarity tiers and no generative DNA. Every CATHOSI is the same legendary cat, carries the same reward weight, and is interchangeable — scarcity comes from the fixed 21,000,000 cap alone.
Mint
Minting costs 0.001 BNB (retained in the vault reserve pool) or 21,000 CATHOSI, burned instantly. A wallet may hold at most 21 cats — mints and transfers that would exceed the cap revert. The owner must open minting via setMintOpen(true) on the contract before the public mint button is active.
What you get
One legendary artwork, 21,000,000 editions. Every cat is identical and every cat earns the same share of the $BTCB reward pool. Pick BNB or CATHOSI at mint time, confirm the transaction, and the cat is yours.
Tax & pools
CATHOSI / BTCB carries a 3% / 3% buy/sell tax collected in $BTCB. Every inbound tax deposit is split on arrival: 70% to the protocol reserve pool and 30% to the NFT reward pool.
Automatic pro-rata rewards
Every 7 minutes the vault settles the reward pool pro-rata across all minted cats — one cat, one share. Rewards accrue to the current owner and follow the NFT on transfer. Anyone can trigger the settlement; holders can also pull accrued $BTCB manually at any time from the mint page.
Metadata API
Token metadata is served at /api/public/metadata/{id} and the artwork at /api/public/image/{id}, both marketplace-compatible.
