The cat Satoshi left behind is back — and it pays in Bitcoin.
$OP_CAT is Bitcoin's most legendary opcode reborn as a cosmic cat. Paired to BTC. A 4% trading fee streams back to holders as real Bitcoin — every 10 minutes, on block-time. 🐾

The cat is always about to pay you.
This timer never stops. Every time it hits zero, the window's trading fees are claimed in BTC and sent to every holder — then it starts again. No buttons. No claiming. Block-time is the only schedule the cat respects.
Every opcode has a story.
This one has nine lives.
OP_CAT is the oldest inside joke in Bitcoin — an original Satoshi opcode with "CAT" literally in its name, banished in 2010 and memed about ever since. We gave the cat a body.
Satoshi ships a cat
Bitcoin v0.1 launches with OP_CAT baked into Script — opcode 0x7e.
Its job: concatenate two items on the stack into one. The most innocently named
opcode in the whole codebase, living quietly inside Bitcoin from day one.
The cat gets banished
Satoshi quietly disables OP_CAT, worried that stacking CATs could balloon
memory and crash nodes. No funeral. No goodbye. One commit, and the cat was locked
outside the consensus rules — where it sat, staring in through the window, for over a decade.
"Bring back the cat"
Bitcoin devs formally propose resurrecting the opcode — BIP-347, the first
serious push to reactivate OP_CAT via soft fork. Crypto Twitter turns it into
a rallying cry, and the cat becomes the mascot of Bitcoin's next era.
The cat comes back
You can't keep a cat out forever. $OP_CAT is the meme made flesh — a cosmic,
star-dusted, Bitcoin-eyed cat that does what the opcode always promised: it
concatenates you to Bitcoin. Every. Ten. Minutes.
Simple stack. No tricks.
Two items on the stack: the cat, and Bitcoin. OP_CAT concatenates them.
Trading fee, fully recycled
Every trade carries a 4% fee. None of it sits in a treasury black hole — all of it flows back to the people holding the cat.
Paired to Bitcoin
$OP_CAT trades against BTC — not a stablecoin, not chain gas. The cat and the coin, joined on the stack.
Block-time cadence
Payouts every 10 minutes — the same rhythm as a Bitcoin block.
Payouts per day
Around the clock, every day, as long as the chain keeps ticking.
Staking, locks, claims
Nothing to do. Hold the cat, receive the Bitcoin.
Every 10 minutes, the cat pays out.
Bitcoin produces a block roughly every 10 minutes. OP_CAT distributes rewards on the same clock. Here's the full loop, start to finish.
Trades happen
Every buy and sell of $OP_CAT carries a 4% trading fee, collected automatically at the moment of the swap.
Fees accumulate
Collected fees pool up over a 10-minute window — one Bitcoin block-time. No manual triggers, no admin buttons.
Claimed in BTC
At the end of each window, the accumulated fees are claimed and converted into BTC — the only asset the cat's eyes have ever seen.
Sent to holders
The BTC is distributed pro-rata to every holder — your share of supply is your share of the payout, straight to your wallet.
📖 The fine print (the good kind)
The reward engine runs on a fixed cycle: every 10 minutes, all trading fees collected during that window are claimed in BTC and sent to holders pro-rata. If you hold 1% of the eligible supply, you receive 1% of that window's BTC payout.
your_btc_reward = window_fees_in_btc × ( your_balance ÷ eligible_supply )
- Automatic. No claiming, no staking, no dashboards to babysit. Rewards land in your wallet on their own.
- Pro-rata. Payouts scale exactly with your holdings at distribution time. More cat, more Bitcoin.
- Paid in real BTC. Not points, not a reflection of the token itself — Bitcoin.
- Block-time cadence. ~144 payout cycles per day, mirroring Bitcoin's own heartbeat.
- Sell the cat, lose the stream. Only wallets holding $OP_CAT at distribution time are included in that cycle.
