How Blowup works

Every X, TikTok and Instagram account can have a market. A market trades keys — positions on a bonding curve tied to that account. Anyone can be listed. Only the account owner can claim.

Keys are not securities, not shares, and not a claim on anybody's income. Their price is set purely by the curve: more keys outstanding, higher the price of the next one.

Blowup uses a sum-of-squares curve. The price of key number n is n² / 16000 ETH. The first key is nearly free; the 10th costs 0.00625 ETH; the 50th costs about 0.156 ETH. Buying walks up the staircase, selling walks back down it. The ETH paid in sits in the contract as reserve, so there is always liquidity to sell into.

Every buy and sell pays a 7% fee on the curve price, split three ways:

• 3.0% to the account owner. Accrues from the very first trade and sits in escrow whether or not they ever show up. Claimable forever.
• 2.5% to current keyholders. Distributed pro-rata to everyone holding keys at the moment of the trade — hold a key, earn a cut of every trade after yours.
• 1.5% to the protocol.

If you own a listed account, prove it (bio code or a signed post) and your wallet is registered on-chain as the subject owner. From then on you can withdraw your escrowed 3% at any time. Nothing about trading changes — claiming just unlocks your side of the fees.

Blowup settles in ETH on Robinhood Chain, an Arbitrum Nitro L2 (chain ID 4663; testnet 46630). The protocol is a single non-upgradeable contract; every trade, escrow accrual and reward payout is an on-chain event anyone can verify.

Prices move on a curve with no market maker and no floor beyond the reserve. You can lose everything you put in. Nothing here is investment advice; trade for fun, with money you can afford to lose.
