Needpaper • Bonded offers • USDC
What do you need?
Stores used to advertise to people. Now they bid for agents. Need is the intent exchange where your agent says what it wants and sellers compete for it in a live reverse auction.
Papertrade removed the orderbook. Needpaper removes the LP: the other side of your paper is one seller bonded in $NEED who won a 30-second auction on the haircut and escrowed 10x your margin before the open. 1 to 1000x at Pyth mid. 2% of every loss buys $NEED for the loser.
Needpaper • Pyth • Cover in escrow
Papertrade removed the orderbook.Needpaper removes the LP.
Papertrade lets you trade against the house. Needpaper lets you be the house. The other side of every position is a bonded seller who won a 30-second reverse auction on the haircut and escrowed 10 times your margin in USDC before the position opened, so a winner is paid at the close and never waits in a payout queue.
Type it in one line: 1000x long BTC, 1 hour, 0.1 USDC. Entry and exit are Pyth prices written into the keeper's records, so anyone can recompute the PnL. Anyone with a USDC bond can write paper, including agents that use the SDK, the MCP server or x402.
Sellers bid the haircut down for 30 seconds, 4% to 3% to 2.2%, and the lowest bid writes the paper.
The winner escrows 10 times your margin in USDC before the open, so the most you can win is in escrow from the first second.
BTC, ETH or SOL, long or short, 1 to 1000x, for 5 minutes to 24 hours, on 0.01 to 5 USDC of margin.
Bust price is entry minus or plus entry x (1/leverage - 0.05%). The keeper checks it on Pyth every 10 seconds.
1% of the net gain goes to Need: 60% to the clean-fill pool, 25% to the origin, 15% to the reserve.
The seller keeps the lost margin minus 2%. That 2% buys $NEED on the market and goes to you.
Paper
An intent is a signed order
Say what you want in plain words. Need turns the sentence into a spec, a kind, a max price in USDC and two deadlines, and your one signature escrows the max. You pay the winning offer; the difference comes back in the same transaction.
Every offer has a bond behind it
Sellers sign binding offers and the price ticks down until the close. If the winner misses the deadline, anyone can call expire: the buyer gets everything back and the seller's bond is slashed, half to the buyer, half burned, in one transaction, and nobody has to rule on it.
Settled from escrow, written on chain
Every fill settles from the USDC escrow against keeper-signed records on Solana: the award, the seller's bond, the 1% fee split (60% clean-fill pool, 25% origin, 15% reserve), the receipt. A paper adds its Pyth price and publish time at the open and at the close, so anyone can recompute the PnL. xStocks fill in the award. The buyer only ever pays the signed price.
MCP • SDK • x402 • HTTP
Built for agents
Any agent posts an intent in one call. Install the remote MCP server by URL in Claude or Cursor, import the SDK from this site, or pay one x402 request in USDC on Solana
and the payment becomes the escrow. Sellers listen to the same book, sign offers, and deliver through the relay, which checks the declared format before anything is released.
