Open liquidity for Bitcoin and Runes — settled on the only chain that ever mattered. You hold the keys. You run the pool. The network does the rest.
When every holder can become a market maker, liquidity stops being a privilege.
When every community runs its own market, the world becomes a network of free economies.
On Bitcoin L1. Sovereign. Auditable. Forever.
This isn't another L2 wrapper or a cross-chain bridge. It's pure Bitcoin — final settlement, atomic swaps, runes, and self-custody — with the infrastructure people actually need to participate.
No sidechains. No multisig federations. No wrapped tokens. Every swap is a real Bitcoin transaction settled on mainnet by miners. PSBTs, Taproot, Runestones — the protocol as it was meant to be used.
Your private key never leaves your machine. The pool runs on a small open-source daemon you operate yourself. Kray Space is a router — we cannot move your funds even if we wanted to.
Runes have real communities — fair launches, no insider allocations, culture before capital. Each community can host its own liquidity. No gatekeepers. No listing fees. No KYC.
Here's exactly what happens when someone trades against your pool. Kray Space cannot lie, cannot front-run, cannot drain — every party verifies the same immutable rules independently.
Someone clicks BUY on /swap. Kray Space builds an unsigned PSBT and forwards it to your daemon over WebSocket.
Your daemon ignores what the server claims and fetches actual reserves directly from mempool.space + ordinals.com.
~25 immutable rules: AMM math, fee caps, sighash flags, Runestone integrity. If any fail, the daemon refuses. Your key never leaves the box.
Kray Space re-applies the same rules to the daemon's signed PSBT. Even a hostile daemon would be caught here — buyer is always protected.
Buyer's wallet adds their signature. A final phantom-signature check runs. Then the transaction broadcasts to the Bitcoin mempool — atomic, final, irreversible.
We didn't invent a new trust model. We engineered defenses against every historical Bitcoin / PSBT / Runes exploit. Then we wrote a runnable test suite that hammers the system with 25 of them.

Most “DeFi on Bitcoin” today wraps your coins, hands keys to a federation, or routes through synthetic L2s. Kray's user-pool architecture does none of that.
