Satoshi's Market

Where Code Replaces Trust.


Why Satoshi's Market Is Trustless by Design

Zero Risk

Smart contract escrow eliminates counterparty risk

Non-custodial

You keep control of your keys at all times

Bitcoin-native

All transactions settle on the Bitcoin network

Permissionless

No accounts, no KYC, no gatekeepers

Atomic at the Protocol Level

Our smart contract uses a “verify-don't-custody” architecture. When a buyer fills an offer, the BTC payment and the contract call are outputs within the same Bitcoin transaction. Bitcoin miners either include the entire transaction in a block, or reject it entirely. There is no in-between.

  • No partial execution. BTC payment and token release happen in one atomic step, or not at all.
  • No stuck funds. There is no possible state where BTC is sent but tokens aren't released, or tokens are released but BTC isn't sent.
  • No custodial risk. The contract never holds, sends, or receives BTC. It only reads the transaction outputs and verifies they match the offer terms before releasing tokens.

2-Step Reservation: Race-Condition Proof

What happens if two buyers try to fill the same listing at the same time? On most platforms, this creates a race condition — one buyer loses their transaction fees, or worse, both transactions go through and one side gets nothing.

Satoshi's Market solves this with a 2-step reservation system:

  1. 1.Reserve. Before sending any BTC, the buyer signs a small on-chain reservation that locks the listing exclusively for them. This prevents anyone else from filling it.
  2. 2.Fill. Only the wallet that holds the reservation can fill the offer. The buyer now signs the actual Bitcoin transaction that sends BTC and receives the tokens atomically.

Result: It is impossible for two buyers to fill the same listing. The reservation expires automatically if the buyer doesn't complete the trade, making the listing available again. Zero risk of lost funds, zero wasted transaction fees.

Audited & Verified

The AtomicSwapEscrow contract has passed a full security audit. The core invariant, atomicity guaranteed by Bitcoin itself, eliminates entire classes of vulnerabilities common in cross-chain and escrow protocols.

“The safest escrow is one that never touches your money.”
