ATOMIC SWAP

Design Philosophy

Atomic swaps enable peer-to-peer exchanges of crypto tokens across different blockchain networks, executing only if both parties deposit a predetermined amount of tokens to the exchange contract. This enables any two users to swap digital tokens without relying on a third party to facilitate the transaction—thereby reducing counterparty risks. Atomic swaps either receive the necessary token deposits from each user and perform the swap or return all deposited tokens to their original owner.

Architecture

Atomic Book: Atomic Book is a decentralized order book system built on atomic swaps, enabling users to trade in a manner close to a centralized exchange experience.

Matching Engine: Matching Engine maintains system logic to identify and execute matching orders in the Atomic Book, triggering atomic swaps when compatible orders are found. The Matching Engine supports order splitting, merging, and partial trading to enable fast order execution.

Routing Market: Routing Market is a market-making system that allows various market makers to fulfill swap requests; it can even integrate with external AMMs to provide liquidity.

Innovations

Technical Innovation

The protocol integrates Hash Time-Locked Contracts (HTLC) with adapter signatures to enable secure and trustless atomic swaps. To enhance cross-chain privacy and security, zero-knowledge proofs are employed throughout the transaction process. A key breakthrough is the implementation of a discrete logarithm equivalence proof between the secp256k1 and ed25519 elliptic curves, ensuring cryptographic key consistency and addressing the long-standing challenge of interoperability across heterogeneous blockchain architectures.

Positioning Innovation

Satoshion is not merely a trading platform, but a foundational protocol layer designed to serve as a core secure infrastructure within the multi-chain DeFi ecosystem. By focusing on protocol-level interoperability, it aims to enable seamless, trustless asset exchange across heterogeneous chains.

Ecosystem Innovation

Satoshion envisions a borderless blockchain future—where users can seamlessly acquire any asset, on any chain, from anywhere. By serving as a foundational layer for cross-chain DeFi infrastructure, the protocol enables permissionless access to a wide range of assets, including cryptocurrencies, real-world assets (RWA), and even tokenized stocks, thereby unlocking unprecedented liquidity and accessibility in decentralized finance.
