SideSwap

• Name: SideSwap
• URL: https://sideswap.io/
• Category: Liquid wallet-and-swap stack / dealer infrastructure / peg-routing middleware
• Tags: bitcoin-ecosystem
• Summary: SideSwap is Liquid-specific market plumbing. The note earns its keep because walleting, peg flows, swaps, market data, and self-hostable dealer infrastructure sit in one operator-shaped stack. It is not a general Bitcoin exchange primitive.
• What it does:
  • Provides a non-custodial wallet for holding, sending, receiving, and swapping Liquid assets across mobile and desktop platforms
  • Supports peer-to-peer swaps and Liquid peg-in / peg-out flows between BTC and L-BTC
  • Supports AMP security tokens and broader Liquid asset management, including bearer assets, NFTs, and other token types referenced in official materials
  • Publishes a JSON-RPC-over-WebSocket API with market, swap, and peg endpoints for external integrations
  • Maintains open-source client and Rust repositories, including tooling for swap logic, self-hosted dealer bots, and SideSwap Manager infrastructure
  • Frames itself as underlying infrastructure for a bitcoin-based financial system built on Liquid settlement rails
• Key claims:
  • The homepage calls SideSwap the “Settlement infrastructure of the Liquid Network” and says trading is non-custodial, registration free, and peer-to-peer
  • The homepage says users can manage security tokens without intermediaries and describes Liquid as Bitcoin’s financial layer for issuing and trading multiple asset types with confidential transfers
  • The homepage FAQ says SideSwap is “laser focused on building the base infrastructure for a bitcoin based financial system”
  • The API documentation says SideSwap exposes a JSON-RPC v2.0 API over WebSocket at wss://api.sideswap.io/json-rpc-ws and documents peg-in / peg-out, server-parameter subscriptions, and swap-related methods
  • The API docs note that the production server uses Liquid network addresses and asset IDs, reinforcing that the product is tied to operational settlement flows on Liquid rather than only to a demo client
  • The sideswapclient README describes the official application as a cross-platform, non-custodial wallet and atomic swap marketplace for Liquid, written in Flutter with a Rust core and relying on Blockstream GDK for low-level wallet functionality
  • The sideswapclient README highlights atomic swaps, AMP-asset management, confidential non-custodial operation, built-in market data, and pluggable dealer bots with HTTP and WebSocket APIs for automated market making
  • The sideswap_rust README describes self-hosted dealer programs, SideSwap Manager for managing Liquid bitcoin assets, swap-protocol documentation, and the official API reference as core project components
• Whitepaper: No canonical standalone SideSwap whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, API docs, and the public sideswapclient / sideswap_rust repositories; see ../whitepapers/sideswap-primary-sources-2026-05-01.md.

Internal linkages

• Best upward marketplace reads: bisq and robosats.
• Keep the note on stronger P2P market anchors. The Liquid wallet, peg, and dealer stack is the local wrinkle, not a reason to spray across every swap rail.

Control surface

• Read SideSwap as operator-shaped Liquid market plumbing, not as a neutral Bitcoin exchange primitive.

• Practical leverage sits in dealer participation, liquidity visibility, peg routing, client defaults, and how much of the user experience still depends on SideSwap-run infrastructure even when custody stays local.
