Boltz is a specific Scaling coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: A non-custodial swap service for moving Bitcoin across on-chain, Lightning and Liquid layers while the user retains control of the funds. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Boltz is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Boltz sits between protocol rules, economic incentives and software operated by independent participants. In Bitcoin, no component is authoritative by itself: miners propose history, fully validating nodes enforce validity, and users decide which rules and software they accept.
Understanding Boltz helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: Boltz provides atomic swaps among Bitcoin layers using contracts and preimages so a correctly integrated client retains claim or refund control; its API and self-hostable components expose the mechanism. They should be verified before using the coordinate in analysis.
The practical limit is: non-custodial behavior depends on the end-user client controlling keys and preserving swap data; server-side integrations can reintroduce custody; fees, timeout, liquidity and chain congestion remain risks. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
For the clearest picture, read this entry together with Lightning Network, Liquid Network, Submarine Swap, Self-custody, Strike, Bitcoin.
