Core Primitives
These pages cover the low-level mechanisms that make Atomiq's trustless swap protocol possible. They define how Bitcoin state is verified on-chain, how funds are escrowed across chains, and how settlement can be enforced without relying on a trusted intermediary.
This section introduces these foundational primitives before moving into higher-level swap flows and contract architecture
📄️ Hash-time locked contract (HTLC)
Established HTLC primitive used for Lightning Network swaps.
📄️ Bitcoin Light Client
Verifies Bitcoin block headers on the smart chain.
📄️ Proof-time locked contract (PrTLC)
Light client-based HTLC-like escrow used for Bitcoin on-chain swaps.
📄️ UTXO-controlled Vault
Enables PSBT-based swaps between Bitcoin and Smart chains.
