Nexus Nodes
Nexus Nodes are self‑hosted maker daemons that supply liquidity to the DotSwap network while retaining full custody of funds.
Publish Curves
• Support CPMM (constant‑product) and CLMM (concentrated range) formats.
• Update depth instantly after each fill to avoid stale quotes.
Sign PSBTs
• Validate inbound PSBT against posted intent (price, size, fee).
• Apply partial signature for owned inputs only; refuse if slippage breached.
• Return signed PSBT to Nexus Engine within SLA window.
• Update local UTXO set and curve after confirmation.
Lifecycle
Boot → Connect to Bitcoin Core & configure wallet keys.
Curve Broadcast → POST initial CPMM/CLMM data.
Quote Loop → Receive PSBT, run risk check, sign, respond.
Settle & Refresh → Detect mined tx, adjust liquidity, publish new curve.
Security Notes
Runs behind Tor or reverse proxy; no private keys leave host.
Supports HSM/MPC signing for institutional setups.
Ideal Operators
Market‑making desks, custody firms, DAOs seeking yield, or advanced individuals who prefer self‑managed liquidity over custodial pools.
