Maker
Makers run Nexus Nodes, supplying self‑custodial liquidity to the DotSwap network.
Publish Curves
Advertise CPMM or CLMM price curves through the Nexus liquidity API (endpoint TBD). Curves update automatically after every fill.
Liquidity Custody
Funds stay in the Maker’s multisig wallet until a swap PSBT is partially signed—no pre‑deposit required.
PSBT Validation & Signing
Receive PSBT drafts from Nexus Engine, ensure parameters match posted intent (price, size, fee). Sign owned inputs and return signature within SLA.
State Refresh
Monitor block confirmations, update local UTXO set, and re‑publish curve depth post‑trade.
Risk Controls
Enforce min/max size, slippage caps, and fee floors before signing to prevent toxic flow.
Typical Workflow
Boot Node → Connect to Bitcoin Core, load wallet keys.
Curve Broadcast → Push initial CPMM/CLMM liquidity parameters.
Quote & Sign → Validate inbound PSBT, add signature, respond to Engine.
Settle & Update → Detect mined tx; adjust reserves; republish curve.
Ideal Operators
Professional market‑making desks seeking yield on idle BTC.
Custody platforms offering on‑chain liquidity services.
DAOs or treasuries wanting deterministic exit/entry pricing.
Running a Nexus Node lets Makers earn swap fees without surrendering custody, while strengthening overall liquidity depth for Bitcoin‑native assets.
