Atomic Swap Flow
This server handles step 2 of the 5-step atomic swap flow:
kaleidoswap_atomic_init → swapstring + payment_hash (kaleidoswap-mcp)
wdk_atomic_taker → whitelist HTLC on node ← this server
wdk_get_node_info → taker_pubkey ← this server
kaleidoswap_atomic_execute → HTLC settlement (kaleidoswap-mcp)
Installation
npm install
npm run build
