Onchain OS DEX WebSocket — Unified Skill

Two ways to consume real-time DEX data:

1. CLI (onchainos ws) — start a background session, poll events incrementally. Best for monitoring and agent-driven workflows.
2. Script — write a custom WebSocket client in Python/Node/Rust. Best for bots and custom logic.

Pre-flight Checks

Read ../okx-agentic-wallet/_shared/preflight.md. If that file does not exist, read _shared/preflight.md instead.

Prerequisites

This skill requires co-installation with okx-dex-market, okx-dex-token, okx-dex-signal, and okx-dex-trenches (all included in the onchainos-skills repository).

Approach 1: CLI (onchainos ws)

Discover Channels

onchainos ws channels                          # list all 9 supported channels
onchainos ws channel-info --channel <name>     # detailed info + example for a channel

Start / Poll / Stop

onchainos ws start --channel <channel> [params]   # start background session
onchainos ws poll --id <ID> [--channel <ch>]       # pull new events
onchainos ws list                                  # list sessions
onchainos ws stop [--id <ID>]                      # stop session(s)

Channel Quick Reference

Channel	Group	Pattern	Required Params
kol_smartmoney-tracker-activity	signal	global	(none)
address-tracker-activity	signal	per-wallet	--wallet-addresses
dex-market-new-signal-openapi	signal	per-chain	--chain-index
price	market	per-token	--token-pair
dex-token-candle{period}	market	per-token	--token-pair
price-info	token	per-token	--token-pair
trades	token	per-token	--token-pair
dex-market-memepump-new-token-openapi	trenches	per-chain	--chain-index
dex-market-memepump-update-metrics-openapi	trenches	per-chain	--chain-index

Parameter Formats

• --token-pair: chainIndex:tokenContractAddress (e.g. 1:0xdac17f958d2ee523a2206206994597c13d831ec7)
• --chain-index: comma-separated chain IDs (e.g. 1,501,56)
• --wallet-addresses: comma-separated addresses, max 200
• --idle-timeout: auto-stop if no poll within this duration (default 30m; 1h, 2h, 300s, 0 to disable)

Examples

# Smart money trade feed
onchainos ws start --channel kol_smartmoney-tracker-activity

# Track specific wallets
onchainos ws start --channel address-tracker-activity --wallet-addresses 0xAAA,0xBBB

# Token price monitoring
onchainos ws start --channel price --token-pair 1:0xdac17f958d2ee523a2206206994597c13d831ec7

# Buy signal alerts on Ethereum + Solana
onchainos ws start --channel dex-market-new-signal-openapi --chain-index 1,501

# New meme token launches on Solana
onchainos ws start --channel dex-market-memepump-new-token-openapi --chain-index 501

# K-line 1-minute candles
onchainos ws start --channel dex-token-candle1m --token-pair 1:0xdac17f958d2ee523a2206206994597c13d831ec7

Poll Filters (tracker channels only)

When polling kol_smartmoney-tracker-activity or address-tracker-activity, these filters are available:

• --min-quote-amount, --min-market-cap, --min-pnl
• --trader (wallet address prefix match)
• --tag (smart_money or kol)
• --trade-type (buy or sell)
• --since (ms timestamp)

Approach 2: Custom Script

When the user wants to build a custom WebSocket client with their own logic, read the corresponding protocol reference file:

Market Data (price & candlestick streams)

Read: ../okx-dex-market/references/ws-protocol.md

Channels: price, dex-token-candle{period}

Token Data (detailed token streams)

Read: ../okx-dex-token/references/ws-protocol.md

Channels: price-info, trades

Signal & Wallet Tracking

Read: ../okx-dex-signal/references/ws-protocol.md

Channels: dex-market-new-signal-openapi, kol_smartmoney-tracker-activity, address-tracker-activity

Meme/Trenches

Read: ../okx-dex-trenches/references/ws-protocol.md

Channels: dex-market-memepump-new-token-openapi, dex-market-memepump-update-metrics-openapi

Common Protocol (all channels share)
