Prerequisites
Git
Node.js (includes
npx)
Installation
Install the CLI, skills, and A2A runtime together:
npx -y @okxweb3/onchainos-installer installInstall the beta channel:
npx -y @okxweb3/onchainos-installer install --betaSkill Workflows
The skills work together in typical DeFi flows:
Search and Buy: okx-dex-market (find token) -> okx-agentic-wallet (check funds + execute trade)
Portfolio Overview: okx-agentic-wallet (holdings) -> okx-dex-market (enrich with analytics + price charts)
Market Research: okx-dex-market (trending/rankings + candles/history) -> okx-agentic-wallet (trade)
Swap and Broadcast: okx-agentic-wallet (get quote -> swap -> broadcast -> track order)
Full Trading Flow: okx-dex-market (search + price/chart) -> okx-agentic-wallet (check balance -> swap -> simulate + broadcast + track)
Leaderboard → Research → Trade: okx-dex-market (top traders by PnL/win rate + token analytics) -> okx-agentic-wallet (execute trade)
Follow Smart Money: okx-dex-market (KOL/smart money buys + token details + holder cluster + price chart) -> okx-agentic-wallet (trade)
Workflows
Pre-built workflow orchestrations in workflows/ compose multiple skills into complete operations. The agent reads workflows/INDEX.md to route requests, then follows the step-by-step instructions in the matched workflow file.
Workflow | What it does | CLI command |
Token Research | Price, security, holders, cluster, smart money signals, optional launchpad deep-dive |
|
Daily Brief | Market pulse + smart money + new token activity + portfolio alerts | — |
Smart Money Signals | SM signal list aggregated by token + per-token due diligence |
|
New Token Screening | MIGRATED launchpad scan + safety & dev enrichment for top 10 |
|
Wallet Analysis | 7d/30d PnL, trading behaviour, recent on-chain activity |
|
Portfolio Check | Balances, total value, 30d PnL overview |
|
Wallet Monitor | In-session polling — alert on new trades from watched wallets | — |
Wallet Monitor (WS) | Background WebSocket session for offline wallet monitoring | — |
Composite CLI commands
Single commands that replace multiple individual tool calls:
# Token report: info + price + advanced-info + security scan (parallel)
onchainos token report --address <addr> --chain solana
# Full workflow commands
onchainos workflow token-research --address <addr> [--chain solana]
onchainos workflow smart-money [--chain solana]
