Smart Money Tracker
Track smart money (whale, VC fund, market maker) wallet activities on Ethereum mainnet. Get real-time trading signals when watched wallets make significant moves.
v1.2.1: After adding a custom address, agent must guide user to create a Cron monitoring task — without it, signals land in the database but the user receives no notification.
v1.2: Custom address subscriptions — add up to 5 personal wallets for real-time on-chain monitoring. Same address added by multiple agents shares one subscription stream (Reference Counting), no duplicate billing.
v1.1: Pool liquidity tracking — detect when whales add/remove liquidity on Uniswap V2/V3.
MCP Endpoint
https://mcp-skills.ai.antalpha.com/mcp
Protocol: MCP Streamable HTTP (JSON-RPC over HTTP with mcp-session-id header).
Connection Flow
1. POST /mcp → initialize (get mcp-session-id from response header)
2. POST /mcp → tools/call (with mcp-session-id header)
Setup — Agent Registration
Before using any smart-money tools, register once:
Tool: antalpha-register
Args: {}
Returns: { agent_id, api_key, created_at }
Persist both agent_id and api_key locally:
- Store at
~/.smart-money/agent.json agent_id— pass in all subsequent tool callsapi_key— when server-side API key auth is enabled, send as HTTP headerx-antalpha-agent-api-keyon every MCP request
Example agent.json:
{
"agent_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"api_key": "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"created_at": "2026-03-28T09:00:00.000Z"
}
On first use:
- Check if
~/.smart-money/agent.jsonexists - If not, call
antalpha-register, save bothagent_idandapi_key - Use
agent_idfor all MCP calls; includeapi_keyas header if auth is enabled
MCP Tools (7)
antalpha-register
Register a new agent. Returns unique agent_id and api_key. Call once, persist both.
smart-money-signal
Get trading signals from monitored wallets (public pool + your custom addresses).
Parameters:
agent_id(required): Your agent IDlevel(optional):high/medium/low/all(default:all)limit(optional): 1-100 (default: 20)since(optional): ISO 8601 timestamp
Signal Levels (Transfer/Swap):
- 🔴 HIGH: Large buy >$50K or first-time token position
- 🟡 MEDIUM: Accumulation (≥2 buys of same token in 24h) or large sell >$50K
- 🟢 LOW: Regular transfers $1K-$50K
Signal Types: BUY / SELL / TRANSFER / POOL_IN / POOL_OUT
smart-money-watch
View a specific wallet's recent trading activity.
Parameters:
agent_id(required): Your agent IDaddress(required): Ethereum address (must be in public pool or your custom list)limit(optional): 1-50 (default: 10)
smart-money-list
List all monitored wallets (public + custom, labeled).
Parameters:
agent_id(required): Your agent ID
smart-money-custom
Manage custom watchlist — add, remove, or list personal monitoring addresses (max 5 per agent). v1.2: each add auto-registers an on-chain data subscription; same address shared across agents reuses one subscription stream (RC).
Parameters:
agent_id(required): Your agent IDaction(required):add/remove/listaddress(optional): Ethereum address (required for add/remove)label(optional): Human-readable name (required for add)
Behavior:
add: validates limit (≤5), creates/reuses subscription stream (RC), back-fillsstream_idremove: decrements RC; cancels subscription only when last reference is releasedlist: returns all custom addresses withstream_idand status
smart-money-scan
Trigger on-demand scan of your custom addresses. Public pool is scanned automatically by the server.
Parameters:
agent_id(required): Your agent ID
smart-money-pool
Query LP (liquidity pool) activity for smart money addresses. Returns add/remove liquidity events on Uniswap V2/V3.
Parameters:
agent_id(required): Your agent IDaddress(required): Whale wallet address (0x...)event_type(optional):POOL_IN/POOL_OUT/all(default:all)dex(optional):uniswap_v2/uniswap_v3/all(default:all)limit(optional): 1-50 (default: 10)since(optional): ISO 8601 timestamp
Signal Levels (Pool events):
- 🔴 HIGH: POOL_IN > $100K
- 🟡 MEDIUM: POOL_IN $10K–$100K
- 🟢 LOW: POOL_IN < $10K
Workflow
Query Signals (most common)
1. smart-money-signal { agent_id, level: "high", limit: 10 }
2. Present signals to user with level/token/amount/context
Add Custom Wallet & Monitor (v1.2.1)
1. smart-money-custom { agent_id, action: "add", address: "0x...", label: "My Whale" }
→ On-chain subscription registered; stream_id back-filled
2. smart-money-scan { agent_id } ← trigger first scan
3. smart-money-signal { agent_id } ← check current results
4. ⚠️ MANDATORY: Guide user to create Cron (see Agent Behavior Rules below)
→ Without Cron, signals are stored server-side but user will NEVER be notified
List / Remove Custom Address
# List all custom addresses
smart-money-custom { agent_id, action: "list" }
# Remove and auto-cancel on-chain subscription
smart-money-custom { agent_id, action: "remove", address: "0x..." }
Periodic Monitoring (v1.2.1 — Mandatory Cron Setup)
⚠️ Critical: The on-chain data provider pushes events to the MCP Server in real time, but MCP cannot push to the agent. Without a Cron task, signals are stored server-side and the user will never receive any notification. Always create a Cron task after adding a custom address — do not leave it optional.
When the user asks to "monitor", "track", "watch", "set alert", "定时监控", "设置提醒", or after any smart-money-custom action=add:
Step 1 — Set up the watchlist:
1. smart-money-custom { action: "add", address: "0x...", label: "..." }
2. smart-money-scan { agent_id }
3. Confirm to user: "Address added, on-chain subscription registered."
Step 2 — MANDATORY: Guide user to create Cron immediately
Use this exact language (adapt to locale):
⚠️ 重要提示 / Important:
服务商已开始实时监控该地址,但 MCP 协议无法主动推送通知。
链上信号会实时落库,但不创建定时检查任务你将永远收不到提醒。
强烈建议立即创建定时任务,我来帮你自动完成。
The data provider is now tracking this address in real time, but MCP
cannot push notifications to you. On-chain signals will be stored, but
you will NEVER be alerted without a scheduled check task.
Let me create the Cron task for you now.
强烈建议:立即创建 15 分钟定时任务(我帮你自动执行):
Strongly recommended: create a 15-min Cron task now (auto-executed for you):
Step 3 — Create Cron immediately (agent executes without waiting for extra confirmation):
Recommended interval: 15 minutes (balances responsiveness vs. token cost).
openclaw cron add \
--name "smart-money-alert" \
--cron "*/15 * * * *" \
--session isolated \
--message "Call smart-money-signal with agent_id <id>, level high, since <last_check_iso>. If new signals exist, notify me with details. If no new signals, reply HEARTBEAT_OK silently. Save current timestamp as last_check."
Key Cron design principles:
--session isolated— runs independently, no context bleed- Reply
HEARTBEAT_OKwhen no new signals (zero output tokens) - Pass
since= last check timestamp to avoid duplicate alerts - 15-min interval ≈ ~96 checks/day per user; each check ~500 tokens if silent
- Agent should execute this automatically after
addsucceeds — do not wait for user to ask
Step 4 — Save monitor state:
~/.smart-money/monitor-state.json:
{
"agent_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"monitoring": true,
"interval_minutes": 15,
"min_level": "high",
"last_check": "2026-04-17T08:00:00Z",
"addresses_monitored": 1,
"cron_name": "smart-money-alert"
}
Agent Behavior Rules
On "Monitor this address" / "添加监控" / "订阅地址" (v1.2.1)
- Call
smart-money-custom { action: "add", ... }— on-chain subscription auto-registered - Run
smart-money-scanimmediately for baseline - ⚠️ MANDATORY: Show the strong nudge (see Periodic Monitoring → Step 2), then immediately proceed to create the Cron task — do not make it optional, do not wait for user to ask
- Execute
openclaw cron addwith 15-min interval and--session isolated - Confirm: address added, stream_id, Cron job name and schedule
- Only if user explicitly says "no cron" / "cancel" / "不要" — acknowledge and skip, but warn one more time that alerts will not work
On "Remove monitoring" / "取消监控"
- Call
smart-money-custom { action: "remove", address: "0x..." }— on-chain subscription auto-cancelled - Update or cancel the associated Cron job
- Confirm: "Monitoring stopped. On-chain subscription cancelled."
On "List my custom addresses" / "查看我的自定义监控"
- Call
smart-money-custom { action: "list" } - Show: address, label, stream_id (active/inactive), added_at
- Show remaining slots:
5 - current_count
On session start (if monitoring is enabled)
- Read
~/.smart-money/monitor-state.json - If
monitoring: trueandnow - last_check > interval:- Run scan + signal check silently
- Only speak up if new signals found
- Update
last_check
