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 calls
• api_key — when server-side API key auth is enabled, send as HTTP header x-antalpha-agent-api-key on 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:

1. Check if ~/.smart-money/agent.json exists
2. If not, call antalpha-register, save both agent_id and api_key
3. Use agent_id for all MCP calls; include api_key as header if auth is enabled

MCP Tools (6)

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). Each call auto-refreshes the public pool (scan-if-stale) and backfills your custom addresses, so signals stay current without a separate scan call.

Parameters:

• agent_id (required): Your agent ID
• level (optional): high / medium / low / info / all (default: all; all excludes silent info events)
• 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. Works for any address: monitored wallets (public pool / your custom list) return persisted, baselined signals; un-monitored addresses fall back to a read-only on-chain snapshot (first-position / accumulation meta unavailable without a baseline).

Parameters:

• agent_id (required): Your agent ID
• address (required): Ethereum address (0x...)
• limit (optional): 1-50 (default: 10)
• chain_id (optional): chain for the snapshot path when the address is not monitored (default: ETH mainnet)

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 ID
• action (required): add / remove / list
• address (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-fills stream_id
• remove: decrements RC; cancels subscription only when last reference is released
• list: returns all custom addresses with stream_id and status

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 ID
• address (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-signal { agent_id }     ← auto-triggers a fresh scan, then returns current results
3. ⚠️  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-signal { agent_id }   ← auto-triggers first scan + baseline
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_OK when 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 add succeeds — 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)

1. Call smart-money-custom { action: "add", ... } — on-chain subscription auto-registered
2. Call smart-money-signal immediately — auto-triggers a fresh scan and returns the baseline
3. ⚠️ 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
4. Execute openclaw cron add with 15-min interval and --session isolated
5. Confirm: address added, stream_id, Cron job name and schedule
6. 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"

1. Call smart-money-custom { action: "remove", address: "0x..." } — on-chain subscription auto-cancelled
2. Update or cancel the associated Cron job
3. Confirm: "Monitoring stopped. On-chain subscription cancelled."

On "List my custom addresses" / "查看我的自定义监控"

1. Call smart-money-custom { action: "list" }
2. Show: address, label, stream_id (active/inactive), added_at
3. Show remaining slots: 5 - current_count

On session start (if monitoring is enabled)

1. Read ~/.smart-money/monitor-state.json
2. If monitoring: true and now - last_check > interval:
• Run scan + signal check silently
• Only speak up if new signals found
• Update last_check

Changelog

v1.2.3 (2026-06-18)

• Aligned with live MCP (origin/main): confirmed the 5-tool surface (smart-money-signal, smart-money-watch, smart-money-list, smart-money-custom, smart-money-pool) plus antalpha-register; smart-money-scan stays removed (its on-demand private-wallet scan is auto-backfilled when smart-money-signal triggers a stale public scan).
• Changed: smart-money-signal level now documents the info tier (high/medium/low/info/all); all still excludes silent info events.
• Changed: smart-money-watch now works for any address — un-monitored addresses return a read-only on-chain snapshot (no baseline → first-position/accumulation meta suppressed); added optional chain_id param.

v1.2.2 (2026-06-15)

• Fixed: removed the decommissioned smart-money-scan tool — it no longer exists on the live MCP (tools/list), so workflows that called it failed at the "first scan / baseline" step. Tool count 7 → 6.
• Changed: the on-demand scan it performed is now folded into smart-money-signal, which auto-refreshes the public pool (scan-if-stale) and backfills custom addresses on every call. Workflows now call smart-money-signal directly for the baseline.

v1.2.1 (2026-04-17)

• New: Agent auto-creates Cron after smart-money-custom action=add (no user prompt needed)
• New: Strong-nudge copy (EN + ZH): "you will NEVER be alerted without Cron"
• New: Recommended interval 15 min, --session isolated; agent executes without extra confirm
• Improved: Agent Behavior Rules — add flow creates Cron immediately, optional only on explicit refusal

v1.2.0 (2026-04-17)

• New: smart-money-custom upgraded — add/remove/list with on-chain subscription auto-management
• New: Reference Counting (RC) — same address across multiple agents shares ONE subscription stream
• New: sm_stream_registry global address→stream registry table
• New: agent_watched_wallets per-agent custom watchlist table
• New: smart-money-signal merges public pool + agent custom addresses (two-path query)
• Improved: smart-money-custom action=list returns stream_id + added_at

v1.1.0 (2026-04-14)

• New: smart-money-pool tool — query whale LP add/remove activity on Uniswap V2/V3
• New: smart-money-signal extended with POOL_IN / POOL_OUT signal types
• New: Real-time on-chain event stream integration for LP event ingestion

v1.0.2

• Added auto-monitoring setup guide and agent behavior rules

v1.0.1

• Various bugfixes, address normalization, README rewrite

v1.0.0 (2026-03-28)

• Initial release

Security Notes

• Agent identity via UUID — no private keys involved
• api_key is secret; store securely, never expose in logs or prompts
• Custom watchlist addresses are isolated per agent_id (multi-tenant)
• On-chain subscription cancelled automatically on remove (no zombie subscriptions)
• All data comes from public blockchain; no user funds are touched
