Wallet Monitor Skill

You are helping the user manage their wallet monitoring setup. This skill tracks on-chain activity for watched wallets using Alchemy Enhanced APIs, detecting transfers, swaps, and large trades on Ethereum Mainnet and Base.

The wallet monitor runs as a separate microservice at http://127.0.0.1:9100. Use the local_rpc tool to call its RPC endpoints directly.

API Endpoints

All endpoints are on the wallet-monitor-service at http://127.0.0.1:9100.

1. Watchlist Management

List all watched wallets:

local_rpc(url="http://127.0.0.1:9100/rpc/watchlist/list")

Add a wallet:

local_rpc(url="http://127.0.0.1:9100/rpc/watchlist/add", method="POST", body={
  "address": "0x...",
  "label": "Whale Alpha",
  "chain": "mainnet",
  "threshold_usd": 50000
})

• address (required): 0x + 40 hex chars
• label (optional): human-readable name
• chain (optional): "mainnet" or "base" (default: "mainnet")
• threshold_usd (optional): large trade threshold in USD (default: 1000)

Remove a wallet:

local_rpc(url="http://127.0.0.1:9100/rpc/watchlist/remove", method="POST", body={"id": 1})

Update a wallet:

local_rpc(url="http://127.0.0.1:9100/rpc/watchlist/update", method="POST", body={
  "id": 1,
  "label": "New Label",
  "threshold_usd": 10000,
  "monitor_enabled": true,
  "notes": "Interesting trader"
})

2. Activity Queries

Query recent activity:

local_rpc(url="http://127.0.0.1:9100/rpc/activity/query", method="POST", body={
  "limit": 25
})

Large trades only:

local_rpc(url="http://127.0.0.1:9100/rpc/activity/query", method="POST", body={
  "large_only": true,
  "limit": 25
})

Filter by address/chain/type:

local_rpc(url="http://127.0.0.1:9100/rpc/activity/query", method="POST", body={
  "address": "0x...",
  "chain": "mainnet",
  "activity_type": "swap",
  "limit": 50
})

Filter fields (all optional): address, chain, activity_type (eth_transfer, erc20_transfer, swap, internal), large_only (bool), limit (int).

Activity statistics:

local_rpc(url="http://127.0.0.1:9100/rpc/activity/stats")

3. Service Control

Check service status:

local_rpc(url="http://127.0.0.1:9100/rpc/status")

Workflow

1. First check status: local_rpc(url="http://127.0.0.1:9100/rpc/status")
2. Add wallets: local_rpc(url="http://127.0.0.1:9100/rpc/watchlist/add", method="POST", body={...})
3. The background worker automatically polls every 60 seconds
4. Query activity: local_rpc(url="http://127.0.0.1:9100/rpc/activity/query", method="POST", body={"limit": 25})

Important Notes

• The wallet monitor runs as a standalone service (wallet-monitor-service)
• Dashboard available at http://127.0.0.1:9100/
• Supported chains: "mainnet" (Ethereum) and "base" (Base)
• Each wallet has its own threshold_usd for large trade detection (default $1,000)
• Swap detection: transactions with both outgoing and incoming ERC-20 transfers are classified as swaps
• USD values are estimated using DexScreener price data (cached 60s)
• The worker uses block-number cursors for gap-free incremental polling
• All responses are wrapped in {"success": true, "data": ...} or {"success": false, "error": "..."}
