nansen alerts list --table
nansen alerts create --name <name> --type <type> --chains <chains> --telegram <chatId>
nansen alerts update <id> [--name <name>] [--chains <chains>]
nansen alerts toggle <id> --enabled|--disabled

Alert Types

1. sm-token-flows — Smart Money Token Flows

Track aggregated SM inflow/outflow. At least one flow threshold should be specified.

Type-specific flags:

• --inflow-1h-min/max, --inflow-1d-min/max, --inflow-7d-min/max (USD thresholds)
• --outflow-1h-min/max, --outflow-1d-min/max, --outflow-7d-min/max
• --netflow-1h-min/max, --netflow-1d-min/max, --netflow-7d-min/max
• --token (repeatable) — include specific tokens
• --exclude-token (repeatable)
• --token-sector / --exclude-token-sector (repeatable)
• --token-age-max
• --market-cap-min/max , --fdv-min/max

Example:

nansen alerts create \
  --name 'SM ETH Inflow >5M' \
  --type sm-token-flows \
  --chains ethereum \
  --telegram 5238612255 \
  --inflow-1h-min 5000000 \
  --token 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2:ethereum

2. common-token-transfer — Token Transfer Events

Track real-time transfer events matching specified criteria.

Subject types: address, entity, label, custom-label

Format: --subject type:value (e.g. --subject label:"Centralized Exchange")

Type-specific flags:

• --events (comma-separated)
• --usd-min/max , --token-amount-min/max
• --subject (repeatable) — addresses/entities/labels to track
• --counterparty (repeatable) — requires --subject
• --token / --exclude-token (repeatable)
• --token-sector / --exclude-token-sector (repeatable)
• --token-age-min/max , --market-cap-min/max
• --exclude-from / --exclude-to (repeatable)

Event direction notes:

• buy for counterparties = sell for subjects
• send for counterparties = receive for subjects
• To track "any address sending to CEX": use --subject with receive, not --counterparty with send

Example:

nansen alerts create \
  --name 'Large USDC Transfers' \
  --type common-token-transfer \
  --chains ethereum \
  --telegram 123456789 \
  --events send,receive \
  --usd-min 1000000 \
  --token 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48:ethereum

3. smart-contract-call — Smart Contract Interactions

Track contract calls matching specified criteria.

Type-specific flags:

• --usd-min/max
• --signature-hash (repeatable, e.g. 0x095ea7b3 for approve)
• --caller / --exclude-caller (repeatable)
• --contract / --exclude-contract (repeatable)

Example:

nansen alerts create \
  --name 'Uniswap V3 Large Swaps' \
  --type smart-contract-call \
  --chains ethereum \
  --telegram 123456789 \
  --usd-min 1000000 \
  --contract entity:"Uniswap V3"

Notes

• Chain aliases: Hyperliquid = hyperevm, BSC = bnb.
• Multiple channels can be combined: --telegram 123 --slack https://... --webhook https://...
• --webhook sends a POST request with the alert payload to any HTTP/HTTPS endpoint. Useful for server deployments, Zapier, n8n, or custom integrations. The endpoint must be publicly reachable and return a 2xx response.
• --data '' merges raw JSON on top of named flags (escape hatch for fields without named flags).
• Alert endpoints are internal-only. Non-internal users receive 404.
• Use single quotes for names with $ or special characters: --name 'SM >$1M'
