Terminal vs Nansen and Arkham alerts
This page compares the alerts in Nansen and Arkham with Terminal. Competitor facts were checked on October 23, 2026. The Terminal column was checked against the product on October 29, 2026, and again on October 30, 2026. A cell marked Coming waits for a later release.
"Not found" means no page opened for this check said so. It does not prove the feature is missing.
Information only. This is not investment advice. Past alerts record what the price did. They do not predict what it will do.
Who it fits
Nansen and Arkham fit a person who follows money on the blockchain. Their alerts watch wallets, labeled entities, token transfers, and contract calls. The question they answer is who moved what, and where it went.
The Terminal launch offer fits a person in the United States who watches a short list of coins and wants an alert on the market itself: a price level, a percent move, a volume spike, or a move that is unusual for that coin. Alerts can come with a short note on what changed, and each keeps a stored price afterward. Terminal does not watch wallets or transfers.
The two answer different questions. Someone who follows wallets in Nansen or Arkham can keep doing that and still use a separate market alert for the receipt. This page does not tell that person to switch.
Feature table
- Price. Nansen: Pro is $49 a month billed yearly, or $69 billed monthly (credits page). Arkham: A consumer price was not found. A third-party listing says API plans "start at $900/mo" (third-party listing). Terminal launch offer: Free is $0: 3 alerts, 10 coins, checks about every 5 minutes, 10 why-notes a month, 7-day receipts. No card. Trader is $15 a month or $144 a year: 50 alerts, 100 coins, checks about every minute. Pro is $29 a month or $288 a year: 200 alerts, checks about every 15 seconds. Community is $49 a month, monthly only. These prices match the pricing page. Paid plans are not open yet.
- What can trigger an alert. Nansen: Token transfers, flows from wallets Nansen labels, contract calls, and Hyperliquid positions (Smart Alerts page). Arkham: Transfers to or from entities or addresses, set by USD value or token value (alerts announcement). Terminal launch offer: Price above, price below, percent move, volume spike, and unusual move. Funding rate and open interest on Trader, Pro, and Community. You can type a sentence. The builder restates the rule, and you save the fields. No wallet, address, or transfer alerts.
- Delivery. Nansen: Telegram, Slack, Discord, and webhook, as listed in the check next to the Smart Alerts page. Arkham: Email and Telegram, from a search summary of the alerts guide. The page itself did not open. A Telegram mini-app is on its own page (mini-app announcement). Terminal launch offer: A phone alert (a browser notification), Discord, and email. Pro also posts alerts to one Discord server you run. Community posts to up to 10. Coming: Telegram and signed webhooks.
- Why the price moved. Nansen: A note on the alert was not found (Smart Alerts page). A separate AI agent answers questions for 200 or 750 credits (credits page). Arkham: Not found (alerts announcement). Terminal launch offer: A why-note of about two lines. A model writes the sentences. Code fills every number from stored facts: the price path, volume against that coin's 20-day baseline, and the broader market move. Free includes 10 why-notes a month when the model is available. Otherwise the alert lists the facts behind the move. Trader, Pro, and Community include a note on each alert, up to a monthly fair-use count. The alert still sends with the price if the note is missing.
- Record after the alert. Nansen: Not found (Smart Alerts page). Arkham: Not found (alerts announcement). Terminal launch offer: Each alert stores the price when it fired, then 1 hour, 4 hours, 24 hours, and 7 days later. Until a later price is in, that slot says "not in yet." Free keeps receipts for 7 days. Trader and Pro keep them for 1 year. The receipt is a price record, not a rating. The rule page counts its fires. Coming: the median price change after 24 hours on the rule.
- Noise controls. Nansen: Not part of this check. Arkham: Not part of this check. Terminal launch offer: A daily message limit, default 8, and you can set 1 to 30. A cooldown, default 1 hour on price, percent, and volume rules, and 4 hours on unusual move. Quiet hours, off by default. A morning brief at 8:00 AM. Snooze and Mute on each alert. Before you save, a chart of the last 30 days marks each time the rule would have fired.
- API and machine access. Nansen: REST, MCP, and x402 at $0.01 or $0.05 a call (x402 page). Arkham: REST with alert routes. x402 since August 5, 2026, at $0.20 to $100 a call (x402 API description). The MCP guide did not open. Terminal launch offer: Coming: the API, MCP, and x402 access. They are not open to the public yet.
Where Nansen and Arkham go further
Nansen and Arkham are on-chain tools. Their alerts start from the blockchain, not from a price.
- Wallet labels. Nansen alerts on flows from wallets it labels. Arkham alerts on transfers to or from named entities. Terminal does not label wallets.
- Entity and address tracking. Arkham sets an alert on an entity or an address, by USD value or token value. Terminal does not track wallets or addresses.
- On-chain transfers and contract calls. Nansen alerts on token transfers and contract calls. Terminal has no transfer or contract alert.
- Hyperliquid positions. Nansen alerts on them. Terminal does not.
- Slack. Nansen lists Slack as a destination. Terminal does not offer Slack.
- Machine access today. Both charge for API calls through x402, and Nansen lists MCP. Terminal's API, MCP, and x402 access are Coming.
Where the Terminal launch offer is different
Terminal is a market alert with a note and a receipt. It is not an on-chain research tool.
- You set the alert on the market: a price level, a percent move, a volume spike, or an unusual move for that coin. The builder shows the percent that counts as unusual today.
- The why-note uses numbers the product stored. It describes the move. It does not tell you what to do with the coin. A why-note on the alert was not found on the Nansen or Arkham pages opened.
- Every alert grows a receipt: the price 1 hour, 4 hours, 24 hours, and 7 days later. A record of what the price did after an alert was not found on the Nansen or Arkham pages opened.
- Before you save, the last 30 days mark each time the rule would have fired.
- Quiet hours, a daily limit, a cooldown, and a morning brief are account settings.
- Free is $0 for 3 alerts, with no card. Trader is $15 a month. Paid plans are not open yet.
Checks run about every 5 minutes on Free, about every minute on Trader, and about every 15 seconds on Pro. That is the aim for each check. A message can still arrive later than that.

Unverified
- Nansen's delivery list (Telegram, Slack, Discord, and webhook). The check recorded it in the same row as the Smart Alerts page and did not name a separate page for it.
- The page that gives the 200 or 750 credit cost of Nansen's AI agent. The check recorded it next to the credits page.
- Arkham's email and Telegram delivery. Only a search summary of the alerts guide was read. The guide itself did not open.
- An Arkham consumer price. It was not found. The $900 figure is for API plans and comes from a third-party listing, not from Arkham.
- Arkham's MCP. The guide returned an error, so this page does not describe it.
- Noise controls, such as quiet hours, cooldowns, or a daily cap, in Nansen or Arkham alerts. The check did not cover them.
- Any later price after a Nansen or Arkham alert, and any note on why a price moved. Neither was found on the pages opened. A screen behind a sign-in could still show one.
