Your own payments overview on Modern Treasury, built around how your money moves.

  • Payment orders, counterparties, expected payments and transactions, straight from Modern Treasury.
  • AI that matches incoming payments to what you expected, with you approving every payment order.
  • A screen for your finance team and a short email every morning.

Ask your chat

Answers straight from your Modern Treasury data, in Claude or another chat with the full Hypamoon connection.

  • Which expected payments have not arrived yet this week?
  • Which payment orders are waiting for approval?

When something happens

Modern Treasury sends a webhook to your app, and the app asks AI what happens next.

  1. When

    Modern Treasury reports a new incoming payment.

    AI decides

    AI compares the amount, the sender and the reference with open expected payments and proposes a match.

    Then

    Your finance team gets an email with the matches to confirm.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Modern Treasury data.

  • For your team

    An approval screen for your finance team with the payment orders that wait for a second pair of eyes.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    An agent prepares a payment order from an approved invoice, and it only goes out after you approve.

    AI proposes, you approve

Modern Treasury stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Modern Treasury waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • Webhook endpoints are set for the whole organization, with separate URLs for live and test traffic.
