Two things are live in preview: the deposit widget and the deposit API. Start by seeing the flow, then wire it into your app.

​
See it live

The deposit widget runs at widget.rheon.io. Open it to walk through the deposit flow end to end.

​
The deposit flow

A deposit moves through these steps:
  1. Launcher - the user opens the widget
  2. Amount - they choose how much to deposit
  3. Fund with - they pick a wallet, an exchange, or a card
  4. Connect - they connect the chosen source
  5. Review - they confirm the amount and route
  6. Routing - Rheon settles the funds cross-chain
  7. Success - the USDC lands

​
Integrate it

There are two paths, depending on how much control you want:

Deposit API

Available now. Call quote, transaction, and status to build your own UI. Non-custodial - the user’s wallet signs; funds never touch Rheon.

Embeddable widget

Coming soon. Drop the widget into your page via iframe or SDK, themed to your brand, with lifecycle events.

​
API in three calls

1

Quote

POST /deposit/quote with source, destination, and amount → a quote.
2

Build

POST /deposit/transaction with the quote → the unsigned transaction (and an approval if the token needs one).
3

Sign and track

The user’s wallet signs and submits; poll POST /deposit/status until it is done.
See the API reference for the full request and response shapes.

​
Knowing when a deposit lands

Credit the user only when a deposit reaches done. Today you learn that by polling /deposit/status; webhooks that push the update to your backend are coming soon. See Transaction statuses.
