Send and receive money

🌐

With your identity verification (KYC) approved you can send and receive USDC and USDT in seconds, 24/7, with no banking hours.

Send money

  1. Go to Send.
  2. Enter the amount and choose the asset (USDC or USDT) and the network: Base (recommended), Ethereum, Polygon or Arbitrum.
  3. Enter the destination address (0x… format) or pick a saved contact to autofill it.
  4. Review the Confirm transfer screen: you'll see your available balance and the network fee — ~$0.00, Bridge covers gas.
  5. Confirm. The transfer usually completes in less than 2 minutes and you can track it in Activity.

After sending to a new address, the app offers to save it as a contact for next time. You'll also get an email receipt for every transfer.

Check the network before sending. Sending to a correct address on the wrong network can mean losing the funds. When in doubt, use Base.

From the mobile app you can also send to another D-ONE CASH user's email address (P2P), no addresses involved.

Receive crypto

  1. Go to Receive → Crypto.
  2. Choose the network (Base, Ethereum, Polygon or Arbitrum).
  3. Share your address or the QR code with whoever is paying you (Copy address button).
āš ļø

Only send USDC or USDT to this address on the selected network. Wrong network = lost funds.

Request a payment from a contact

If the contact has an email saved, you can ask for money without sharing addresses:

  1. In Receive → Crypto, use Request payment from a contact.
  2. Pick the contact, enter the USDC amount (optional) and a note (optional).
  3. The contact receives the request by email with your payment details.

Contacts

In Contacts you save frequent recipients with a name, email (optional) and EVM address. Contacts show up as shortcuts when sending and when requesting payments.
