The Greenwood Card.

Limits, freezes and new cards, all from the app and all settled onchain.

Dynamic limits

Limits move with the account rather than with a call centre. Raise or drop them from the app, signed with your passkey.

Instant freeze, onchain

Freeze is a toggle, not a support ticket, and it settles on Robinhood Chain in about 100 ms like everything else.

Unlimited virtual cards

One numberless piece of metal, and as many virtual cards behind it as you want, each killable on its own.

Gas abstracted

Fees are paid in USDG or in points. You never hold ETH to buy coffee, and card authorisations are sponsored outright.

Money that sits still.

Five frictions the old system still treats as normal.

  1. Idle dollars

    Cash sits still while everything else compounds.

  2. Selling winners

    Dinner should not cost you the position.

  3. Custody risk

    A balance you do not control is a promise.

  4. Gas for coffee

    Holding ETH to buy a flat white is not payment.

  5. Closed markets

    Your money keeps hours. Your life does not.

Held. Grown. Spent.

Every action prints its settlement. On ~100 ms rails, proof is faster than a spinner.

Held. Your keys never left.

Your balance lives in USDG, the Paxos-issued Global Dollar, inside an ERC-4337 smart account only you control. Greenwood cannot move, freeze or lend it without your signature.

Grown. Yield kept running.

Idle dollars auto-route into Morpho-powered onchain vaults at an estimated 7.5%* APY as of 8 August 2026, compounded sweep by sweep and withdrawable at any time.

Spent. Front row, sold out.

Tap the card. Authorisation settles as a paymaster-sponsored transaction in about 100 ms, and you never hold ETH to buy coffee.

An app designed to compound.

Self-custody in your pocket. Keys on your device, yield running underneath, and the card in the same place you check the balance.

Your keys stay yours

A smart account protected by your device. Greenwood cannot move, freeze or lend your balance without your signature.

Watch it compound

Idle dollars route into Morpho-powered vaults at an estimated 7.5%* APY. Accrual stays visible in the app.

Every card, one place

Freeze the card, create a virtual one or change a limit in seconds. Authorisation settles in about 100 ms.

Know before it matters

Borrow against Stock Tokens with health-factor alerts before a position needs attention.

Every second.

Yield accrues on screen rather than arriving as a monthly line item. Idle dollars sit in Morpho-powered vaults and compound sweep by sweep.

Every signature.

Send, deposit, reveal, freeze. Each one signs with the passkey already on your device. No password, no seed phrase, no support ticket.

Every receipt.

Each action prints its own settlement: the latency it took and the block it landed in, while a spinner would still be turning.
