A margin desk on Robinhood Chain

Every market. Every hour.
One account of buying power.

The desk never closes. Deposit stock tokens, ETF tokens or crypto as collateral, draw USDG buying power against the whole basket, and carry a single maintenance requirement that is the same at 3am on a Sunday as it is at noon on a Tuesday.

How it works

A margin desk, not a money market.

No pools per asset, no per-position limits. The desk looks at your whole basket the way a prime desk would: one collateral value, one debit, one requirement.

01

Deposit collateral

Stock tokens, ETF tokens or crypto join your account and open buying power immediately. Cash USDG counts too.

02

Trade with USDG buying power

Buys draw cash from the public vault and the purchase settles straight back into your collateral. Sells pay the debit down first.

03

Carry one requirement

Interest accrues on the debit every second and is charged once a day, every day. Stay above maintenance and the whole basket works as one.

Cross-margin by design

Requirements are set per asset class and summed across the basket, so diversifying collateral is rewarded instead of siloed.

Open every hour of every day

No sessions, no holidays, no different requirement after hours. The debit ticks against a per-second index and settles in cash at 00:00 UTC every day: USDG first, then crypto, then stock and ETF tokens.

Routed through Uniswap

Orders fill against Uniswap pools on Robinhood Chain in one transaction, with every fill bounded against the oracle mark.

Rules, not surprises

Calls are raised at any hour with a grace window sized only to the shortfall, penalties are fixed per asset class, and forced sales stop at initial margin, never further.

Assets stay put

Purchases settle into your Callside account as collateral. Buying power and assets never leave the desk mid-trade.

Revenue you can verify

The protocol keeps 20% of gross interest, which funds the vault's insurance line before it reaches the foundation treasury. Every settlement is a chain event you can check.

Markets

Tokenized stocks, ETFs and crypto, side by side.

Every asset carries one initial and one maintenance rate, and they hold at every hour of every day. Marks come from this test deployment's own oracle feeds; stock and ETF tokens are issued by Robinhood Assets (Jersey).

One table, one set of rates: what a stock token carries at 2pm on a Wednesday is what it carries at midnight on a Saturday.

Cash vault

The other side of the desk.

Every dollar of buying power is funded by one public USDG vault. Depositors earn the interest margin users pay, less a 20% protocol share, and yield shows up in the share value every second. An insurance line inside the vault absorbs losses before depositors do.

FAQ

The fine print, in plain words.

What is the debit balance?+−
The cash the desk has drawn from the vault on your behalf, plus interest accrued since the last daily charge. It ticks every second and it is the number a sale pays down first.
When is interest charged?+−
Once a day at 00:00 UTC, in a fixed order: your USDG cash first, then crypto, then stock and ETF tokens. The charge runs every day, weekends and holidays included, because the desk never closes.
What happens below maintenance?+−
The account enters a maintenance call with a grace window sized to the shortfall, at whatever hour equity crosses the line. Cure it by depositing collateral or selling to cover. If the window lapses, or equity falls below 75% of maintenance, the desk runs a forced sale back to initial margin with a stated penalty per asset class.
Where does protocol revenue go?+−
The protocol keeps 20% of gross interest and vault depositors keep the rest. That share builds the vault's insurance line to its 4.0% target first; once the line is funded, revenue accrues in the vault and sweeps whole to the foundation treasury. Every settlement is an on-chain event, listed unedited on the protocol page.
Where do my assets live?+−
In the Callside margin account contracts on Robinhood Chain. Trades settle atomically inside the account through Uniswap pools, and withdrawals are allowed whenever equity stays at or above initial margin.
What are stock tokens?+−
Tokenized debt securities issued by Robinhood Assets (Jersey) Limited that track the underlying share price. They confer no shareholder rights, and holders carry the issuer's credit risk.
Who can use Callside?+−
Callside is not available to persons in the United States, Canada, the United Kingdom, Switzerland, the United Arab Emirates or any sanctioned jurisdiction. Using the desk is an attestation that you are eligible.
