Crypto margin-funding automation

Lend your idle dollars and USDT to leveraged traders. Collect the interest.

We are not an exchange, and we never touch your money. We do one narrow thing: decide how much to offer, at what rate, and for how long on the Bitfinex funding book — then watch it.

You are not investing. You are on call.

A dark room, a bright screen, in and out all night. What it costs you is sleep and attention; what it returns rarely matches.

There is a yield that does not need you watching

Some traders want a bigger position than their balance allows — $10,000 in hand, $30,000 on the screen. The other $20,000 has to be borrowed, and the lender can be you.

You do not carry their trading risk. The exchange requires them to over-collateralise and liquidates them before they can eat into your money — what they lose is their own collateral, not your principal.

Every account, on one phone

Connect all your exchange accounts and read them on one page. You only pay for the ones the bot actually lends on — and the rest keep reminding you they are not earning yet.

Numbers, measured over the same market

Same period, same capital — with "do nothing at all" included as a strategy.

Market clearing rates sat between 6.25% and 11.07% for most of the last 360 days.

Measured in a market whose median was 5.44% — the low end of the ten-year range, not a cherry-picked year. When the market itself pays more, the gap narrows. Past results do not predict future performance.

What we cannot do

Trust comes from limits, not promises. Every line below is enforced in code.
