On some routes the money has to be in place before a payout goes out, so borrowing at the last moment does not help. That USDC waits in the wallet earning nothing.
Problem
Money that has to be in position ahead of time still earns zero.
Borrowing against Bitcoin solves the routes where a payout can be funded the instant it goes out: pledge BTC,
take USDC, send the payment, repay when the customer's money arrives. It does not solve every route. Where
delivery runs through a local partner with its own capacity and cut-off times, the dollars have to be sitting
there hours or days ahead. Treasury keeps USDC waiting so those payouts can go out on time.
Delivery is not instantLocal cut-off timesToo late to borrow
This is the old bank-account problem carried into stablecoins. The money sits at 0% because its
whole job is to be spendable today. Putting it anywhere you cannot pull it back in time just trades idle cash
for a missed payment.
Solution
Lend the waiting USDC on Morpho Midnight. Earn while it sits. Pull it back when a payout needs it.
Meridian's treasury already owns Bitcoin — that backs the borrowing side. The USDC that has to
sit and wait can work on the other side: lend it on Morpho Midnight for one or three days at a
rate agreed up front. While no payout needs those dollars, they earn instead of sitting at zero. When a payment
does need the same cash, Meridian takes it back early rather than waiting for the term to end.
This is still lending backed by collateral, under an agreement. Meridian is the lender. The
borrower on the other side pledges Bitcoin, and the Midnight contract sets what is owed, by when, and what
happens if it is not repaid. Meridian is not handing idle USDC to an unknown counterparty on trust.
Today · idle USDC
Cash sized for the busiest day that route has
Sits in the wallet at 0%
Bitcoin sits unused next to it
No way to earn on it without risking the payout
Midnight · working USDC
Same cash, lent for one or three days
Backed by the borrower’s Bitcoin
Rate and end date agreed up front
Payout due → take the cash back, rest keeps earning
Same treasury, two roles. Where a payout can be funded the moment it goes out: pledge Bitcoin, borrow USDC
(brief 1).
Where the money has to be in place ahead of time: keep it, lend it, pull it back. Bitcoin is never sold to fund a payout.
How it works
→→→→
Meridian lends USDC at a known rate to a known date. The loan is written into the Morpho Midnight agreement and
backed by the borrower’s pledged Bitcoin. Meridian is not tied to one named borrower. If a payout needs the cash
before that date, Meridian ends the loan early and the dollars are back in the wallet.
Getting the cash back — two options
Earning on the money only matters if it can be pulled back when a payout is due.
Take it back early
Pass the loan to someone else at today’s rate. If rates have fallen since Meridian lent, that can pay a little extra. If rates have risen, it costs a little — the price of getting the cash back today.
Wait until the end date
If no payout needs the money, Meridian is repaid in full on the due date. Nobody else has to take the other side. This is what happens when the cash was not needed.
Taking the cash back early only works if someone is willing to take over the loan. Lend only as much as the
market can realistically absorb, and keep a small amount in the wallet for routes where a payout cannot depend
on finding a buyer.
Worked example
800k USDC waiting on a route. Quiet for two days, then a 500k payout comes due.
Old way: 800k sits in the wallet all month at 0%, while Bitcoin sits unused next to it. New way: lend the 800k
for three days at 5.2%, to a borrower who pledged Bitcoin under the Midnight agreement. On day one a 500k payout
has to go out. Meridian takes 500k back and leaves the rest lent until the end date.
USDC lent800,000 for 3 days at 5.2% APR
If held 3 days, interest≈ 342 USDC
Day-1 pull-back for the payouttake back ≈ 500,000
Remaining 300k to the end datekeeps earning 5.2%
Vs 800k idle at 0%Earns on unspent cash; payout still goes out
Numbers are illustrative. Pulling the cash back when rates have risen costs a little. That is still better than
earning nothing with no way to get the dollars back.
