Money Protocol

Before you borrow a dollar against your Bitcoin, spend five minutes doing the math a bank would do for you. Here's the exact exercise — with the numbers worked out. A bank underwrites a loan conservatively so that a bad year doesn't sink you. When you borrow against your own Bitcoin on a self-custodial protocol, that conservatism becomes your job — and the good news is it's a five-minute exercise you do once, up front. This is that exercise, worked all the way through. The setup On Money Protocol, you deposit RBTC (Bitcoin on the Rootstock network) into a vault — a smart-contract position only you control — and mint BPD , a dollar-pegged stablecoin, against it at 0% interest . No monthly payment, no credit check, one flat borrowing fee. The number that governs your safety is the collateral ratio : the dollar value of your RBTC divided by the BPD you owe. The liquidation floor is 110% — drop below it and the vault is closed to clear the debt. Stress-testing is simply...

"Just sell some" is the reflex answer when a Bitcoin holder needs cash. Here's the side-by-side that shows why, for a long-term holder, borrowing often wins on the math — and when selling is still the right move. You need $40,000. You hold Bitcoin you bought years ago, well below today's price. The obvious move is to sell a slice. The less obvious move is to borrow against it. People argue about this in the abstract; let's do it with numbers instead. We'll use one running example: $40,000 needed, Bitcoin with a low cost basis, a holder who still believes in the asset. Option 1: Sell the Bitcoin Selling looks clean — click, done, dollars in hand. But two costs hide inside it. The tax cost. If those coins carry a large unrealized gain, selling realizes it. Depending on your bracket and jurisdiction, you might owe meaningful capital gains tax on the sale. To net $40,000 after tax, you may have to sell $48,000–$52,000 of Bitcoin. The tax isn't a footnot...

You want to renovate — a kitchen, an addition, a new roof with solar — and the bill lands somewhere around $60,000. You also own Bitcoin you'd rather not sell. The default move is a home-equity line of credit. But if you hold a meaningful Bitcoin position, there's a second way to fund the same project without a bank or a sale. Here's the honest comparison. The two tools, side by side Home-equity line of credit (HELOC) Secured by your house. Underwritten over weeks, with a credit pull and paperwork. Appears on your credit report and affects your utilization. Charges a variable interest rate — in 2026, not cheap — that accrues monthly. Backed by stable collateral, so the bank lends comfortably against it. Bitcoin-backed vault loan Secured by your Bitcoin. Mints in minutes, no credit pull, no paperwork. Doesn't touch your credit report. Charges 0% ongoing interest — one flat borrowing fee up front, nothing accruing. Backed by volatile collateral, so you...

A short due-diligence checklist drawn from the 2022 CeFi collapses — and how a self-custodial vault answers each one differently. The centralized lenders that froze customer withdrawals in 2022 didn't announce their fragility in advance. But in hindsight, the warning signs were all answerable with a handful of blunt questions — questions the marketing was carefully designed not to invite. Here are five worth asking before you trust any platform with your Bitcoin, and how a self-custodial protocol answers each. 1. Can you lend my specific coins to someone else? This is the one that decides most of the others. Custodial lenders pool deposits and redeploy them — to trading desks, hedge funds, other lenders — because that redeployment is how they fund the yield they pay you. Your coins become collateral in a chain of borrowers you never see. With a self-custodial protocol, the answer is no. Your Bitcoin sits in a vault — an isolated smart-contract position only you control. It is...
