The problem

Credit stopped innovating and started extracting. The card industry solved the hard part decades ago, then spent the years since perfecting the squeeze: 20 to 30% APR, minimum payments engineered so the balance never dies, penalty fees timed for the worst possible moment, and a rejection for anyone without the right paperwork.

Bitcoiners are squeezed from the other direction: asset-rich and cash-poor by choice. Selling means a taxable event and giving up the upside, so they will not sell, yet they still need dollars. The existing ways to borrow against bitcoin are custodial, opaque, gamified, or region-locked, and the household names that tried it (Celsius, BlockFi) blew up by rehypothecating customer funds. A real, urgent, recurring need with no trustworthy home.

The product

The same daily feel as the Chase or Discover card you already use, except the limit is backed by your bitcoin instead of your credit score.

1
Deposit bitcoin
Held in 2-of-3 collaborative custody. You hold a key, so we cannot move it alone.
2
Get a USDT credit line
Instant, backed by your bitcoin. Your collateral qualifies you, so no credit file is needed.
3
Spend anywhere
Tap your card anywhere Visa is accepted, or withdraw USDT to your wallet.
4
Repay or top up
Flexible, and instant over Lightning. Your bitcoin stays yours, and keeps its upside.
Always overcollateralized
40 to 50% LTV to start, up to 60% as your grade improves. Liquidation only near 85%, so a wide safety band.
Non-custodial by default
2-of-3 collaborative multisig. You hold a key, so we literally cannot misuse your coins.
Cheaper and rejection-proof
Lower APR than unsecured credit, no taxable sale, and approval never depends on a credit file (KYC and AML still apply).

How your bitcoin is secured

The honest mechanics behind the slogans. This is the part every lender before us buried, and the part that killed them.

Loan-to-value40 to 50% to startYou borrow at most half your bitcoin's value, so the price has wide room to move first.
Liquidation threshold~85%You are warned at every band long before. Only as a last resort do we sell the smallest slice to make you safe.
Price feedPublic, independent indexLiquidation runs on a disclosed third-party feed, never on our own book.
Custody2-of-3 multisig, you hold a keyRehypothecation is structurally impossible, not a promise. Native bitcoin, never wrapped.
Collateral to dollarsUSDT facility, no saleYour bitcoin secures a USDT credit facility. It is not sold or moved to fund your line.
Repay and top upInstant over LightningLow-fee Lightning settlement for repayments and top-ups. Spend settles as USDT on Visa rails.

Who it is for

Bitcoin holders who refuse to sell
You own bitcoin and will not sell it. Borrow against it at better terms than unsecured credit, keep the upside, and stay non-custodial. A product Chase structurally cannot offer.
The people the banks turned away
No credit file, the wrong country, no history. Your bitcoin is your qualification, no FICO and no passport test (KYC and AML still apply). We say yes where Chase says no.

Why it wins

Every competitor is a feature: a loan desk, a borrow button, or a cashback card. None pairs a non-custodial bitcoin credit line with a card and local-rail spend layer in the emerging markets where the need is highest. Ledn and Coinbase lend, but they do not put a spendable card in your pocket in Manila. Our edges compound: multi-issuer card redundancy, so no single BIN sponsor can brick us (the number-one card killer), and an underwriting-data flywheel that graduates trusted users toward unsecured credit.

Non-custodial collateral
Funds cannot be misused by construction, not by promise. Native bitcoin in multisig, never wrapped.
Open by default
Continuous proof of reserves and liabilities, not a quarterly snapshot.
Never rehypothecate
The exact thing that killed Celsius and BlockFi. We do not do it, and by construction we cannot.
Licensed rails from day one
A Visa principal-member issuer with multi-issuer redundancy, a licensed local rail for the Philippines (BSP and EMI), and a Singapore holdco on the MAS payments track.
Skin in the game
Built for the bitcoin community, not extracted from it.
No predatory tricks
The industry makes its money when you lose track. We make ours one way, on a rate you agreed to and can always see. Interest is the business, and we will never hide that.

Business model

A real interest-earning balance sheet, not a trading spread. Users borrow at roughly 10% (6 to 16% by grade). Our debt facility costs us less than that, and we keep the net spread on the average drawn balance, plus interchange on every dollar spent and a thin, transparent FX margin. Overcollateralized lending means charge-offs are a fraction of Chase's 5 to 6%, so we keep more of the spread and we do not blow up. The first milestone is modest: roughly 10,000 cardholders from the Network School and bitcoin-community beachhead puts the book at $100k MRR, and the same engine scales to $3M ARR and beyond.

Why us

The founder is the customer: a heavy credit user (Chase, Discover, Wise) who pays more in credit interest than any other expense and understands the borrower from the inside. Two technical operator founders who ship, with native distribution into Network School and the global bitcoin community. The two rails the product runs on both have credible, redundant integration paths we are actively pursuing: native bitcoin collateral in collaborative multisig, and a USDT credit line plus a Visa card through a licensed issuer, settled over Lightning rails of the kind IBEX provides. No counterparty is signed yet, and we will never claim one that is not.

Comps are public market caps, shown as color, not a valuation target. Bottom-up: of the roughly 500M people who hold bitcoin, even a small share borrowing a few thousand dollars at a ~10% net spread is a multi-billion-dollar revenue pool. Sources: crypto-collateralized lending trackers, 2025.

Roadmap

V1
Secured bitcoin-backed credit line plus USDT card. Non-custodial, radically transparent, Lightning for repayment and top-ups.
Data
Record how our own users borrow and repay. The proprietary underwriting moat.
Graduate
Layer crypto credit scoring and move trusted users to higher LTV, then unsecured revolving credit. The true credit-card moment.
Bank
Accounts, a savings funnel, more markets. The full bitcoin Chase.

The ask

Raise a $750k pre-seed of mission-aligned equity (target investors we are talking to: Fulgur, Curious Ventures, Network School angels). It buys roughly 15 to 18 months of runway: a team of two to three, licensing and launch in the Philippines, and the first cardholders on the book, the proof on the path to $100k MRR. Separately, arrange a USDT credit facility (debt) to fund the loan book, so we never dilute the company to fund lending. The business throws off interest income and becomes self-funding as it scales.
