Flexline: put your crypto to work without selling it

You shouldn’t have to sell your crypto to access capital. That’s the problem Flexline was built to solve.

This is the first in a three-part series. Each post goes deeper into the mechanics, the trade-offs, and the decisions worth thinking through depending on your situation.

TL;DR

• Flexline is a fixed-rate, crypto loan – not margin trading, not DeFi
• Three distinct profiles benefit most: long-term holders who need liquidity, traders who need liquidity without closing their positions, and builders or businesses with crypto on their balance sheet
• In every case, the logic is the same: keep your position intact, access the capital you need, know your costs up front
• Rates: 7–25% APR (fixed). Terms: two days to two years. Off-platform withdrawals supported.

1. The long-term holder who needs liquidity

Meet Marcus. He’s been holding BTC and ETH since 2019. He’s not a day trader. He checks the charts, knows his cost basis, and has strong conviction about where things are going over the next few years. By any measure, he’s built something real.

Then a property deal appears. Significant deposit required. Two-week window.

The instinct is to sell. But selling means triggering a taxable event, crystallising gains he’d rather let run, and permanently exiting positions he still believes in. He’s looked at DeFi lending too. He found it technically complicated and, after the events of the last few years, not somewhere he wants to put serious collateral.

What Marcus needs is a loan against what he already holds, from a platform he already trusts, at a rate he can plan around. Not a complicated structure. Not a long process. Just capital on a defined timeline, with costs he can see from the start.

“I didn’t spend five years building this position
to sell it at the first moment I needed cash.”

With Flexline, Marcus’s BTC and ETH on Kraken are automatically considered valid collateral. He takes out a loan and withdraws the funds off-platform. His position stays open. His capital is available.The rate is fixed for the full term. The timeline is his to choose, from two days to two years.

He’s not giving up what he built. He’s making it work.

This is a common profile among Flexline users: significant long-term holdings, a real-world capital need, and a strong preference not to sell. In the first week of Flexline’s launch, users were selecting loan terms of up to 672 days. That’s not a bridge. That’s a long-term liquidity strategy.

Why Flexline fits:

• Off-platform withdrawals – funds can go wherever they’re needed
• Terms up to two years – built for long-term planning, not just short-term gaps
• Fixed rate – the cost is known from day one, not subject to market movements
• Multi-asset collateral – BTC, ETH, and more across 48 supported assets

2. The rate-sensitive trader

Priya has been trading crypto with leverage for three years. She understands margin mechanics, she tracks her liquidation price, and she’s built a risk management process that most retail traders don’t bother with. She’s careful. She’s also been getting frustrated.

Spot margin rates are fixed once a position is open, but the rate that applies is whatever is prevailing at the moment you enter. During periods of high demand, that rate can spike significantly. For a trader building a thesis around a multi-week position, opening into an elevated rate environment can make the numbers not work before the market has even moved.

She wants to know her borrowing cost before she commits, not discover it at the moment of execution.

“The market doesn’t wait for rates to calm down.
Flexline means I don’t have to either.”

Flexline gives Priya a rate agreed upfront, for the full term, regardless of what margin demand looks like when she’s ready to trade. She can build her cost of borrowing into the thesis before she enters, keep her core long-term holdings intact as collateral, and deploy capital without the risk of opening into a rate spike she didn’t see coming.

For positions where timing and cost certainty matter, Flexline changes the math.

Here’s what that rate range means in practice: at 7–25% APR fixed, shorter terms come with lower rates. A two-day loan looks very different to a two-year loan. The structure rewards traders who can be specific about their timeline, and Priya is exactly that kind of trader.

Why Flexline fits:

• Positions stay open – borrow against your holdings without closing what’s already working
• Customizable LTV – leverage is a choice, not a default
• Core holdings preserved as collateral – long-term positions stay intact
• Capital stays deployed – access liquidity without unwinding a position mid-thesis

3. The builder with crypto on the balance sheet

David co-founded a crypto-native project in 2021. The team has grown. The product is live. The treasury is predominantly crypto. That’s how the business was built, and it’s where the value sits. Right now, the business needs working capital. Not speculatively. Just operationally: payroll, infrastructure, a short-term funding gap ahead of the next raise closing.

Traditional lenders don’t recognise crypto assets as collateral in any practical way. The ones that do come with long processes, high minimums, or both. Selling from the treasury is a last resort. It disrupts the cap table, signals the wrong things, and liquidates assets the team would rather hold through the next cycle.

David needs capital that treats the balance sheet as it actually exists.

“We built this business in crypto. It shouldn’t take three months and a law firm to borrow against it.”

Flexline offers secured borrowing capacity against multi-asset collateral, with off-platform withdrawals and terms long enough to function as genuine working capital rather than a bridge. Two-year terms mean it can sit on the business’s financial plan like a facility, not a fire drill. Fixed rates mean the cost of capital is predictable, which matters for anything going into a financial model or board presentation.

For businesses and builders operating in crypto, the credibility of the lender matters too. Kraken’s Proof of Reserves, regulatory standing, and custody infrastructure aren’t just marketing. They’re operational requirements for any serious commercial relationship. When you’re borrowing against a business treasury, you need to know who holds your collateral and that they’ll still be there when the term ends.

Flexline is designed to answer both questions before you need to ask them.

Why Flexline fits:

• Large borrowing capacity – multi-asset collateral accepted across 48 supported crypto assets
• Off-platform withdrawals – funds can go to bank accounts, investment vehicles, or wherever the business needs them
• Fixed rates – predictable cost of capital for financial planning and modelling
• Terms up to two years – genuine working capital, not a short-term patch

Three profiles. One underlying idea.

The situations are different. The underlying logic isn’t: you’ve built something, and you shouldn’t have to give it up to access what you need.

Flexline is already live. Deep-dive blogs on the long-term holder, the rate-sensitive trader, and the builder are coming.

Using Kraken Flexline involves risk, may have tax implications, and may result in the loss of capital. Borrowed assets subject to withdrawal limits. Availability of Kraken Flexline is subject to certain limitations and eligibility criteria.
