Our Vision

Dealing with money in TradFi is too much work for too little reward. It's not your imagination; the system monetizes adding friction in moving our own money.

Juniper replaces your entire financial stack with an automated smart wallet and connected services. We build tools that let you automate your financial life, always 100% in your custody and control, faster, cheaper, and better than TradFi ever could.

TradFi's take rates are our opportunity, together.

Do I need to trust Juniper with my crypto?

No, your assets remain in a wallet that only you control.
Juniper runs entirely on-chain in full transparency.

How much can I spend?

Juniper allows you to spend up to 70-80% of the value of your crypto.

For example, if you stake 10 ETH, you can get up to 7 ETH's worth of spending money. Note that the closer you get to the maximum usage, the more likely it is that a fluctuation in the price of your deposited assets could cause your collateral to be sold.

See "What happens if the value of my asset declines?" for more details.

Why are Juniper rates so low?

Juniper's rates are low because your crypto secures the money you spend.

For ETH-like assets (ETH, wstETH, rETH), the Juniper wallet uses the yield generated by staking ETH to offset the cost of spending USDC.

If you deposit WBTC, OP, AAVE, etc. or other non-yield bearing tokens, you can't offset the rate with staking yield, but you can still use these assets to increase your spending power.

What risks are associated with using Juniper?

As a DeFI smart wallet on an Ethereum L2, using Juniper carries some risks common to all crypto products, and others unique to Juniper itself. Please see this helpdesk article for a deeper walkthrough of the risks associated with using Juniper.

Do I need to have a credit score to get credit with Juniper?

No, all you need is ETH, WBTC, OP, LINK, or AAVE.

Reach out to us at if you have other cryptocurrency or digital assets that you'd like to use.

Can I use Juniper for my business?

Absolutely, it's your money!

For non-crypto, regular US bank cards (coming soon), you will need to personally verify your identity in order to receive money.

I’m not a US Citizen. Can I use Juniper?

Yes, Juniper works for everyone in the world, except in the countries listed below under "Is there anywhere I can't use Juniper".

How often do I need to make payments?

Make payments on your own schedule.

Instead of setting fixed payment dates, Juniper focuses on maintaining a balance between your spending and the value of your staked assets. See "How much can I spend" for more details.

Are there tax implications when using Juniper?

Unlike selling crypto to fund your debit card, a Juniper wallet spends stablecoins that are worth $1 when converted to fiat — which isn't a taxable event.

If you repay using USDC or fiat, that's not taxable.
If you repay using crypto, it's sold for USDC, and that is considered taxable.

Consult your tax advisor for further guidance.

What happens if the value of my asset declines?

A simple way to consider the ratio between spending and assets is that if you spend 20% of the value of your assets, you can withstand an 80% decline in the value of your assets before you should repay or add additional collateral.

Juniper will stop refilling your card if and when your money spent approaches 70% of the value of your crypto. This is to avoid having your crypto sold to cover the money you've already received.

Should the value of your assets decline further, your collateral will be sold, and your money spent will reset to zero until you deposit more assets.

Can I withdraw my assets?

Yes, your assets are in a self custodial wallet for which you have the keys - not us.

You'll need to repay any money you've spent before you can withdraw the crypto that secures it.

Is there anywhere I can't use Juniper?

Juniper does not provide service to Cuba, Syria, Iran, North Korea, Russia, Crimea, and certain disputed territories within Ukraine. Consult your exchange debit card provider for further restrictions and details.

Is Juniper a bank?

Juniper is neither a bank nor a financial institution.

Juniper is a self custodial wallet on Ethereum. Tungsten Financial, Inc. is a software company that develops a self-custodial smart wallet, using which a user can perform actions using their wallet on the blockchain on their own behalf.

Juniper does not provide credit to consumers.
