Multi-collateral lending on Canton Network

Borrow against your crypto,
without selling it.
Repay when you’re ready.

Use ETH, USDC, or CC as collateral. Borrow another asset against it, spend it, and pay it back whenever you want. Your assets stay locked, not sold, so you keep the upside.

What you get

Three ways Grape works for you.

Lock your crypto, borrow against it, repay when you're ready. No selling, no losing your upside, no waiting on bank hours.

01 / Borrow

Cash from your crypto.

Lock ETH, USDC, or CC. Borrow another asset against it, spend it, repay later. Three asset choices, three borrowing limits.

ETH50% LTV
USDC85% LTV
CC30% LTV
02 / Keep

Keep your crypto. Keep the upside.

Your collateral isn't sold, it's locked. If your crypto goes up while you're borrowing, the upside is still yours when you repay.

How it works

From sign-in to borrowed funds in four steps.

No usernames or passwords. Your wallet is your identity: sign once and you're in.

STEP 01

Sign in with your wallet.

Tap once to sign in with your Ethereum wallet. No password, no email.

STEP 02

Deposit collateral.

Pick from ETH (50%), USDC (85%), or CC (30%). Each asset has its own loan-to-value ratio.

STEP 03

Borrow against it.

Capacity, projected debt, and health factor update as you type, before you commit.

Public roadmap

An honest list of what's done, and what isn't.

If you're a developer reading this, you should be able to tell from this section alone whether we're a serious team. We think that's worth more than a sales pitch.
