# Borrow

For borrowers: A quick way to get started

### Lock Collateral

Deposit blue-chip assets like ETH, WBTC, or other approved collateral. This locks your assets as security for the loan.

Example: Lock 1 ETH at $2,000 as collateral

* Collateral value: 1 ETH × 2,000 = $2,000
* Available to borrow at 75% LTV: 1,500 USDC

### Select Maturity

Choose a Credit Book that matches your timeline. Each Credit Book represents a specific maturity with its own rate ladder.

An example of available Credit Books could look like this (ETH borrowed against USDC):

| Maturity | Rate Range  | Available  |
| -------- | ----------- | ---------- |
| 30D      | 3.0% - 5.0% | $500,000   |
| 60D      | 3.5% - 5.5% | $300,000   |
| 90D      | 4.0% - 6.0% | $1,000,000 |
| 180D     | 5.0% - 7.0% | $200,000   |

### Receive Funds

Get instant liquidity at a rate locked for the duration of the loan. The CCV routes liquidity to your chosen Credit Book immediately.

Action: Borrow 1,000 USDC for 90D at 4.0% APY

Cost calculation:

* Interest: $1,000 × 4.0% × (90/360) = $10
* Total due at maturity: $1,010

### Maintain Health

Monitor your position to stay above the LTV threshold. If your collateral value drops, you must add more collateral or repay part of your debt to avoid [liquidation.](/spine-finance/core-concepts/liquidation.md)
