Borrowing against
lets you spend dollars without selling the
. On Aave you supply
as collateral, borrow
against it, and pay interest on the loan until you repay it. Your
stays yours the whole time, and keeps earning a little supply interest while it backs the loan.

How Borrowing on Aave Works

Aave on Base holds
as
, the ERC-20 form of ETH, so the first step is wrapping it. Once supplied, two numbers decide how much you can borrow and when you get liquidated:
  • Max LTV, 81 percent for WETH on Base. You can borrow up to 81 percent of your collateral's value.
  • Liquidation threshold, 84 percent. If your debt grows past 84 percent of your collateral's value, anyone can repay part of your loan and take some of your
    at a discount.
Aave sums this up as a health factor. Above 1 you are safe; at 1 or below you can be liquidated. The interest rate on the loan is variable and moves with how much of the
pool is borrowed.

Borrowing By Hand

  1. Open Aave's app, connect your wallet and switch to the Base market.
  2. Supply
    . The app wraps it to
    for you and turns it on as collateral.
  3. Find
    under Assets to borrow and choose Borrow.
  4. Enter an amount and check the health factor the app shows before you confirm.
  5. Confirm in your wallet. The
    arrives in the same wallet.

Borrow With Plug

Use in App
  1. Wraps 0.1
    into
    .
  2. Supplies the 0.1
    to the Aave Base market as collateral.
  3. Borrows 50
    against it, sent to your wallet.
All three happen in one run, so there is never a moment where your
is wrapped but not yet collateral. Change 0.1 and 50 to the amounts you want. If you already have
supplied on Aave, delete the first two steps and keep only the borrow.

What It Costs

We simulated the plug on Base in November 2026 with
at about $1,925.
  • Interest.
    borrowed on Aave's Base market cost 6.50 percent a year, variable. On 50
    that is about $3.25 over a year. Supplied
    earned 1.37 percent at the same time, which offsets a little of it.
  • Gas. The run used about 960,000 gas, about a cent at Base's gas prices.
  • Liquidation risk. After the run the position held $192.51 of collateral against $49.99 of debt, a health factor of 3.23. It would only reach liquidation if
    fell to about $595. Borrow more against the same collateral and that price rises with it.
Aave charges no fee to borrow beyond the interest.
