Tutorial: Parallel Finance (lending and borrowing)

September 6, 2022
September 6, 2022

Parallel Finance is a decentralised money market protocol that allows users to stake, swap, lend, borrow and take part in Crowdloans within the Polkadot ecosystem.

Similar to how DOT is the native token of Polkadot, PARA is Parallel’s native token.

For a more detailed overview of the protocol and its token, check out our pro report here.

This tutorial will go through how to lend and borrow on Parallel. Check out our previous tutorial for a guide on how to swap, provide liquidity and stake on the platform.



Getting set up 

Head to https://parallel.fi and click ‘enter app.’

The first thing you’ll need to do is connect a wallet. Polkadot.js and Parallel’s native wallet are the two wallets currently supported by the protocol, but support for other wallets is coming soon.

Click here for a quick guide on how to set up a Polakdot.js wallet and here for more on how to set up and use Parallel Wallet.

Once you have connected a wallet, you should be able to see your wallet’s balance on Parallel and the relay chain (i.e. Polkadot Mainnet). Note that if  you are using a Polkadot.js wallet, there will be an option to transfer assets from the Polkadot chain to the Parallel chain.

Towards the top of the ‘overview page,’ you’ll see that you have the option to choose between ‘Polkadot’ and Kusama. Kusama is a blockchain very similar to Polkadot. It acts as a kind of a test-net that allows developers and projects to test apps, parachains and blockchains before they deploy on Polkadot. If you click on the Kusama tab, you’ll actually be directed to Heiko Finance, Parallel’s sister protocol that operates on Kusama. For this tutorial, we’re going to focus solely on Parallel.



First, head to the ‘lend’ section of the Money Market page.

Here your wallet’s balance, as well as the ‘supply APY’ for each token will be listed. The supply APY rate is a combination of the lending APY (i.e. interest you earn for lending to the Money Market, which is paid in the same asset being lent) and the farming APY (i.e. the amount of PARA tokens you’ll earn).

Once you click on the token you want to supply, the following pop-up should appear. You can click on ‘asset analytics’ at the top of this screen to view more details about the asset on Parallel.

Next, enter the amount you want to lend. At the moment, Parallel Finance has no minimum or maximum deposit limits for lending. The ‘borrow limit’ represents the maximum amount you can borrow by using your lent assets as collateral.

Once you click ‘lend,’ you’ll be prompted to confirm the transaction in your wallet.

After this, you should now see a ‘my lend positions’ section on the Money Market page.

Your position will shortly begin to accrue interest. You can click the switch button next to your lend position to use it as collateral for borrowing, which is covered in the following section.

Note: not all assets can be used as collateral. Click here for more info.

To withdraw, click on your position followed by the withdraw tab in the following pop-up. Next, simply enter the amount you want to withdraw and confirm the transaction in your wallet.



Once you have provided collateral (as shown above), you will be able to borrow on Parallel. Currently, the only assets available to borrow are DOT and sDOT.

You’ll see DOT has a diamond icon beside it, which signifies that it is a ‘liquidation free loan.’ Basically this means that because of a relatively fixed exchange rate between DOT and certain tokens that can be used as collateral (marked by a diamond icon), DOT loans can be issued with virtually no risk of your position being liquidated. More info on this here.

Same as with lending, when you click on the asset you want to borrow, a pop-up screen will appear, and you can click on ‘asset analytics’ at the top of this screen to view more details.

Next, enter the amount you want to borrow.

The ‘limit’/borrow limit’ figures represent the maximum amount of the asset you can borrow (this value is dependent on the available liquidity and your collateral amount).

The Health factor represents the price ratio between your collateralized and borrowed asset and is therefore an indicator of the safety of your loan. If this value reaches 1, your loan will automatically be liquidated to repay your debt, and any leftover collateral will be returned to you. It’s your responsibility to ensure that the health factor remains above 1. Make sure you are comfortable with this ratio and never invest more than you are willing to lose.

The borrow APY rate represents the interest you can expect to pay for your loan.

For liquidation free loans, you’ll also have a ‘liquidation free limit’, which is the maximum amount that you can borrow without any risk of being liquidated. 

Once you click ‘borrow,’ you’ll be prompted to sign the transaction in your wallet. You should now be able to see a ‘my borrow positions’ section on the Money Market page.

Note that the interest on your loan that accrues over time will have a negative effect on the health factor, but repaying some of your loan is a way of increasing it. To do this, click on your position followed by the repay tab in the following pop-up. Next, enter the amount you want to repay and confirm the transaction in your wallet.
