Understanding Nolus Earn

Nolus Earn lets you deposit idle assets in the protocol and collect interest paid by borrowers who open leverage positions. This article explains where that yield comes from and how it behaves over time.

Nolus Earn has one pool per protocol. The pools currently open:

cbBTC on Solana, SOL on Solana, USDC on Solana and wETH on Solana

Each pool funds the leverage positions that borrow that asset, and the USDC pool on Solana also funds Buy Now Pay Later purchases, so the interest you earn comes directly from borrower payments in the same pool.

Earn also carries NLS staking, a second source of yield on the same page. NLS leads the assets table in a row of its own, above the pools, and what it pays is the Nolus chain's staking rate rather than a pool rate. You stake and unstake through the same Deposit and Withdraw dialog the pools use, by picking NLS in the asset list. The page has no separate rewards figure and no Claim button: an unstake pays out the pending rewards of the stake it takes from, and when there are any, the Withdraw dialog with NLS picked adds a preview line reading You also receive followed by the amount in rewards. Because both sit on Earn, the page's Your Deposits figure counts your staked NLS alongside your pool deposits. Yield Earned does not: it stays a pool figure.

Nolus works on a cash basis, which means you are credited as borrowers actually pay, not on projected or accrued amounts. The yield you see is real yield backed by payments that have been made.

Collections run automatically at set intervals, so a borrower who pays late does not interrupt the flow of returns to the pool.

Rates are not fixed. They depend on how much of a pool is actually borrowed, so they move with demand and differ from pool to pool. The app shows the current figure next to each pool, and that is the number to trust. Current rates:

To protect those rates, Nolus can limit new deposits into a pool when its utilization falls below the threshold set for that pool. Capping inflows in a quiet period keeps the yield meaningful for the lenders already in the pool instead of diluting it across idle capital. Each pool has its own threshold, so one can be capped while another stays open. When a pool is capped, the Deposit dialog greys it out for a connected wallet with the line New deposits are suspended until borrowing demand picks up, and new deposits are refused until there is room again. Current status:

Interest you earn stays in the pool and starts earning alongside the amount you originally deposited. Returns compound rather than paying out at a flat rate, so a balance left in place grows faster the longer it sits. That makes Earn most rewarding for lenders with a long horizon.

Staking rewards work the other way: they build up beside your stake instead of compounding into it, and staking actions such as an unstake pay them out to your Nolus account.
