Notional Finance is an Ethereum-based lending and borrowing software. Notional has a few methods up its DeFi sleeve to automate permissionless fixed-term loans in addition to fixed-term rates of interest.
Notional innovation within the DeFi area comes from its monetary primitive dubbed fCash. Along with Notional’s NOTE token, the dApp minimizes debt compensation. Earlier than we dive in, let’s see why not all rates of interest are the identical.
Advantages of Drawbacks of Mounted Curiosity Charges
As their title suggests, mounted rates of interest are set by a lender and accepted by a borrower for the time period of a mortgage. For debtors, this is usually a boon if charges rise — they pocket financial savings with a decrease charge.
However this could backfire in intervals when rates of interest are excessive. If a borrower locks in a excessive charge on a mortgage or a mortgage after which benchmark charges fall, they might wind up paying way over they’d have if they might decrease the charges on their loans accordingly.
That’s why lenders additionally provide adjustable charge loans and mortgages. Agian, that is nice for debtors who lock in excessive charges after which profit as they fall. But when they do the other — take out debt at a low charge — charges might rise and make the loans costlier to service.
How Does Notional Finance Work?
Notional Finance has its personal tackle mounted charges. Like Aave, Notional Finance is your customary Ethereum-centric lending dApp. Its key differentiating characteristic is fixed-term borrowing, because of the novel implementation of fCash. Earlier than we clarify fCash, let’s first remind ourselves how DeFi lending works:
- In DeFi, there isn’t a market maker offering liquidity for the loans. As a substitute, customers themselves grow to be makers or liquidity suppliers (LPs).
- LPs deposit their crypto/stablecoin belongings into liquidity swimming pools, by connecting to the dApp with a non-custodial pockets like MetaMask or Block Pockets.
- Liquidity swimming pools are sensible contracts, serving as automated governance that determines situations beneath which debtors can drain the pool’s liquidity for a mortgage. Such situations are: collateral’s loan-to-value ratio % relying on the token kind, borrowing charge %, and mortgage maturity date.
- In DeFi, there isn’t a unsecured mortgage (with out a collateral), as a result of there isn’t a human ingredient to verify for the borrower’s creditworthiness.
- To obtain a mortgage, debtors deposit their very own funds into a wise contract as a collateral. In trade, the LPs obtain an rate of interest, making them into individualized, nameless, digital banks.
Notional Finance follows this fundamental DeFi lending/borrowing precept. The novelty comes with Notional’s twin liquidity swimming pools, holding DAI on one aspect, and fDAI on the opposite aspect, representing fCash.
As of November 2022, Notional had a complete mortgage quantity of $659M, protecting over 1,000 energetic customers. The lending platform helps 4 kinds of belongings for each lending and borrowing: USDC, WBTC, DAI, and ETH. However how does fCash match into this mannequin?
fCash permits customers to maneuver capital via time. Let’s say you wish to borrow $10,000 price of DAI from Notional. Accounting for the rate of interest, you comply with pay 10,500 DAI at a future date, usually between 3 weeks to 1 yr for stablecoins and as much as six months for ETH and WBTC.
The borrower then receives the tokenized type of that debt obligation, expressed as -10,500 fCash, accounting for that future cost and redeemable for 10,500 DAI on maturity date.
This is the reason there’s a prefix “f” earlier than Money, whereby the worth distinction between DAI and fDAI is the collected rate of interest. In different phrases, when debtors deposit their collateral, they mint fCash tokens, which lenders obtain as fCash.
In flip, these fCash tokens might be exchanged for different cryptocurrency, corresponding to ETH, WBTC, USDC, or DAI. On the finish of the road, debtors obtain the asset they need, conserving in thoughts to pay it off on maturity date.

In the event that they fail to repay the mortgage, debtors threat liquidation of their overcollateralized belongings. In fact, due to their secure nature, stablecoins have a decrease overcollateralization at 120%, whereas WBTC and ETH have an overcollateralization stage at 150%.
Exterior of repaying the mortgage, debtors can prolong the longer term maturity date, which known as rolling on their contract.
Notional’s nTokens and cTokens
An alternate approach to offer liquidity is thru nTokens. When lenders present liquidity into liquidity swimming pools, they obtain nTokens as ERC-20 belongings. They characterize tokenized maturities for the deposited cryptocurrency, redeemable for “a share of Notional’s complete liquidity in a given forex throughout all energetic maturities.”
For instance, if LP offered DAI stablecoin right into a liquidity pool, they obtain nDAI. Likewise, for nETH and nUSDC.

nTokens themselves can be utilized as a collateral for borrowing. Moreover, LPs earn passive earnings with their nTokens for merely holding them, on buying and selling charges (when folks borrow their belongings), on fCash rate of interest, and when receiving NOTE incentives.
Native to the Compound protocol, Notional built-in cTokens as interest-bearing belongings. As such, they improve returns for liquidity suppliers in an identical method as nTokens. In Notional V1, solely fCash was used as a settlement asset.
This modified in V2, whereby cToken, corresponding to cUSDC or cDAI, represents settlement upon maturity. This division enabled Notional to extend LPs returns as they deposit cTokens into liquidity swimming pools as a substitute of the underlying forex.
Likewise, cTokens allow mounted charge loans to build up variable cToken charge as quickly because it reaches maturity.
Notional NOTE Token
The lending protocol has neighborhood governance with NOTE tokens serving as proportional voting energy. As a monetizing mechanism, Notional customers can stake NOTE tokens, that are then transformed into 80/20 NOTE/ETH Balancer LP tokens.
In return, stakers obtain sNOTE tokens as rewards, redeemable for Balancer LP tokens. Though this could change with neighborhood voting, on a weekly foundation, Notional allotted 30,000 NOTE tokens to incentives sNOTE holders.
The overall NOTE provide is 100M, practically all of them in circulation. Within the case of surprising liquidations, Notional will faucet into NOTE reserves to pay again lenders.
Notional Finance Founders
Teddy Woodward and Jeff Wu conceived Notional Finance in November 2019 at a hackathon occasion in San Francisco. In January 2020, they launched the venture on Ethereum.
As of April 2021, they raised $11.3M throughout three funding rounds, largely equipped by Pantera Capital, Polychain, and Coinbase Ventures.
