Notional

Notional is a DeFi fixed-income protocol that enables users to lend and borrow crypto assets at both fixed and variable interest rates on Ethereum and Arbitrum. Built around its Prime Money Market (variable-rate lending/borrowing) and fCash-based fixed-rate liquidity pools, Notional serves retail and institutional users seeking predictable yields, over-collateralized loans, or leveraged exposure through whitelisted vault strategies. The protocol is governed by NOTE token holders who set risk parameters, fees, and incentive emission rates.

Notional generates yield through five main ways.

1. Variable-rate lending (Prime Money Market). You deposit assets like USDC, DAI, or ETH into a pool and receive Prime Cash tokens (for example, Prime USDC). Their value grows over time as borrowers pay variable interest. The interest rate follows a curve with two "kink" points — as more of the pool is borrowed out, the rate rises, with two specific thresholds and rates set by the protocol's governance, up to a maximum. Lenders earn a share of the total interest paid by borrowers, spread across all supplied funds. There are no fees to enter or exit this type of lending.

2. Fixed-rate lending (fCash). You buy fCash — think of it as a tokenized bond with a fixed return — at an interest rate set by supply and demand in Notional's fixed-rate pools. The rate is locked until a specific maturity date (quarterly or semi-annual). When you enter, you pay an upfront fee equal to 8% of the total interest you expect to earn until maturity. If you exit early, you pay another 8% fee on the remaining interest at the current market rate. If you hold until maturity, there is no exit fee. The total fee amount grows or shrinks with the time left until maturity.

3. Providing liquidity (nTokens). Liquidity providers deposit into fixed-rate pools and receive nTokens. The nTokens hold their cash in Prime Cash (earning variable interest) and take the opposite side of every fixed-rate trade — when someone borrows at a fixed rate, the nToken effectively lends at that rate, and vice versa. Returns come from three sources:

• Interest earned on Prime Cash and on the net fCash positions.
• Transaction fees from every fixed-rate lend or borrow trade (currently 8% of the pre-fee interest, split between liquidity providers and the protocol).
• NOTE governance tokens distributed to nToken holders as incentives.

4. Leveraged Vaults. Approved external strategy contracts (for example on Curve, Balancer, or Uniswap) let you borrow from Notional at fixed rates and put that borrowed capital to work in external strategies, with up to roughly 10x leverage. Your return is calculated as: ((your capital + borrowed amount) × vault return − borrowed amount × interest rate) / your capital. You pay Notional's fixed interest on the borrowed amount plus any trading costs when converting between the borrowed asset and the vault's strategy asset. The vault assets act as over-collateralization — if the position drops below a minimum collateral ratio, it can be liquidated.

5. NOTE Staking (sNOTE). NOTE holders can stake by converting NOTE into 80/20 NOTE/WETH Balancer LP tokens, receiving sNOTE in return. sNOTE earns rewards from three sources:

• Protocol revenue reinvestments (transaction fees from lending/borrowing, plus COMP incentives from Notional's Compound integration).
• Balancer pool trading fees.
• Additional NOTE incentives allocated by the community (currently 30,000 NOTE per week).

sNOTE can be redeemed after a 15-day cooldown, within a 3-day redemption window. In a collateral shortfall, NOTE holders may vote to take up to 50% of sNOTE pool assets to help recapitalize the system.

Variable-rate borrowers also pay a borrow fee — a governance-set percentage of the pre-fee borrow rate (bounded by minimum and maximum fee rates). That fee goes to the protocol reserve and partly funds sNOTE rewards.

Notional Finance has disclosed two funding rounds via official blog posts:
