ActiveNapier Review 2026: Fixed Yield on 13 Chains, Small TVL
Napier is a modular yield tokenization protocol that lets users fix or trade yield on interest-bearing assets across many chains. Its listed TVL is very small, so treat it as a niche, early-stage product.

Our verdict on Napier
5.8/10Napier suits experienced DeFi users who already understand yield tokenization and want fixed or tradable yield across several chains. Its main strength is the permissionless, modular approach, with markets showing clear Fixed APY and Pool APY figures. The main caveat is scale: about $108K in TVL, unpublished fees and only two audits of unspecified scope. Beginners and anyone needing deep liquidity should start small, read the audits and the market terms first.

What is Napier?
Napier is a modular yield tokenization protocol that has been listed on DefiLlama since July 2024. It says it lets users own, manage and create yield products without permissions.
The app's market page shows Pool APY and Fixed APY figures, with Portfolio and Investment sections plus a curator mode. DefiLlama lists deployments on 13 networks, including Ethereum, Base, Arbitrum, Sonic, Hyperliquid and Plume.
Total value locked is about $108,000, up 1.8% over seven days. That is small for a protocol spread across so many chains, so liquidity per market is likely limited. DefiLlama shows no native token and lists two audits.
How Napier works
Yield tokenization splits an interest-bearing asset into parts, typically a principal part and a yield part. The principal part can be held for a fixed return, while the yield part lets traders speculate on future variable yield. Napier describes its protocol as modular and permissionless, which means anyone can set up yield products.
The app lists markets with a Pool APY and a Fixed APY. Liquidity providers supply capital to pools and earn from them, while fixed-rate users aim to lock in a return until maturity. The exact mechanics, such as the AMM design and the supported assets, are not described publicly, so check the documentation.
Napier also has a curator mode, which suggests that some users can configure or manage markets. How curators are chosen or rewarded is not stated publicly.
6 features
Key features
01
Yield tokenization
Napier describes itself as a modular protocol for tokenizing yield, so interest-bearing assets can be split into separate yield components.
02
Fixed APY markets
The app shows a Fixed APY figure for markets, which suggests users can lock in a set return on supported assets.
03
Pool APY
Markets also display a Pool APY, indicating liquidity pools that users can provide capital to.
04
Permissionless market creation
DefiLlama says users can create their own yield products without permissions, and the app offers a switch to curator mode.
05
Portfolio and investment views
The interface has Portfolio, Market and Investment sections to track and manage positions.
06
Multi-chain deployment
DefiLlama lists deployments on 13 chains including Ethereum, Base, Arbitrum, Hyperliquid and Plume.
Pros and cons
What we like
- Permissionless design lets anyone create yield products, according to the project description.
- Fixed APY markets give users a way to lock in a return rather than take variable rates.
- Deployed on 13 chains, including Ethereum, Base, Arbitrum and Hyperliquid.
- Two audits are listed on DefiLlama and the app has an 'Audited by' label.
- No token, so there is no inflationary reward layer to worry about.
Watch out for
- TVL is only about $108K in the DefiLlama data, so markets may be thin and exits at size could be costly.
- Fee levels are not published publicly available, so costs are hard to compare before use.
- Yield tokenization and fixed-rate products are harder for newcomers than a simple deposit or swap.
- Spreading across 13 chains means more bridging, more contracts and more places for something to go wrong.
- Only two audits are listed, and the project doesn't say who performed them or what they covered.
- No native token is listed, so there is no governance or incentive layer to evaluate.
Napier fees
Napier's fees are not published publicly available. Its homepage shows APY figures but no fee schedule.
Expect to pay network gas on whichever chain you use, plus any protocol or swap fees shown in the app before you confirm a transaction. Check these figures for each market.
Is Napier safe?
DefiLlama lists two audits for Napier, but the project doesn't name the auditors, give dates or describe findings. Check the reports yourself. Audits reduce but do not remove smart-contract risk.
Using the protocol is non-custodial in principle, since you interact from your own wallet, but you carry smart-contract risk and the risk of the underlying yield-bearing assets. Multi-chain deployments add further risk. Public sources mention no hacks or incidents, and no regulatory status is stated. With about $108K TVL, the protocol has little track record at scale.
6 steps
How to get started with Napier
- 1
Read the documentation and the audit reports linked from the app so you understand how yield tokenization works.
- 2
Pick a chain and a wallet that supports it, then fund it with the asset and gas token the market needs.
- 3
Open the Market page and compare Pool APY and Fixed APY, plus each market's maturity date.
- 4
Start with a small amount to learn how deposits, withdrawals and maturity work.
- 5
Track the position on the Portfolio page and review it before maturity.
- 6
If you want to create markets, look at the curator mode and its requirements first.
Who Napier is for
Napier is aimed at experienced DeFi users who want to fix a yield, speculate on variable yield or run their own yield markets. It is a poor fit for beginners and for anyone who needs deep liquidity.
Napier FAQs
What is Napier?
Napier is a modular yield tokenization protocol. According to its DefiLlama description, it lets users own, manage and create yield products without permissions.
Which chains does Napier support?
DefiLlama lists Ethereum, Robinhood Chain, Base, Sonic, Arbitrum, Hyperliquid, Polygon, Fraxtal, Optimism, Mantle, Avalanche, Plume and BNB Chain. Which markets are available on each chain is shown in the app.
Does Napier have a token?
No. DefiLlama shows no token for Napier, so there is no native token to buy, stake or use for governance based on public sources.
Is Napier audited?
DefiLlama lists two audits, but the project doesn't name the auditors or the scope. The homepage shows an 'Audited by' label, so check the audit reports before depositing. An audit reduces risk but does not remove it.
What do Pool APY and Fixed APY mean on Napier?
The app shows Pool APY and Fixed APY figures per market. Fixed APY generally refers to locking in a rate until a market's maturity, but check each market's terms in the app.
What is the curator mode?
Public sources mention a 'Switch to curator' option in the interface, which suggests a role for people who set up or manage markets. Details of how it works are not published publicly, so check the app.
