YearRing is a non-custodial fund protocol built on Base. Deposit USDC, earn real yield through Aave V3, and hold your position inside a structured, governed, and fully transparent management container — without delegating custody to anyone.
YearRing is building long-term on-chain capital infrastructure. Start where you fit best.

They want a structure they can trust — one that is transparent, governed, and designed to protect them before it grows.
YearRing Fund is an on-chain capital management protocol. It accepts USDC deposits, issues ERC-4626 shares (yrUSDC), and deploys capital into conservative yield strategies. The first and current strategy is Aave V3 USDC supply on Base.
The protocol adds a structured management layer on top of strategy yield: on-chain reserve ratios, a permanent emergency exit path, and role separation between normal administration and emergency response. Timelock governance and multisig are planned and will be implemented before any allowlist expansion.
YearRing is built and operated by a small, focused team. The contracts are open source, verified on BaseScan, and designed to be independently reviewable. There is no venture funding to announce, no advisory board to display, and no partnership logos to borrow credibility from. The protocol is the product. The code is the proof.
Current status: live on Base Mainnet under invited allowlist access. Formal audit in preparation. Allowlist expansion will follow audit completion.
Most on-chain yield today is accessed the same way: deposit into a protocol, earn a rate, watch it manually. There is no management layer. No reserve policy that protects your exit. No governed delay before a parameter that affects your capital can change. No unified accounting that tells you clearly what your position is worth.
That is not a criticism of yield protocols — it is a description of scope. Aave is lending infrastructure. It was not designed to manage capital on your behalf. YearRing was.
We exist because there is a gap between "access to yield" and "capital that is being managed well" — and closing that gap requires structure, not just a better rate.
You should use Aave directly if all you want is yield access. It is excellent at that. The question is whether yield access is sufficient for your goals.
When you deposit into Aave, you hold an aToken. It accrues interest. There is no management layer between you and the strategy. Every parameter — interest rate model, collateral factor, reserve factor — can change without your involvement and without advance notice.
That is a deliberate design decision by Aave — optimised for protocol flexibility, not depositor predictability. YearRing makes the opposite trade: less flexibility at the protocol layer, more protection at the depositor layer.
If you want to know — before you deposit — exactly what governance delay applies to your capital, what reserve protects your exit, and what conditions would trigger an emergency return of funds: that is what YearRing is for.

YearRing Fund Protocol is experimental software. Smart contracts have not been formally audited by a third party. The protocol operates under a limited-access allowlist while audit preparation is underway.
There are no guaranteed returns. Deposited capital is subject to smart contract risk, strategy risk (Aave V3 protocol conditions), and market risk. Price Per Share can decrease if the underlying strategy incurs losses.
Nothing on this website constitutes investment advice, a solicitation, or an offer to buy or sell any financial instrument. Users should independently evaluate all risks before interacting with the protocol.
Only interact with contracts and interfaces listed in the Official Channels section above. The protocol is non-custodial — you are solely responsible for the security of your wallet and private keys.
