Our verdict on YLDR
YLDR was an interesting niche lending protocol for Uniswap V3 liquidity providers, but the official site now says it is shutting down, so it is not a place to start new positions. Its strengths were a clear concept, a CertiK audit and non-custodial design. The main caveat is the wind-down and very low TVL. Existing users should read the announcement and close positions; everyone else can treat it as a reference for how LP-collateral lending works.

What is YLDR?
YLDR described itself as the first lending protocol for Uniswap. It let liquidity providers leverage their Uniswap V3 positions or take loans against them, while others supplied liquidity to earn yield.
The official homepage now states that YLDR Protocol is shutting down and links to an announcement. DefiLlama still lists it under Lending on Ethereum, Polygon, Arbitrum and Base, with about $13,759 in TVL and a listing date of December 2023.
This page is a research summary based on the homepage and public listings.The project does not say when the shutdown takes effect, so check the announcement for the exact timeline.
How YLDR works
YLDR sat on top of Uniswap V3. A liquidity provider's position is normally locked in a pool, earning trading fees. YLDR let that position act as collateral so the owner could borrow more assets against it.
For leverage, the borrowed liquidity was added to the position in one transaction, which raises the share of trading fees earned. The homepage claimed up to 5x. Repaying the debt returned the original position to the owner's wallet.
On the other side, suppliers deposited assets into lending markets that borrowers drew on. The homepage describes these returns as delta-neutral. All of this is run by smart contracts, but leveraged positions can be liquidated if collateral value falls too far.

Key features

Leveraged LP positions
Users could post a Uniswap V3 position as collateral and borrow more liquidity in a single transaction. The homepage claimed fee boosts of up to 5x.
02
Loans against LP positions
Position holders could borrow digital assets against an LP position or other assets while still earning fees as liquidity providers.
03
Supply side lending
Suppliers could add liquidity to earn what the homepage calls delta-neutral returns.
04
Position return on repayment
Repaying the debt returned the original position or asset to the user's wallet.
05
Non-custodial design
The homepage describes operations as performed by smart contracts without the protocol controlling user assets.
06
Multi-chain deployment
The protocol was deployed on Ethereum, Polygon, Arbitrum and Base according to DefiLlama.
Pros and cons
What we like
- Non-custodial design, as described on the homepage, with withdrawals possible at any time
- Audited by CertiK according to the homepage
- Repaying debt returns the original LP position to the wallet
- Offered a niche use for idle Uniswap V3 positions
- Ran on several chains: Ethereum, Polygon, Arbitrum and Base
Watch out for
- The protocol is shutting down, so new users should not start using it
- TVL is only about $13,759 on DefiLlama, which is very small for a lending market
- No governance or native token is listed, so there is no token-based incentive layer
- Only the CertiK audit is named on the homepage; the audit report details are not public
- Shutdown details are in an announcement that is not reproduced, so exit steps and timelines are unclear
- Leveraged LP positions carry liquidation and impermanent-loss risk
YLDR fees
YLDR's fees are not published. They included borrow rates for borrowers and yield for suppliers, but no figures are given.
Because the protocol is shutting down, anyone with an open position should check rates, accrued interest and repayment costs in the app and the official announcement. Normal network gas fees also apply on whichever chain is used.
Is YLDR safe?
The homepage says the smart contracts were audited by CertiK, and DefiLlama lists two audits. It also describes the protocol as non-custodial and run by smart contracts. The project does not include audit findings, so we cannot say what issues were raised or fixed.
The main current risk is the shutdown. Users with open positions should act on the official announcement, avoid look-alike sites, and confirm the address before signing anything. Leveraged LP positions can also be liquidated, and TVL is tiny, which suggests limited market depth. No incidents are mentioned publicly.

YLDR FAQs
What is YLDR?
YLDR was a lending protocol built around Uniswap V3 liquidity positions. Users could leverage an LP position or borrow against it, and others could supply liquidity to earn yield.
Is YLDR shutting down?
The homepage says YLDR Protocol is shutting down and links to an announcement. The project does not include the announcement's contents, so read it on the official site for dates and withdrawal instructions.
How do I get my funds or LP position back from YLDR?
The homepage says users can repay their debt and get the original position or asset back in their wallet, and that the protocol is non-custodial. Anyone with open positions should check the shutdown announcement and the app's transaction history promptly.
Which chains did YLDR run on?
DefiLlama lists Ethereum, Polygon, Arbitrum and Base. The app page surfaced in public reporting shows Arbitrum.
Does YLDR have a token?
DefiLlama lists no token for YLDR. Public reporting mentions a token portfolio page and airdrop guides from third parties, but the project does not confirm any YLDR token.
Was YLDR audited?
The homepage says the smart contracts were audited by CertiK. DefiLlama lists two audits in total. Audits reduce but do not remove smart-contract risk, and a protocol winding down adds its own operational risk.
