Concentrator Review 2026: Curve and Convex Yield Vaults

Concentrator is a yield protocol on Ethereum built by AladdinDAO. DefiLlama describes it as a platform that boosts rewards for Curve and Convex stakers and liquidity providers through a simple interface. It has been listed since March 2022.

The app offers Compounders and Harvesters. Compounders hold single-asset vaults like aFXN, arUSD, fxSAVE and asdPENDLE. Harvesters cover dozens of Curve-style LP pools and feed their rewards into the compounders.

DefiLlama shows about $86.2 million in TVL, down 2.2% over seven days, and two audits. The homepage labels the project as beta and tells users to use it at their own risk. The native token is CTR, and the app includes Lock, Vesting, YB Airdrop and Governance sections.

Curve and Convex let users stake tokens and provide liquidity to earn rewards. Claiming, selling and reinvesting those rewards takes time and gas. Concentrator pools many users' deposits so those steps happen together, which spreads the gas cost across depositors.

There are two main product types. Compounders auto-compound yield from DeFi blue-chip tokens in vaults like aFXN, arUSD, fxSAVE and asdPENDLE. Harvesters automatically claim, convert and deposit yield into the compounders, so a user's LP position can feed into the higher-yield vaults.

Deposits go into smart contracts, and returns come from the underlying protocols' rewards, so the protocol relies on Curve, Convex, Frax and Stake DAO working as intended. The yield shown by the app is a rate and not a guaranteed return.

Fee information is partial. A search result from the project's docs says Concentrator takes a 10% treasury fee and a 1% harvest fee on yield from arUSD and aFXN. The fees are collected during the harvest process.

Fees for the other harvesters and compounders are not stated publicly. Users also pay Ethereum gas costs, and underlying protocols such as Curve may charge their own fees. Check each vault's details in the app and the docs before depositing.

DefiLlama lists two audits and the homepage says audited and verified. The project does not name the auditors or give report details, so check the documentation. A security bounty program is mentioned in the project docs navigation.

The homepage states the project is in beta and to use it at your own risk. Funds sit in smart contracts that depend on other protocols such as Curve, Convex, Frax and Stake DAO, so risk is layered. Stablecoin and derivative tokens within pools carry their own depeg risk. No hack or incident is mentioned publicly, but that is not proof none has occurred. Do not deposit more than you can afford to lose.

Concentrator is for intermediate to advanced DeFi users on Ethereum who already use Curve, Convex or Frax-related assets and accept smart-contract and protocol-dependency risk. It is less suitable for beginners or anyone who wants guaranteed returns.
