Our verdict on Mero
Mero is no longer a usable product. It was an Ethereum yield protocol with keeper-driven pools, and the team shut it down on July 4, 2024. The only reason to look at it now is if you still hold funds in its pools. In that case, use the contract addresses from the official shutdown notice and withdraw directly, taking care with addresses and gas costs. Anyone looking for yield today should choose an actively maintained protocol.

What is Mero?
Mero was a yield protocol on Ethereum. It described itself as delegating liquidity to where it is most efficient, using multi-utility liquidity pools, yield-farming strategies, off-chain keeper bots and customizable Actions. DefiLlama lists it under Yield, tracked since July 2022.
The project is no longer operating. A notice on the official Medium blog states that Mero was officially shut down as of July 4, 2024. The front-end was deprecated and deposits were closed.
DefiLlama still shows a small TVL of roughly $88,000, which likely reflects funds left in contracts. The Mero Twitter and Discord remain open but are not maintained. DefiLlama lists two audits, though public sources give no details.
How Mero works
Mero was a yield protocol on Ethereum. Users deposited assets such as DAI, ETH or USDC into pools and received pool tokens in return. The protocol then deployed that liquidity into yield-farming strategies.
Off-chain bots called keepers carried out automated tasks, and users could set up customizable Actions. The aim, in the project's words, was to delegate liquidity to where it was most efficient.
The protocol is now wound down. Users with remaining balances must redeem them directly through the pool smart contracts, since the official front-end no longer supports withdrawals.

Pros and cons
What we like
- Clear, public shutdown notice with contract addresses for direct withdrawal
- Two audits listed on DefiLlama
- Pools covered major assets such as DAI, ETH, USDC, USDT and FRAX
- Funds remain withdrawable from the contracts even after the front-end closed
Watch out for
- The protocol was shut down on July 4, 2024, so no new deposits are possible
- The official front-end is deprecated and withdrawals through it ended on January 1, 2025
- Users who still hold funds must interact with the contracts directly, which carries technical and error risk
- Official Twitter and Discord accounts are no longer maintained, so support is unlikely
- Remaining TVL is very small (about $88,000 per DefiLlama), and the data may be stale
Mero fees
Fees are not stated. Because the protocol is wound down, there is no current fee schedule to rely on.
Users who still need to withdraw from the contracts directly will pay Ethereum network gas fees, which vary with network demand.
Is Mero safe?
The main risk now is that the protocol is shut down. Users who still hold funds must withdraw by interacting with the contracts directly, since the official front-end stopped supporting withdrawals after January 1, 2025. Mistakes such as using a wrong address or a phishing link can cost funds.
DefiLlama lists two audits for Mero, but the project does not name the auditors or findings, and an audit does not remove smart-contract risk. No hacks are mentioned publicly. Since official accounts are unmaintained, treat any unsolicited support messages as likely scams.
6 steps
How to get started with Mero
- 1
Do not deposit: the protocol is shut down and the front-end is deprecated.
- 2
If you still hold Mero pool tokens, find the pool contract address in the official shutdown notice on Medium.
- 3
Verify the address against the official notice and avoid links from unofficial sources.
- 4
Connect a wallet to a reputable block explorer or contract interface and call the withdrawal function on the correct pool.
- 5
Check Ethereum gas costs before sending the transaction, and consider a small test first if you are unsure.
- 6
Consider seeking technical help if you are unfamiliar with direct contract interaction.
