What is
Mempool?
The waiting area for unconfirmed transactions before they're included in a block.
The mempool (memory pool) holds valid transactions waiting for block inclusion. Miners select transactions from the mempool, typically prioritizing higher fees. On Ergo, the eUTXO model means transactions reference specific boxes, reducing mempool complexity and preventing certain MEV attacks.
Key Points
- Holds pending transactions
- Miners select from mempool
- Higher fees = faster inclusion
- Each node has its own mempool
- Transactions expire if not mined
- eUTXO reduces mempool conflicts

Common questions about this topic
How do miners earn money on Ergo?
Ergo miners earn from three sources: block rewards (newly minted ERG), transaction fees, and storage rent. Block rewards decrease over time according to the emission schedule, but storage rent ensures long-term income even after all ERG is mined. Most miners use pools for consistent payouts.

How to get started with Ergo?
Start by getting a wallet (Nautilus for browser, Terminus for mobile). Back up your seed phrase securely offline. Get some ERG from a current exchange or verified venue, then make a small test transaction. After that, explore NFTs, mining, DeFi references, or the developer stack if you're a builder.

Is Ergo mining profitable in 2025?
Ergo mining profitability depends on your electricity cost, GPU efficiency, network difficulty, pool fees, and ERG price. Use mining calculators with your specific hardware and power costs. Autolykos is designed to keep GPU mining viable, but profitability changes with market and network conditions.

How to provide liquidity on Ergo?
Providing liquidity on Ergo depends on the current active DEX or AMM venue. In general, you deposit equal value of two assets into a pool, receive LP tokens representing your share, and earn a portion of trading fees. Spectrum Finance is historical/frozen since February 2024, so verify the active venue, contracts, liquidity depth, and withdrawal process before depositing funds.
