What is
MEV‑устойчивость?
MEV‑устойчивость — свойство дизайна сети/модели исполнения, которое затрудняет извлечение прибыли через переупорядочивание или вставку транзакций (front‑running).
MEV (Maximal Extractable Value) возникает, когда участники могут менять порядок транзакций ради прибыли (сэндвич‑атаки, front‑running). MEV‑устойчивость означает, что архитектура и модель исполнения уменьшают возможности для таких атак, делая исполнение более честным для пользователей.
Key Points
- MEV часто бьёт по пользователям DEX
- Проявляется как front‑running и сэндвич‑атаки
- MEV‑устойчивость повышает честность исполнения
- В eUTXO некоторые сценарии существенно сложнее
Use Cases
1
Более честные сделки на DEX
2
Меньше скрытых «налогов» от MEV‑ботов
3
Предсказуемое исполнение в финансовых приложениях
Technical Details
In account-based chains, miners can see pending transactions and insert their own to profit (front-running). Ergo's eUTXO model uses local state - each transaction specifies exact inputs and outputs. This determinism makes it harder to profitably reorder transactions, as outcomes are predictable before submission.

Questions about MEV‑устойчивость
Common questions about this topic
What is MEV resistance and why does Ergo have it?
MEV (Maximal Extractable Value) is profit extracted by reordering, inserting, or censoring transactions - think front-running and sandwich attacks. Ergo's eUTXO model provides structural MEV resistance: transactions reference specific boxes (UTXOs), making reordering attacks much harder. There's no shared global state to exploit like in account-based chains.

How to use Spectrum DEX on Ergo?
Connect your Nautilus wallet to Spectrum Finance, select tokens to swap, review the rate and slippage, then confirm. Spectrum uses AMM liquidity pools for instant trades. You can also provide liquidity to earn fees. All trades are atomic - they complete fully or not at all, with no front-running possible.

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 an exchange (Gate.io, KuCoin) or DEX (Spectrum). Make a test transaction. Then explore: try DeFi on Spectrum, check out NFTs, or dive into the technology if you're a builder.
