What is

Front‑running?

Front‑running — извлечение прибыли за счёт исполнения своей транзакции раньше вашей, увидев её в мемпуле.

Front‑running возникает, когда атакующий наблюдает вашу ожидающую транзакцию и отправляет свою с более высокой комиссией, чтобы попасть в блок первой. В DeFi это часто используется для получения выгоды за ваш счёт. Дизайн модели исполнения и рыночной структуры (например, eUTXO и атомарные сделки) может существенно усложнять такие атаки.

Key Points

  • Использует информацию из мемпула о вашей транзакции
  • Часто встречается на DEX в account‑based моделях
  • Ведёт к скрытым потерям для пользователей (MEV‑сценарии)
  • Снижается архитектурными решениями и защитами протокола

Use Cases

1

MEV‑стратегии на DEX

2

Сэндвич‑атаки как частный случай (в некоторых сетях)

3

Защита пользователей через дизайн протокола

Frequently Asked Questions

Questions about Front‑running

Common questions about this topic

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 build DeFi on Ergo?

Building DeFi on Ergo starts with understanding the eUTXO model and ErgoScript. Unlike account-based chains, Ergo's box model provides deterministic execution, no MEV by design, and predictable gas costs. Use Oracle Pools for price feeds, and leverage existing patterns from Spectrum Finance and SigmaUSD.

Is Ergo better than Ethereum for DeFi?

Ergo offers structural advantages for DeFi: no MEV extraction, deterministic gas costs, and no reentrancy attacks due to eUTXO. Ethereum has larger ecosystem and liquidity. Choose Ergo for security-critical applications, fair trading, and predictable costs. Choose Ethereum for maximum composability with existing protocols.
