Сабақ қорытындысы

MEV is value gained by changing transaction ordering, inclusion, or timing.

Mental model

MEV and Layer-2 Infrastructure, without the jargon

MEV is value gained by changing transaction ordering, inclusion, or timing. It exists because block producers have power over how pending transactions become blocks.

Mechanics

How to reason about MEV and layer-2 infrastructure

Searchers look for arbitrage, liquidations, and sandwich opportunities.

Builders and validators decide which bundles or transactions enter a block.

Rollups add another layer because sequencers often control ordering before settlement.

Example

MEV and Layer-2 Infrastructure, applied

If a large swap is visible before execution, a searcher may trade before and after it, extracting value from the price movement the user creates.

Есте сақтаңызDecision rule: For large on-chain trades, consider MEV protection, slippage settings, and liquidity depth before signing.

Common mistakes

Where people slip up with MEV and layer-2 infrastructure

MEV is not only an advanced trading topic. It affects normal users through worse execution, failed transactions, and higher costs.

Risk notes

Reading the risk in MEV and layer-2 infrastructure

Centralized sequencing, private order flow, and opaque builder markets can concentrate value and weaken user execution quality.

Define MEV in plain language.
Explain sandwich risk.
Check execution protection for large swaps.

Practice

Turn MEV and layer-2 infrastructure into a habit

Define MEV in plain language.
