Compare price impact, liquidity and slippage tolerance. Private routing may reduce some exposure but introduces its own intermediaries and guarantees.
Inspect the block
Compare quote and result
Check their limits
Understand ordering
Participants seek value from selecting or sequencing operations. A visible trade may create an arbitrage or sandwich opportunity.
Measure cost
Before signing compare quoted price, minimum received, pool depth, fees and timing. A very wide tolerance increases exposure.
Choose safeguards
Limit orders or some private routes can reduce specific risks. Inspect who receives the order, censorship possibilities and failure terms.
Review execution
Compare your trade with neighboring transactions and pool events. Price differences can also come from ordinary volatility or thin liquidity.
Compare quote and execution
A gap between quoted and final price alone does not prove an attack. Compare minimum received, nearby transactions, pool size and wider market movement.
- Avoid an unnecessarily wide slippage tolerance.
- A private route brings its own access and censorship rules.
Practical case: decision and limits
A swap sets a wide tolerance to “go through at any price”. That can increase exposure to poor execution and some sandwich strategies. Tolerance is not a fixed fee; it bounds acceptable deviation. Inspect liquidity, minimum output and deadline. A private route can reduce some visibility but adds a provider and guarantees neither execution nor absence of MEV.
A concrete verification
Compare signed minimum and outcome: meeting tolerance does not prevent unfavorable execution.
