MEV Protection for Traders: How to Avoid Front-Running

In our experience, traders executing large swaps on DEXs without MEV protection consistently receive worse fills than expected, and those who route through private mempools or use DEX aggregators

Relay Settings Calculations

To avoid relay mal-operation, set Slope 2 as high as possible. Normally, a high Slope 2 setting causes slow tripping for evolving faults (external-to-internal faults).

Relay Setting in Real Power System
