5/8 — MEV Mitigation — Lesson outline

RouteFollow this to avoid forgetting protections.

struct OrderflowPlan {
    bool usePrivateRpc;
    uint256 slippageBps;
    uint256 deadlineSecs;
    address relayer;
}

function planDefaults() internal pure returns (OrderflowPlan memory p) {
    p.usePrivateRpc = true;
    p.slippageBps = 50; // 0.5%
    p.deadlineSecs = 120;
}

Turn the outline into code/UX defaults so you can test and ship them.

Steps

Map the MEV supply:Chain for your app (where does intent leak?).
Decide on orderflow (private:RPC, bundle, or intent relayer) and fallbacks.
Design slippage/deadline policy and:UX defaults.
Implement an intent-based swap:Forwarder with signatures + replay guards.
Test sandwiches/backruns in public:Vs private submission paths.
Monitor relayer/builder health and:Add toggles if they fail.
